Biological Hazards describe what?

• A. Non-living agents that may be present in the environment.
• B. Physical hazards such as noise and heat.
• C. Living organisms that can cause adverse response in humans.
• D. Chemical hazards from acids.

Answer: (C)

Biological hazards involve living organisms or their products that can cause disease or adverse health effects in people. This includes bacteria, viruses, fungi, parasites, and their toxins. These hazards can arise in environments where microbes are present and can be transmitted or proliferate—such as contaminated water, air, surfaces, or food—and may lead to infections, allergic reactions, or toxic responses. In contrast, physical hazards (like noise or heat) and chemical hazards (such as acids) are not biological, since they are non-living or non-biological in origin. So, the description that best fits is living organisms that can cause adverse responses in humans.
