Consolidated Requirements

4.4.2.1 The placement and use of dry chemical extinguishers

NFPA 430, 2.11.6.1

containing ammonium compounds (Class ABC) shall be

prohibited in oxidizer storage areas where oxidizers that

can release chlorine are stored.

4.4.2.2 Halon extinguishers shall not be used in oxidizer storage

NFPA 430, 2.11.6.2

areas.

4.4.3 Combustible construction materials that could come into contact

NFPA 430, 2.12

with oxidizers shall be coated with a compatible material to

prevent their impregnation with the oxidizers.

4.4.4 Absorptive packing materials, wooden pallets, etc., that are

NFPA 430, 2.13.5

exposed to water containing oxidizers or that contain water

soluble oxidizers, and are exposed to water shall be immediately

relocated to a safe outside area and properly disposed of.

4.4.5

Oxidizers shall not be stored where they can be heated to within

NFPA 430, 2.8.1

25F of their decomposition temperature or above 120F,

whichever is lower.27

4.5 Organic Peroxides

4.5.1 Chemical storage areas used for the storage of organic peroxides

NFPA 432, 4.1

shall be conspicuously identified with the words "Organic

Peroxides" and by the class.

4.5.1.1 Areas used to store organic peroxides of different classes

NFPA 432, 4.1.1

per NFPA 432, shall be marked as containing the most

severe hazard.

4.5.1.2 Packages containing organic peroxide formulations shall

NFPA 432, 4.1.2

be individually marked with chemical name and other

pertinent information to allow proper classification.

4.5.1.3 Packages of organic peroxides that require temperature

NFPA 432, 4.1.3

control shall be marked with the recommended storage

range.

4.5.2 A clear space of at least 2 ft. shall be maintained between organic

NFPA 432, 4.11.2

peroxide storage and uninsulated metal walls.

Attention should be used to ensure that oxidizers stored in direct sunlight are not heated above allowed

temperatures by radiant heating.
