In the UN labeling system, which class number corresponds to oxidizing substances?

Explanation:
In UN labeling, hazard categories are numbered, and oxidizing substances are placed in Class five because of their tendency to release oxygen or otherwise promote combustion, which can intensify fires. This group also includes organic peroxides as related oxidizing hazards. So the number that represents oxidizers is five. The other numbers correspond to different hazards (like flammable liquids or toxic substances), which is why they don’t indicate oxidizers.
