Which hazard class number is assigned to oxidizers?

Explanation:
Oxidizers carry the hazard class number five because their defining property is that they release or provide oxygen, which can fuel and accelerate combustion of other materials. They aren’t necessarily flammable themselves, but they make fires more intense by supplying an oxidizer to the fuel. In the hazard classification system, five specifically covers oxidizers (with 5.1 for oxidizers and 5.2 for organic peroxides). Other numbers correspond to different hazard families: one is explosives, three is flammable liquids, and seven is radioactive materials.
