Intro to Millwright Practice Exam

Biological hazards primarily consist of microorganisms that can pose risks to human health and safety. These include bacteria, viruses, fungi, and other pathogens that might be found in various environments such as workplaces or natural settings. The presence of these microorganisms can lead to infections, diseases, or other health complications in humans, particularly if proper safety and hygiene measures are not maintained.

In contrast, inorganic materials refer to substances that do not contain carbon bonds, like metals or minerals, which are not categorized as biological hazards. Toxic chemicals involve a range of hazardous materials that have harmful effects on living organisms, but they are classified under chemical hazards rather than biological. Physical agents pertain to hazards generated through physical forces, such as noise, vibration, or radiation, which again do not fall under the category of biological hazards. Therefore, the focus on microorganisms accurately identifies the true nature of biological hazards.
