Combustible Liquids

Definition - What does Combustible Liquids mean?

OSHA defines a combustible liquid used in the construction industry as a liquid having a flash point of 140 degrees Fahrenheit or more. The upper limit for combustable liquids is a flashpoint of 199 degrees Fahrenheit. For other industries, a combustible liquid will have a flash point of 100 degrees Fahrenheit or more.

Safeopedia explains Combustible Liquids

A flash point is the the temperature at which fumes near the surface of the liquid can be ignited. The lower the flash point, the greater the hazard. Preventing ignition of combustible liquids requires keeping them at temperatures lower than flash point, and if this cannot be avoided, additional safety precautions must be taken to prevent ignition. Combustible liquids require specialized safety precautions, handling practices and usage practices. They can be further divided into class II or Class III liquids, with class II liquids having a flash point of 100 degrees Fahrenheit or more and Class II liquids having a flash point of 140 degrees Fahrenheit or more.
