CDL Hazardous Materials Endorsement (HME)Bulk Tanks and Other ContainersEasy
A carrier is preparing to transport a bulk quantity of a hazardous material that is a liquid with a flash point of 105°F (40.5°C). The material is in a bulk packaging designed for liquids. According to hazardous materials regulations, what classification applies to this material?
- ACombustible liquid
- BCorrosive liquid
- CMiscellaneous hazardous material
- DFlammable liquid
Show answer & explanationAnswer & explanation
Correct answer: A. Combustible liquid
A combustible liquid is defined as a liquid that has a flash point at or above 100°F (37.8°C) and below 200°F (93°C). Since the flash point is 105°F, it falls within this range.
Why the other options are wrong
- B. Corrosive liquids are defined by their ability to cause visible destruction or irreversible alteration to living tissue or steel, not by flash point.
- C. Miscellaneous hazardous materials are Class 9 materials that do not fit into other hazard classes.
- D. Flammable liquids have a flash point below 100°F.
Combustible Liquid
A liquid that has a flash point at or above 100°F (37.8°C) and below 200°F (93°C).
- Flash point between 100°F and 200°F
- Can ignite under specific conditions
- Less volatile than flammable liquids
Memory trick: Flash points dictate if it's hot enough to ignite.
