DESCRIPTIONDESCRIPTIONFireHawk M7 Air Masks from MSA are pressure-demand,self-contained breathing apparatus (SCBA) certified by theNational Institute for Occupational Safety and Health(NIOSH) for use in atmospheres immediately dangerous tolife or health:``Immediately dangerous to life or health’’ means conditionsthat pose an immediate threat to life or health orconditions that pose an immediate threat of severe exposureto contaminants, such as radioactive materials,which are likely to have adverse cumulative or delayedeffects on health [Title 42 CFR, Part 84.2, (Q)].This Air Mask complies with the National Fire ProtectionAssociation (NFPA) Standard 1981 for Open-Circuit Self-Contained Breathing Apparatus for Fire FightersThis Air Mask has been designated by NIOSH as beingCBRN (chemical, biological, radiological, and nuclear)Agent Approved. It complies with the special tests underNIOSH 42 CFR 84.63(c); Chemical Agent Permeation andPenetration Resistance Against Distilled Sulfur Mustard(HD) and Sarin (GB) and the Laboratory RespiratorProtection Level (LRPL) tests.The FireHawk M7 Air Mask consists of the followingcomponents.• PR14 First Stage Regulator• Firehawk Second Stage Regulator• Cylinder and Valve Assembly• Audi-Larm Audible Alarm with URC Assembly• FireHawk M7 Carrier and Harness Assembly• Ultra Elite ® Facepiece• FireHawk M7 HUD• FireHawk M7 Control Module• FireHawk M7 Power ModuleOptional FIREHAWK M7 AIR MASK COMPONENTS• Clear Command ® Communications System• FireHawk M7 Telemetry Module• ExtendAire System• Quick-Fill System• Rescue BeltFIREHAWK M7 AIR MASK COMPONENTSPR14 FIRST STAGE REGULATORThe PR14 First Stage Regulator reduces the pressurefrom the cylinder and valve assembly to an intermediatepressure, which is in turn further reduced by the FirehawkSecond Stage Regulator to a pressure that is respirableby the user.The PR14 First Stage Regulator incorporates a downstreamdesign and dual springs.The regulator incorporates a large, easily replaceable, sinteredfilter to capture particulates that may be in the airstream.FIREHAWK SECOND STAGE REGULATORThe Firehawk Regulator is a pressure-demand regulator,which maintains a positive pressure in the facepiece whilethe air mask is in use.The Firehawk Regulator attaches to the facepiece via aslide-to-connect or a push-to-connect feature.The Firehawk Regulator has two available covers, purgeand hard cover. The purge cover offers the user the abilityto manually activate the regulator or to provide a quickburst of air during use without using the bypass knob.There are also two types of Firehawk Regulator intermediatepressure hose connections, threaded and quick-connect.CYLINDER AND VALVE ASSEMBLYCapacity Pressure Rated Svc*Cubic Ft. psig Life (Min.)45 4500 3088 4500 6045 2216 3045 2216 3060 3000 3066 4500 45*as approved by NIOSHThe cylinder valve includes a metal valve body, threadedconnection for filling and attachment of the Audi-LarmAlarm, handwheel, safety disc (burst disc), and pressuregauge.The pressure gauge continuously shows the air pressurein the cylinder.The handwheel is used to open and close the cylindervalve.5 TAL 806 (L) Rev. 3 - 10082858
