Which classification indicates a liquid is considered combustible?

The classification that indicates a liquid is considered combustible is based on its flashpoint, which is the lowest temperature at which it can vaporize to form an ignitable mixture in air. A liquid with a flashpoint more than 141°F is classified as a combustible liquid.

This designation is important for safety regulations, handling, and storage practices. Liquids that fall under this classification typically require specific measures to prevent ignition, given their potential to ignite under the right conditions. Understanding this classification helps emergency responders and hazardous materials technicians identify the risk associated with different liquids during incidents involving spills or leaks.

On the other hand, lower flashpoints indicate a higher risk of ignition, categorizing these substances differently in terms of safety protocols and handling requirements.
