MIL-HDBK-1032/2
Containment. Use grate-covered interior 350 gallon (1323 L) sumps
4.5.4
in conjunction with the trench system to provide spill or leakage containment
for the lesser of 1,000 gallons (3785 L) or 10 percent of the total free
flowing liquid volume of all containers stored in each room. Provide a
containment capacity of 1,000 gallons (3785 L) at the truck apron adjacent to
the shipping and receiving area. Include a controlled flow system to prevent
spilled or leaking materials from entering the storm drainage system, stream,
or body of water.
4.5.5
Drainage. Install pallet racks and associated mechanical vehicle
guidance systems so as to permit the unimpeded flow of spilled liquids to
collecting trenches. Maintain floor flatness requirements. Floor drains
shall not be installed in the storage areas of flammable/hazardous warehouses.
4.6
Automatic Fire Suppression Systems. Provide all areas with
automatic fire suppression systems.
4.6.1
Design Requirements. System design shall comply with the
requirements of MIL-HDBK-1008; Low Expansion Foam and Combined Agent Systems,
NFPA 11; NFPA 12; NFPA 13; NFPA 30; NFPA 231; NFPA 231C; and 29CFR Part 1910.
Water demand for sprinklers shall be based on hydraulic design of the system.
Sprinkler heads shall be suitable for installation in a corrosive
environment. Storage areas for water reactive materials shall be protected by
a bromotrifluoromethane (Halon 1301) or carbon dioxide fire extinguishing
system. Where nonwater systems are used, provide a 30-second audible warning
prior to system activation. Provide automatic local fire department signaling
upon system activation.
4.6.2
Sprinkler Adjustment. Provide adjustment of sprinkler positioning
through use of mechanical grooved piping rather than threaded pipe fittings,
as illustrated in Figure 21. Contact the Navy Warehouse Utilization Program
at NAVSUP for guidance in specific applications.
