Spontaneous combustion flammable solids

Liquids and solids do not burn as such, but on exposure to heat vaporize or undergo thermal degradation to liberate flammable gases and vapours which burn. Some chemicals undergo spontaneous combustion (see page 214).

DOT CLASSIFICATION 4.2 Label Spontaneously Combustible SAFETY PROFILE A flammable solid. See also CHARCOAL (BRIQUETTES). 

DOT CLASSIFICATION 4.3 Label Dangerous When Wet (UN 2950) DOT Class 4.1 Label Flammable Solid (UN 1869) DOT Class 4.3 Label Danger When Wet, Spontaneously Combustible SAFETY PROFILE Inhalation of dust and fumes can cause metal fume fever. The powdered metal ignites readily on the skin causing burns. Particles embedded in the skin can produce gaseous blebs that heal slowly. 

ACGIH TLV TWA 2 mg(Al)/m3 SAFETY PROFILE A flammable solid. Danger from spontaneous combustion. When heated to decomposition it emits toxic fumes of Br . 

DOT CLASSIFICATION 4.2 Label Spontaneously Combustible (UN 1382) DOT Class 8 Label Corrosive (UN 1847) SAFETY PROFILE Poison by ingestion and inhalation. Emits H2S in contact with acids steam. A flammable solid. Unstable may explode on percussion or rapid heating. Ignites on contact with nitrogen oxide. Reacts with H2O to form KOH and KSH. When heated to decomposition it emits very... 

ALPEROX C (105-74-8) A flammable solid (flash point <127°F/<53°C). A powerful oxidizer and organic peroxide. Violent reaction with reducing agents, organic matter, thiocyanates. May ignite or explode spontaneously when heated, on contact with hot surfaces, when mixed with combustible materials, or otherwise contaminated. Shock- or friction-sensitive when heated. 

IXPER 25M (14452-57-4) Flammable solid. Dust or powder forms explosive mixture with air. Contact with moisture causes the release of oxygen and heat may ignite spontaneously. A powerful oxidizer. Violent reaetion or decomposition with reducing agents, catalysts, ethers, thiocyanates. Dangerous fire risk with acidic and combustible materials. May be shock- and/or heat-sensitive explosive.
