DESCRIPTION
FireHawk M7 Responder Air Masks from MSA are pres-
s
ure-demand, self-contained 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 complies with the National Fire Protection
Association (NFPA) Standard 1981 for Open-Circuit Self-
Contained Breathing Apparatus for Fire Fighters.
This air mask has been designated by NIOSH as being
CBRN (chemical, biological, radiological, and nuclear)
Agent Approved. It complies with the special tests under
NIOSH 42 CFR 84.63(c); Chemical Agent Permeation and
Penetration Resistance Against Distilled Sulfur Mustard
(HD) and Sarin (GB) and the Laboratory Respirator
Protection Level (LRPL) tests.
The FireHawk M7 Responder Air Mask consists of the fol-
lowing components.

OMPONENTS
PR14 FIRST STAGE REGULATOR
The PR14 First Stage Regulator reduces the pressure
f
rom the cylinder and valve assembly to an intermediate
pressure, which is in turn further reduced by the Firehawk
Responder Second Stage Regulator to a pressure that is
respirable by the user.
The PR14 First Stage Regulator incorporates a down-
stream design and dual springs.
The regulator incorporates a large, easily replaceable, sin-
tered filter to capture particulates that may be in the air
stream.
FIREHAWK RESPONDER SECOND STAGE
REGULATOR
The Firehawk Responder Regulator is a pressure-demand
regulator, which maintains a positive pressure in the face-
piece while the air mask is in use.
The Firehawk Responder Regulator attaches to the face-
piece via a push-to-connect feature.
The FireHawk Responder Regulator includes a pneumatic
plug that connects to the Ultra Elite Responder facepiece.
When the SCBA is pressurized, the pneumatic plug acti-
vates the pressure-demand exhalation valve.
The Firehawk Responder Regulator has a quick-connect
connection to the intermediate pressure hose.
CYLINDER AND VALVE ASSEMBLY
*As approved by NIOSH
The cylinder valve includes a metal valve body, threaded
connection for filling and attachment of the Audi-Larm
Alarm, handwheel, safety disc (burst disc), and pressure
gauge.
