Which of the following is NOT a category of hazard?

The correct response indicates that "Mechanical" is not a category of hazard in the context provided. However, in occupational health and safety, hazards are often classified into several primary categories to facilitate understanding and management. These categories typically include:

• Chemical hazards, which involve exposure to harmful substances that can cause health issues or injuries.

• Biological hazards, which relate to exposure to living organisms or their by-products that may pose health risks, such as bacteria, viruses, or fungi.

• Physical hazards, which can arise from exposure to environmental factors that can cause harm, including noise, radiation, and ergonomic issues.

Mechanical hazards, while they could be implied under some categories, are not typically designated specifically as a standalone category in standard safety classifications. Rather, mechanical risks are often encompassed within the broader categories or may be discussed in the context of physical hazards, as they frequently involve the operation of machinery or equipment that can lead to injuries. Hence, identifying "Mechanical" as the option that does not fit into the established categories reflects an understanding of these classifications within the safety framework.
