The document establishes mandatory packaging and preservation requirements for this aircraft component, with distinct specifications for two packaging levels. Level A packaging utilizes serviceable preservation method 41 and includes specifications for container dimensions (42 x 12 x 12 inches), cushioning materials per MIL-PRF-26514, barrier material per MIL-PRF-131, and appropriate labeling per IAW MIL-STD-129. Level B packaging uses preservation method 10 with ATA 300 Category I containment specifications and DOT-31FP compliance for compressed oxygen cylinders at pressures of 200 KPA (29 PSIG) or above. The document includes detailed bill of materials specifying container types, cushioning requirements, wrap materials, and filler specifications, with gross dimensions and weights provided for both levels.

The instruction document mandates critical handling and safety requirements including secure protection of the cylinder valve from damage and use of filler material to restrict movement in the cushion cavity if needed. The closure specifications differ between levels—Level A requires no specific closure while Level B specifies IAW ASTM-D 1974. Distribution is restricted to Department of Defense and U.S. DOD contractors for administrative or operational use only, with other requests referred to 406 SCMS/GULAA (Packaging Division), Tinker AFB, Oklahoma 73145. The document contains seven revisions dating from 1993 to 2018, with the most recent addressing mandatory container requirements and reestablishment of previous packing specifications.
