Consolidated Requirements

4.3.15.4 The maximum amount of Class I, II, and IIIA

NFPA 45, 2.2.1.3

flammable and combustible liquids that can be stored in

a laboratory fire area is 400 gallons of which the

maximum amount of Class I flammable liquids is 300

gallons.

4.3.16 Sites for outdoor storage lockers (see definition) shall be

NFPA 30, 4.6.4

reviewed to ensure proper placement, separation, etc.

4.3.16.1 Multiple outdoor storage lockers at a given site shall be

NFPA 30, 4.6.4

separated according to requirements in NFPA 30.

4.3.16.2 In outdoor storage lockers, containers in their original

NFPA 30, 4.6.4.4.1

shipping packages shall be permitted to be stored either

on pallets or in piles, while unpacked containers shall

be stored on shelves or on the floor.

4.3.16.3 No other flammable or combustible materials shall be

NFPA 30, 4.6.4.4.2

stored at designated outdoor storage locker sites.

4.3.16.4 Outdoor storage lockers shall be placarded according to

NFPA 30, 4.6.4.4.3;

NFPA 704.

NFPA 704

4.4 Oxidizers

[NOTE: Additional requirements can be found in NFPA 430, "Code for

Storage of Solid and Liquid Oxidizers", when quantities exceed 4,000

pounds of Class 1 oxidizer (see definition), 1,000 pounds of Class 2

Oxidizer (see definition), 200 pounds of Class 3 Oxidizer (see

definition), or 10 pounds of Class 4 Oxidizer (see definition). Oxidizer

classes are defined in NFPA 430".]

4.4.1 Oxidizer storage areas shall be conspicuously identified with the

NFPA 430, 2.2.1

words "Class (appropriate classification number) Oxidizers."

4.4.1.1 Areas used to store oxidizers of different classes shall be

NFPA 430, 2.2.2

marked as containing the most severe hazard.

4.4.2

Water based manual fire fighting equipment shall be used in

NFPA 430, 2.11.6

oxidizer storage areas.26

Oxidizer storage areas and flammable liquids storage areas require water- based fire suppression systems. While

there are no requirements to keep water reactive materials away from oxidizers, when storing oxidizers,

consideration should be given to the additional hazard posed by the presence of water reactive materials when water

suppression systems are activated.
