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
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 regulator that is not identified as
a CBRN 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
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-pressure warning device, a potential safety
concern in 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.
