NFIRS 5.0 COMPLETE REFERENCE GUIDE

FOREWORD
In 1972, the President’s Commission on Fire Prevention and Control published America Burning. This document was the first in-depth discussion of this country’s fire problem. An outgrowth of America Burning was
the National Fire Prevention and Control Act, Public Law 93–498, which established the National Fire
Prevention and Control Administration.
One of the results of the P.L. 93–498 mandate to collect national data on fires was the establishment of the
National Fire Incident Reporting System (NFIRS). In 1976, six States piloted what eventually evolved into
NFIRS. The U.S. Fire Administration (USFA), a component of the Department of Homeland Security (DHS),
developed NFIRS as a means of assessing the nature and scope of the fire problem in the United States.
NFIRS has grown in both participation and use. Over the life of the system, all 50 States, more than 40
major metropolitan areas, and more than 15,000 fire departments have participated in NFIRS. On a yearly
basis, approximately 600,000 fire incidents and more than 5 million non-fire incidents are added to the
database. NFIRS is the world’s largest collection of incidents to which fire departments respond.
NFIRS data are used at all levels of government. At the local level, incident and casualty information is used
for setting priorities and targeting resources. The data now being collected are particularly useful for designing fire prevention and educational programs and emergency medical service (EMS)-related activities
specifically suited to the real emergency problems the local community faces.
On the State level, NFIRS is used in many capacities. One valuable contribution is that NFIRS data are used
by State legislatures to justify budgets and to pass important bills on fire-related issues such as sprinklers,
fireworks, and arson.
Many Federal agencies, in addition to USFA, make use of NFIRS data—the Consumer Product Safety Commission (CPSC), the National Highway Traffic Safety Administration (NHTSA), the National Institute of
Standards and Technology (NIST), to name a few. The CPSC has found NFIRS very useful in identifying
potentially hazardous products.
Nationally, NFIRS is used by various private industries, including national associations for home appliance
product manufacturers, the hotel and motel industry, insurance companies, and attorneys.
Because NFIRS is a voluntary system, not all States or fire departments within States participate. In 1977,
only 6 States regularly reported data to the National Fire Data Center (NFDC), and 19 others had data systems in some stage of development. Since then, participation has increased significantly so that an estimated 44 percent of all U.S. fires to which fire departments respond are captured in NFIRS.
States have the flexibility to adapt their state reporting systems to their specific needs, and reporting by
localities is voluntary. Therefore, the design of a state’s data collection system varies from state to state.
However, NFIRS was designed so that data from state systems can be converted to a single format that is
used at the national level to aggregate and store NFIRS data.

FOREWORD
As participation in NFIRS increased, the system itself has undergone revisions and updates. The latest update of the system is Version 5.0, which provides many improvements both from the standpoint of those
who submit the data and for those who use it. This reference guide provides step-by-step instructions for
submitting fire incident information to NFIRS 5.0.
Comments and suggestions on further improvements to this guide are solicited and should be submitted to National Fire Data Center, U.S. Fire Administration, Department of Homeland Security, 16825 South

INTRODUCTION

NFIRS 5.0 COMPLETE REFERENCE GUIDE

Chapter 1 • Introduction
This reference guide is a component of the National Fire Incident Reporting System (NFIRS) Version 5.0. It
provides both instructions for reporting data to NFIRS Version 5.0 and an understanding of the data elements collected by the system. It also serves as a reference for the coding of the data. NFIRS (pronounced
“en-furs”) is a tool that fire departments use both to report fires and other incidents to which fire departments respond and to maintain records of these incidents in a uniform manner.
NFIRS 5.0 is a modular, all-incident reporting system designed by the U.S. Fire Administration (USFA), a
part of the Department of Homeland Security (DHS), with input from the fire service and other users of
the data.

How NFIRS Works
In 2001, more than 12,000 fire departments participated in NFIRS. After responding to an incident, fire
department personnel complete one or more of the NFIRS “modules.” The information in these modules
describes the kind of incident responded to, where it occurred, the resources used to mitigate it, and how
losses and other information designed specifically to understand the nature and causes of fire, hazardous
material (HazMat), and emergency medical service (EMS) incidents. Information is also collected on the
number of civilian or firefighter casualties and an estimate of property loss. The uniformity of definitions
used in coding NFIRS fields makes aggregation of national data possible.
Information is entered about an emergency response either manually on a form or directly through a computer. Local agencies forward the completed NFIRS modules to the State agency responsible for NFIRS data.
The State agency combines the information with data from other fire departments into a statewide database and then transmits the data to the National Fire Data Center (NFDC) at the USFA. The NFDC can then
compare and contrast statistics from States and large metropolitan departments to develop national public
education campaigns, make recommendations for national codes and standards, guide allocation of Federal
funds, determine consumer product failures, identify the focus for research efforts, and support Federal
legislation. NFIRS is the primary source of data for a wide range of analyses and reports, including USFA’s
publication Fire in the United States, which is the single most comprehensive reference on the nature and scope
of the fire problem in the United States.
At the national level, data combined from participating States are also used by information partners, as
shown in the following graphic.

NFIRS Version 5.0 Enhancements
NFIRS 5.0 is an information-based system with data entry, data storage, and data retrieval, whether for a
single incident or in aggregate, aggregated via a computer that interacts with the database. Because not all
fire departments use computers for their recordkeeping, paper forms are available. Paper forms are forwarded to a central point where the data are entered to a database. This guide provides detailed instructions
for completing paper forms. Automated reporting systems, however, should be designed to capture the data
in the same order as these paper forms, so this guide is relevant to anyone who must collect and report
incident data.
In Version 5.0, a series of descriptions with assigned code numbers is used to describe incidents. Many of
these descriptive phrases were created by the National Fire Protection Association (NFPA) and published in
NFPA 901, Standard Classifications for Incident Reporting and Fire Protection Data, 1995 edition. Appropriate codes are
included in this user guide. Many improvements that have been incorporated into Version 5.0 are the result
of suggestions made by participating fire departments, State agencies, and the National Fire Information
Council (NFIC).

NFIRS 5.0 COMPLETE REFERENCE GUIDE

INTRODUCTION
The type and content of data collected by NFIRS 5.0 have evolved over more than 25 years and are based
on the participation of all 50 States and more than 40 metropolitan fire departments. NFIRS 5.0 captures
information on all incidents to which a fire department responds. In addition to many data coding improvements, Version 5.0 provides five new modules that recognize the increasingly diverse activities of fire
departments today: an EMS Module, a Wildland Fire Module, an Apparatus Module, a Personnel Module,
and an Arson Module. Other modules have been extensively revised.
The modular design of NFIRS 5.0 makes the system easier to use than previous NFIRS versions because it
captures only the data required to profile the extent of the incident. Some fires, for example, require just
basic information, whereas others require considerably more detail. The accuracy and reliability of the collected data are improved because of the way questions are asked and data are coded.
The selection of data elements and the coding selections for the data have been revised to reduce confusion or improve data quality. For example, codes using 9 to indicate “not otherwise classified” have been
changed to the value of 0 (zero) where it may be necessary to code something as “other.” The internal
codes for “insufficient information to classify further” have been eliminated. A single code of “U” (or
“UU” or “UUU” depending on field size) is available to designate “unknown” or “undetermined.” Although NFIRS Version 4.1 allowed a distinction between the 9 code (“not otherwise classified”) and the 0
code (“insufficient information to classify further”), the distinction between these codes was often unclear
to the respondent.
Other improvements incorporated in NFIRS 5.0 include:
• Compound data elements have been eliminated. Some of the previous data elements asked for multiple
pieces of information. NFIRS 5.0 splits these data elements into single-issue questions to eliminate
often confusing and ambiguous or incorrect answers. Although this increased the number of fields or
questions being asked, the choices are clearer and the number of codes has decreased. For example,
“Equipment Involved in Ignition” in Version 4.1 is a complex list of equipment that not only identifies
the equipment, but also includes data on its power source and portability. Version 5.0 has three categories (Equipment, Equipment Portability, and Equipment Power Source) that makes coding easier, more
accurate, and more specific.
• Contained, no-loss fires are simply reported using only the Basic Module, with as few as three codes
having to be looked up and entered when using the paper forms.
• Small spills of common hazardous materials are documented only in the Basic Module instead of requiring the fire department to complete all the details that are necessary for spills that are more significant. Detailed information is completed on the HazMat Module (NFIRS–7) if a serious release of
hazardous materials occurs.
• Reporting the failures of protective clothing and equipment worn or used by firefighters has been simplified to focus only on items whose failure contributed to a casualty (i.e., injury or fatality).
For convenience to users familiar with the codes of NFIRS 4.1, references are provided in this guide to the
titles of the NFIRS 4.1 code lists that have changed in NFIRS 5.0.

INTRODUCTION

Benefits of NFIRS to Firefighters
Firefighters will find that NFIRS 5.0 is easier to use than previous versions. Also, two of the new modules,
Apparatus and Personnel, will assist fire departments in managing apparatus, personnel, and resources.
Each fire department is responsible for planning and managing its operations so that firefighters can perform their roles of fire control and fire prevention most effectively and efficiently. The availability of accurate information about fires and other incidents is vital in achieving maximum performance. Patterns that
emerge from the analysis of incident data can help departments focus on current problems, predict future
problems in their communities, and measure their programs' performance.

Coding
In 1963, NFPA formed a technical committee to devise a uniform system of fire reporting to encourage
fire departments to use a common set of definitions. NFPA 901, Standard Classifications for Incident Reporting and
Fire Protection Data, was developed as a dictionary of fire terminology and associated numerical codes. As the
fire service gained experience with this fire data “language,” continuous improvements have been possible.
The set of codes used in NFIRS 5.0 represents the merging of the ideas from NFPA 901 with the many suggested improvements from users of the NFIRS 4.1 coding system.

Structure of the User Guide
Chapter 2 briefly describes the 11 NFIRS modules, provides general guidance on when each module
should be used, and details standard conventions that are to be used when completing these modules.
Chapters 3 through 13 cover NFIRS modules 1 through 11, respectively, in detail. Guidance is provided on
how each field of the module form should be completed and defines the codes that are used in the system.
Chapter 14 addresses information that might be submitted on a supplemental form (NFIRS–1S). Full-size
replicas of all NFIRS forms are found in Appendix A.
Appendix B is an index of NFIRS 5.0 synonyms of selected code lists that have been alphabetized. Appendix
C is a glossary of terms and abbreviations. Appendix D is an alphabetized listing of chemicals and hazardous materials.

NFIRS 5.0 MODULES

NFIRS 5.0 COMPLETE REFERENCE GUIDE

Chapter 2•NFIRS 5.0 Modules
NFIRS Version 5.0 consists of 11 modules. The Basic Module is to be completed for every incident, with
additional modules used as appropriate to describe the incident.

Description of Modules
The Basic Module (NFIRS–1) captures general information on every incident (or emergency call) to which
the department responds.
THE FOLLOWING MODULES ARE USED IN CONJUNCTION WITH THE
BASIC MODULE, WHICH MUST BE COMPLETED FOR EVERY INCIDENT TO
WHICH YOUR DEPARTMENT RESPONDS

The Fire Module (NFIRS–2) is used to describe each fire incident to which the department responds. For
wildland fire incidents, the Wildland Module can be used instead of the Fire Module if that option is available by your State reporting authority.
The Structure Fire Module (NFIRS–3) is used to describe each structure fire to which the department responds. This module is used in conjunction with the Fire Module.
The Civilian Fire Casualty Module (NFIRS–4) is used to report injuries or deaths to civilians or other emergency personnel (e.g., police officers, non-fire department/EMS personnel) that are related to a fire incident.
This module is used in conjunction with the Fire Module and, if applicable, the Structure Fire Module.
Non-fire-related injuries or deaths to civilians can be reported on the EMS Module.
The Fire Service Casualty Module (NFIRS–5) is used to report injuries and deaths of firefighters. The module
can also be used to report the exposure of a firefighter to chemicals or biological agents at an incident
where that exposure does not result in any symptoms at that time but that manifest themselves at a later
date. This module may be used with any of the other modules.
THE FOLLOWING MODULES (NFIRS–6 THROUGH –11) ARE
OPTIONAL MODULES THAT ARE USED ONLY WHEN THAT OPTION(S) IS
SELECTED BY YOUR STATE REPORTING AUTHORITY

The EMS Module (NFIRS–6) is completed by fire departments that provide emergency medical services. The
module is used to report all medical incidents where the department provided the primary patient care.
This includes incidents where there were civilian fire-related casualties and a Civilian Fire Casualty Module
was completed and where there were firefighter fire-related casualties and a Fire Service Casualty Module
was completed. (This module does not serve as a patient care record, but it can be used in conjunction
with the local requirements for patient care.)

NFIRS 5.0 COMPLETE REFERENCE GUIDE

2-2

CHAPTER 2 • NFIRS 5.0 MODULES
The Hazardous Materials Module (NFIRS–7) is completed to report spills or releases of 55 gallons or more of
hazardous materials or when special HazMat actions were taken. As appropriate, the module is used in conjunction with the Fire Module or other modules to provide detailed information about incidents involving
hazardous materials.
The Wildland Fire Module (NFIRS–8) is completed to report incidents that involve wildland or vegetation
fires. The module is used in lieu of the Fire Module for wildland fire incidents.
The Apparatus or Resources Module (NFIRS–9), a department-use module, is completed to report data specific
to each piece of apparatus that responds to an incident. It includes information that can be used to calculate response time and time out of service. This module is not used if the Personnel Module is used.
The Personnel Module (NFIRS–10), a department-use module, is completed to report the same information
as on the Apparatus or Resources Module, but it also provides for tracking the personnel associated with
that apparatus.
The Arson Module (NFIRS–11) is completed to report additional information on fires that have been coded
by the department as “intentionally set.”
In addition to the 11 modules, a Supplemental Form (NFIRS–1S) can be used to report information on additional persons and entities involved in the incident and to collect additional special studies fields. This
paper-only form extends the amount of information collected in the Basic Module.

Preparation of Modules
Both local and State agencies should establish standard procedures on how to complete the NFIRS reporting modules and how to submit the modules to the State reporting activity. These procedures will help
ensure consistency in the data received and provide guidance to those filling out the modules. Each coded
field in the on-line NFIRS systems has the capability to be expanded by another alpha-numeric character so
that information more specific than the national standard addresses can be collected.
The majority of the information on the modules is obtained at the scene by emergency responder personnel. An emergency responder at the scene should be assigned the responsibility of recording the required
information concerning each incident. To gather additional information or to confirm one’s own impressions, the individual completing the module should contact others involved with the incident. Contacts
may include on-scene fire service personnel, police and civilians at the scene, the dispatcher, EMS personnel, hospital staff, fire and building inspectors, the arson investigator, the local fire module coordinator, and
State-level officials responsible for coordinating the reporting system. Most importantly, the module should
reflect exactly what happened.
Once the module has been completed, the information should be reviewed at the local level before it is
signed by the officer in charge at the incident and by the individual completing the module. Originals
of the modules should be kept for departmental use and files, and copies forwarded to the State that will
transmit them to the NFDC.

2-3

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 2 • NFIRS 5.0 MODULES
Modifications to original incident reports can be submitted later when additional information becomes
available or if any of the original information changes or is found to be incorrect. A person injured in a fire
who dies within 1 year as a result of the injuries is an example of the type of new information that could
be cause for submitting a “change report.”
Once computerized, the data can be presented in a variety of ways, such as summaries, comparisons, and
reports. The web-based reporting tool made available to NFIRS users by the NFDC is able to produce a variety of reports. Many localities and departments develop data analysis and display programs to meet their
own requirements. For more information concerning the new NFIRS 5.0, contact the USFA or visit its Web
site at http://www.usfa.fema.gov/fireservice/nfirs/

Conventions Used in Completing Modules
Each time a fire service unit moves in response to an alarm, the Basic Module (NFIRS–1) must be completed. One report is completed for each incident. Other modules are completed as appropriate.
A form depicting the data for each module is shown at the beginning of that module’s chapter. The entire
set of forms (full-size) is included in Appendix A. The forms are divided into lettered sections, and blocks
divide sections. Blocks are formed by the section letter and the number of the block within the section
(e.g., Section A, Block A1). The different blocks within a section contain related information. The modules
are designed to help emergency personnel report incident information in a straightforward and orderly
manner. Many of the codes are printed on the paper modules to expedite the report process. For many situations, however, the correct codes will need to be looked up.
Modules should be completed according to the type of incident being reported. Instruction is given on the
module when necessary. All sections that have a star (P) by the title are required fields. Throughout this guide, notes
or important considerations are indicated with a pointed finger (*).
Each module is discussed one section at a time in the chapters that follow. Each item or block in each section is described by its definition, purpose, entry, and example. In addition, for those items requiring a
numerical code, the codes and a coded example are shown.
• The definition provides a common meaning for all, which ensures consistency in understanding and application.
• The purpose gives a brief explanation as to why the information has been requested; it may also indicate
how the information could be of additional use.
• The entry provides guidance on the type of information to place in the entry block.
• The example shows how the entry might look for a particular situation.

NFIRS 5.0 COMPLETE REFERENCE GUIDE

2-4

CHAPTER 2 • NFIRS 5.0 MODULES
Within the data coding used in this system, a few conventions assist in reporting. The letters “N,” “NN,” or
“NNN” are used to indicate “none” in a field that is normally coded. The letters “U,” “UU,” or “UUU” are
used to indicate “unknown” or “undetermined” in a field that is normally coded. If the field is a numeric
field such as dollar loss, 0 (zero) is used to indicate none. Numeric fields such as dollar loss can be left
blank if a value is unknown or if the incident is not a fire.
The coded field should not be left blank as that is an indication that the person completing the report
missed it or forgot to fill it out.
Please note that the numbers “0,” “00,” or “000” are valid codes for many coded fields. These have the
value for “other” and are intended to be used where the item or issue being coded is identifiable but the
code selection list does not contain the description of what has been identified for that data element. In
some data elements, codes ending in “0” allow for further identification of the item or issue, as in the case
where part of the answer is known but not enough to code it at the specific level required by the options
in the list.
The entry of data into fields should follow the following conventions:
• Text fields should be left justified.
• Numeric fields should be right justified.
• Coded fields do not need to be justified since they should fit the entry space exactly.

Fire Department Header
Before data may be entered into NFIRS 5.0, each fire department must have established a header record.
This record is established only once in the system and then updated whenever there is a change in the
department’s information.
Creation of or changes to the header record must be reviewed or approved by each department’s State
NFIRS program manager.
As a rule of thumb, if a department has a Fire Department Identification (FDID) number, a header has already been established. Most of the existing records were created from the conversion of NFIRS 4.1 header
records at the State level; however, many of the fields may be blank because they are new to NFIRS 5.0. It is
recommended that each department review their header record to ensure completeness.
The table on the following page shows the fire department header fields:

CHAPTER 3 • BASIC MODULE (NFIRS-1)

Chapter 3 • Basic Module (NFIRS-1)

he purpose of the Basic Module is to collect information common to all incidents. The Basic Module is
required for every type of incident to which a department responds.

Entries in the Basic Module determine what other modules need to be completed based on the type of
incident involved. For example, fire incidents are also reported on the Fire Module (NFIRS–2). Additionally,
the Structure Fire Module (NFIRS–3) is required if the fire reported in the Fire Module occurs in a structure.
A separate Civilian Fire Casualty Module (NFIRS–4) is required for each civilian who is injured as a direct
result of a fire incident. A separate Fire Service Casualty Module (NFIRS–5) is required for each firefighter
who is injured in response to an alarm whether or not a fire was involved.
Optional modules include the EMS, HazMat, Wildland Fire, Apparatus and Personnel, and Arson Modules.
The type of incident reported or the nature of a particular incident, such as the release of hazardous materials
at a fire after the arrival of the fire department, may trigger one or more of these additional modules. The
amount of information needed in each module varies based on the type of incident, associated casualties,
and property losses.
SECTION A

The field elements in Section A that are marked with a star (P) are required to be completed. Combined,
these fields (FDIC, State, Incident Date, Incident Number, and Exposure) uniquely identify each incident.
A

Fire Department Identification (FDID) P
Definition

A unique five-character identifier assigned by the State to identify a particular fire department within the
State. This identifier may also identify the county, fire district, or other jurisdiction in which the fire
department is located. Many States use the two left-most digits to identify the particular department within
a jurisdiction. All five spaces in this field must be occupied by numerals or alphanumeric characters. If the
FDID is less than five characters, use leading zeros.

Purpose

The FDID number is used to identify incident data that have been collected and reported by individual
departments. Feedback on local or regional incident experience can then be prepared and sent to
individual agencies or specific fire departments.

Entry

Enter the State-assigned FDID.

The P denotes a required field.

and must be the same as the date for the alarm time.

Purpose

In conjunction with other required Section A fields, this element uniquely identifies each incident.

Entry

Enter the month, day, and year (mm/dd/yyyy) that the initial incident alarm was received by the department. It must be entered for each incident.
The Incident Date is the same as the Alarm date (Block E1), except if the incident is an exposure and
the exposure occurs on a subsequent day.

Purpose

The station number provides a means of tracking incident data that have been collected and reported by
individual stations. Specific feedback on incident experience can then be prepared and sent to individual
stations. The station number is also useful for analyzing different levels of activity within a fire department.

Entry

Enter the station number in the space provided. The fire department should determine which station
number should be entered (e.g., first arriving unit, station’s area). The station number is left justified. Leave
blank if there is only one station in the department.

Exposure Number P
Definition

Exposure is defined as a fire resulting from another fire outside that building, structure, or vehicle, or a fire
that extends to an outside property from a building, structure, or vehicle. For example, if the building fire
ignites a truck parked outside, the truck fire is an exposure fire.
In the case of buildings with internal fire separations, treat the fire spread from one separation to
another as an exposure. Treating multiple ownership of property within a building (e.g., condominiums) as exposures, unless separated by fire-rated compartments, is discouraged.

The P denotes a required field.

3-7

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 3 • BASIC MODULE (NFIRS-1)

Purpose

Although the Incident Number permits all properties involved in a fire incident to be related together,
the Exposure Number identifies each separate property type involved in the fire. This makes it possible to
capture the specific details of the fire in each exposure and to relate all the exposures to the basic incident,
if necessary. The Exposure Number, in conjunction with other required Section A fields, uniquely identifies
each incident itemized in Section C.
When a fire involves more than one building, each building fire should be considered a separate fire, with
the ignition for all but the original building fire classified as exposure fires.

Entry

In a fire involving exposures, an additional Basic Module should be completed for each exposure. Each
module completed for an exposure should contain the same Incident Number assigned to the original
property involved. A separate sequential Exposure Number is assigned to each exposure. The original incident is always coded “000,” and exposures are numbered sequentially and incremented by 1 beginning
with “001.” The three-character numeric field is zero filled, not right justified.

Entry

Delete: Check or mark this box when you have previously submitted data on this incident and now want
to have the data on this incident deleted from the database. If this box is marked, complete Section A and
leave the rest of the report blank. This will delete all data regarding the incident. Forward the report according to your normally established procedures.
Change: Check or mark this box only if you previously submitted this fire incident to your State reporting authority and now want to update or change the information in the State database. Complete Section A and any
other sections or blocks that need to be updated or corrected. If you need to blank a field that contains data,
you must resubmit the original module containing the newly blanked field along with all the other original
information in the module for that incident. This action is required only when sending an updated module
to your State reporting authority. Forward the report according to your normally established procedures.
No Activity: If the fire department has had no incidents during the month, a no activity report should be
submitted. Unless otherwise specified by the State, this report should be submitted monthly according to
your normally established procedures.

Examples

Deleting a previously submitted incident:
Check or mark the Delete box and complete all other fields in Section A exactly as they were entered in the
original report.
Changing a previously submitted incident:
It was incorrectly reported that six firefighters responded to a fire incident. Later, the officer in charge
corrected the information and sent in a Change report with four fire service personnel responding:

SECTION B

Section B collects information on the specific incident location.
The check box at the top of the section should be checked or marked only if the incident address is
provided on the Wildland Fire Module (NFIRS–8). The Wildland Fire Module provides an alternative
method of recording the incident location.
B

Location Type P
The location of the incident, which may be a street address, directions from a recognized landmark, or an
intersection of two roadways.

Purpose

The exact location of the incident is used for spatial analyses and response planning that can be linked to
demographic data. Incident address information is required at the local government level to establish an
official document of record.

Entry

Check or mark the single box that best indicates the address type that will be entered. If the incident is a
wildland fire, the alternate address box at the top of Section B may be checked or marked to indicate that
the wildland location scheme is provided in the Wildland Fire module.
Street address: A normal street address. Check or mark this box and complete the address fields.

Intersection: There is no street address. The incident location is at the intersection of two or more streets,
roads, etc. Check or mark this box and enter the first street in the Street or Highway field. The intersecting street(s) is entered in the Cross Street or Directions field.
In front of: No street address is available. However, the incident location is in front of an area with a street
address. Check or mark this box and complete the address fields. An example of this might be a park,
plaza, or common area in front of a building with a street address.
Rear of: No street address is available. However, the incident location is in the rear of an area with a street
address. Check or mark this box and complete the address fields. An example of this might be an alley
that runs behind a building with a street address.

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 3 • BASIC MODULE (NFIRS-1)
Adjacent to: No street address is available. However, the incident location is adjacent to an area with a
street address. Check or mark this box and complete the address fields. An example of this might be an
empty lot or common area that is next to a building with a street address.
Directions: No street address is available and no street address is available near the incident scene. Check or
mark this box and enter brief directions for the location of the incident in the Cross Street or Directions
field. If the area is along an interstate or State highway, the closest milepost should be entered in the
Number/Milepost address field. An example of this might be a brush fire that occurs in a remote area
or a fire that occurs on or near an interstate highway.
United States National Grid: Provides a geospatial address based on universally defined coordinate and
grid systems and a common frame of reference across multiple jurisdictions easily extended worldwide. Using an alpha-numeric reference that overlays the UTM (q.v.) coordinate system, USNG spatial addresses break down into three parts: Grid Zone Designation, for a world-wide unique address;
100,000-meter Square Identification, for regional areas; Grid Coordinates, for local areas. USNG improves interoperability of location appliances with printed maps through a consistent and preferred
geospatial grid reference system. Relates to GPS (q.v.). Contributed by Tom May. (International). For more information and examples on use, see: http://www.xyproject.org/How%20To%20Read%20USNGHow%20

Cross Street, Directions or U.S. National Grid
Use directions only if the location cannot otherwise be identified. Enter USNG coordinates if U.S. National
Grid is selected for Location Type.

Definition

The nearest cross street to the incident address or directions from a recognized landmark or the second
street name of an intersection if Directions is selected as the Location Type. If U.S. National Grid is selected
as the Location Type, enter the USNG address (a geospatial address based on universally defined coordinate and grid systems and a common frame of reference across multiple jurisdictions easily extended
world-wide). Using an alpha-numeric reference that overlays the UTM (q.v.) coordinate system, USNG
spatial addresses break down into three parts: Grid Zone Designation, for a world-wide unique address;
100,000-meter Square Identification, for regional areas; Grid Coordinates, for local areas.

Purpose

This element helps determine the exact location of the incident. This information may also be useful for
identifying local problems, such as checking for multiple incidents at the same location.

Entry

In the space provided, describe the nearest cross street or provide directions from a recognized landmark.
The maximum number of characters available in the Cross Street or Directions field is 30. If U. S. National
Grid is selected as the Location type, the USNG coordinates of the incident location is entered using 10
digit precision at a minimum. The maximum entry is 15 characters. Note: USNG may also be used to
precisely describe the location of a Wildland Fire incident instead of Longitude/Latitude coordinates or
Township Ranges

Example

The incident occurred on 10th Street with N Street being the nearest cross street:

Check this box to indicate that the address for this incident is provided on the Wildland Fire

Module in Section B, "Alternative Location Specification." Use only for wildland fires.

Aid Given or Received P
Definition

Aid given or received, either automatically (i.e., prearranged) or mutually for a specific incident. These actions are defined as:
Aid Received (automatic or mutual): A fire department handles an incident within its jurisdiction with additional manpower or equipment from one or more fire departments outside its jurisdiction. Aid received
can be either mutual or automatic aid.
Aid Given (automatic or mutual): A fire department responds into another fire department’s jurisdiction to
provide assistance at an incident or to cover a vacated station while the receiving fire department is busy
at an incident. Aid given can be either mutual or automatic aid.

The P denotes a required field.

3-28

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 3 • BASIC MODULE (NFIRS-1)
Other Aid Given: A fire department covers and responds to another jurisdiction or locale that has no fire
department.
No Aid: A fire department handles an incident within its jurisdiction without help from adjacent or
outside fire departments.

Purpose

Aid information can be used to study response levels necessary to control various fire and emergency
situations. It can be used to determine the adequacy of resources at the local level and the need for
adjusting cooperative agreements. The Aid Given or Received entry serves as data control to ensure that
the same incident is not counted more than once while still giving credit for activity performed by
outside departments.

Entry

Check or mark the box indicating whether aid was given or received. If no aid was given or received,
check or mark the None box.
Unless otherwise stipulated, whenever the following instructions indicate completion of the “Basic
Module,” the appropriate supporting and optional modules must also be completed.
Mutual/Automatic Aid Received: If either of these boxes is checked or marked, complete the Basic Module.
Mutual/Automatic Aid Given: If your department provided automatic or mutual aid to another fire department, check or mark the appropriate aid-given box; complete their FDID, their State, and their Incident
Number fields; and complete the Basic Module through Block G1 (Resources). No other information is
required for the Basic Module unless a fire service casualty occurs. In this case, you must also complete
Block H1 (Casualties) and a Fire Service Casualty Module.
Other Aid Given: Check or mark this box if your department covers and responds to another jurisdiction or
locale that has no fire department. Complete the Basic Module. In Section D, leave their FDID and their
Incident Number fields blank; the State field is optional.
None: Check or mark this box if no mutual aid was involved.
If the receiving fire department completes the incident, then the giving department should complete the
required portion of the module as needed for its own documentation of the incident. This can be particularly
important for documenting fire service casualties.
Resources: If you give aid, you may choose to report your own resources as an option (Block G1).
Similarly, if you receive aid, you may choose to count only your own resources or count your own
resources plus those of the aid-giving department. If you include aid-received resources, check or
mark the corresponding box.
Casualties: The aid-receiving department reports the details on all casualties other than the fire service casualties of the aid-giving department. Each department reports the details on its own fire service casualties.

Controlled Time

Definition

The actual month, day, year, and time of day when the fire is brought under control or the incident is
stabilized and does not require additional emergency resources. “Controlled” is the time when the incident
commander determines that the fire will not escape from its containment perimeter.
* This is a required field for wildland fires.

Purpose

The time spent stabilizing a fire provides fire department management with the information needed to
analyze the duration patterns of different types of fires. This can assist in determining service demand and
costs for resource allocation.

Entry

Enter the month, day, year (mm/dd/yyyy), and time that the incident was controlled. If the date is the
same as the Alarm date, check or mark the corresponding box; do not reenter the date. However, if the
incident extended (from the Alarm time to the Controlled time) through midnight, do not check or mark
the box; instead, enter the date.

Alarms

Definition

The actual number of alarms transmitted for the incident. The definition of an alarm is determined at the
local level.

Purpose

The number of alarms is one method of measuring incident severity. Knowing the number of alarms can
be useful for local analysis of resource requirements. The number of alarms also may be related to mutual
aid support. This is a local option.

District

Definition

An area identified by the fire department that is useful for administrative purposes.

Purpose

Fire departments can develop their own method of locating the frequency and severity of incidents by
district. District numbers may identify specific townships, contract service areas, political wards, station
response areas, inspection or administrative districts, or any other boundary a department may wish to use.
This data element can be a powerful tool for local use. This is a local option.

Special Studies
Definition

Temporary data elements that can be used for collection of information that is of special interest for a
defined period. Special studies are typically required to capture information on emerging trends, problem
areas, or a specific issue being studied. When the answer becomes known through the special study, the
collection of that field is no longer required. If the data will always be needed for permanent collection, a
State- or department-defined permanent user field should be created and used instead of the Special Studies field. A State, a fire department, or the NFDC can define special studies.
Special Study ID Number: This number uniquely identifies each special study that is being run by the fire
department, State, or NFDC.
Special Study Value: The value in the field being collected. Responses for special studies can be defined as
codes or as alphanumeric entries of numeric values or dates. States, fire departments, and the NFDC can
define Special Studies fields.

Purpose

The use of special studies allows departments, States, and the NFDC to quickly collect information on an
issue or problem and to answer a specific question through the temporary use of a special study field over
a defined period of time. This is a State or local option.

Entry

If you are participating in a Special Study, your entry will depend on the type of data being collected. Use
the codeset defined for the particular Special Study field if it is a coded entry. The data entered may also be
a date or a numeric entry if the field has been so defined. Additional Special Study fields are available on the
Supplemental Form (NFIRS–1S).

Type of Material First Ignited
Type of Material First Ignited was known as Type of Material Ignited in NFIRS 4.1.

Definition

The composition of the material in the item first ignited by the heat source. The type of material ignited
refers to the raw, common, or natural state of the material. The type of material ignited may be a gas, flammable liquid, chemical, plastic, wood, paper, fabric, or any number of other materials.
This field is required only if the Item First Ignited code is “00” or a code less than “70.”

Purpose

This information assists in determining why fires start and spread and their severity. A study of this entry
also helps assess the need for flammability and other material characteristic standards. This information is
important to manufacturers for product improvement, as well as for fire prevention efforts.

Entry

Enter the code and description that best describes the type of material first ignited by the heat source.
Be certain to enter the first material ignited by the heat source. For example, if an arsonist poured gasoline on a wooden floor, it was the gasoline and not the wood that was the material first ignited.
If an insulated wire short circuits, it may be the wire’s insulation that was first ignited; or it may be the
wood studs in the wall, thermal insulation nearby, or another material.

Cause of Ignition P
Definition

The general causal factor that resulted in a heat source igniting a combustible material. The cause could be
the result of a deliberate act, mechanical failure, or act of nature.

Purpose

This information is used to determine if further information about the factors related to the fire’s ignition
will be collected later in the module. When combined with other data elements that make up the fire’s
“ignition chain,” it provides critical information about the nature of the events and the circumstances that
caused the fire. This is an important element in understanding the causes of fires.

Equipment Involved in Ignition
Equipment Type

Definition

The piece of equipment that provided the principal heat source to cause ignition.

Purpose

Analysis of the equipment involved in ignition is useful for improving product safety and preventive maintenance. It is just as important to know the kind of equipment that was used improperly as it is to know
the kind of equipment that malfunctioned. Misuse can be the direct result of the way the equipment is
designed and constructed. When involved in ignition, equipment information provides an important part
of the causal data. Equipment involved in ignition can be compared to other causal data to determine if the
equipment was (or was not) operating properly.

Entry

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 5 • STRUCTURE FIRE MODULE (NFIRS-3)

CHAPTER 5 • STRUCTURE FIRE MODULE (NFIRS–3)

he Structure Fire Module (NFIRS–3) should be completed for all structure fires. A structure is an assembly of materials forming a construction for occupancy or use to serve a specific purpose. This includes,
but is not limited to, buildings, open platforms, bridges, roof assemblies over open storage or process
areas, tents, air-supported structures, and grandstands. Users may also optionally complete the Fire Module
for confined building fires (Incident Types 113–118), although it is not required.
Like the other modules, the Structure Fire Module is divided into sections and further subdivided into
blocks. Only Block I1 must be completed for all structure fires. Completion of the remainder of the module is required only for building fires, although that portion of the module may also be completed for
non-building structure fires if desired.
SECTION I

This section collects information about the structure involved in the fire, including its type, current status,
height, and size.
I1

Structure Type P
Definition

The identification of a structure as a specific property type.

Purpose

Information on the structure type, combined with other structural characteristics, is useful for understanding fire behavior and provides assistance in targeting fire prevention or protection efforts.

Entry

Check or mark the box best indicating the type of structure involved in the fire. If the fire was in an enclosed building or a portable or mobile structure, complete the rest of the module.

The P denotes a required field.

Building Status P
Definition

The operational status of the building involved in the fire. This element indicates the actual use of the
building at the time of the fire.

Purpose

Building status, combined with other structural characteristics, is useful for understanding fire behavior,
the potential for loss of life and property, and the likely effectiveness of fire protection that existed before
the fire.

Entry

Check or mark the box best indicating the status of the building involved in the fire.

Example

A family of four occupied the house (2):

Building Height P
Definition

The number of stories at or above grade level and the number of stories below grade level in the fire building.

Purpose

Building height and depth below grade, combined with other structural characteristics, are useful for
pre-fire planning as well as for gaining a better understanding of fire behavior. Some fire departments use
building height and depth to determine life safety hazard values. The more difficult it is for people to escape, the higher the life safety hazard value for the building.

Entry

Enter the total number of stories at or above grade level and the total number of stories below grade level.
For split grades, consider the main egress point as the “at grade” portion of the building.
Do not count normally inaccessible attics, attics with less than standing height, or the roof as a story
(i.e., the roof is counted as part of the highest story).

The P denotes a required field.

Main Floor Size P
Definition

The size of the main floor in square feet. This is an estimate.

Purpose

Main floor size, combined with other structural characteristics, is useful for evaluating firefighting operations and the need to allocate resources based on size and complexity of structures. It also helps in understanding the potential life and property at risk.

Entry

Enter the total square footage of the main floor, or enter the area using length-by-width measurements (in
feet). Do not enter both.

CHAPTER 5 • STRUCTURE FIRE MODULE (NFIRS-3)
SECTION J

This section collects information on where in the structure the fire originated, how far the fire spread, and
the number of stories damaged by flame.
J1

Fire Origin P
Definition

Identifies the story where the fire originated within the building.

Purpose

The story of fire origin, combined with other structural characteristics, is helpful for gaining a better understanding of fire behavior and identifying any special problems in fire strategy and tactics. Information
on the frequency and nature of above- or below-grade-level fires is needed for assessing aerial apparatus
needs and performance. A fire in the upper levels of a high-rise building is often difficult to control because of delays in moving personnel and equipment to the fire floor.

Entry

Enter the story of fire origin. If below grade level, check or mark the Below Grade box.
Checking or marking the Below Grade box has the effect of entering a negative number in NFIRS 5.0.

Example

The fire began in the master bedroom on the second story:

Fire Spread P
Definition

The extent of fire spread in terms of how far the flame damage extended. The extent of flame damage is the
area actually burned or charred and does not include the area receiving only heat, smoke, or water damage.

Purpose

In combination with other information, this element describes the magnitude or seriousness of the fire. It
can be used to evaluate the effectiveness of built-in fire protection features or the effectiveness of the fire
suppression force relative to the conditions faced. The confinement and extinguishment of a fire is influenced by many factors. Fire spread indicates the combined effect of these conditions. Also, the analysis of
fire spread over many fires can reveal the effects of individual factors.
The P denotes a required field.

5-7

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 5 • STRUCTURE FIRE MODULE (NFIRS-3)

Entry

Check or mark the box best describing the extent of fire spread.
If the fire was confined to the object of origin, an entry should have been made in Block D3 of the Fire
Module. Do not check or mark any additional box in this block.
A room is a partitioned part of the inside of a building. If the flame damage extends beyond the area
of origin in a one-room building, such as a shed, the damage should be described as Confined to the
Building of Origin. The Confined to the Building of Origin box is also the appropriate description if the
fire was on the roof or outside wall of a building.

Example

A fire causes flame damage only in the room of origin (2):

Definition

The type of material contributing most to flame spread, if different from the Type of Material First Ignited
(Fire Module, Block D4). Skip this block if the material is unknown.
Type of material refers to the raw, common, or natural state in which the material exists. The type of material may be a gas, flammable liquid, chemical, plastic, wood, paper, fabric, or any number of other
materials.

Purpose

Knowing what type of material contributed most to flame spread is helpful in finding out why fires advance through a structure and understanding the rate at which fires develop. A study of this entry also aids
in assessing the need for standards on the flammability of materials. This information can also be helpful to
manufacturers for improving products.

The Civilian Fire Casualty Module should be completed whenever there are civilian casualties resulting
from a fire. A fire casualty is a person who is injured or killed as a result of a fire, including injuries or deaths
from natural or accidental causes sustained while involved in the activities of fire control, attempting
rescue, or escaping from the dangers of the fire. Fires include Incident Types 100–199 as recorded on the
Basic Module, Section C.
If a civilian injury is not directly related to fire, it may be reported on an EMS Module with the same
incident ID information.
A separate Civilian Fire Casualty Module is required for each fire casualty.
SECTION A

The guidance and directions for completing Section A of the Civilian Fire Casualty Module are the same
as for Section A in the Basic Module. It is stressed that the entries in Section A of the Civilian Fire Casualty Module must be identical with the entries on the corresponding Basic Module. If injuries occur in an
exposure fire, the casualty report should have the same entries as those from Section A of the Basic Module
for that exposure fire. An example of a completed Section A can be found on page 3–8.

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 8 • EMS MODULE (NFIRS-6)

CHAPTER 8 • EMS MODULE (NFIRS–6)

he EMS Module is an optional module. It should be used when that option has been chosen by your
State or local authorities.

This module is completed only if the fire department provides emergency medical service. If an inde-
pendent provider performs EMS, do not use this module.
The purpose of the EMS Module is to gather basic data as it relates to the provision of emergency medical
care to the community. It may be used by both responding EMS unit(s) and responding fire suppression
unit(s) that provide emergency medical services. This module does not include patient care information.
The data collected from this form are incident based not patient based.
The EMS Module is not intended to replace or otherwise interfere with State or local EMS patient care
reporting requirements. Instead, it is the intent that the data elements contained in this module be viewed
as “core elements” and be included in the design of upgrades or new EMS data collection systems.
The EMS Module may be completed when an Incident Type 100–243, 311, 321-323, 351–381, 400–431,
451, or 900 is reported in Section C of the Basic Module (NFIRS–1).
If the EMS is a fire casualty, completion of a separate Fire Service Casualty Module (NFIRS–5) is required.
SECTION A

The guidance and directions for completing Section A of the EMS Module are the same as for Section A in
the Basic Module. It is stressed that the entries in Section A of the EMS Module must be identical with the
entries on the corresponding Basic Module. An example of a completed Section A can be found on page
3–8.

If the casualty resulted from an exposure fire, enter the same exposure number that was entered in Section
A of the Basic Module for that exposure.

Delete/Change
Definition

Indicates a change to information submitted on a previous EMS Module or a deletion of all information
regarding that patient.

Purpose

To delete or change previously reported information.

Entry

Delete. Check or mark this box when you have previously submitted data on this EMS patient and now want
to have the data on this patient deleted from the database. If this box is marked, complete Section A, the
Patient Number originally assigned (Section B), and leave the rest of the report blank. Forward the report
according to your normally established procedures.
Change. Check or mark this box only if you previously submitted this fire incident to your State reporting
authority and now want to update or change the information in the State database. Complete Section A and
any other sections or blocks that need to be updated or corrected. If you need to blank a field that contains
data, you must resubmit the original module containing the newly blanked field along with all the other
original information in the module for that incident. This action is required only when sending an updated
module to your State reporting authority. Forward the report according to your normally established procedures.

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 8 • EMS MODULE (NFIRS-6)

Purpose

Fire departments can track the number of patients they treated at each EMS incident and identify how
many EMS Modules should be completed for the incident (one per patient).

Entry

Enter the total number of patients.
Complete a separate EMS Module for each patient treated.

Example

Two people were injured in a bicycle accident:

Patient Number P
Definition

A unique number is assigned to each patient treated at a single EMS incident.

Purpose

The patient number identifies each EMS patient separately in the EMS file. Data and other information concerning the patient can be accessed using this number in conjunction with other unique field information.

Entry

Enter the identification number assigned to this patient. A separate Patient Number is assigned to each EMS
patient. The first patient is always coded “001,” and each succeeding patient is numbered sequentially and
incremented by 1 beginning with “002.” The three-character numeric field is zero filled, not right justified.

Example

Three patients needed medical attention in the wrecked automobile; this report is for patient number two:

Date and Time Arrived at Patient and Time of Patient Transfer
Definitions

Time arrived at patient. The time when the fire department’s emergency personnel established direct contact
with the patient.
Time of patient transfer. The time when the response unit physically left the scene to transport the patient to an
emergency care facility or the time when the patient was transferred to another care provider.

Purpose

This information is needed to analyze time spent providing patient care on the scene of an incident. If
the Apparatus/Personnel Module (NFIRS–9/–10) is also used, then this element can document situations
when there is a significant delay between the time the response unit arrives on the scene and the time at
which personnel can access the patient.

Entry

For each incident, enter the dates (mm/dd/yyyy) and times of day (using the 24-hour clock) when
emergency personnel arrived at the patient and when the patient was transferred to another care provider.
Midnight is 0000 and signifies the start of a new day.
If the date(s) is the same as the Alarm date (Block E1, Basic Module), check the box(es) and enter only
the time of day.

Example

The fire department BLS unit arrived at the patient at 0105 on July 2, 2002. The patient was transferred to
the hospital 14 minutes later at 0199:

Body Site of Injury
Body Site of Injury was known as Part of Body Injured in NFIRS 4.1

Definition

The area of the body that sustained the injury. This field is designed to be used in conjunction with Injury
Type (Block H2).

Purpose

When combined with Injury Type and Cause of Injury, this entry provides useful data for EMS planners to
track patient’s injuries that required the use of the EMS system.

Entry

Enter up to five parts of the body where injuries occurred. List the body site with the most serious injury
first. If the patient is suffering from an illness and not an injury, skip to Block H3.

The P denotes a required field.

CHAPTER 9 • HAZMAT MODULE (NFIRS-7)

CHAPTER 9 • HAZARDOUS MATERIALS MODULE
(NFIRS–7)

he Hazardous Materials (HazMat) Module is an optional module. It should be used when that option
has been chosen by your State or local authorities.

The HazMat Module is used when the Other box in Block H3 (“Hazardous Materials Release”) of the Basic
Module (NFIRS–1) has been checked. Its purpose is to document reportable HazMat incidents. Generally
speaking, a reportable HazMat incident is when either:
1. Specialized HazMat resources were dispatched or used, or should have been dispatched
or used, for assessing, mitigating, or managing the situation.
OR
2. Releases or spills of hazardous materials that exceed 55 gallons occur.
Nothing in this definition is meant to alter compliance with State or local HazMat reporting requirements.
In States with mandatory reporting, the State reporting authority determines which optional modules
(EMS, HazMat, Wildland, etc.) are to be submitted to the State.
The HazMat Module permits hazardous materials incidents to be thoroughly profiled for incident management analysis and response strategy development. It collects relevant information on:
•
•
•
•
•

Hazardous materials identification.
Container information.
Release amounts and location.
Actions taken.
Mitigating factors.

In addition, aggregated data on hazardous materials incidents will provide invaluable information that
can be used by policymakers who develop regulations for the storage, use, and transportation of hazardous materials. It can also be used to develop recommended guidance for emergency personnel response to
HazMat incidents.
If more than one HazMat was involved, one form is completed for each HazMat released. (The term
release is intended to include spill.)
SECTION A

The guidance and directions for completing Section A of the HazMat Module are essentially the same as
for Section A in the Basic Module. One additional field is included in Section A of the HazMat Module (Haz
No.). It is stressed that the entries in Section A of the HazMat Module must be identical with the entries on
the corresponding Basic Module. An example of a completed Section A can be found on page 3–8.

for the identification of hazardous materials in international transportation. In some cases, a single UN
number will be assigned to several materials with similar properties. Not all hazardous materials have been
assigned a UN number.

Purpose

Aggregate information on the identities of hazardous materials being released can reveal trends or patterns
for particular materials or classes of materials. These trends may provide direction for policymakers, prevention efforts, and training curricula.

Entry

Enter the four-digit UN number assigned to the hazardous material. Leave the entry blank if a UN number
has not been assigned.
These numbers may be found in a variety of reference materials, including USFA’s Hazardous Materials Guide
for First Responders and the North American Emergency Response Guidebook (NAERG), published by the Research and
Special Programs Administration, U.S. Department of Transportation (DOT). A list of commonly encountered

DOT Hazard Classification

Definition

The Department of Transportation hazard classification describes the primary hazard associated with various categories of hazardous materials. The DOT hazard classification is intended for use on placards or
labels during the transportation of hazardous materials. Since many materials have multiple hazards, these
placards or labels may not describe all of the potential hazards faced by emergency responders at a HazMat
incident.

Equipment Involved in Release
Most of the Equipment Involved in Release codes were included in Equipment Involved in Ignition in NFIRS 4.1.
Equipment Type

Definition

The piece of equipment that either malfunctioned or, while working properly, allowed the release or
threatened release of hazardous materials.

Purpose

Analysis of the equipment involved in a HazMat release is useful for improving product safety and preventive
maintenance. It is just as important to know the kind of equipment that was used improperly as it is to know
the kind of equipment that malfunctioned. Misuse can be the direct result of the way the equipment is designed
and constructed. When involved in release, equipment information provides an important part of the causal data.
Equipment involved in release can be compared to other causal data to determine if the equipment was (or was
not) operating properly.

HazMat Civilian Casualties
Definition

The number of civilians injured or killed, either as a result of a HazMat incident or the action of handling
the HazMat incident. The term injury refers to physical damage to a person that requires either:
Treatment within 1 year of the incident by a practitioner of medicine,
OR
At least 1 day of restricted activity immediately following the incident. An injured person is a casualty.

Purpose

The collection of information on the number of persons injured or killed as a result of their contact or exposure to hazardous materials that have been spilled or released can provide a concise measure of the scope
of the human cost associated with hazardous materials incidents. This information can also be correlated
with container types, transport conditions, actions taken, and other data to help understand how to reduce
future HazMat injuries.

Entry

Identify and record separately the number of civilians injured and the number of civilians killed as a result
of a HazMat incident.
The optional EMS Module may be completed for all non-fire service persons injured or killed as a result
of their contact or exposure to hazardous materials. The Civilian Fire Casualty Module should not be
used for this purpose unless the release resulted in a fire and the civilians were injured as a result of
the fire. The Fire Service Casualty Module should be completed for all fire service personnel injured or
killed as a result of their contact or exposure to hazardous materials.
HazMat civilian casualties should not be entered in Block H1 of the Basic Module.

Example

One hundred civilians had varying degrees of nausea and dizziness as a result of the HazMat release:

CHAPTER 10 • WILDLAND FIRE MODULE (NFIRS-8)

CHAPTER 10
WILDLAND FIRE MODULE (NFIRS–8)

istorically, NFIRS data have not proven useful in understanding the nature and magnitude of the wildland fire problem. The optional Wildland Fire Module, in conjunction with the Basic Module and other optional modules, attempts to rectify this problem by capturing data about the number of acres burned,
the type of materials involved, the conditions that contributed to the ignition and spread of wildland fires,
and the resources needed to control or extinguish them.
The purpose of the Wildland Fire Module is to document reportable wildland fires:
Reportable Wildland Fire: Any fire involving vegetative fuels, including a prescribed fire, that occurs in the
wildland or urban-wildland interface areas, including those fires that threaten or consume structures.
Prescribed fires are included in this definition of reportable fires to better understand the role of fire in the
wildland ecosystem.
In accordance with your State or local policy, the Wildland Fire Module may be used in place of the Fire
Module (NFIRS–2) for the following Incident Type recorded on the Basic Module (Section C).
140 – Natural Vegetation Fire, Other.
141 – Forest, Woods, or Wildland Fire.
142 – Brush, or Brush-and-Grass Mixture Fire.
143 – Grass Fire.
160 – Special Outside Fire, Other.
170 – Cultivated Vegetation, Crop Fire, Other.
171 – Cultivated Grain or Crop Fire.
172 – Cultivated Orchard or Vineyard Fire.
173 – Cultivated Trees or Nursery Stock Fire.
561 – Unauthorized Burning.
631 – Authorized Controlled Burning.
632 – Prescribed Fire.
A prescribed fire that escapes management is a hostile fire (Incident Type 141). A hostile fire cannot
become a prescribed fire, but the management strategy (actions taken) may change.

Definitions

For the purpose of wildland fire reporting, the following definitions are used:
Prescribed Fire: Any fire ignited by management actions to meet specific objectives. A written, approved
prescribed fire plan must exist prior to ignition.

The P denotes a required field.

Urban-Wildland Interface Fire: Any fire, other than a prescribed fire, where fire suppression tactics were influenced by a geographical area where structures and other human development meets or intermingles
with wildland or vegetative fuels.
Wildland Fire: Any fire involving vegetative fuels, other than a prescribed fire, that occurs in the wildland.
A wildland fire may expose and possibly consume structures (Incident Type 141).
Wildland: An area where development is essentially nonexistent, except for roads, railroads, power lines,
and similar facilities.
The Wildland Fire Module permits wildland fires to be profiled in detail for resource allocation, incident

Fire Suppression Factors
Definition

Factors that contributed to the growth, spread, or suppression of the fire. This is used to report incident
information that directly impacted the ignition, spread of fire, incident complexity, or presence of hazardous conditions.

Purpose

Fire suppression factors provide essential guides for planning strategic and tactical procedures for future
incidents, as well as for identifying fire training and equipment needs.

Entry

Enter the three-digit code and description for up to three fire suppression factors or conditions that constituted a significant fire suppression problem or affected how the fire was managed. If no factors were
involved in the fire suppression effort, check or mark the None box.

Example

A large brush fire was burning on a military installation (462) in an area where unexploded munitions
(327) could be encountered. The incident commander decided the best course of action was to allow the
fire to burn but to establish a control line outside the perimeter of the installation:

Equipment Involved in Ignition
Definition

The piece of equipment that provided the principal heat source to cause the ignition if the equipment malfunctioned or was used improperly.

Purpose

Analysis of the equipment involved in ignition is useful for improving product safety and preventive maintenance. It is just as important to know the kind of equipment that was used improperly as it is to know
the kind of equipment that malfunctioned. Misuse can be the direct result of the way the equipment is
designed and constructed. When involved in ignition, equipment information provides an important part
of the causal data. Equipment involved in ignition can be compared to other casual data to determine if the
equipment was (or was not) operating properly.

Entry

Enter the three-digit code and description that best describes the equipment involved in ignition. If no
equipment was involved in ignition, check or mark the None box.

Definition

Space is provided to record the six-character identification number for the National Fire Danger Rating
System (NFDRS) Weather Station that monitors weather conditions at the location of fire origin.

Purpose

Researchers can obtain specific weather data for the time and location of the fire origin. Specific weather
data permits analysis of those conditions that may have contributed to the fire cause or spread.

Entry

Enter the six-digit NFDRS Weather Station ID number. See the completed example at the end of Section H.
If the descriptive weather information is not provided, it will be necessary for the local fire department
to access the NFDRS database to perform later analysis of wildland fires using weather data. Because this
may not always be feasible, fire departments should always complete this section themselves whenever
possible.

measured using an anemometer. Calm conditions are recorded as “0.” See the completed example at the
end of Section H.
Temperature and Relative Humidity

Definitions

Air temperature is measured in degrees Fahrenheit at the location of the fire origin when the fire started.
Relative humidity is the ratio expressed as a percent of the amount of water vapor to the greatest amount
possible at the same temperature.

Purpose

Temperature and humidity information is used to access the potential for ignition in various weather
conditions and to understand problems associated with suppressing fires in different ambient temperatures
and humidity levels.

Entries

Enter the actual or estimated air temperature in degrees Fahrenheit at the time the incident started. If the
temperature is below zero, check or mark the box that indicates a negative temperature.
Enter the percent humidity at the time the incident started. See the completed example at the end of Section H.
Fuel Moisture

Definition

The 10-hour reading of the moisture content of a fuel stick taken in the general area of fire origin. Fuel
moisture is expressed as a percentage of the weight (generally ranging from 0 to 25 percent).

Purpose

Information about fuel moisture is used in fire modeling to assess the potential for ignition and rate of
spread for different fuels under various weather conditions.

Entry

Enter the fuel moisture percentage level. See the completed example at the end of Section H.
Fire Danger Rating

Definition

Fire danger rating refers to one method of describing the wildfire threat in a particular area, based on the
NFDRS. It is derived from both constant and variable fire danger factors that affect the ignition, spread, and
difficulty of control of fires and the damage they cause. Factors considered when estimating the fire danger
are temperature, relative humidity, wind speed, fuel type, and fuel moisture.

Purpose

This information is used in fire prevention activities to determine when fires are most likely to occur and
their severity. Burning bans and park or forest closures or restrictions may be invoked based on the fire
danger rating. It is also useful in pre-suppression planning to determine staffing levels and critical initial
attack times.

CHAPTER 10 • WILDLAND FIRE MODULE (NFIRS-8)

Purpose

This information provides important information to resource planners and policymakers developing zoning ordinances and regulations regarding wildland and rural areas. This information may also help direct
future training and incident management efforts.

Entry

Enter the number of buildings ignited by the wildland fire. If no buildings were ignited, check or mark the
None box.
A separate exposure report should be filled out for each building ignited.

Example

One building was ignited in a wildland fire:

ignited in Wildland fire

Number of Buildings Threatened
Definition

The number of buildings, if any, that were threatened, but not ignited by the wildland fire. This field implies that these buildings were “saved” by the efforts of fire suppression resources.
This field is completed only when the fire management tactics employed were for the specific purpose
of protecting threatened structures.

Purpose

The number of buildings threatened provides important information to resource planners and policymakers
developing zoning ordinances and regulations regarding wildland and rural areas. This information may also
help direct future training and incident management efforts.

Entry

Enter the number of buildings threatened but not ignited by the wildland fire. Check or mark the None
box if no buildings were threatened.

Example

Two farm buildings were threatened in the wildland fire:

I3

Total Acres Burned P
Definition

This data element captures the total acres burned by a wildland fire.

Purpose

Recording the estimated number of acres burned indicates the magnitude of each fire and of the wildland
fire problem overall. This can be used to evaluate progress in wildland fire prevention. This information
can also help determine the magnitude of resources that should be devoted to fire protection and the cost
effectiveness of various programs. An estimate of the number of acres burned represents a vital component
of the overall fire loss picture.

Entry

Enter the total number of acres burned. If less than one acre was burned, the decimal point field should be
used to denote tenths of an acre.
This entry should be the most accurate estimate of acres burned that is practical to obtain (one acre
equals 43,560 square feet). Estimates based on the use of accurately scaled maps, dot grids, planimeters, or other accurate measuring methods are preferred.

Example

A fire destroys 1,671 acres:

Primary Crops Burned
Definition

This data element identifies up to three types of crops that burned.

Purpose

Information about what type of crops burned is useful as a measure of loss and in tracking trends and patterns in wildland fires as well as planning prevention strategies.

Entry

Enter up to three primary crops that burned in the fire. Enter the crop with the most burned acres first. If
no crops were burned, leave this block blank.

The P denotes a required field.

SECTION J

Property Management
Definition

The name of the principle entity having responsibility for the maintenance or control of the property
where the fire originated. It also allows for the reporting of the percent of the total acres burned for each
type of ownership involved.

Purpose

The number of acres burned by property ownership is of significant value to local fire departments as well
as to State and Federal wildland agencies. It provides a means to determine the frequency and impact of
fire on property managers, especially major holders of land, such as ranchers, lumber and paper companies, agricultural producers, and Federal and State governments. This information also can help target fire
protection programs at entities having the greatest risk or loss potential.

Entry

Indicate the percent of the total acres burned for each type of ownership involved, then check or mark the
box that best describes the principle entity responsible for the property where the fire originated. If responsibility cannot be determined or is unknown, check or mark the Undetermined box.
Check or mark only one owner/management entity.
If the Federal (6) box was checked or marked, enter the Federal Agency Code.

The P denotes a required field.

CHAPTER 10 • WILDLAND FIRE MODULE (NFIRS-8)

Example

The fire started on a privately owned and operated farm (private tax paying) (1) and spread to Montana’s
Big Horn Canyon (Federal Agency Code MTBIP). Thirty percent of the total acres burned was on the farm
and 70 percent was owned by the Federal government:

Property Management
Indicate the percent of the total acres burned for each ownership type then check the ONE box to identify the property ownership at the origin of the fire. If the ownership at origin is Federal,
enter the Federal Agency Code.

NFDRS Fuel Model at Origin
Definition

This data element identifies the type of wildland fuel involved in a wildland fire at the point of origin. The
Fuel Model is a simulated fuel complex or description of various vegetative fuels and combinations of vegetative fuels. Fuel models were devised as a means of organizing information about vegetative fuels for use
in the National Fire Danger Rating System (NFDRS) to predict fire danger. The local forester should be able
to assist in identifying the fuel models in your area.

Purpose

Fuel models were devised as a means for organizing the required wildland fuels information that is used in
the NFDRS to predict the behavior of a potential wildfire.

Entry

Enter the two-digit NFDRS Fuel Model code and description that best identifies the type of wildland
vegetation burned at the point of origin.

Example

The fire area consisted of mostly mature brush (02):NFDRS FUEL MODEL AT ORIGIN CODES

NFDRS Fuel Model at Origin

Enter the code and the descriptor corresponding
to the NFDRS Fuel Model at Origin

0 2

Mature brush

NFDRS FUEL MODEL AT ORIGIN CODES
01

Fuel Model A—Annual grasses. This fuel model represents grasslands vegetated by annual grasses and forbs. Brush
or trees may be present but are very sparse, occupying less than one-third of the area. Examples of types where
Fuel Model A should be used are cheatgrass and medusahead. Open pinyon-juniper, sagebrush-grass, and desert
shrub association may appropriately be assigned this fuel model if the woody plants meet the density criteria.
The quantity and continuity of the ground fuels vary greatly with rainfall from year-to-year.

Fuel Model B—Mature brush (6 feet or higher). Mature, dense fields of brush 6 feet (2 m) or more in height are
represented by this fuel model. One-fourth or more of the aerial fuel in such stands is dead. Foliage burns readily.
Model B fuels are potentially very dangerous, fostering intense, fast-spreading fires. This model is for California
mixed chaparral generally 30 years or older. The B model is more appropriate for pure chamise stands. The B
model may also be used for the New Jersey pine barrens.

The P denotes a required field.

10-50

NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 10 • WILDLAND FIRE MODULE (NFIRS-8)
03

Fuel Model C—Open pine with grass. Open pine stands typify Model C fuels. Perennial grasses and forbs are the
primary ground fuel, but there is enough needle litter and branchwood present to contribute significantly to the
fuel loading. Some brush and shrubs may be present, but they are of little consequence. Situations covered by
Fuel Model C are open, longleaf, slash, ponderosa, jeffrey, and sugar pine stands. Some pinyon-juniper stands may
qualify.

Fuel Model D—Southern rough. This fuel model is specifically for the palmetto-gallberry understory–pine overstory association of the southeast coastal plains. It can also be used for the so-called “low pocosins” where Fuel
Model O might be too severe. This model should only be used in the Southeast because of a high moisture of
extinction.

Fuel Model E—Hardwood litter (fall). Use this model after leaf fall for hardwood and mixed hardwood–conifer
types where the hardwoods dominate. The fuel is primarily hardwood leaf litter. The oak–hickory types are best
represented by Fuel Model E, but E is an acceptable choice for northern hardwoods and mixed forests of the
Southeast. In high winds, the fire danger may be underrated because rolling and blowing leaves are not taken into
account. In the summer after the trees have leafed out, Fuel Model E should be replaced by Fuel Model R.

Fuel Model F—Intermountain West brush. Model F represents mature closed chamise stands and oakbrush fields
of Arizona, Utah, and Colorado. It also applies to young, closed stands and mature, open stands of California
mixed chaparral. Open stands of pinyon-juniper are represented; however, fire activity will be overrated when
windspeeds are low and where ground fuels are sparse.

Fuel Model G—West Coast conifers; close, heavy down materials. Fuel Model G is used for dense conifer stands
where there is a heavy accumulation of litter and downed woody material. Such stands are typically overmature
and may also be suffering insect, disease, wind, or ice damage—natural events that create a very heavy buildup
of dead material on the forest floor. The duff and litter are deep, and much of the woody material is more than 3
in (7.5 cm) in diameter. The undergrowth is variable, but shrubs are usually restricted to openings. Types meant
to be represented by Fuel Model G are hemlock–Sitka spruce, coast douglas fir, and wind-thrown or bug-killed
stands of lodgepole pine and spruce.

Fuel Model H—Short-needle conifers; normal down woody materials. The short-needled conifers (white pines,
spruces, larches, and firs) are represented by Fuel Model H. In contrast to Model G fuels, Fuel Model H describes
a healthy stand with sparse undergrowth and a thin layer of ground fuels. Fires in H fuels are typically slow
spreading and are dangerous only in scattered areas where the downed woody material is concentrated.

Fuel Model I— Heavy slash, clear-cut conifers greater than 25 tons per acre. Fuel Model I was designed for
clearcut conifer slash where the total loading of materials less than 6 in (15 cm) in diameter exceeds 25 tons per
acre. After settling and the fines (needles and twigs) fall from the branches, Fuel Model I will overrate the fire
potential. For lighter loadings of clearcut conifer slash, Fuel Model J should be used, and for light thinnings and
partial cuts where the slash is scattered under a residual overstory, Fuel Model K should be used.

Fuel Model J—Medium slash, heavily thinned conifers (less than 25 tons per acre). This model complements
Fuel Model I. It is for clearcuts and heavily thinned conifer stands where the total loading of materials less than 6
in (15 cm) in diameter is less than 25 tons per acre. Again, as the slash ages, the fire potential will be overrated.

Fuel Model K—Light slash (less than 15 tons per acre). Slash fuels from light thinnings and partial cuts in conifer
stands are represented by Fuel Model K. Typically, the slash is scattered about under an open overstory. This model
applies to hardwood slash and to southern pine clearcuts where the loading of all fuels is less than 15 tons per
acre.

Fuel Model L—Perennial grasses. This fuel model is meant to represent grasslands vegetated by perennial grasses.
The principal species are coarser and the loading heavier than those in Model A fuels. Otherwise the situations
are very similar; shrubs and trees occupy less than one-third of the area. The quantity of fuel in these areas is
more stable from year-to-year. In sagebrush areas, Fuel Model T may be more appropriate.

Fuel Model N—Sawgrass, marsh needle-like grass. This fuel model was constructed specifically for the
sawgrass prairies of south Florida. It may be useful in other marsh situations where the fuel is coarse
and reedlike. The model assumes that one-third of the aerial portion of the plants is dead. Fast-spreading,
intense fires can occur even over standing water.

Fuel Model O—High pocosin. Fuel Model O applies to dense, brushlike fuels of the Southeast. O fuels, except for a
deep litter layer, are almost entirely living, in contrast to B fuels. The foliage burns readily except during the active
growing season. The plants are typically over 6 ft (2 m) tall and are often found under an open stand of pine. The
high pocosins of the Virginia, North Carolina, and South Carolina coasts are the ideal of Fuel Model O. If the plants
do not meet the 6-ft (2-m) criteria in those areas, Fuel Model D should be used.

Fuel Model P—Southern long-needle pine. Closed, thrifty stands of long-needled southern pines are characteristic of P fuels. A 2- to 4-in (5- to 10-cm) layer of lightly compacted needle litter is the primary fuel. Some smalldiameter branchwood is present, but the density of the canopy precludes more than a scattering of shrubs and
grass. Fuel Model P has the high moisture of extinction characteristic of the Southeast. The corresponding model
for other long-needled pines is U.

Fuel Model Q—Alaska black spruce. Upland Alaskan black spruce is represented by Fuel Model Q. The stands are
dense but have frequent openings filled with usually flammable shrub species. The forest floor is a deep layer of
moss and lichens, but there is some needle litter and small-diameter branchwood. The branches persist on the trees,
and ground fires easily reach into the tree crowns. This fuel model may be useful for jack pine stands in the Lake
States. Ground fires are typically slow spreading, but a dangerous crowning potential exists.

Fuel Model R—Hardwood litter (summer). This fuel model represents the hardwood areas after the canopies leaf
out in the spring. It is provided as the off-season substitute for Fuel Model F. It should be used during the summer
in all hardwood and mixed conifer–hardwood stands where more than half of the overstory is deciduous.

Fuel Model S—Tundra. Alaskan or alpine tundra on relatively well-drained sites is the S fuel. Grass and low shrubs
are often present, but the principal fuel is a deep layer of lichens and moss. Fires in these fuels are not fast spreading or intense, but are difficult to extinguish.

Fuel Model T—Sagebrush with grass. The bothersome sagebrush-grass types of the Great Basin and the Intermountain West are characteristic of T fuels. The shrubs burn easily and are not dense enough to shade out grass and
other herbaceous plants. The shrubs must occupy at least one-third of the site, or the A or L fuel models should be
used. Fuel Model I might be used for immature scrub oak and desert shrub associations in the West and the scrub
oak–wire grass type in the Southeast.

Fuel Model U—Western long-needled pine. Closed stands of western long-needled pines are covered by this
model. The ground fuels are primarily litter and small branchwood. Grass and shrubs are precluded by the dense
canopy, but occur in the occasional natural opening. Fuel Model U should be used for ponderosa, Jeffrey, sugar, and
red pine stands of the Lake States. Fuel Model P is the corresponding model for southern pine plantations.

Undetermined.

such information, fire service and law enforcement agencies can develop and implement arson prevention
initiatives that will allow them to use their resources in the most efficient and effective manner. The NFIRS
5.0 Arson Module (NFIRS–11) was developed with this goal in mind.
Arson: To unlawfully and intentionally damage, or attempt to damage, any real or personal property by
fire or incendiary device.
This optional Arson Module may be used whenever the Cause of Ignition (Fire Module, Block E1) is coded
as Intentional or as Cause Under Investigation without any distinction made as to whether a crime has
occurred or a determination of criminal intent. The Arson Module may also be used when the fire is coded
as Cause Undetermined After Investigation.
The Arson Module may also be used to document juvenile-set fires, whether determined to be intentional,
unintentional, or under investigation. This information will permit analysis of juvenile firesetting trends,
including intervention strategies and recidivism.
Juvenile-set fires are defined to be those fires where the person involved in the ignition is under the age
of 18.
The Arson Module consists of two parts: a local investigation module that permits a fire department or
arson investigation unit to document certain details concerning the incident; and a juvenile firesetter section that identifies key items of information that could be used for local, State, and national intervention
programs.
Many arson investigation units use an arson information management system to collect and compile information on arson incidents. This module is not intended to replace such systems; instead, it identifies those
data elements that could be exported to NFIRS and included as an integral part of the U.S. Fire Administration National Fire Database and the Bureau of Alcohol, Tobacco and Firearms (BATF), Arson and Explosives
National Repository.
SECTION A

The guidance and directions for completing Section A of the Arson Module are the same as for Section A in
the Basic Module. It is stressed that the entries in Section A of the Arson Module must be identical with the
entries on the corresponding Basic Module. An example of a completed Section A can be found on page
3–8.

enforcement agency that has jurisdiction for a criminal investigation or another fire department that may
have been requested to conduct the investigation.

Purpose

This element provides the details necessary to contact the agency that conducted any follow-up of the
incident. It also allows for the collection, compilation, and analysis of all data associated with a specific
incident.

Entry

Enter the referred agency’s name, telephone number, address, case number, Originating Agency Identifier
(ORI) number, Federal Identifier (FID) code, and FDID (if applicable). Check or mark the None box if the
case was not referred to another agency.
ORI: A unique identification number assigned to law enforcement agencies (towns, cities, counties, State
police agencies, and some colleges and universities) participating in the FBI’s Uniform Crime Reporting
(UCR) system or the National Incident-Based Reporting System (NIBRS).
FID: A two-character identification number used by Federal departments to submit crime data to UCR/
NIBRS gathered by its dependent bureau/agencies.
Collectively, the ORI, FID, and Incident numbers provide the necessary uniqueness to avoid duplication of
reported incidents.
“00” is used for State and local agencies as the FID codes. Federal departments such as the FBI use an
assigned FID code. This list is not provided in this guide.
Also enter the complete address of the agency the incident was referred to for follow-up investigation.

juvenile offenders are handled and is particularly useful in tracking juvenile firesetter trends. At the local
level, this field is also useful in determining where repeat offenders have been sent in the past.

Entry

Check or mark the box that best describes the disposition of the subject.

Example

The fire department released the subject to social services (3):

SECTION E

Supplemental Special Studies
Definition

These fields should be used when you are using the paper forms and need space for more than one special
study.
Temporary data elements that can be used for collection of information that is of special interest for a
defined period. Special studies are typically required to capture information on emerging trends, problem
areas, or a specific issue being studied. When the answer becomes known through the special study, the
collection of that field is no longer required. If the data will always be needed for permanent collection, a
State- or department-defined permanent user field should be created and used instead of the Special Studies field. A State, a fire department, or the NFDC can define special studies.
Special Study ID Number: This number uniquely identifies each special study that is being run by the fire
department, State, or NFDC
Special Study Value: The value in the field being collected. Responses for special studies can be defined as
codes or as alphanumeric entries of numeric values or dates. States, fire departments, and the NFDC can
define Special Studies fields.

Purpose

The use of special studies allows departments, States, and the NFDC to quickly collect information on an
issue or problem and answer a specific question through the temporary use of a special study field over a
defined period of time. This is a State or local option.

Entry

Remarks
This supplemental Remarks block is an additional area for comments concerning the incident if you run

AND ABBREVIATIONS

NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY

Appendix C
Glossary of Terms and Abbreviations
Terms
The terminology used in this document provides a common language for recording fire service data. The
following terms are used as defined and discussed below.
Alarm. Any notification made to the fire department that a situation exists or may exist that requires a
response.
Area of Origin. The use of the room or area within the property where the fire originated.
Automatic. As applied to fire protection devices, a device or system providing an emergency function
without the necessity of human intervention.
Backfire. A fire set along the inner edge of a fire control line to consume the fuel in the path of a
wildland fire or change the direction of force of the fire’s convection column. Doing this on a
small scale and with closer control, in order to consume patches of unburned fuel and aid control line construction, is known as “burning out.”
Building. A structure enclosed with walls and a roof and having a defined height.
Building Fire. See Structure Fire.
Burning. The process of self-perpetuating combustion, with or without an open flame. Smoldering
is burning.
Casualty (Fire). A person who is injured or killed at the scene of a fire. (Includes injuries or deaths
from natural or accidental causes sustained while involved in the activities of fire control, rescue
attempt, or escaping from the dangers of the fire.)
Census Data. Demographic population data available by statistical areas from a governmental agency.
Civilian Fire Casualty. Any non-fire service casualty who is injured or killed at the scene of a fire.
Char. Material that has been partially burned on the exterior of the object and has a blackened carbonized appearance.
Combustible. A material or structure that will release heat energy on burning.
Combustible Liquid. Any liquid having a flash point at or above 100°F (37.8°C) (closed cup).

The P denotes a required field.

C-2

NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY
Confine a Fire. To restrict the fire within determined boundaries established either prior to the fire
or during the fire. Wildland suppression action may be minimal and limited to surveillance under appropriate conditions.
Contain a Fire. To take suppression action as needed that can reasonably be expected to check the
fire’s spread under prevailing conditions.
Emergency Scene. The area encompassed by the incident and the surrounding area needed by the
emergency forces to stage apparatus and mitigate the incident.
EMT–Basic. Technician has the knowledge and skills of the first responder, but is also qualified to
function as minimum staff for an ambulance (see Table of Care). For example, at the scene of a
cardiac arrest, the EMT–Basic would be expected to defibrillate and ventilate the patient with a
manually operated device and supplemental oxygen.
EMT–Intermediate. Technician has the knowledge and skills of the preceding levels, but also can
perform essential advanced techniques and administer a limited number of medications (see
Table of Care). For example, at the scene of a cardiac arrest, the EMT–Intermediate would be
expected to intubate and administer first-line ACLS medications.
EMT–Paramedic. Technician has demonstrated the competencies expected of an EMT–Intermediate
provider, but also can administer additional interventions and medications (see Table of Care).
For example, at the scene of a cardiac arrest, the EMT–Paramedic might administer second-line
ACLS medications and use an external pacemaker.
Explosion. Violent bursting caused by either a combustion process or an overpressure condition.
Typical combustion processes include ignition and burning of combustible gas, dust, or flammable vapor mixture. These are technically “fires.” Typical overpressure conditions include steam
pressure, chemical reactions, and compressed gas container rupture. These are technically not
“fires.”
Exposure Fire. A fire in a building, structure, vehicle, or outside property resulting from a fire
outside that building, structure, vehicle, or outside property.
Exposure (Human). Potential for injury or death to humans.
Fatality. An injury that is fatal or becomes fatal within 1 year of the incident.
Fire. Any instance of destructive and uncontrolled burning, including explosion, of combustible
solids, liquids, or gases. Fire does not include the following, except where they cause fire or
occur as a consequence of fire:
• Lightning or electrical discharge.
• Rupture of a steam boiler, hot water tank, or other pressure vessel due to internal pressure and
not to internal combustion.
• Explosion of munitions or other detonating material.
The P denotes a required field.

NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY
• Accident involving ship, aircraft, or other vehicle.
• Overheat condition.
Fire Area (Structure). The space within a structure bounded by fire division assemblies
(2-hour fire rating or greater).
Fire Area (Wildland). The area within wildfire perimeter control lines.
Fire Blackout. That point in time when there is no longer any evidence of open flame or glow of
burned material.
Fire Contained. That point in time when fire spread is stopped, but the fire is not necessarily under
control.
Fire Control Line. Comprehensive term for all constructed or natural barriers and treated fire edges
used to control a fire.
Fire Damage. The total damage to a building, structure, vehicle, natural vegetation cover, or outside
property resulting from a fire and the act of controlling that fire. Included are smoke, water,
backfires, firebreaks, and fire control damage.
Fire Extinguished. That point in time when there is no longer any abnormal heat or smoke being
generated in material that was previously burning.
Fire Ground. See Emergency Scene.
Fire Service Personnel. All employees, whether career or volunteer, of a fire department who are
assigned or may be assigned to perform duties at emergency incidents.
Fire Under Control. (1) That point in time when a fire is sufficiently surrounded and quenched so
that in the judgment of the commanding officer it no longer threatens destruction of additional
property. (2) In wildfire, that point in time when a control line is around a fire, any spot fires
therefrom, and any interior islands to be saved. Any unburned area adjacent to the fire side of the
control lines are burned out, and all hot spots that are immediate threats to the control line are
cooled down, until the lines can reasonably be expected to hold under foreseeable conditions.
First Responder. Uses a limited amount of equipment with various knowledge and skill in each of
the core elements (see EMS levels above). For example, at the scene of a cardiac arrest, the first
responder would be expected to notify EMS (if not already notified) and initiate CPR with an
oral airway and a barrier device.
Fixed Object. An object, device, or appliance that is fastened or secured at a specific location (e.g., a
steam radiator).
Flames. Products of combustion that are illuminated by the heat of combustion and accompany the
burning of most materials in normal atmospheres.
The P denotes a required field.

APPENDIX C• GLOSSARY
Flammable Liquid. Any liquid having a flash point below 100°F (37.8°C) (closed cup) and having a
vapor pressure not exceeding 40 psia (2068 mm Hg) at 100°F (37.8°C).
Gas. A material that has a vapor pressure exceeding 40 psia (2068.6 mm) at 100°F (37.8°C). (Gasoline is a liquid, not a gas.)
General Property Use. The actual general (overall) use of land or space under the same management or ownership or within the same legal boundaries, including any structures, vehicles, or
other appurtenances thereon.
Grade. Reference plane representing the elevation of finished ground level adjoining the building at
the main entrance.
Hazardous Material. Any material that is an air-reactive material, flammable or combustible liquid, flammable gas, corrosive material, explosive material, organic peroxide, oxidizing material,
radioactive material, toxic material, unstable material, or water-reactive material; and any substance or mixture of substances that is an irritant or a strong sensitizer or that generates pressure
through exposure to heat, decomposition, or other means.
Heat of Ignition. The heat energy that brings about ignition. Heat energy comes in various forms
and usually from a specific object or source. Therefore, the heat of ignition is divided into two
parts: “equipment involved in ignition” and “form of heat of ignition.”
Ignition. The physical and chemical processes involved in reaching a point of self-perpetuation of
fire whether or not there is an open flame.
Ignition Factor. The condition or situation that allowed a heat source and a combustible material to
combine to initiate a fire.
Incident. An event to which the reporting agency responds or should have responded. Included are
“walk-ins” treated at the station. An incident may have more than one response. A rekindle is a
separate incident.
Incident Record. The official file on an incident.
Incident Report. A document prepared by fire department personnel about a particular incident.
For understanding and legal purposes, this report should be in their own words. For summarization purposes, the information on this report can be classified into broad categories. The incident
report is always part of the incident record or file.
Injury. Physical damage to a person suffered as the result of an incident that requires (or should
require) treatment by a practitioner of medicine, a registered EMT, or a paramedic within 1 year
of the incident (regardless of whether treatment was actually received) or that results in at least 1
day of restricted activity immediately following the incident.

Occupied. An area with persons present. A hotel (general property use) could be occupied, but the
restaurant (specific property use) not occupied; likewise, the restaurant could be occupied, but
its storeroom (area of origin) not occupied.
Overhaul. The act of making a fire scene safe after it is controlled, such as extinguishing or removing
burned material, checking inside walls and hidden spaces, etc. For wildland fires, see Mop-Up.
Overheat. Destruction of material by heat without self-sustained combustion. Removal of the heat
source will stop the destruction. Overheat is the stage before ignition.
Overpressure. A transient air pressure, such as the shock wave from an explosion, that is greater than
the surrounding atmospheric pressure.
Portable. An object, device, or appliance that can normally be moved by one person, is designed to
be used in multiple locations, and requires no tools to install.
The P denotes a required field.

NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY
Prescribed Fire. Any fire ignited by management actions to meet specific objectives. A written,
approved prescribed fire plan must exist prior to ignition. The controlled application of fire
to wildland fuels in either their natural or their modified state under specified environmental
conditions that allow the fire to be confined to a predetermined area and, at the same time, to
produce the intensity of heat and rate of spread required to attain planned resource management
objectives.
Principal Meridian. There are 45 principal meridians defined in the United States. They are identified at the end of this appendix.
Property. A thing of value. Specific (fixed) property refers to those things that make up the Earth’s
surface (e.g., water, land, roadways, structures, buildings). Mobile property refers to those things
that normally move in relation to the Earth’s surface (e.g., ships, airplanes, trains, trucks, automobiles).
Property Inventory. Information known about a property before an emergency occurs. This knowledge is in two parts: that which is general in character and has to do with external features (such
as location, water supply, and construction), and that which is specific in character relating to
internal features (such as interior finish, vertical openings, or suppression systems).
Property Use. The use to which a property is put. A building, for example, could serve as a garage
or a hospital or a department store. The use of property does not define any of the other important fire-related details of a property such as access, ownership, size, internal weaknesses in fire
defense, or construction.
Public Land Survey System. The Land Ordinance of 1785 established the Public Land Survey System in the United States. The surveys cover 30 States; other survey systems are used by the founding 13 States, Kentucky, Tennessee, Maine, Vermont, West Virginia, Texas, and Hawaii.
Range. Ranges are numbered east and west of the principal meridian. The first three digits are the
range number and the fourth digit indicates a full or partial range (0 = full, 1 = 1/4, 2 = 1/2,
and 3 = 3/4). The fifth character (E or W) indicates direction from the principal meridian.
Rekindle. The redevelopment of a fire after it was thought to have been extinguished by the original
fire service response. Fire service response to a rekindle should be treated as a separate incident.
Reportable Fire. Any unfriendly, hostile fire that comes to the attention of an agency keeping fire
records. Included are fires that may be discovered in progress or discovered after extinguishment.
Response. The deployment of an emergency service resource to an incident.
Room. The space or area bounded by walls. The walls may be fire rated and impede fire spread or not
fire rated (e.g., mesh screen), which may impede exiting of personnel.

The P denotes a required field.

C-7

NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY
Scorch. Discoloring (browning or blackening) of a material, a characteristic of the overheat condition. Removal of the heat source will stop the destruction.
Section. Sections are numbered 1–36 beginning in the northeast corner for all but the very earliest
principal meridians. Sections 1–6 are the northern most tier and are numbered east to west. Sections 7–12 are the next tier south of the first tier and are numbered west to east. The remaining
sections follow the same pattern. Each section is nominally 640 acres, although some sections
vary from the standard.
Smoldering. Self-sustaining combustion of a material without any flame evident.
Stationary Object. Any object, device, or appliance that is not fastened but that is not readily moved
from one place to another in normal use (e.g., a refrigerator).
Story. That portion of a building between the upper surface of any floor and the upper surface of the
floor next above, except that the topmost story is that portion of a building between the upper
surface of the topmost floor and the upper surface of the roof deck above.
Structure. An assembly of materials forming a construction for occupancy or use to serve a specific
purpose. This includes, but is not limited to, buildings, open platforms, bridges, roof assemblies
over open storage or process areas, tents, air-supported structures, and grandstands.
Structure Fire. Any fire inside a structure whether it involves the structure or not, or any fire under
or touching a structure that involves the structure.
Subsection. Sections can be subdivided into successive quarters and described as the NE quarter,
NW quarter, SE quarter, and SW quarter (each approximately 160 acres). Each quarter can be
quartered again to describe 40-acre parcels. For example, the SE/4 of the NW/4 would be the
40-acre parcel NW of the section center (read small parcel to large parcel).
Toxic Material. Any material that may constitute a hazard to life or health, either temporary or permanent, from exposure by contact, inhalation, or ingestion.
Township. Townships are numbered north and south of the principal base line. The first three digits
are the township number, and the fourth digit indicates a full or partial township (0 = full, 1 =
1/4, 2 = 1/2, and 3 = 3/4). The fifth character (N or S) indicates direction from the baseline.
Urban–Wildland Interface Area. The geographical area where structures and other human development meet or intermingle with wildland or vegetative fuels.
Urban–Wildland Interface Fire. Any fire, other than prescribed fire, where fire suppression tactics
were influenced by a geographical area where structures and other human development meet or
intermingle with wildland or vegetative fuels (Incident Type 632).
Vacant. No furnishings or equipment are present.
The P denotes a required field.

C-8

NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY
Wildland Fire. Any fire involving vegetative fuels, other than prescribed fire, that occurs in the wildland. A wildland fire may expose and possibly consume structures (Incident Type 141).
Wildland. Land in an uncultivated, more or less natural state and covered by timber, woodland,
brush, or grass. An area in which development is essentially nonexistent except for roads, railroads, power lines, and similar facilities.
