What is NOT considered a health hazard?

Working at heights is primarily regarded as a safety hazard rather than a health hazard. Safety hazards pose immediate risks of physical injury, such as falls, while health hazards typically relate to exposure to substances or conditions that can cause long-term health issues.

In this context, noise, dust, and heat are all factors that can lead to chronic health conditions or impairments if proper precautions are not taken. For example, excessive noise can lead to hearing loss, dust exposure can cause respiratory problems, and extreme heat can result in heat stress or related health issues over time.

Since working at heights does not intrinsically involve a prolonged exposure to a harmful substance or condition that affects health, it is categorized differently, reinforcing why it fits as the option that does not align with the concept of a health hazard.
