What are liquids with flashpoints of less than 100 degrees Fahrenheit classified as?

Liquids with flashpoints of less than 100 degrees Fahrenheit are classified as flammable liquids. A flashpoint is the lowest temperature at which a liquid can vaporize to form an ignitable mixture in air. The distinction is important in safety regulations and handling practices.

Flammable liquids have a flashpoint below 100 degrees Fahrenheit, indicating that they can easily ignite and pose a significant fire hazard under standard temperature conditions. This classification helps in implementing appropriate safety measures when storing, transporting, or using these liquids.

In contrast, combustible liquids have higher flashpoints and thus present a different level of risk. Understanding these classifications is crucial for ensuring safety in environments where these substances are present.
