Which of the following hazards can occur during elevator maintenance?

During elevator maintenance, mechanical injuries are a significant hazard due to the nature of the equipment and tasks involved. Technicians often work in close proximity to moving parts, such as pulleys, belts, and gears, which can cause entrapment or crushing injuries if proper safety precautions are not followed. Additionally, the process of securing and releasing various components introduces risks of pinching or cutting fingers.

Elevator systems also include heavy parts that can fall or shift unexpectedly, posing further risks of injury during maintenance activities. Hence, understanding the mechanical aspects and using appropriate protective gear is essential to minimize the risk of injuries in the maintenance environment.

While electrical fires, traffic accidents, and exposure to extreme temperatures can present risks in different contexts, they are not as directly linked to the specific activities that take place during elevator maintenance as mechanical injuries are.
