What types of hazards are classified as Physical Hazards?

Physical hazards encompass a range of environmental factors that can cause harm to individuals or property, and the correctly identified examples—noise, radiation, temperature extremes, and ergonomics—illustrate this classification well. Noise can lead to hearing loss and other health issues, making it a notable physical hazard. Radiation exposure can cause both immediate harm and long-term health effects, including cancer. Temperature extremes, whether hot or cold, can lead to a variety of health problems, such as heatstroke or frostbite, making them clear examples of physical hazards. Lastly, ergonomics involves the design and arrangement of workplaces to prevent musculoskeletal injuries, highlighting how physical conditions can impact health and safety.

The other options do not capture the full scope of physical hazards. While noise and temperature extremes are indeed physical hazards, claiming that they are the only examples omits significant threats like radiation and ergonomic factors. Chemical spills and leaks, on the other hand, are classified as chemical hazards rather than physical, while focusing solely on chemical and biological hazards ignores the physical aspects that can also endanger individuals. Thus, the range provided in the correct answer accurately reflects the various kinds of physical hazards present in different environments.
