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 air mask, when equipped with the Ultra Elite Hycar
facepiece and CBRN regulator, is considered “CBRN
hardened” for applications when NIOSH approval for use
against these live agents is not required. This air mask
has been tested and passed the NIOSH CBRN (chemical,
biological, radiological, and nuclear) live agent test
requirements.
• This SCBA is not compliant with U.S. National Fire
Protection Association (NFPA) Standard 1981. Do
NOT use this SCBA for firefighting applications
whereNFPAcompliance 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 regulator that is not identified as
aCBRN regulator against CBRN live agents.
Failure to follow these warnings can result in serious
personal injury or death.
BlackHawk MMR breathing apparatus consists of the fol-
lowing major sub-assemblies.
•first stage regulator
• second stage regulator
•air cylinder and valve
• NightFighter Heads-Up Display System
• 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 80psig throughout the entire
operating pressure range of the cylinder. 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.
Blackhawk SCBA with the Firehawk MMR model numbers
10060982 and 10060983 are considered by MSA to be
“CBRN hardened”. They can be identified by the Firehawk
Regulator model number and the CBRN marking on the
underside of the regulator housing. SCBA with these reg-
ulator model numbers have passed CBRN live agent test-
ing, but are not CBRN-approved by NIOSH, since they are
not certified as NFPA compliant. MSA has chosen not to
seek NFPA compliance due to the requirement for a
redundant low-pressurewarning device, a potential safety
concernin revealing the position of the user during tacti-
cal operations.
AIR CYLINDER AND VALVE
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 100psig increments. For example, a
gauge reading of 20 is read as 20 x 100 or 2,000psig. A
handwheel is used to open and close the cylinder valve.
*as approved by NIOSH
QUICK-FILL SYSTEM (OPTIONAL)
The Quick-Fill System is a shoulder mounted male quick-
fill inlet for 2216psig emergency filling of SCBA. Also
included with the 2216psig Quick-Fill System is a pres-
sure relief valve for protection of the cylinder burst disc.
The Quick-Fill System may also be used for transfill oper-
ations.

DESCRIPTION
CARRIER AND HARNESS
The carrier consists of a backplate, a shroud to cover the
cylinder and first stage regulator, 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. 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 contaminants out of
the mask mounted regulator.The facepiece has a speak-
ing diaphragm for clear,shortrange communication.
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.

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. Failure to fol-
low this precaution can result in serious personal
injury or death.
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 facepiece.
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 NFPA-1500 and ANSI Z88.2). An
improper facial seal may allow contaminants to leak
into the facepiece, 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.
3. Open the cylinder valve
fully.

REMOVING THE APPARATUS
SAFETY PRECAUTIONS FOR MSA SELF-CONTAINED
BREATHING APPARATUS CYLINDERS
Breathing apparatus cylinders should be fully recharged
as soon as practicable after use. Cylinders should not be
stored partially charged for two reasons:
1.If used partially charged, the duration of the apparatus
isreduced.
2. The pressure relief device is only designed to protect
afully 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 100psig. Prior
to recharged, cylinders must be examined externally for
evidence of high heat exposure, corrosion, or other evi-
dence 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: "Standards for
Visual Inspection of Steel Compressed Gas Cylinders",
CGA Publication C-6.1: "Standards for Visual Inspection
of High Pressure Aluminum Compressed Gas Cylinders",
and/or CGA Publication C-6.2: "Guidelines for Visual
inspection and Requalification of Fiber Reinforced High
Pressure Cylinders" available form the Compressed Gas
Association, Inc., 1725 Jefferson Davis Highway, Suite
1004, Arlington, VA22202-4102.
If thereis any doubt about the suitability of the cylinder
for recharge, it should be returned to a certified hydrostat-
ic test facility for expertexamination and testing.
Always check to be sure the retest date is within the pre-
scribed 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.
Establish the 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., DOT-E-
#####), the exemption should be consulted and is avail-
able 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.
Appropriately connect the cylinder to the filling system
and refill. Terminate the filling when the pressure reaches
the service pressure and allow the cylinder to cool to
room temperature. If necessary, top-off the cylinder such
that the service pressure is attained with the cylinder at a
temperature of 70°F. Close the valves on the cylinder and
the filling system and remove the cylinder. Apply a leak
solution to determine if there is any leakage between the
cylinder and the valve. If there is no leakage, the cylinder
is ready for 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 attack any
part of the apparatus, causing the apparatus NOT to per-
form as 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. Failure to follow this precaution may result in
serious personal injury or death.

QUICK-FILL SYSTEM OPERATION
QUICK-FILL SYSTEM OPERATION
The Quick-Fill is a male quick-fill inlet for use by Rapid
Intervention Crews for emergency filling operations. The
2216psig system also includes an automatically-resetting
pressure relief valve.
Note: The Quick-Fill may be used for transfill operations
asdescribed in this manual. Standard operating proce-
dures should be developed for use of Quick-Fill System.
The Quick-Fill System 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 trans-
filling air ONLY if appropriate Quick-Fill hose assemblies
from MSA are used. Quick-Fill hose assemblies and fittings
are rated for a maximum working pressure of 4500psig.
For transfilling operations using the Quick-Fill System,
do not use any transfilling hose assembly or fittings
other than those supplied by MSA specifically for the
Quick-Fill System. Use of any other transfilling hose
assembly and/or fitting may result in serious personal
injuryor death, and will void NIOSH approval.
Do not lubricate the Quick-Fill fittings. Do not permit
oil, grease, or other contaminants to come in contact
with the Quick-Fill fittings. The Quick-Fill hose assem-
blies 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 SOURCE
Asecondary air source stores compressed breathing air
until needed to refill SCBA air cylinders. Secondary air
source pressure must be greater than air mask cylinder
pressure. Examples of air sources include: Cascade air
cylinder refilling systems; high pressurecompressor sys-
tems with a fixed reservoir; and an SCBA air cylinder
which is not installed on an SCBA.
Do not connect a Quick-Fill System equipped Low
Pressure SCBA to an unregulated secondary air
source with a pressure greater than 2216psig. The
Quick-Fill System equipped low pressureair mask is
rated for a maximum working pressure of 2216psig. As
an additional safety feature, the SCBA has a pressure
relief valve which automatically vents at 2500psig. Do
not connect a High PressureSCBA to a secondaryair
source with a pressure greater than 4500psig. The
high pressure air mask is rated for a maximum work-
ing pressure of 4500psig.
Failure to follow the above warnings may result in
serious personal injury or death.
The user is responsible for the air source, which must
meet the requirements of Compressed Gas Association
Specification ANSI/G-7.1, Quality Verification Level
(Grade) D Gaseous Air or better, with a moisture dew
point of not greater than -65°F (24ppm water vapor, nor-
mal). Pressures at the inlet of the Quick-Fill System hose
must not exceed that of the SCBA (2216psig or
4500psig). The user also is responsible for connecting the
Quick-Fill hose to an appropriate secondary air source.
1. To connect the Quick-Fill System hose to Quick-Fill
System fitting installed on the air source):
a. Push the female fitting on the male fitting until it
snaps in place. Pull on the hose to be sure the fit-
ting snapped into place.
b. Turn the air source on.
If there are leaks from either female fitting, or along
the hose, depressurize the hose and correct the prob-
lem. Such leakage can result in increased fill time.
2. To attach the Quick-Fill System hose to the SCBA:
a. Remove the rubber dust cap from the male inlet fit-
ting on the SCBA. Be surethat the cylinder valve is
fully opened.
Note: The shut-off button may be either open or closed,
depending on whether the SCBA is donned.
b. Remove the rubber dust cap from the female fitting
on the Quick-Fill System hose.
c. Push the female fitting on the male fitting until it
snaps in place. Pull on the hose to be sure the fit-
ting snapped into place. Transfilling begins when
the female fitting is snapped on the SCBA.
Note: If the secondary air source does not have a suffi-
cient volume of air, the SCBA cylinder will not reach full
service pressure. After approximately 45-60 seconds,
pressure between the secondary air source and the SCBA
cylinder will be equal.
Cylinder temperature will increase by approximately
45°F
.The pressure gauge may show FULL immediately
after transfilling, but cylinder pressure may decrease
by as much as 190psig after the cylinder cools to
room temperature. Actual service time may be
reduced accordingly.
3. Compare the SCBA pressure gauge reading to the
secondaryair source pressure gauge reading. If the
readings are the same, pressure is equal.
4. Todisconnect the Quick-Fill System hose after trans-
filling, pull the gray sleeve back. The hose fitting and

the SCBA will separate. A hiss or pop may be heard
as the fittings separate and the high-pressure air is
sealed off.
5. Immediately install the dust cover on the SCBA male
fitting.
6. The SCBA cylinder is ready for service if the cylinder
pressure gauge is on the corresponding color band.
EMERGENCY OPERATIONS
1. If you are transfilling in fresh air and the dust cover will
not stay on the SCBA male fitting because air is leak-
ing, correct the condition before using the SCBA.
2. If you are transfilling in a contaminated atmosphere
and the dust cover will not stay on the SCBA male fit-
ting because air is leaking:
a. Immediately reconnect the Quick-Fill System hose
to seal off the leak and return to fresh air.
b. If you cannot reconnect the hose, reach behind and
close the cylinder valve. Air pressure in the regulator
will drop, and the leak will slow down.
c. Quickly replace the protective dust cap on the
SCBA male regulator fitting. This will form a redun-
dant seal.
d. Open the cylinder valve and returnto fresh air
immediately. The dust cover prevents dirt, water,
and debris from entering the fitting, and acts as a
redundant seal.
TRANSFILLING BETWEEN SCBA FROM MSA
(EMERGENCY BREATHING SYSTEM)
Note: The SCBA with the higher pressure reading is the
donor. The SCBA with the lower pressure is the receiver.
Transfilling between users of SCBA 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.
Do not transfill if the donor's NightFighter Heads-Up
Display System is flashing. Failure to follow this warn-
ing may result in shorter escape time to return to fresh
air,causing serious personal injuryor death.
NIGHTFIGHTER HEADS-UP DISPLAY SYSTEM
RECEIVER PRESSURE READING
The NightFighter Heads-Up Display System Red LED
begins flashing to indicate that the pressure in the cylinder
has been reduced to 25% of its rated working pressure.
Remaining service time must be used for escape to fresh
air. If the donor's NightFighter Heads-Up Display System
Red LED begins flashing during transfilling, the donor
should disconnect and preserve his escape time.
1. If the donor's NightFighter Heads-Up Display System
is not flashing and you have sufficient air to transfill air
to a receiver, (greater than1000psig for Low Pressure
SCBA and greater than 2000psig for High Pressure
SCBA), follow these steps.
a. Remove the 3 foot emergency transfill hose from its
protective pouch.
b. Remove the rubber dust cover from both female fit-
tings on the Quick-Fill System hose assembly.
c. Remove the rubber dust cover from the male quick-
fill fitting.
d. 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.
If serious leakage is noticed from either of the two
female fittings, or anywhere along the hose, discon-
nect the female fittings and return to fresh air immedi-
ately.Failureto follow this warning may result in seri-
ous personal injury or death.
e. After approximately 30-60 seconds, pressure
between the SCBA cylinders will be equal.
f. Disconnect the Quick-Fill System hose from both
SCBA by pulling the gray sleeve back on both ends.
Ahiss or pop may be heardas the fittings separate
and the high pressure air is sealed off.
g. Immediately install the dust cover on the quick-fill
male fitting. The dust cover prevents dirt, water, and
debris from entering the fitting, and acts as a redun-
dant seal.
EMERGENCY OPERATIONS
1. If the dust cover will not stay on the SCBA or Quick-
Fill male fitting because air is leaking:
a. Immediately reconnect the Quick-Fill System hose
to seal off the leak and return to fresh air.
b. If you can not reconnect the hose, reach behind
and close the cylinder valve. Air pressure in the reg-
ulator will drop, and the leak will slow down.
c. Quickly replace the protective dust cap on the
SCBA male fitting. This will formaredundant seal.
d. Open the cylinder valve and return to fresh air
immediately.
2. Preparing the Quick-Fill System for Storage:
a. Press in on the center of the quick-disconnect dust
cap to release any pressure in the Quick-Fill System
hose.

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 air flow.
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 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 sure the 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
