What is Combustible?
A combustible substance is one capable of burning in oxygen to produce heat and light. In regulatory contexts, combustible liquids typically have flash points above 37.8°C (100°F), distinguishing them from flammable liquids with lower flash points. Combustion is an exothermic oxidation reaction; common combustible materials include organic compounds, many metals, and some inorganic compounds.

A combustible substance is one capable of burning in oxygen to produce heat and light. In regulatory contexts, combustible liquids typically have flash points above 37.8°C (100°F), distinguishing them from flammable liquids with lower flash points. Combustion is an exothermic oxidation reaction; common combustible materials include organic compounds, many metals, and some inorganic compounds.
Combustible materials are used as fuels (diesel, jet fuel, fuel oils), in industrial processes (combustible dusts in grain, coal, wood), and in thermite and pyrotechnic formulations. Controlled combustion drives heat engines, turbines, and power generation.
Combustible materials require proper storage (cool, well-ventilated, away from ignition sources), labelling, and handling procedures. Combustible dust explosions (grain silos, coal mines, flour mills) can be catastrophic. Use ATEX-rated equipment in combustible dust environments.
