Flammable liquids

All flammable liquids are volatile by nature, but it’s the liquid’s vapours (combined with air), rather than the liquid itself, that ignite and burn. The rate of evaporation varies from one liquid to another and increases with temperature. Increased temperature also increases vapour production—this creates a more hazardous condition.

Preventive fire safety precautions will be covered in Competency A-5 “Describe Fire Safety.”
