DESCRIPTION
DESCRIPTION
The Air Masks from MSA are pressure-demand, self-con-
tained breathing apparatus (SCBA) certified by the
National Institute for Occupational Safety and Health
(NIOSH) for use in atmospheres immediately dangerous to
life or health:
``Immediately dangerous to life or health’’ means condi-
tions that pose an immediate threat to life or health or
conditions that pose an immediate threat of severe expo-
sure to contaminants, such as radioactive materials,
which are likely to have adverse cumulative or delayed
effects on health’’ [Title 42 CFR, Part 84.2, (Q)]
• This SCBA is not compliant with National Fire
Protection Association (NFPA) Standard 1981. The
SCBA should not be used for firefighting applica-
tions where NFPA compliance is required.
• This SCBA is not NIOSH approved for use against
CBRN live agents. If NIOSH CBRN Agent Approval
is required, use a NIOSH CBRN Agent approved
Firehawk Air Mask.
• This SCBA must be equipped with an Ultra Elite
Hycar facepiece (model numbers 7-935-7. 7-935-8,
and 7-935-9) and a CBRN regulator (model num-
bers 10060982 or 10060983) when exposure to
CBRN live agents is possible. Do NOT use a sili-
cone facepiece or a regulator that is not identified
as CBRN regulator against CBRN live agents.
Failure to follow these warnings can result in serious
personal injury or death.
AirHawk MMR breathing apparatus consists of the follow-
ing major sub-assemblies.
• first stage regulator
• second stage regulator
• air cylinder and valve
• whistle audible alarm
• carrier and harness
•facepiece
FIRST STAGE REGULATOR
The first stage regulator is a "balanced-type’’ pressure
reducer that keeps the pressure to the mask mounted
regulator at approximately 80 psig throughout the entire
operating pressurerange of the cylinder. The regulator has
aredundancy feature to minimize the possibility of a first
stage failure. The regulator uses a large sintered filter
which is easy to replace. The filter captures particulates
that may be in the air stream.
SECOND STAGE REGULATOR
This is a pressure-demand regulator, which keeps a posi-
tive pressure in the facepiece all the time. The release
button on top of the regulator stops air flow. To stop air-
flow, push the button in. To restart the regulator, inhale
sharply. The regulator attaches to the facepiece with a
Push-To-Connect connector or slide connector. The regu-
lator delivers large flow rates accurately and quickly.
Airhawk SCBA with the Firehawk MMR (model numbers
10060982and 10060983) are considered by MSA to be
“CBRN hardened.” They can be identified by Firehawk
Regulator model number and the CBRN marking on the
underside of the regulator housing. SCBA with these reg-
ulator models have passed CBRN live agent testing, but
are not CBRN-approved by NIOSH since they are not cer-
tified as NFPA compliant.
AIR CYLINDER AND VALVE
*as approved by NIOSH
The air cylinder and valve consists of a tank and a cylin-
der valve assembly.The cylinder valve includes a valve
body,cylinder valve inlet tube, handwheel, safety disc
(burst disc), and pressure gauge. The pressure gauge
shows the air pressure in the cylinder continuously. The
gauge is calibrated in 100 psig increments. For example,
agauge reading of 20 is read as 20 x 100 or 2,000 psig. A
handwheel is used to open and close the cylinder valve.
WHISTLE AUDIBLE ALARM
The whistle audible alarm sounds when there is approxi-
mately 25% of the SCBA’srated service time remaining.
The whistle also sounds when the cylinder valve is first
opened, providing an audible indication that the alarm is
functioning.

DESCRIPTION
CARRIER AND HARNESS
The carrier consists of a backplate, a cylinder strap with
buckle to hold the cylinder, and a harness, consisting of
shoulder straps, chest strap (optional), adjustable pull-
straps waist-strap, shoulder pads (optional) and belt
mounted regulator retainer.
LUMBAR PAD (OPTIONAL)
The lumbar pad with a flared design is designed to pro-
vide a cushion between the wearer and harness. The
flared design evenly distributes cylinder weight across the
wearer’s hips.
FACEPIECE
The facepiece is available in three sizes.
Only Ultra Elite Hycar facepieces (model numbers 7-935-
7, 7-935-8, and 7-935-9) have been tested against and
meet CBRN live agent test requirements. Silicone face-
pieces are NOT CBRN-approved.
The facepiece has a low-resistance, pressure-demand
exhalation valve designed for easy cleaning. An inhalation
check valve in the inlet housing keeps moisture and cont-
aminants out of the mask mounted regulator. The face-
piece has a speaking diaphragm for clear, short-range
communication.

DONNING
DONNING THE AIR MASK
1. Remove the facepiece from the case.
Donot use a cover lens in a high-temperature environ-
ment. High temperatures may distort the cover lens,
ormoisture trapped between a cover lens and the
facepiece lens may condense and distort vision.
Always remove the cover lens before donning the
facepiece.
2. Check that the cylinder is fully pressurized.
If the cylinder is not full, the service time is reduced
accordingly & should not be used.
3. Reach inside the right shoulder straps and grasp the
pressuregauge, slide left armthrough left shoulder
straps.
4. Bend forward slightly, rest it on your back.
5. Attach the chest strap (optional).
6. Fasten the waist-strap and pull it tight for a snug fit.
7. As you straighten up, pull the shoulder strap tabs out.
Hike the unit up for a comfortable fit.
8. The shoulder straps and waist-strap ends must be
tucked in and lay flat across the body.
REGULATOR AND WHISTLE AUDIBLE ALARM
CHECKS TESTING
1. Grasp the mask mounted regulator and push the top
release button.
2. Check that the red
bypass knob is fully
closed (clockwise).
3. Reach behind and
open the cylinder valve
fully. Listen for the
whistle to sound briefly.
4. As the pressure rises from 50 to 200 psig, the alarm
sounds automatically, indicating that the alarm is func-
tional.
If the whistle fails to sound, do not use the apparatus.
The SCBA must be checked and corrected for proper
operation by an MSA trained or certified repairperson
before using. Failure to follow this warning may result
in serious personal injury or death.
5. No air should flow from
the regulator. If it does,
repeat steps 1 and 2.
6. Check the gauge and cylinder gauges. Gauges must
be within 220 psig for 2216 psig; 450 psig for 4500
psig.
If your readings do not agree with these values, return
the SCBA to an MSA trained or certified repairperson.
7. Check for bypass oper-
ation. Grasp the red
knob and turnit
counter-clockwise.
Listen for airflow, then
turnit OFF. Close cylin-
der valve fully.

DONNING
8. Check for air leaks. Open cylinder valve fully to pres-
surize system, then close the cylinder valve and watch
the harness pressure gauge.
9. If the needle drops more than 100 psi in 10 seconds,
there is a leak. Do not use the apparatus until the leak
is found and corrected.
10. Crack the bypass valve slowly to bleed off pressure
until gauge needle drops below:
550 psig - approximately (low-pressure system) or,
1125 psig – approximately (high-pressure system)
The whistle will sound. The whistle must continue to
sound until pressure is less than 200 psig. Close the
bypass fully.
If the whistle fails to sound, do not use the apparatus.
The SCBA must be checked and corrected for proper
operation by an MSA trained or certified repairperson
before using. Failure to follow this warning may result
serious personal injury or death.
Note: Before donning, check that the regulator sealing
ring is seated properly in its groove, and that it is not torn,
gouged, or nicked.
DONNING THE FACEPIECE
Do not wear eye glasses under the facepiece. The
temples or sidebars on eye glasses will prevent an air-
tight seal. if you must wear glasses, install the specta-
cle kit. Failureto follow this precaution may cause
inhalation of contaminated air,resulting in serious res-
piratory injury or death.
1. Extend the facepiece straps fully. Place neckstrap
around your neck and don the facepiece by inserting
your chin first.
2. Pull the head harness
completely over your
head and tighten the
lower (neck) straps.
3. Tighten the lower (neck) harness straps first, by pulling
them straight back, not out. Tighten the temple straps
the same way. Tuck in the ends of the straps so that
they lay flat across the head.
4. Push headband pad towards neck, retighten the
straps (if necessary) for best visibility and fit. Tuck in
the ends of the straps so they lie flat across the head.
FACEPIECE FIT CHECK
Check the inhalation valve, inhale. If you do not
receive sufficient flow of air, do not use facepiece. The
facepiece must be repaired or replaced.
1. To check for facepiece
fit, hold the palm of
your hand over the inlet
connection and inhale.
Hold your breath at
least 10 seconds. The
facepiece should col-
lapse and stay col-
lapsed against your
face. If it does not,
readjust the facepiece
and test again. If this
does not correct the leak, do not use the face-
piece.
2. Test the exhalation
valve, take a deep
breath and hold it.
Block the inlet connec-
tion with the palm of
your hand and exhale.
If the exhalation valve
is stuck, you may feel a
heavy rush of air
around the facepiece.
Note: You may need to exhale sharply to open the valve.
If this does not release the valve, do not use the face-
piece.
This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical
characteristics (see ANSI Z88.2). An improper facial
seal may allow contaminants to leak into the face-
piece, reducing or eliminating respiratory protection.
Do not use this device if such conditions exist. The
face-to-facepiece seal must be tested before each
use. Never remove the facepiece except in a safe,
non-hazardous non-toxic atmosphere. Failure to fol-
low this warning can result in serious personal injury
or death.

WARNING

REMOVING THE APPARATUS
1. Be sure there is no
pressure in the system
before replacing a cylin-
der. Disconnect the
coupling nut.
2. Lift over center buckle to loosen the cylinder strap.
3. Slide out the empty cylinder and install one that is fully
charged. Be sure that the adjustable cylinder buckle is
properly adjusted.
4. Slide the fully charged cylinder into the carrier, with
gauge facing out, close the over center buckle to
tighten the cylinder strap.
5. To check that the cylinder is secure, place one hand
on the backplate and grasp the cylinder valve with the
other. Try to pull the cylinder and valve down and out
away from the carrier. Make sure that the strap and
buckle hold the cylinder securely in the carrier.
Note: If the cylinder feels loose, re-check that the strap
and buckle are properly adjusted. Open cylinder buckle.
Tighten cylinder strap by pulling on top (outer) strap. It will
be necessary to reposition the black plastic slide during
adjustment. Tighten cylinder strap until cylinder buckle is
approximately 45° from vertical. Close the cylinder buckle.
Do not use the Air Mask if the cylinder is not held securely
in the carrier.
Over adjusting the cylinder strap will damage the cen-
ter buckle assembly.
6. Check that the O-ring is inside the coupling nut. If the
O-ring is damaged it must be replaced beforethe
alarm is used.
7. Thread the coupling nut to the cylinder valve and
hand-tighten (no tools).
CHARGING CYLINDERS
Always check to be surethe hydrostatic test 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 only available through certified
hydrostatic test facilities.
Inspect the cylinder body for cracks, dents, weakened
areas, corrosive agent, causing the fibers to break or peel,
or signs of heat-related damage. If the cylinder is dam-
aged, return it to an MSA Service Center. Call 1-800-
MSA-2222 for instructions.
When replacing cylinder valves or after retesting of cylin-
ders, make sure the proper cylinder valve, burst disc, and
gasket are installed prior to cylinder recharging. Establish
the service pressure of the cylinder. Type 3AA (steel) cylin-
ders that bear a plus (+) sign after the latest retest date
may be recharged to a pressure 10% greater than the
stamped service pressure, i.e., a cylinder stamped
3AA2015 with a plus (+) sign after the latest test date may
berecharged to 2216 psig (this applies to steel cylinders
only). Steel cylinders without a plus (+) sign stamped after
the latest test date must be removed from service. All
other cylinders which are not type 3AA shall be filled to the
designated service pressure only (as found on the DOT
approval label or stamping). Appropriately connect the
cylinder to the filling recharge system and refill. Terminate
the filling when the pressure reaches service pressure and
allow the cylinder to cool to room temperature.
If necessary, top-off the cylinder such that service pres-
sure is attained with the cylinder at a temperature of 70°F.
Close the valves on the cylinder and the recharge system
and remove the cylinder.Apply a soap solution to deter-
mine if there is any leakage between the cylinder and the
valve. If there is no leakage, the cylinder is now ready for
re-use.
STORAGE
Do not store the apparatus or spare cylinders within or
near an area where the apparatus can or might be
exposed to any substances that will or might attach any
part of the apparatus, causing the apparatus NOT to per-
formas designed and approved.
Be careful not to drop cylinder or bump valve knob. An
unsecured cylinder can become an airborne projectile
under its own pressure if the valve is opened even
slightly.Failureto follow this warning can result in
serious personal injury or death.
Do not store the apparatus with an empty or partly filled
cylinder. Always install a fully-charged cylinder so that the
apparatus is ready for use. Complete Inspection and
Cleaning and Disinfecting Procedures areoutlined in this
manual. Ensure the complete apparatus is clean and dry.
Ensure the facepiece head harness adjustment straps are
fully extended. Place the complete apparatus in the stor-
age case or suitable storage location so it can be easily
reached for emergency use.

COLD WEATHER OPERATION
SUGGESTED PROCEDURES FOR COLD WEATHER
OPERATION
Moisture can cause problems in Air Masks if it freezes.
However, moisture can cause freezing problems even if
the surrounding air is above freezing. This is due to air
flowing from the cylinder through the regulator drops from
cylinder pressure to close to atmospheric pressure very
quickly. As it does so it expands, causing the air and the
regulator to become colder. Although the surrounding
temperature may be warmer than 32°F, the temperature
inside the regulator may be lower. Any water inside could
turn to ice and restrict airflow.
1. To keep moisture from entering the mask-mounted
regulator. Stow the regulator in the STAND-BY belt
mount.
2. When the Air Mask is away from heat, water spray can
freeze on the regulator surface. Ice can build up and
freeze the buttons, bypass valve, and the release tabs.
Before entering or re-entering a hazardous atmos-
phere, make surethe buttons, release tabs, and
bypass valve are ice-free and operating properly.
Periodically, check the bypass to be sure it is ice-free.
3. Moisture can enter through the cylinder valve or cou-
pling nut when cylinders are replaced on the Air Mask.
When replacing cylinders, be careful to prevent mois-
ture or contamination from entering the system.
Remove any ice from these fittings. Wipe the coupling
nut threads and cylinder valve threads dry before dis-
connecting the cylinder. Water can contaminate the
system and freeze.
4.NIOSH certification requires a nosecup at tempera-
tures below 32°F. The nosecup reduces lens fogging
and must be used whenever freezing conditions are
encountered.
5. Thoroughly dry the facepiece and mask mounted reg-
ulator after cleaning and disinfecting. Follow
Confidence Plus®Cleaning Solution Instructions.

CLEANING AND DISINFECTING
CLEANING AND DISINFECTING
Depending on the cleaning policy adopted, either a desig-
nated 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 recom-
mended. 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 label for user instructions.
DO NOT use any cleaning substances that can or
might attack any part of the apparatus.
Alcohol should not be used as a germicide because it
may deteriorate rubber parts.
If not rinsed thoroughly, cleaning agent residue may
irritate the wearer’s skin.
1. Preparing Solution
a. Follow the instructions with the Confidence Plus
Cleaning Solution.
b. If the Confidence Plus Cleaning Solution is not
used, wash in a mild cleaning solution, rinse thor-
oughly,and submerge in a germicide solution for
the manufacturer’s recommended time.
2. Clean and Disinfect the Facepiece
a. Remove the mask mounted regulator from the face-
piece.
b. Thoroughly wash the facepiece (and nosecup) in the
cleaning solution. A soft brush or sponge can be
used to clean the soiled facepiece.
c. Rinse the facepiece and components in clean,
warm (110°F), water (preferably running and
drained).
d. Clean the pressure demand exhalation valve by
pressing in on the stem with a blunt object and
flushing with clean water.
e. Allow the facepiece to air dry. Do not dry the parts
byplacing them near a heater or in direct sunlight.
The rubber will deteriorate.
f. Operate the exhalation valve by hand to be sure it
works properly.
Note: Do not force-dry the parts by placing them in a
heater or in direct sunlight. The rubber will deteriorate.
When the facepiece is thoroughly dry, store the facepiece
in the plastic bag that it was shipped in.
3. In general, only the facepiece requires cleaning and
disinfecting after each use. If the apparatus 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:
a. Harness (straps and buckles)
b. Cylinder carrier
c. Cylinder (coupling nut, gauge, outlet connection)
d. Whistle audible alarm
e. MMR remote gauge lens
f. First stage regulator
g. MMR second stage regulator. Cover outlet of the
MMR second stage regulator to prevent water,dirt
or debris from entering.
4. Inspect the entireapparatus as you re-assemble it.
Follow the Inspection Instructions.
5. Thoroughly dry the facepiece and regulator after
cleaning and disinfecting. The facepiece can trap
water which could enter the regulator.

INSPECTION
INSPECTION
Inspect the entire SCBA after it is cleaned and disinfect-
ed. ANSI Standards Z88.2 and Z88.5, describe three lev-
els of inspection procedures which are to be performed.
Refer to these documents, or to an inspection program
prepared by a health professional in establishing an
inspection program. Detailed repair procedures are locat-
edin MMR User’s Maintenance Instructions.
If the Air Mask does not meet any of the following
inspections, it must be removed from service.
Do not inspect the Air Mask before cleaning if there is
danger of contacting hazardous contaminants. Clean
and disinfect first, then inspect. Failure to follow this
warning can cause inhalation or skin absorption of the
contaminant and result in serious personal injury or
death.
COMPONENT INSPECTION
(AFTER EACH USE AND MONTHLY)
1. Don the Air Mask following the instruction procedures.
These steps make up the Air Mask Functional Test.
2. If all steps are performed successfully, remove the Air
Mask and inspect it following the steps below.
3. Facepiece
a. Inspect the facepiece for rubber deterioration, dirt,
cracks, tears, holes, or tackiness.
b. Check the harness headstraps for breaks, loss of
elasticity,missing buckles or straps. Check the
straps for signs of wear.
c. Inspect the lens for cracks, scratches, and a tight
seal with the facepiece rubber.
d. The exhalation valve must be clean and operate
easily. The valve must move off the seat and return
when released.
e. Inspect the facepiece coupling for damage. Also
check to be surethe spider gasket, and valve disc
are present.
4. Cylinder and Remote Gauges
a. Be sure you can see both gauge needles and face
clearly through the lens. Also be surethe gauge
stem is not bent.
b. Inspect the gauge hose for any visible damage.
5. Whistle Audible Alarm
a. Check that the whistle is undamaged and clean.
6. Cylinder
Breathing apparatus cylinders should be recharged as
soon as possible after use. Cylinders should not be
stored partially charged for two reasons:
•If used without recharge, the service life of the
apparatus is reduced.
• The cylinder burst disc vents excess pressure if a
full cylinder is over exposed to fire or heat. If the
cylinder is not full, it may be damaged before the
burst disc vents.
It is also essential that the required inspections and tests
beperformed on all SCBA cylinders in accordance with
Department of Transportation (DOT) regulations. DOT reg-
ulations require that composite cylinders be retired from
service after the fifteenth year. Please note this does not
include cylinder valve assembly which may be reused.
Aluminum cylinder service life is indefinite if proper
inspection and hydrotest procedures are followed and
they indicate that the cylinder may remain in service.
Please contact your MSA distributor or sales associate if
you have questions or if you need additional information
regarding this policy.
Note: ANSI Z88.5 recommends checking cylinder pres-
sure weekly. For maximum safety the cylinders should be
stored full or empty (pressure above ambient but less than
100 psig).
a. If the cylinder is less than FULL, recharge it before
storing it. Cylinder air must be at least CGA Quality
Verification Level (Grade) D respirable air.
b. Inspect the cylinder valve for signs of damage. The
valve may be opened slightly to be sure it operates
properly.Be sure to fully close the valve.
c. Inspect the cylinder body for cracks, dents, weak-
ened areas, corrosive agent, causing the fibers to
break or peel, or signs of heat-related damage. If
the cylinder is damaged returnit to an MSA Service
Center. Call 1-800-MSA-2222 for instructions.
d. Check the hydrostatic test date on the cylinder
approval sticker located on the cylinder neck.
Fiberglass and Kevlar composite cylinders must be
tested every three years. Steel cylinders and carbon
fiber cylinders must be tested every five years.
8. Harness
a. Inspect all harness components for cuts, tears,
abrasion or signs of heat or chemically-related dam-
age.
9. Carrier
a. Inspect the cylinder strap and buckle to be sure it
holds the cylinder securely. Operate the over center
buckle to be surethat it opens and closes properly
and that it holds the cylinder securely.
b. Inspect back plate for cracks, weakened areas or
signs of heat or chemically related damages.
10. Record Keeping
Following inspection, the date and initials of the desig-
nated person should be recorded on an inspection
tag. A more detailed record of the operations per-
formed can be noted on an inspection and mainte-
nance log. Inspection tags and inspection and mainte-
nance logs are available from MSA. When the inspec-
tion data has been recorded, the breathing apparatus
is stored in a ready position.

FUNCTIONAL TESTS
FUNCTIONAL CHECKS
(AFTER EACH USE AND MONTHLY)
1. Check that the regulator works properly. The regulator
outlet should be sanitized before and after testing.
a. Check that the cylinder valve and buttons are
closed and that the system is not pressurized.
b. Gently inhale through the regulator outlet and hold
your breath for about 10 seconds. If the negative
pressure is maintained, there is no leakage.
c. Gently exhale through the regulator outlet for about
10 seconds. If the positive pressure is maintained,
there is no leakage.
d. Do not use the apparatus if airflow through the reg-
ulator is detected in either test. Return the regulator
to a certified repairperson.
2. Inspect the buttons and bypass valve.
a. With the regulator pressurized, operate each valve
to be sure it operates. Venting of pressure relief
valves (or a continuing flow of air through the regu-
lator when the user is not inhaling) indicates that the
regulator needs to be repaired.
b. Listen to the regulator. Any unusual sounds such as
whistling, chattering, clicking, or rattling mean that
the regulator should be checked further.
c. If any of these symptoms occur, the apparatus must
be removed from service. Return the regulator to a
certified repairperson.
3. Whistle Audible Alarm
a. Check that the function of the whistle audible warn-
ing device be checked by observing the regulator
gauge pressure at which the alarms sounds.
Performthis test with a minimum cylinder pressure
of 1,200 psig for the Low Pressure Air Mask, and
2,000 psig for the High Pressure Air Mask.
b. Pressurize the system by opening the cylinder valve
for a moment, then close it. The whistle must sound
indicating it is functioning.
c. Open bypass slowly.
d. Watch the drop in pressure on the shoulder gauge
and the point at which the whistle must begin to
sound. Nominal gauge readings at which the whistle
starts to sound are listed below.
550 psig approximately (low pressure system)
1125 psig approximately (high pressure system)
e. The whistle must continue until the air pressure is
approximately 200 psig or less. If the whistle does
not function properly, the apparatus must be
removed from service.
Do not disconnect the regulator coupling nut when
pressure is shown on the regulator gauge. Release all
pressure from the regulator by opening the bypass
valve. Removing the coupling nut with the regulator
pressurized may result in serious personal injury,
death, or damage to equipment.
f. Open the bypass valve slowly to release trapped air.
Close bypass valve.
g. Unscrew the regulator coupling nut from the cylin-
der valve. It is hand-tight and should not require
tools.
h. Inspect the coupling nut for thread damage. Also be
surethereis an O-ring and that it is not damaged.
i. Replace the O-ring if it is damaged.

WARNING

FLOW TEST AND OVERHAUL REQUIREMENTS
FLOW TEST AND OVERHAUL REQUIREMENTS
Your SCBA Regulator and whistle audible must be flow
tested and overhauled at specific time intervals. These
Maintenance Procedures must be performed by a trained
repairperson or at a Certified Service Center. Contact your
MSA sales representative or call the MSA Customer
Service Center at 1-800-MSA-2222. They will supply the
information you need to meet these requirements.
The required replacement/overhaul schedule for self-con-
tained breathing apparatus from MSA is based on appara-
tus usage on an individual basis. The frequency required
for SCBA overhaul depends upon how often the appara-
tus is used. MSA breathing apparatus must be overhauled
based on the actual level of usage, rather than on time
alone.
Overhaul is covered in the Regulator Disassembly and
Repair sections and includes installation of the Regulator
overhaul kits.
MSA breathing apparatus must be flow tested every year
using an MSA approved flow test device.
The following table summarizes MSA’s required frequency
for overhaul and flow testing.
Adecision to retire an Air Mask should be based on a
SCBA’s performance data and whether that data meets
the specified level of performance as defined in mainte-
nance requirements from MSA.
*The unit of SCBA use is defined as the consumption of
one 30 min. cylinder of air. Example: If three cylinders of
air are used, the SCBA would be considered to have been
used three times.If an assessment of a SCBA’s usage
cannot be estimated or determined, then the SCBA shall
be overhauled every three years.
