How is the term "biohazard" defined in relation to medical equipment?

The term "biohazard" specifically refers to biological substances that can pose a threat to human health. This includes a range of materials such as viruses, bacteria, and other microorganisms that could cause disease or infection. In the context of medical equipment, biohazards might include contaminated instruments or devices that have come into contact with infected patients or biological samples. Proper handling, disposal, and decontamination of these substances are crucial to ensure safety in healthcare settings.

While other options touch on aspects related to safety—like equipment failures, toxic chemicals, or waste products—these do not align with the precise definition of biohazard. The key focus of the term is on biological agents and their potential risks to human health, making it essential for biomedical equipment technicians to understand and mitigate these risks in their work.
