Cleaning and Disinfection
WARNING
DO NOT use any cleaning substances that can or might attack any part of the SCBA.
DO NOT use alcohol because it may deteriorate rubber parts.
If not rinsed thoroughly, cleaning agent residue may irritate the wearer's skin.
Failure to follow these warnings can result in serious injury or death.
Depending on the cleaning policy adopted, either a designated person or the user should clean each
device after each use. ANSI standards suggest that users should be trained in the cleaning procedure.
Confidence Plus® Cleaning Solution (P/N 10009971) from MSA is recommended. It cleans and disinfects in one operation. It retains its germicidal efficiency in hard water to inhibit the growth of bacteria.
It will not deteriorate rubber, plastic, glass, or metal parts. Refer to the label for user instructions.
If the SCBA is soiled (i.e. heavy smoke residue or dirt accumulation) use a sponge damp with mild
soap solution or use a soft/medium bristle brush to remove deposits that may interfere with normal
operation of:

Harness (straps and buckles)
Carrier (band and latch assembly)
Cylinder (handwheel, gauge, outlet connection)
Pressure reducer (bell and coupling nut connection)
Control module/power module/battery module/speaker module
Inspect the entire SCBA as it is reassembled. Follow the Inspection Instructions.

12.1 Safety Precautions for MSA Self-Contained Breathing Apparatus Cylinders
WARNING
This system must be supplied with respirable [Quality Verification Level (Grade) D, see ANSI/
CGA G-7.1-1989] or higher quality air; and a dew point not to exceed -65°F/-54°C
(24ppm v/v) [Compressed Gas Association Specification G-7.1 for Quality Verification Level
(Grade) D Gaseous Air]. In fire service applications, MSA recommends breathing air quality in
accordance with NFPA 1989.
DO NOT drop the cylinder or bump the valve knob. An unsecured cylinder can become an
airborne projectile under its own pressure if the valve is opened even slightly.
Never carry or move a cylinder by the handwheel. If a cylinder is removed from a horizontal shelf
by grasping the handwheel, the weight of the cylinder can cause the cylinder to rotate downward
causing the valve to open slightly.
Avoid dropping the cylinder or bumping the handwheel.
Use the handwheel only to open and close the cylinder valve.
A valve could partially open causing the cylinder to become an airborne projectile under its own
pressure and result in serious personal injury or death.
Remove from service if cylinder shows evidence of exposure to high heat or flame: e.g., paint
turned to a brown or black color, decals charred or missing, gauge lens melted, or elastomeric
materials distorted.
Use this device only after receiving proper training in its use. Use in accordance with this label
and MSA apparatus instructions.
To maintain NIOSH approval, the cylinder must be fully charged with respirable air meeting the
requirements of the Compressed Gas Association specification G-7.1 1989 for Quality Verification Level (grade) D air or equivalent specification. In fire service applications, MSA recommends
breathing air quality in accordance with NFPA 1989.
Do not use unless the cylinder is filled to the maximum working pressure.
Do not alter, modify, or substitute any components without approval of the manufacturer.
Inspect frequently. Maintain according to manufacturer's instructions. Repair only by properly
trained personnel.
US
Misuse can result in serious injury or death.
Breathing apparatus cylinders should be fully recharged as soon as possible after use.
G1
67
Cylinders
Cylinders should not be stored partially charged:
If used partially charged, the duration of the SCBA is reduced.
The pressure relief device is only designed to protect a fully charged cylinder from the effects of a
fire.
For maximum safety, the cylinders should be stored full or at a pressure above ambient but less than
100 psi.
Prior to recharging, cylinders must be examined externally for evidence of high heat exposure, corrosion, or other evidence of significant damage.
Additional information of value when performing external and internal inspections of cylinders may be
found in the latest editions of CGA Publication C-6.2: “Guidelines for Visual Inspection and Requalification of Fiber Reinforced High Pressure Cylinders” available from the Compressed Gas Association,
Inc., 1725 Jefferson Davis Highway, Suite 1004, Arlington, VA 22202-4102.
If there is any doubt about the suitability of the cylinder for recharge, it should be returned to a certified
hydrostatic test facility for expert examination and testing.
Always check to be sure the retest date is within the prescribed period and that the cylinder is properly
labeled to indicate its gaseous service. New labels are restricted items which are not available except
through certified hydrostatic test facilities.
When replacing cylinder valves or after the retesting of cylinders, make sure the proper cylinder valve,
burst disc, and o-ring are installed prior to cylinder recharging. Determine the maximum service pressure of the cylinder. All cylinders shall be filled to the designated service pressure only (as found on
the DOT approval or stamping). For cylinders manufactured under a U.S. DOT exemption (i.e., DOTE- #####), the exemption should be consulted and is available from the Associate Administrator for
Hazardous Materials Safety, Research and Special Programs Administration, U.S. Department of
Transportation, 400 7th Street, SW, Washington,
D.C. 20590-0001.

UAC Fitting
13
UAC Fitting
All NFPA 1981, 2013 Ed. approved SCBAs are equipped with a UAC (Universal Air Connection)
fitting. The UAC fitting is a male Quick-Fill inlet for use by Rapid Intervention Teams for emergency
filling operations. The system also includes an automatically resetting pressure relief valve. The SCBA
can also be equipped with a waist mounted Quick-Fill System. For additional information on using the
Quick-Fill System, refer to the Quick-Fill System section of the manual. The UAC fitting may be used
for transfill operations as described in this manual. Only qualified, trained personal should perform
operations using the UAC fitting. Standard Operating Procedures should be developed for use of the
UAC fitting.
13.1 Precautions
The UAC fitting can only be used to fill approved SCBA cylinders.
The user is responsible for the air supply, which must meet the requirements of Compressed Gas
Association Specification ANSI/CGA G-7.1, Quality Verification Level (Grade) D Gaseous Air or
better, with a moisture dew point of not greater than -65°F/-54°C (24ppm water vapor, normal). In
fire service applications, MSA recommends breathing air quality in accordance with NFPA 1989.
Pressures at the inlet of the Quick-Fill hose must not exceed that of the SCBA (2216 psi or 4500
psi).
The user also is responsible for connecting the Quick-Fill hose to an appropriate secondary air
supply.
The cylinder must be inspected for damage before charging.
If topping off the cylinder using the UAC fitting, it is recommended to wait until after the cylinder
has cooled from initial fill. Topping off a cylinder after it has cooled will ensure proper service time.
WARNING
DO NOT use the UAC fitting as a “Buddy Breather” such that two users are sharing the air
supplied by one approved SCBA cylinder simultaneously; doing so will void NIOSH approval.
The UAC fitting must be used by trained personnel only.
DO NOT lubricate the UAC fittings. Do not permit oil, grease, or other contaminants to come in
contact with the UAC fittings.
The hose assemblies and fittings are designed to be used with Quality Verification Level (Grade)
D or better air as defined by ANSI/CGA G-7.1.TRANSFILLING AIR FROM A SECONDARY AIR
SUPPLY. In fire service applications, MSA recommends breathing air quality in accordance with
NFPA 1989.
US
Misuse can result in serious injury or death.
NOTE: The UAC fitting may be used for transfill operations as described in this manual. Standard
operating procedures should be developed for use of the UAC fitting.
The UAC fitting must be used only by qualified, trained personnel who have carefully read and understood these instructions, cautions, and warnings. NIOSH approvals of SCBA from MSA are maintained while transfilling air only if appropriate hose assemblies from MSA are used. UAC fitting or hose
assemblies and fittings are rated for a maximum working pressure of 4500 psi. Use the following hose
assemblies: 485331, 802687, 802688, 802689, 802690, and 485332, for filling cylinders in IDLH
atmospheres.
G1
74
UAC Fitting
13.2 Filling Instructions
A secondary air supply stores compressed breathing air until needed to refill SCBA air cylinders.
When transfilling, the secondary air supply pressure must be greater than SCBA cylinder pressure.
Examples of air supplies include: cascade air cylinder refilling systems; high pressure compressor
systems with a fixed reservoir; or a portable air system such as the RescueAire™ System.
WARNING
DO NOT connect a high pressure SCBA to a secondary air supply with a pressure greater than 4500
psi. The high pressure SCBA is rated for a maximum working pressure of 4500 psi.
Misuse can result in serious injury or death.
NOTE: Rapid Intervention Teams should use a separate air supply such as MSA's RescueAire portable air supply system to fill the SCBA in an IDLH atmosphere.
(1)
Connect the Quick-Fill hose to the secondary air supply.

Turn the air supply on.
CAUTION
If there are leaks from either female fitting, or along the hose, depressurize the hose and correct the
problem. Such leakage can result in increased fill time.
Attach the Quick-Fill hose to the UAC fitting:
(2)
Remove the rubber dust cap from the male inlet fitting on the UAC fitting. Be sure that the
cylinder valve is fully opened.
(3)
Remove the rubber dust cap from the female fitting on the Quick-Fill hose.
(4)
Push the female fitting of the hose onto the male fitting of the UAC fitting until it snaps in place.
(5)
Pull on the hose to be sure the connection is secure.

Filling immediately begins when the female fitting fully engages with the UAC fitting.

After approximately 60 seconds, the pressure between the secondary air supply and the
SCBA cylinder will be equal.
US
WARNING
If serious leakage is noticed from either of the two female fittings, or anywhere along the hose,
disconnect the female fittings and return to fresh air immediately.
Misuse can result in serious injury or death.
NOTE: If the secondary air supply does not have a sufficient volume of air, the SCBA cylinder will not
reach full service pressure.
(6)
Compare the cylinder pressure gauge and the remote pressure gauge to the secondary air
supply pressure gauge reading.

(7)
If the readings are the same, pressure is equal.
To disconnect the Quick-Fill hose after transfilling, pull the gray sleeve back.

The hose fitting and the UAC fitting will separate.
G1
75
UAC Fitting
(8)

A hiss or pop may be heard as the fittings separate and the high pressure air is sealed off.

Listen for any leaks from the UAC fitting.
Immediately install the dust cover on the UAC fitting.

The SCBA cylinder is ready for service if the cylinder pressure gauge needle is on the appropriate color band.
13.3 Transfilling between SCBAs
The SCBA with the higher pressure reading is the donor. The SCBA with the lower pressure is the
receiver. Transfilling between users of SCBAs should be performed only during life-threatening emergencies or simulated training exercises. Both donor and receiver must return to fresh air immediately
following the procedure.
WARNING
DO NOT transfill if the donor's primary low pressure warning device is sounding or HUD/control
module are flashing red. Failure to follow this warning can result in shorter escape time to return to
fresh air, causing serious personal injury or death.
The low pressure warning device begins alarming and HUD/control module begins flashing red to indicate that the pressure in the cylinder has been reduced to 35% of its rated working pressure.
Remaining service time must be used for escape to fresh air. If the donor's primary low pressure
warning device begins ringing or HUD/control module begins flashing red during transfilling, the donor
should disconnect and preserve his escape time.
If the donor's primary low pressure warning device is not sounding and HUD/control module are not
flashing and there is sufficient air to transfill to a receiver, (greater than 1000 psi for 2216 psi SCBAs
and greater than 2000 psi for 4500 psi SCBAs), follow these steps:
(1)
Remove the 3 foot emergency transfill hose from its protective pouch.
(2)
Remove the rubber dust cover from both female fittings on the transfill hose assembly.
(3)
Remove the rubber dust cover from the UAC fitting.
(4)
Push the female fittings on to the male fittings until they click in place.

Pull on the hose to be sure it snapped in place.

After approximately 60 seconds, pressure between the SCBA cylinders will be equal.
US
WARNING
If serious leakage is noticed from either of the two female fittings, or anywhere along the hose,
disconnect the female fittings and return to fresh air immediately.
Misuse can result in serious injury or death.
(5)
Disconnect the transfill hose from the SCBA by pulling the gray sleeve back on both ends.

(6)
A hiss or pop may be heard as the fittings separate and the high pressure air is sealed off.
Immediately install the dust cover on the UAC fitting. The dust cover prevents dirt, water, and
debris from entering the fitting, and acts as a redundant seal.
G1
76
UAC Fitting
13.4 Leakage
When transfilling in fresh air and the dust cover will not stay on the male fitting because air is leaking:
(1)
Correct the condition before using the SCBA.
When transfilling in a contaminated atmosphere and the dust cover will not stay on the male fitting
because air is leaking:
(1)
Immediately reconnect the Quick-Fill hose to seal off the leak and return to fresh air.
(2)
If the hose will not reconnect, reach behind and close the cylinder valve.

(3)
Quickly replace the protective dust cap on the male fitting.

(4)
Air pressure in the regulator will drop, and the leak will slow down.
This will form a redundant seal.
Open the cylinder valve and return to fresh air immediately.

The dust cover prevents dirt, water, and debris from entering the fitting, and acts as a redundant seal.
Emergency Transfill Hose Storage

G1 ExtendAire II EBSS
General Information
Two air masks equipped with a G1 ExtendAire II System can share a common air supply during emergency escape.
NOTE: Activation of EBSS changes both the donor and receiver to Escape Only, and the user must
immediately evacuate to fresh air outside the hazard zone.
Users can couple the G1 Second Stage Regulator from one user to the intermediate pressure manifold of the other user. Both users will receive intermediate pressure air from the donor's pressure
reducer and cylinder. The duration of the remaining air supply will be reduced by at least half.
NOTE: The National institute for Occupational Safety and Health (NIOSH) did not approve the interconnection of apparatus using "Buddy Breathers" or EBSS prior to NFPA 2013-edition standard units.
Interconnection of pre-2013 edition SCBAs with an EBSS device results in a non-approved NIOSH
configuration.
WARNING
Users must be trained in the operation of EBSS in accordance with a training program conforming
to NFPA Standards 1404 and 1500 prior to any attempt to use such equipment in an emergency situation. Misuse can result in serious injury or death.
CAUTION
Use this emergency escape breathing system for life threatening emergencies and simulated
training exercises only. All other adequate means of escape must be considered before using this
device.
During use, the air supply and consequentially the remaining service time is reduced approximately in half. Before connecting two users make sure the air supply is sufficient for both users
to escape; otherwise do not use the system.
DO NOT use the system is the donor's low pressure warning device is alarming (ringing). Using
the system at this time can result in both users running out of air during escape.
Exercise extreme care while connected together. Mobility and range of motion will be limited
when donor's and receiver's air masks are connected.
Maintain slack in the air lines during maneuvering and while connected together. DO NOT pull on
the hoses. Pulling on the rescue hose to the intermediate pressure hose could separate the
hoses from fittings and result in air leaks.
US
If the above measures cannot be followed or to provide greater escape protection, use the Quick-Fill
System. Use of Quick-Fill maintains approval while transfilling and does not exhibit the above
hazards.
WARNING
DO NOT use the Quick-Fill System, URC assembly or G1 ExtendAire II System accessories if there
is any possibility that the environment contains a CBRN warfare agent. These air mask accessories
are not approved for the use in atmospheres containing CBRN warfare agents. Failure to follow this
warning can result in serious personal injury or death

Flow Test and Overhaul Requirements

Flow Test and Overhaul Requirements
The regulator and primary low pressure warning device must be flow tested at specific time intervals.
These maintenance procedures must be performed by a certified repairperson or at an MSA service
center. Contact your MSA sales representative or call the MSA Customer Service Center at 1-877MSA-3473 for more information about these requirements.
Annual flow tests are stated as a requirement in NFPA 1852, Standard on Selection, Care, and Maintenance of Open-Circuit Self-Contained Breathing Apparatus (SCBA), 2013 Edition, which further
emphasizes their importance. Although this standard relates to SCBA used in the fire service, MSA
requires that a flow test be performed at least annually on all fire service and non-fire service SCBA
and combination respirators that use a regulator.
MSA recommends the routine inspection of all elastomeric materials including, but not limited to those
in the Visual Inspection and Functional Check section of this manual.
A decision to retire apparatus should be based on an SCBA's performance data and whether that data
meets the specified level of performance as defined in maintenance requirements from MSA.
MSA recommends overhauling the SCBA every 600 hours of on air usage. The amount of on air
usage can be found in the service mode of the SCBA.

Personnel ID Tag

Personnel ID Tag
An ID Tag is used to assign a user's name to the SCBA. The name assigned to the SCBA will be
displayed for that SCBA on the MSA Accountability System Software and data log within the SCBA.
The name ID Tag must be scanned into the power module at the start of each shift (every 24 hours
by default) or prior to each use.
NOTE: The MSA A2 Software can be used to change this default to allow a name ID to be permanently assigned to the SCBA until a new name ID Tag has been scanned.
A team ID Tag can also be used to assign a team/truck and position to the SCBA. If a team ID Tag
has been scanned into the control module but a name ID Tag has not been scanned, the team ID will
be displayed on the SCBA monitoring software to provide accountability even if the firefighter forgot
to scan the name ID Tag. Once a team ID Tag has been scanned into the control module, the team
ID will remain with the SCBA until another team ID Tag has been scanned. If a team ID or name ID
has not been assigned to the SCBA, the power module serial number will be displayed as the firefighter's ID when logged onto the base station.
A base station ID can be used to assign a specific base station ID to an SCBA. When more than one
base station is present and actively monitoring at an incident, an SCBA with an assigned base station
will search for the preferred base station first to log on to, and if it does not find the assigned base
station within 20 seconds, it will search for the first available base station and log on to it. If a base
station ID has not been assigned to the SCBA, it will log on to the first base station that it finds once
the unit has been turned on. Once a base station ID tag has been scanned into the power module,
this base station ID will remain with the SCBA until another base station ID tag has been scanned.
The ID Tag has a space for the user to place a label in which the ID information can be written on the
outside of the ID Tag for easy identification.
Before using the ID tag, inspect for damage or cracks in the case. If damage is found, discard and
replace the ID tag.
