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

Uneven flooring is a clear example of a physical hazard because it directly poses a risk of injury or accident in the environment where individuals walk or work. Physical hazards refer to physical factors in the environment that can cause harm or injury, such as slips, trips, and falls. Uneven flooring can lead to tripping and falling, which can result in various injuries such as sprains, fractures, or other serious accidents.

In contrast, unclear communication and inadequate training are more related to organizational or human factors rather than physical characteristics of the environment. Poor ventilation also falls under environmental concerns but is primarily associated with health risks rather than immediate physical hazards like uneven flooring. Thus, identifying uneven flooring as a physical hazard highlights its direct impact on safety in a workplace setting.
