Give an example of a biological hazard.

Bacteria, viruses, and fungi are classified as biological hazards because they are living organisms that can cause harm to human health. Biological hazards primarily include pathogens that can lead to diseases, infections, and other health-related issues. These hazards are significant in various environments, especially in healthcare settings, laboratories, and food handling industries, where exposure to these microorganisms can occur.

In contrast, the other options represent different categories of hazards. Heavy machinery is a physical hazard due to the risk of injury it may pose during operation. Toxic chemicals fall under chemical hazards, which pertain to substances that can cause adverse health effects. Electrical currents are considered electrical hazards, associated with risks of shock or electrocution. Understanding the distinction between these categories helps in identifying and managing risks effectively within different environments.
