sprinkler system).

Ordnance Production Facilities.

Ordnance facilities used for manufacturing, maintaining, demilitarizing, handling,

processing, testing, servicing, and inspection of ammunition, explosives,

propellants and oxidizers or related devices containing these materials must

have complete automatic sprinkler protection and comply with DOD 6055.9-STD,

DOD Ammunition and Explosives Safety Standards. Requirements for IBC

Group H occupancies must be followed in the absence of specific guidance in

DOD 6055.9-STD and the individual service regulations based directly on DOD

6055.9-STD. The service regulations include:

For Navy projects, NAVSEA OP-5, Ammunition and Explosives Ashore Safety

Regulations for Handling, Storing, Production, Renovation, and Shipping.

For Army projects, Army AR 385-64, U.S Army Explosives Safety Program;

Army Pamphlet 385-64, U.S. Army Ammunition and Explosives Safety

Standards; and the Army Material Command Regulation 385-100, Safety

Manual.

For Air Force projects, Air Force AFMAN 91-201, Explosives Safety Standard.

6-10.1.1

Sprinkler Protection.

Automatic sprinkler systems in ordnance facilities must be provided with flexible

couplings and sway bracing similar to that provided for buildings in earthquake

zones. Complete automatic sprinkler protection is required for ordnance facilities

used for manufacturing, maintaining, demilitarizing, handling, processing, testing,

servicing, and inspection of ammunition, explosives, pyrotechnics, propellants,

and oxidizers or related devices containing these materials, unless such a

system will aggravate the hazard. The following guidelines for automatic

sprinkler protection must apply:

6-10.1.1.1 Where exposed thermally energetic materials are handled that

have a high probability of ignition, a large thermal output and a high probability of

causing personnel injury, operations must be protected using ultra high-speed

deluge systems. Ultra high-speed deluge systems have a response time of 100

milliseconds (ms) or less. Response time is measured from the time that an

energy source is presented to the detector to the time of initial water flow from

the critical nozzle, which is normally the nozzle closest to the hazard. Ultra high-

speed detectors usually consist of preprimed water delivery system, optical flame

detectors, and electronic controller. Paragraph 6-10.2 provides guidance on ultra

high-speed deluge systems. NFPA 15, Water Spray Fixed Systems for Fire
