Question: 1 / 400

What classification does a flammable solid fall under in DOT's hazardous classifications?

Class 1

Class 3

Class 4

A flammable solid falls under Class 4 in the Department of Transportation's hazardous classifications. This classification specifically encompasses flammable solids, which include materials that are solid at room temperature and can easily ignite through friction, heat, or moisture.

Class 4 is further divided into three subdivisions:

- 4.1 includes flammable solids that are readily ignitable under specific conditions.

- 4.2 covers flammable solids that can spontaneously combust.

- 4.3 consists of substances that may emit flammable gases when in contact with water.

Understanding this classification is crucial for safe handling, transport, and regulation compliance, as it outlines the potential risks associated with these materials. Proper recognition of flammable solids as a distinct category ensures that safety measures are appropriately implemented to mitigate hazards during transportation and storage.
