Which of the following is a category of chemical hazards?

• A. Biological Hazards
• B. Nuclear Materials
• C. Toxic Industrial Chemicals
• D. Radiological Substances

Answer: (C)

Chemical hazards are dangers that come from substances themselves due to properties like toxicity, reactivity, flammability, or corrosivity. Toxic industrial chemicals are a recognized category of chemical hazards because they are hazardous chemicals used in industry that can cause serious health effects or environmental harm if released, mishandled, or people are exposed. They can poison, irritate, or injure, and managing them requires protective measures and emergency planning.

Biological hazards involve living organisms or their products, not chemicals. Nuclear materials and radiological substances relate to radiation hazards, not chemical hazards, so they aren’t classified under chemical hazards.
