the same manner as Class IIIA combustible liquids in accordance with NFPA 30.
A single building is often used for storage of both flammable and combustible
liquids and hazardous materials. Requirements for the storage of hazardous
waste are separate and distinct from the storage of hazardous materials.
Note: For Navy facilities used to store hazardous materials, also
refer to MIL-HDBK-1032/2, Covered Storage. For Navy and Air Force facilities
used to store hazardous waste, also refer to MIL-HDBK-1005/13, Hazardous
Waste Storage Facilities.
6-11.1.1
Warehouse Areas for Storage of Flammable Liquids, Solids,
and Hazardous Materials. Warehouse areas for storage of flammable liquids,
solids, and hazardous materials and chemicals must not exceed 1,858 m2
(20,000 ft2) between firewalls and travel distance must not be more than 23 m
(75 ft) (30.5 m (100 ft) if sprinklered) to the nearest fire exit. Firewalls must have
a minimum 4-hour rating. Ceiling height must not exceed 9.1 m (30 ft).
6-11.2
Flammable and Combustible Liquid Storage Areas. Provide
automatic sprinkler protection. Ceiling and in-rack sprinklers must be designed in
accordance with and NFPA 30 and installed in accordance with NFPA 13.
Aqueous film-forming foam (AFFF) systems may be used where permitted by
NFPA 30. The following minimum criteria must apply:
Provide a minimum longitudinal flue space of 305 mm (12 in)
between double row racks and 230 mm (9 in) between single row
racks and the wall.
Provide ceiling level sprinklers and in-rack sprinklers. The in-rack
sprinklers must protect the longitudinal flue space and must be
located at every level of rack storage.
Exception: Where multiple levels of rack storage are used below
the 1.83 m (96 ft) level for hand picking operations, provide one extra row of in-
rack sprinklers in the longitudinal flue space at the 0.914 m (3 ft) level. The first
level of storage must not be a minimum of 305 mm (1 ft) above the finished floor
level to facilitate easier cleanup of spills.
6-11.3
Hazardous Materials Storage Areas. Provide a minimum of 2-
hour fire rated construction between hazardous materials storage areas and
those used for storage of flammable and combustible liquids. These areas must
be labeled as "Hazardous Materials Only," and must also be labeled as to the
type of sprinkler protection present in each room. Provide automatic sprinklers at
the ceiling level as well as one mandatory level of in-rack sprinklers (i.e., in the
flue space between the rack and the wall) located at or slightly above the
midpoint with respect to overall storage height. In hazardous material storage
areas not containing flammable or combustible liquids, design ceiling sprinkler
densities based on the storage of Class IV commodities in NFPA 13. In water
