Which DOT Hazard Class includes Flammable solids?

Explanation:
Flammable solids are categorized under Hazard Class 4. This class is reserved for solids that can ignite or sustain combustion under certain conditions. It’s divided into three parts: 4.1 flammable solids, 4.2 solids that release flammable gases when in contact with water, and 4.3 substances that may ignite spontaneously or when heated. The other classes cover different hazards: Class 3 is for flammable liquids, Class 5 for oxidizers and organic peroxides, and Class 6 for toxic or infectious substances, so they don’t describe flammable solids.
