Hazard Class 1 includes:

• A. Explosives
• B. Flammable Liquids
• C. Poisons
• D. Corrosives

Answer: (A)

Hazard Class 1 is for materials that can detonate or release energy rapidly, producing an explosion. This includes explosives used in mining, construction, and demolition—things like dynamite, blasting caps, and other energetic compounds. Because of the risk of a sudden blast, these materials are tightly regulated in how they’re manufactured, packaged, labeled, and shipped. Other hazardous material types are categorized differently: flammable liquids are those that ignite easily in air and burn, but they don’t detonate; poisons (toxic materials) cause illness or death if absorbed or inhaled; and corrosives cause severe damage to skin and other materials on contact. So, explosives are the materials that belong to this category, making them the correct choice.
