What are Class I II and III liquids?

Class I liquids are the most hazardous from a fire safety standpoint, while Class IIIB liquids are the least hazardous. Class IA liquids are liquids that have flash points below 73 °F (22.8 °C) and boiling points below 100 °F (37.8 °C). Additionally, unstable flammable liquids are treated as Class IA liquids.

What does a flammability rating of 1 mean?

Level 1 – Materials that are normally stable, but become explosive at elevated temperatures and pressure. ◆ Level 0 – Materials that are stable even under exposure to fire. A chemical hazard rating at the highest level should be given to a room if chemicals are present in quantities of five (5) gallons or more.

What is the class of diesel fuel?

Class II liquids
Typical Class II liquids include liquids such as camphor oil, diesel fuel, pine tar, methanol, and other solvents. Class II liquids are combustible liquids that have a flash temperature point at or above 100 °F (37.8 °C) and below 140 °F (60 °C).
