SPECIFICA nONS General Requirements One ( or more) open circuit, self-contained breathing apparatus such as a Scott NxG2 200312, or equal, consisting of the following major sub-assemblies: (1) cylinder and valve assembly for storing breathing air under pressure; (2) full facepiece assembly; (3) an automatic dual path redundant pressure reducing regulator; (4) a removable, facepiece-mounted, positive pressure breathing regulator with air-saver switch, low-pressure alarm and purge valve; (5) a harness and bacldfame assembly for supporting the equipment on the body of the wearer; (6) a shoulder strap mounted, remote gauge indicating cylinder pressure; (7) a heads-up display (HUD) redundant low-pressure alarm; and (8) a rapid intervention crew/universal air connection (RICIUAC). The unit shall be covered by a warranty providing protection against defects in materials or workmanship. This warranty shall be for a period of eight years on the SCBA, except for the pressure reducer, which shall be covered for 15 years. Electronic components shall be warranted for three years. The SCBA shall be certified by NIOSH/MSHA as conforming to the Code of Federal Regulations, 42 CFR 84. This apparatus, without modification, shall be NIOSH/MSHA certified. The apparatus shall meet all requirements ofNFP A-1981 Standard on Open-Circuit, Self-Contained Breathing Apparatus, 2002 edition. The apparatus shall be CBRN approved. Successful bidder agrees to provide, at his own expense, a factory-trained instructor for such time as the department head shall require for complete instruction in the operation and maintenance of the apparatus. Any exceptions to these specifications must be detailed in a separate attachment, and failure to do so will automatically disqualify the bidder. Successful bidder must be a factory- authorized distributor to sell the equipment specified herein. Cylinder & Valve Assembly Type and Requirements Each cylinder valve such as a Scott 804721-01, or equal, shall consist of the following: (1) a hand activated valve mechanism with a spring-loaded, positive action, ratchet type safety lock and lock- out release for selecting "lock open service" or "non-lock open service"; (2) an upstream connected frangible disc safety relief device; (3) a dual reading pressure gauge indicating cylinder pressure at all times; (4) an elastomeric bumper; (5) an angled CGA inlet for charging; and (6) a tri-Iobe ergonomically designed hand-wheel. The Cylinder Valve shall be designed with a quick connect that delivers air directly to the first stage pressure-reducing regulator. The cylinder valve shall be offered with a CGA 346 or CGA 347 fitting for the purposes of filling the cylinder only. The fill fitting shall have a check valve to prevent flow from the cylinder. The fill fitting shall be provided with a dust cover to protect the threads from damage and prevent the interior surfaces from being contaminated when not in use. The dust cover shall have a means preventing air loss in the event the check valve fails. The dust cover shall be retained to the cylinder valve. The cylinder valve shall be a "fail open" type, constructed of forged aluminum and designed such
