66.9.16 Separation From Incompatible Materials

Except as provided for in 66.9.16.3, ignitible (flammable or combustible) liquids shall be separated from incompatible materials where the stored materials are in containers having a capacity of more than 5 lb (2.268 kg) or ¹/₂ gal (1.89 L). [30:9.17.1]

Separation shall be accomplished by one of the following methods:

1. Segregating incompatible materials storage by a distance of not less than 20 ft (6.1 m)
2. Isolating incompatible materials storage by a noncombustible partition extending not less than 18 in. (460 mm) above and to the sides of the stored materials
3. Storing liquid materials in Class I liquids [FP < 100°F (37.8°C)] storage cabinets in accordance with 66.9.4

[30:9.17.1.1]

Ignitible (flammable or combustible) liquids shall be separated from Level 2 and Level 3 aerosols in accordance with Chapter 61 and NFPA 30B. [30:9.17.2]

Liquids shall be separated from oxidizers by at least 25 ft (7.6 m). [30:9.17.3]

Materials that are water-reactive, as described in NFPA 704 shall not be stored in the same control area with ignitible (flammable or combustible) liquids. [30:9.17.4]
