Flammable solids

The Cst for a flammable solid may also be calciilated. For sugar, whose molecular weight is 342, Cjt is calculated as follows ... 

While this book does not cover shock-sensitive powders, such as primary explosives, UN-DOT Class 4.1 Flammable Solids are within its scope. These include thermally unstable powders that can both deflagrate in an oxidant and decompose in bulk. Examples include some nitrogen blowing agents. Should ignition occur at any point, a propagating decomposition...

Hazard Class A series of nine descriptive terms that have been established by the UN Committee of Experts to categorize the hazardous nature of chemical, physical, and biological materials. These categories are flammable liquids, flammable solids, explosives, gases, oxidizers, radioactive materials, corrosives, poisonous and infectious substances, and dangerous substances. 

NFPA 325, Fire Hazard Properties of Flammable Liquids, Gases, and Volatile Solids, gives NFPA Instability Ratings and indications of water reactivity for flammable liquids, flammable gases, and volatile flammable solids.

Although the transport of dry lead picrate is forbidden by the Department of Transportation (DOT) (49 CFR 172.101), the addition of water desensitizes it. No hazard classification is available from DOT for wetted lead picrate, but silver picrate, which is similar in sensitivity, may not be shipped when dry but is classified as a flammable solid (Hazard Class/Division 4.1) when it is wetted with water by at least 30 percent by mass. 

A flammable solid is a solid that can ignite from friction or from heat remaining from its manufacture, or which may cause a serious hazard if ignited. Explosive materials are not included in this classification.

Multipurpose dry chemical extinguishers (20-A 80B-C) should be provided in warehouses and shop buildings where wood, paper, plastics, and other flammable solids, as well as flammable liquids, may be stored. In grease manufacturing and compounding or similar operations where little or no wood, paper, and similar combustibles are stored, but where flammable liquids may be prevalent, potassium bicarbonate dry chemical extinguishers should be used. Extinguishers should be located not more than 75 ft (23 m) away from any potential Class A fire hazard and not more than 50 ft (15 m) from Class B fire hazards.
