The DOT Hazard Class 1 consists of:

Explanation:
Explosives form the DOT Hazard Class 1 because this class is specifically for materials that release energy rapidly, typically through detonation or a violent explosive reaction. These substances can produce a blast, shock wave, heat, and fragmenting effects, so they require strict handling, packaging, and segregation during transport. Examples include TNT, dynamite, blasting caps, and fireworks. The other options describe different hazards: gases belong to Class 2, corrosives to Class 8, and radioactive materials to Class 7, none of which are defined by an explosive energy release.
