A-A-58019 Self Generating Nitrogen Servicing Cart \(Sgnsc\)This CID covers a SGNSC which can be towed over unimproved surfaces and transported by helicopter and fixed wing aircraft. It will be used to produce 95 percent pure nitrogen gas at 5000 pounds per square inch gage \(peig\) at a rate of 1511 standard cubic feet per minute \(acfn\) . The nitrogen gas will be used to service tires, struts, accumulators, and to fill external receivers. A bid sample test is required of the offerer. This CID contains Appendix A, Bid Sample Test Requirements; Appendix B, Bid Sample Test Report Requirements; and Appendix C, Certificate Format.

Safety Assessment

Task 101. All of Paragraph 4, General Requirements, is applicable. Satisfactory hazard control

shall be reduction to a combined seventy- probability of IE, IID, IIIC, IVB or less IAW MIL-

STD-882. Hardware configuration shall meet the criteria of MIL-STD-454M, Requirement 1 and

MIL-STD-1472D, Para 5.4, 5.9 and 5.13. Identified hazards related to electrical shock shall

specify the frequency, current and voltage ratings of the exposure. As a minimum. the fault hazard

analysis technique or equivalent shall be used to develop system safety data.

Task 107. The analysis shall summarize open and newly-identified hazards, modifications, safety-

related engineering change proposals, and changes in risks of hazards. Program activities that

impact system safety shall also be evaluated (DU-SAFT-80105A/T).

Task 301, The Contractor shall summarize hazards and corrective actions pertaining to design

safety features, energy sources, transportation, operations, material handling and maintenance.

Use of a hazard risk index after each corrective action is required (DI-SAFT-80102A/T).

Technical Orders. The Contractor shall ensure that Air Force Occupational Safety & Health

standards and other applicable safety standards are addressed in all publications. All manuals shall

comply with the safety requirements in MIL-M-38784C.

16. Automatic Unloader.

a. The SGNSC shall provide for high pressure nitrogen gas output at a range from 350 to

5000 psig and low pressure nitrogen gas output at a range from 0 to 350 psig with low and high

pressure output hoses arid connections at or near the operators panel.

b. The SGNSC shall be fully automatic once the nitrogen system is engaged by the

operator and shall remain automatic until the nitrogen system is disengaged by the operator.
