- AClass 3 - Flammable
- BClass 3 - Combustible
- CClass 2 - Flammable Gas
- DClass 9 - Miscellaneous
Show answer & explanationAnswer & explanation
Correct answer: A. Class 3 - Flammable
A flammable liquid is defined as a liquid that has a flash point below 100°F (37.8°C). Since the flash point is 95°F, it falls into the Class 3 Flammable Liquid category.
Why the other options are wrong
- B. Combustible liquids have a flash point at or above 100°F and below 200°F.
- C. Flammable gas is Class 2 and refers to materials that are gases at standard temperature and pressure, not liquids.
- D. Class 9 is for miscellaneous hazardous materials that don't fit other classes, and a liquid with a flash point is specifically classified as Class 3.
Flammable Liquid Definition
A liquid that has a flash point below 100°F (37.8°C). These are classified as Class 3 hazardous materials.
- Flash point below 100°F.

Memory trick: Below 100°F, it's Flammable; 100-200°F, it's Combustible.
