Excessive noise levels in the workplace are classified as a physical hazard. This is because physical hazards encompass various factors that can cause harm without direct contact, including noise, vibration, temperature extremes, and radiation.

Exposure to high noise levels can lead to hearing loss, stress, and other health issues, clearly demonstrating the potential for physical impairment and injury. This classification reflects the characteristics of noise as a stressor in the environment that affects individuals physically, particularly in terms of auditory function.

In contrast, biological hazards refer to exposure to infectious agents, while chemical hazards involve harmful substances that can cause injury or illness through inhalation, contact, or ingestion. Ergonomic hazards are related to the design of work tasks and the physical strain they may cause, such as repetitive motion injuries or strain from improper lifting techniques. These categories do not encompass the effects of noise, reinforcing the idea that excessive noise levels fit squarely within the realm of physical hazards.
