Which item is classified as a Biological Hazard?

• A. Biological hazard
• B. Physical hazard
• C. Chemical hazard
• D. Ergonomic hazard

Answer: (A)

Biological hazards come from living organisms or their components that can cause infection, illness, or allergic reactions. In healthcare and surgical settings, this includes bacteria, viruses, fungi, parasites, prions, and materials contaminated with blood or body fluids. The option that fits this category is the one describing a biological hazard itself, because it names the hazard type by origin. Physical hazards cover things like radiation, noise, and extreme temperatures; chemical hazards involve hazardous substances such as solvents and sterilants; ergonomic hazards relate to strain from posture, repetition, or lifting. Knowing the distinction helps you quickly classify risks in the environment and apply appropriate controls like standard precautions, proper PPE, and safe handling of contaminated materials.
