Which is an example of a biological hazard?

An example of a biological hazard is pathogens and infectious materials. Biological hazards are organisms or substances produced by organisms that pose a risk to human health. This includes various forms of bacteria, viruses, fungi, and other microorganisms that can cause diseases in humans, animals, or plants. Exposure to these pathogens can occur through various routes, including inhalation, ingestion, or contact with skin, making them a significant concern in health and safety practices.

In contrast, chemical spills represent a chemical hazard, as they involve harmful substances that can cause toxicity or other adverse health effects. Open flames are a physical hazard, posing risks of burns or fire hazards. Noise pollution, while potentially harmful to hearing and health, falls under the category of environmental hazards rather than biological. Thus, the selection of pathogens and infectious materials as the example of a biological hazard is accurate and highlights a critical aspect of safety considerations in various environments, especially in healthcare and laboratory settings.
