Which of the following is an example of a physical hazard?

Noise pollution is categorized as a physical hazard because it involves environmental factors that can cause injury or health issues to individuals in a workplace. Physical hazards include various elements that can cause harm through direct physical means, such as noise, vibration, temperature extremes, and more. In this case, excessive noise can lead to hearing loss, increased stress, and reduced concentration, impacting overall well-being and productivity.

The other options pertain to different types of hazards: unstable work practices relate to organizational or procedural hazards, exposure to chemical fumes signifies chemical hazards, and poor ergonomic design falls under ergonomic or biomechanical hazards. While all these aspects are essential to consider for health and safety, it is the noise pollution that distinctly represents a physical hazard in this context.
