Hazard Class 5.1 includes which category?

• A. Organic Peroxide Class
• B. Poison/Infectious Substance Class
• C. Explosives and Blasting Agents Class
• D. Oxiders Class

Answer: (D)

Hazard class 5.1 covers oxidizers—substances that release oxygen or another oxidizing agent and thereby fuel or accelerate combustion. They may not burn on their own, but they dramatically enhance fires when they contact fuels, making them a major fire hazard. Organic peroxides are a separate subclass (5.2), explosives and blasting agents belong to Class 1, and poisonous or infectious substances fall under Class 6 (toxic) or 6.2 (infectious). So the category that fits 5.1 is oxidizers.
