FOREWORD

In 1986 the National Wildfire Coordinating Group (NWCG) authorized the Fire Equipment

Working Team (FEWT) to establish a subcommittee to improve and update the Spark

Arrester Guide (SAG). The subcommittee reduced the size of the previous SAG and

redesigned it to improve its effectiveness and expand its applicability to more wildland

fire agencies and geographic regions. The SAG is published for the guidance of

cooperating Federal, State, and local agencies. Federal and State laws and administrative

requirements prescribe when and where spark arresters are required.

Appropriate Standards referenced in this SAG establish the minimum performance and

maintenance requirements of spark arresters for internal combustion engines to be

operated on or near grass, timber, brush, or other wildland fuels. During periods of very

high or extreme fire danger, spark arresters meeting these Standards will not give

complete protection against exhaust spark fires. Additional measures, including shutdown

of operations, may be required during such periods.

The U.S. Department of Agriculture maintains a spark arrester test facility at the Forest

Service, San Dimas Technology and Development Center, 444 East Bonita Avenue, San

Dimas, CA 91773. The camera-ready copy for the Spark Arrester Guide was produced

at the SDTDC for the NWCG by the following personnel:

Ralph Gonzales—Mechanical Engineer

Janie Ybarra—Visual Information Specialist

GENERAL PURPOSE SPARK ARRESTER

INSPECTION PROCEDURES

Standard 5100-1c requires that each arrester shall

be permanently marked with the model number

and the manufacturer’s name or trademark. The

model number must match exactly. The

identification must be stamped in the metal body

or on an attached metal plate. The words

“Qualified” or “Approved” are not required, and

do not indicate that the unit is in fact a qualified

arrester.

1. If identification of the manufacturer’s name

and model number is found, then refer to the

“Qualified and Rated” list.

2. Check the “Qualified and Rated” list to

establish if the arrester is qualified.

3. If not on the “Qualified and Rated” list, be

sure to check any SAG update information you

have received since the time of the printing of

your present SAG. The absence of an arrester

from these lists indicates that the arrester has not

been qualified.

4. After the arrester has been identified, turn to

the Drawing Section and check the spark arrester

illustration for an exact match on the

configuration, dimensions and cleanout devices.

The drawing must match the spark arrester you

are inspecting.

5. Suggested tools for inspections:

a. Handtools to open cleanout, screwdriver

and pliers.

b. Flashlight.

c. 1/8-inch wire rod or stick to probe inside

the arrester to determine if stationary fan

or vanes are in place.

d. Tape measure.

e. 0.024-inch wire gauge to determine

screen size.

6. Inspect to ensure that:

a. The spark arrester is correct for the

position of application.

b.The exhaust system between the engine

and the spark arrester is in good order.

c. The arrester is properly maintained and

cleaned out when necessary.

d. There are no modifications to the

exhaust system.

7. More detailed instructions are available in the

NWCG video, “Spark Arresters and the

Prevention of Wildland Fires".

8. Follow your agency policies when an

unqualified spark arrester system is encountered.

viii

Mufflers—Experience and tests have shown that

mufflers, in general, are inadequate as spark

arresters. Few muffler devices submitted for

formal tests meet the requirements of 5100-1c or

SAE J350. However, properly maintained

baffled mufflers constructed to automotive

industry standards, and installed on motor

vehicles other than motorcycles are accepted for

“on- highway” and “off-road” use in some

jurisdictions. Exceptions are for designated areas

where a spark arrester is required on cross-

country vehicles. Straight-through mufflers, such

as glass-pack designs without baffles, are not

acceptable. Consult your agency’s policy for

more specific guidelines.

Turbochargers qualify as effective spark

arresters when 100% of the exhaust gases pass

through the turbine wheel. The turbine wheel

must be turning at all times and there must be no

exhaust bypass to the atmosphere. Depending on

design, small enclosed system bypasses that

reroute some of the exhaust back through the

engine may be allowed. The illustration of the

exhaust-driven turbocharger shows the air intake

and the exhaust path through the turbine wheel.

The action of the rotating turbine wheel causes

carbon particles to remain within the confines of

the turbo-drive section until they are reduced to a

harmless size by attrition.

Superchargers, which are strictly mechanically

driven, do not qualify.

Exhaust System—The exhaust system consists

of the manifold (on multicylinder engines),

muffler or spark arrester or both, an exhaust pipe

between the engine cylinder exhaust outlet port,

and the end of the exhaust pipe which is open to

the atmosphere.

Exhaust Manifold—A chamber into which the

exhaust from each of the engine cylinders is

collected. The exhaust is then directed out of the

manifold to a muffler or spark arrester or both.

Most large locomotive engines have the spark

arrester designed into the exhaust manifold.

Small, single-cylinder engines do not have

manifolds.

Modification—Any modification or damage to

any part of the system as it was presented to

SDTDC for testing voids the qualifications of the

spark arrester on the equipment. Modifications

usually consist of removal of or damage to parts,

change in exhaust outlets, replacing the

fiberglass packing with steel wool, improper

mounting, and bypasses.

Follow your agency policies when a modified/

unqualified spark arrester system is encountered.

The qualified positions listed include only those

tested. In some cases, the manufacturer may

claim other positions, but test information at this

time neither support or refute such claims. An

arrester tilted more than 60 degrees from its

qualified operating position may not adequately

arrest sparks. Therefore, arresters on mobile

equipment—other than screen type arresters—

shall not be mounted more than 45 degrees from

the qualified position. See column marked

“Appl Pos.”

Note that USDA Forest Service Standard 5100-

1c allows 60 degrees deviation, but at least 15

degrees should be reserved for deviations

because of road grade or slope.

(See illustration.)

Rated Flow of Arrester is the rate of test gas

flow in cubic feet per minute at which the

corresponding back pressure is 1 pound per

square inch. This is the maximum desirable back

pressure for most four-stroke cycle applications.

See column marked “Flow.” Note: General

Purpose Screen Type Spark Arresters are limited

to the listed rated flow, 2 or 4 cycle, and horse

power.

Some two-cylinder engines may require a higher

back pressure. An arrester may be used above its

rated flow—provided it maintains a qualifying

arresting effectiveness at all levels of use.

Arresters that do not have an adequate

effectiveness above their rated flow will be

designated in the “Remarks” column, and are not

qualified to operate in applications where they

may be ineffective. With this exception, a

qualified arrester properly installed and

maintained is acceptable legally regardless of

size or rated flow. It is the owner’s business if

he/she chooses an arrester too large or too small,

even though the cost may be excessive or the

back pressure too high.

Cleaning—The arrester shall have provision for

the easy disposal of the accumulated particles

without removal of the clamping or mounting

devices from the stack, pipe, or manifold

assembly. Screen-type devices shall provide for

the easy removal and cleaning or replacement of

the screen.

Marking and Labeling—Each arrester shall be

permanently marked with the manufacturer’s

model number designation and a trademark or

other identification of manufacturer. Where an

inverted installation is possible, the inlet or outlet

shall also be marked. In addition to the above

markings, screen-type devices must have the

words “Screen Type” clearly imprinted in 1/8-

inch or larger letters. The model number must

match exactly. The words “Qualified” or

“Approved” are not required, and do not

indicate that the unit is in fact a qualified arrester.

Discontinued Models will be called out under

“Remarks.”

3. Number of SAG updates which have been

issued.

4. Inventory at NIFC. Reprinting will be

done to meet supply and demand

requirements.

BASIC DEFINITIONS AND TEST

STANDARDS

Exhaust Particles—All internal combustion

engines produce exhaust particles which are

predominately carbon with contaminates. These

particles originate from deposits formed on the

internal surfaces of the engine or exhaust system

and, depending on their exact origin, may be

expelled at temperatures in excess of 3,000° F.

Depending on the nature of the contaminates,

these particles are capable of glowing or

sometimes flaming combustion. When expelled

through the exhaust system into the atmosphere,

the combustion process may continue oreven be

accelerated during flight. Such particles, if larger

than 0.023-inch in diameter and at temperatures

of 1,200° F are capable of igniting cellulose

materials upon contact.

A Spark Arrester is a device which traps or

pulverizes exhaust carbon particles to a size

below 0.023-inch in diameter, as they are

expelled from an exhaust system. Trap type

spark arresters must have a method for removal

of accumulated carbon particles. Most spark

arresters generally perform in the high 90 percent

spark arresting effectiveness range.

General Purpose Spark Arresters are tested

against USDA Forest Service Standard 5100-1c

or the latest revision of Society of Automotive

Engineers (SAE) Recommended Practice SAE

J350. Either of these documents establish the

minimum performance and maintenance

requirements of single-position application

general purpose spark arresters. Spark arresting

effectiveness shall be at least 80 percent for all

flow rates on the cold test which correlates to

90 percent on a hot engine.

Screen-Type Spark Arresters as defined by

USDA Forest Service Standard 5100-1c fall into

a special category. They are intended for use on

small engine applications. All exhaust products

must pass through the screen, which has

openings of 0.023-inch or less. The effective

exhaust area of the screen (total area of all

screen openings) shall not be less than 200

percent of the engine exhaust port area at its

smallest cross-section. Screen material shall be

heat and corrosion resistant, and shall provide at

least 100 hours of service life. These are

originally qualified for all the positions described

in the "Application Postions" section.

"Add-On" spark arresters are added onto an

existing muffler exhaust system. They are

typically used on Off-Highway-Vehicles. Add-

on spark arresters must have a method for

removal of accumulated carbon particles. Such

as a cleanout plug, snap ring, removable end cap

or a removable end cleanout. A removable end

cleanout is usually secured to the muffler by a

retaining band and/or several screws. In order to

empty out the accumulated carbon particles with

a removable end cleanout, the entire add-on must

be removed by loosening the retaining band or

screws, to shake out the carbon particles.

The retaining band or screw may not be replaced

by welding the removable end cleanout to the

existing muffler. This is considered a

modification and also does not allow for removal

of accumulated carbon particles. Any

modification to the spark arrester as compared to

the SAG line drawing in this SAG, voids

qualification.

Application Positions—Four general positions

are considered—vertical, horizontal, inverted,

and multiposition. The application is determined

by the attitude of the inlet pipe irrespective of the

main body position or direction of outlet. For

example:

GENERAL INSTRUCTIONS FOR USE OF

THE SPARK ARRESTER GUIDE (SAG)

The General Purpose and Locomotive (GP&L)

SAG is a compilation of information, lists, and

illustrations of qualified GP&L spark arrester

systems and engines—including their identifying

markings, design, and assembly.

The intent of the SAG is to provide field

inspectors with adequate information to

determine if an engine and exhaust system

combination have been tested and qualified by

the San Dimas Technology and Development

Center (SDTDC) as meeting the Standard for

spark arresting exhaust systems.

The SAG is printed as two publications. This

SAG covers General Purpose and Locomotive

(GP&L) arresters, and the other SAG covers

Multiposition Small Engine (MSE) arresters.

In each publication, there is a section for each

type of arrester with illustrations of spark

arresters listed in alphabetical order by the

manufacturer’s name, and lists of qualified and

rated spark arresters of that type. Inspectors can

use these sections to verify qualification status.

Specific instructions for use of each section

precedes the section.

Use of the SAG is also illustrated in the video

"Spark Arresters and the Prevention of Wildland

Fires" and may be used as a supplemental

instruction tool. The video contains five separate

modules titled, "Introduction, Multiposition

Small Engine, General Purpose, Off Highway,

and Railroad".

The two SAG publications and the video may be

When you receive your order, discard the old

SAG's.

UPDATES TO THE SAG

Testing of newly submitted spark arresters is an

ongoing process at SDTDC. The Center will be

responsible for notifying SAG users of newly

qualified and rated spark arresters. SDTDC will

send the information to appropriate Regional and

State offices for their distribution. Users should

contact these sources for updated information.

SAG Updates are usually mailed in July &

December.

For quick reference, updates should be inserted

in the publication for the appropriate type

arrester. These new qualified arresters will be

included with illustrations when the Guides are

reprinted. (See section that follows.)

REPRINT INFORMATION

SDTDC will determine when adequate

information has been compiled to require a

reprinting of each publication. The Center will

notify the Regional and State offices when a

reprinting is available. It is anticipated that a

reprinting may be required on odd numbered

years for the Multiposition Small Engine (MSE)

Guide and on even numbered years for the

General Purpose and Locomotive (GP&L)

Guide.

SDTDC will include the following criteria in

their reprint decision:

1. Determination of usable life of the SAG.

2. Volume and complexity of questions

received from field users. Major users will

be contacted periodically for feedback.

* = Donaldson Company, Inc., Early models may carry a “-1”

at the end of this number.

** = Super Trapp Industries, Units qualify regardless of the number

of discs used. The assigned flow rates were obtained using 18

discs. Fewer discs will give a lower flow rate and more discs will

give a higher flow rate. Nest discs so dimples interlock and tighten

retainer bolt so discs are not loose. Frequent cleaning may be

necessary to avoid plugging.

Note: Hapco models were formerly labeled Harco. Model

designations may contain a dash followed by number(s) and

letters. These signify the inlet size opening, application, and/

or thread type. Moderate inlet size differences are acceptable

from the dimensions indicated on the drawings for

identification in the next section.

cubic cubic

1Volumetric efficiency 80%; exhaust temperatures 900°F.

2For 2-cycle engines, multiply value by 2; for 2-cycle supercharged engines, multiply value by 3.25; for 4-cycle supercharged

engines, multiply value by 1.25.

3The "RPM Differential" column gives the difference between RPM columns for interpolation purposes. Entries are

to the nearest whole number.

General— All chart values are proportional, so a flow can be calculated for a 1000-cubic-inch engine by doubling

the flow figure for an identical engine but with 500-cubic-inch displacement. The same rule applies to revolutions

per minute. Therefore, a flow can be calculated for a 3000 maximum rpm engine by doubling the flow value of an

identical engine but with 1500 maximum rpm.

This chart may also be used like an interest table. If the engine has a cubic inch displacement of 438 at 2600 revolutions

per minute select readings from 400, 30, and 8 at 2600 rpm. The sum of these is the flow rate. When revolutions

per minute fall between columns, ie., 1600 to 1800. 1800 to 2000, etc., take the next highest rpm column. To be

more exact interpolate by using the "RPM Differential" value.

EXAMPLE: A 4-cycle diesel engine has a total displacement of 633 cubic inches. If its maximum rpm is 2600, what

is the maximum exhaust flow?

Solution— 600 cu. in. displacement @ 2600 rpm=876; 30=44; and 3=4; Sum=924 cfm.

1Volumetric efficiency 80%; exhaust temperatures 1200°F.

2For 2-cycle engines, multiply value by 2 and for 4-cycle supercharged engines, multiply value by 1.25.

3The "RPM Differential" column gives the difference between RPM columns for interpolation purposes. Entries are

to the nearest whole number.

General— All chart values are proportional, so a flow can be calculated for a 1000-cubic-inch engine by doubling

the flow figure for an identical engine but with 500-cubic-inch displacement. The same rule applies to revolutions

per minute. Therefore, a flow can be calculated for a 3600 maximum rpm engine by doubling the flow value of an

identical engine but with 1800 maximum rpm.

This chart may also be used like an interest table. If the engine has a cubic inch displacement of 438 at 2600 revolutions

per minute select readings from 400, 30, and 8 at 2600 rpm. The sum of these is the flow rate. When revolutions

per minute fall between columns, ie., 1600 to 1800. 1800 to 2000, etc., take the next highest rpm column. To be

more exact interpolate by using the "RPM Differential" value.

EXAMPLE: A 4-cycle gasoline engine has a total displacement of 133 cubic inches. If its maximum rpm is 3200,

what is the maximum exhaust flow?

Solution— 100 cu. in. displacement @ 3200 rpm=219; 30=66; and 3=7; Sum=292 cfm.

General. —All chart values are proportional, so a flow can be calculated for a 1000-cubic-inch engine by doubling

the flow figure for an identical engine but with 500-cubic-inch displacement. The same rule applies to revolutions

per minute. Therefore, a flow can be calculated for a 3000 maximum rpm engine by doubling the flow value of an

identical engine but with 1500 maximum rpm.

The chart may also be used like an interest table. If a 2-cycle motorcycle has a cubic centimeter displacement of

125 at 7500 revolutions per minute, select readings from 100, 20, and 5 in the 8000 rpm column. The sum of these

is the flow rate for a 4-cycle engine. When revoltions per minute fall between columns, ie., 7000 to 8000, etc., take

the next highest column. To be more exact, interpolate. For the 2-cycle engine, multiply the chart value by two.
