What is a key difference between oxidizers and reactive hazards?

• A. Oxidizers can intensify fires by providing oxygen; reactive hazards may violently react with water or other materials, releasing energy or toxic products.
• B. Oxidizers are always inert and nonreactive.
• C. Reactive hazards only occur as gases.
• D. Oxidizers and reactive hazards are the same.

Answer: (A)

Oxidizers and reactive hazards create danger in different ways. An oxidizer fuels a fire by providing oxygen or otherwise supporting combustion, which can make fires burn hotter and spread more rapidly. A reactive hazard, on the other hand, involves a chemical that can react violently with other substances—such as water or incompatible materials—releasing energy, heat, gases, or toxic products. So the best description is that oxidizers intensify fires by supplying oxygen, while reactive hazards may violently react with water or other materials, producing energy or toxic products. It’s important to remember oxidizers aren’t always inert or nonreactive, reactive hazards aren’t limited to gases, and the two are distinct types of hazards.
