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.

Is motor oil a Class 3 flammable liquid?

Engine oils normally have a flash point greater than 150 °C. This means that they're not a Class 3 Flammable Liquid, as flammable liquids must have a flash point below 60 °C. Therefore, engine oils are classed as combustible liquids.

What is a Class 1 chemical?

What are Class 1 dangerous goods and why are they classed as dangerous? Class 1 goods are products that possess the ability to alight or detonate as a consequence of a chemical reaction. Explosives are classified as a hazardous product for a pretty clear reason – they can explode.
