FSC 4240 INCH-POUND A-A-59783 25 October 2005 COMMERCIAL ITEM DESCRIPTION

3、SUPPLIED AIR RESPIRATOR WITH BACKUP SELF -CONTAINED BREATHING APPARATUS (SAR/SCBA) The General Services Administration has authorized the use of this commercial item description, for all federal agencies. 1. SCOPE. 1.1 Scope. This commercial item description covers the Supplied Air Respirator with a

4、 backup Self-Contained Breathing Apparatus (SAR/SCBA) for use in providing breathing air for entry into and escape from spaces aboard Navy ships where atmospheres are classified as being Immediately Dangerous to Life or Health (IDLH). The SAR/SCBA is primarily intended for use in Gas-Free Engineerin

5、g applications. This commercial item description does not cover the SAR external air source equipment. 2. SALIENT CHARACTERISTICS 2.1 Physical and performance characteristics. The SAR/SCBA shall operate in the pressure demand mode. The SAR/SCBA shall carry the approval and certification of the Natio

6、nal Institute for Occupational Safety and Health (NIOSH) for an open circuit, pressure demand, combination SAR and SCBA. The SAR/SCBA shall meet the NIOSH design, construction, and functional requirements in 42 CFR Chapter 84, subparts H & J. In the event of a conflict between this specification and

7、 the NIOSH requirements, the more restrictive requirement shall take precedence. The SAR/SCBA must be capable of satisfactory airline operation through a hose or multiple connected hoses with a minimum length of 250 feet between the external air supply source and the SAR. The required external air s

8、upply source pressure for the SAR shall not be greater than 125 pounds per square inch gauge (psig). In the event that the supplied air from the external air supply source is interrupted, the user shall be provided with the capability to readily switch to the backup SCBA located in an over-the-shoul

9、der mounted unit. 2.1.1 Facepiece. Each facepiece shall be a full mask and have an adjustable head harness. The facepiece shall permit the optional use of NIOSH approved corrective spectacles without compromising the protective features of the apparatus. The facepiece shall also be designed to minim

10、ize fogging of the eyepiece and spectacles. An adapter shall be provided with each facepiece to permit temporary attachment of an air breathing cartridge for use during fit testing of the facepiece in the negative pressure mode in accordance with Positive Pressure Respirators of ANSI Z88.2. The face

11、piece shall be fully immersible in a dilute solution (2 tablespoons per 1 gallons of water) of Wescodyne G or sodium hypochlorite, for the purpose of routine disinfecting and cleaning. 2.1.2 Second stage, low pressure regulator. A second stage, low pressure regulator shall be a pressure demand type

12、regulator and shall maintain a static positive pressure in the facepiece of not greater than 1.5 inches water gauge (w.g.). The pressure in the facepiece shall not fall below atmospheric during inhalation at air flow rates of less than 4 cubic feet per minute (cfm). An exhalation rate of 3 cfm shall

13、 not exceed the static pressure in the facepiece by more than 2 inches w.g. A don/doff switch/push button shall be provided on the second stage, low pressure regulator as a convenient means to start and stop the flow of breathing air to the facepiece when donning and doffing the facepiece. If any pa

14、rt of the second stage regulator is exposed to the exhalation path, the second stage regulator shall be fully immersible in dilute solution (2 tablespoons per 1 gallons of water) of Wescodyne G or sodium hypochlorite for the purpose of routine cleaning and disinfecting.

The SAR/SCBA shall be equipped with two 75-foot length

16、s of breathing air line hose to connect the SAR/SCBA to the external air supply. The working pressure of the air line hoses connecting to the external air supply source shall be rated for at least 125 psig. All external air supply hoses shall be fitted with quick-connect fittings consisting of Foste

17、r type SL 3003 W “Safety Lock“ quick-connect female couplings and Foster type 11-3S/S stainless steel male coupling plugs to interface with the Navys supplied air systems. Separate breathing air hoses shall be supplied to connect the facepiece to the backup SCBA air supply. Hoses shall be tested to

18、twice working pressure and have a permanently attached tag with the test pressure and test date. 2.1.4 Backup SCBA. The backup SCBA shall be rated by NIOSH as providing a 15-minute service life of breathing air. The backup SCBA shall meet the service life requirement after stored for 6 months in the

19、 environmental conditions specified in 2.1.8 without being replenished. 2.1.4.1 Backup SCBA assembly. The backup SCBA assembly shall be made from a durable fabric/material and shall have adequate construction to protect the composite air cylinder(s) from being scratched or otherwise damaged when the

20、 fully loaded unit is slid across the flat edge of a steel angle or channel. The wearable weight of the fully loaded unit (including straps/belts) shall not exceed 13.0 pounds. The backup SCBA unit shall be designed with a shoulder strap to allow it to be carried over the shoulder and shall contain

21、the backup SCBA air cylinder(s), the backup SCBA cylinder pressure regulator(s), the backup SCBA pressure indication device, the backup SCBA low pressure alarm, and the backup SCBA air supply control valve(s). The backup SCBA unit shall also include a waist belt to fasten the unit to the body of the

22、 user. The shoulder strap and waist belt shall be constructed of a nylon fabric and shall be at least 2 inches wide. 2.1.4.2 Backup SCBA air cylinder(s). The backup SCBA air cylinder(s) shall be fully wound fiber-wrapped composite construction and certified under current requirements established by

23、the Department of Transportation (DOT), and shall be rated for a breathing air working pressure not greater than 4500 psig. Cylinders shall be delivered fully charged with Type 1, Grade D quality air in accordance with CGA G-7.1 and with a maximum mois ture content of 20 mg/m3 or a dew point less th
