Class B - Flammable and Combustible Materials
Examples of flammable liquids are
- Flammable and combustible indicate the ability of a material to ignite and burn readily.
- The term flammable liquid is used for materials having a flashpoint of less than 37.8 C (100 F) under test conditions.
- The flashpoint is the minimum ambient temperature at which a liquid gives off enough vapour in sufficient concentration to ignite.
- The flashpoint indicates how easily a material will ignite and burn.
- A liquid is called a combustible liquid when it has a flashpoint of 37.8 C (100 F) or more but less than 93.3 C (200 F).
- Generally combustible materials are less easily ignited then flammable materials and require somewhat higher temperatures than flammable materials before they start to burn.
- Flammable and combustible materials could be gases, liquids or aerosols.
Examples of Combustible liquids are
- benzene, turpentine, gasoline, etc.
- Kerosene, carbolic acid, naphthalene, etc.
