6.5 Off-gassing. Materials to be installed in submarines are to be controlled to prevent off-gassing,
which contaminates the atmosphere and results in health hazards to personnel or deleterious effects on machinery.
These controls are accomplished through the Submarine Material Control Program, which is described in the
Nuclear Powered Submarine Atmosphere Control Manual, NAVSEA Technical Manual S9510-AB-ATM-010/(U).
Under the Submarine Material Control Program, all materials considered for use on submarines require
certification and assignment of a usage category. Under the certification process, candidate materials are selected
by Navy activities or contractors, and a request for certification is submitted to Commander, Naval Sea Systems
Command, ATTN: SEA 05Z9, 1333 Isaac Hull Ave., SE, Stop 5122, Washington Navy Yard DC 20376-5122. The
certification request is accompanied by detailed information, including descriptions of the material. A chemical
analysis is conducted, which is normally accomplished through off-gas testing. The off-gas test is required to be
conducted in a Government approved laboratory designated by the preparing activity. Information pertaining to this
test requirement may be obtained from Commander, Naval Sea Systems Command, ATTN: SEA 05Z9, 1333 Isaac
Hull Ave., SE, Stop 5160, Washington Navy Yard, DC 20376-5160. Based on the chemical analysis results, a
usage category is assigned to the material defining whether, and to what extent, the material may be used on
submarines.
6.6 Toxicity evaluation. The NAVENVIRHLTHCEN requires sufficient information to permit a HHA of
the product. Any questions concerning toxicity and requests for HHA should be addressed to the Commanding
Officer, Navy Environmental Health Center, ATTN: Hazardous Materials Department, Industrial Hygiene
Directorate, 620 John Paul Jones Circle, Suite 1100, Portsmouth, VA 20378-2103. Upon receipt of the HHA, a
copy should be provided to Commander, Naval Sea Systems Command, ATTN: SEA 05Z9, 1333 Isaac Hull Ave.,
SE, Stop 5133, Washington Navy Yard, DC 20376-5160.
