NOT listed as a Class 5 oxidizer?

• A. Oxidizer
• B. Organic peroxide
• C. Water
• D. Oxygen

Answer: (C)

Class 5 hazards are oxidizers and organic peroxides—substances that can contribute to or promote combustion by releasing or supplying oxygen. Water does not fit this category because it does not provide oxygen and, in fact, helps to suppress fires by absorbing heat and cooling the surroundings. Oxygen is itself a direct oxidizer, supporting burning, and organic peroxides are reactive compounds that release oxygen-containing species when they decompose, making them highly oxidizing hazards. Since water neither supplies oxygen nor promotes oxidation, it is not listed as a Class 5 oxidizer.
