Oxidizers are assigned to which DOT Class?

Explanation:
Oxidizers are assigned to DOT Class 5. This class covers materials that can yield oxygen or otherwise promote combustion, which is why they’re regulated separately from flammable liquids or explosives. Within Class 5, 5.1 designates oxidizers and 5.2 covers organic peroxides. The other classes listed map to different hazards: Class 1 explosives, Class 3 flammable liquids, and Class 7 radioactive materials. So oxidizers belong to Class 5.
