When must a hard hat be worn?

A hard hat must be worn when there are overhead hazards present because it serves as a protective measure to prevent head injuries from falling objects or accidental bumps. The primary purpose of a hard hat is to safeguard workers in environments where there is a risk of impact or penetration from items falling from above. This makes it crucial for maintaining safety in various work settings, particularly in construction or maintenance activities where such hazards are common.

While other scenarios, such as working at heights or being in a construction zone, may necessitate the use of a hard hat, the most direct reason for wearing one is the presence of overhead hazards. Therefore, in any situation where there is a potential for something to fall and cause injury, a hard hat is essential. Using it proactively helps to ensure a safer work environment for technicians and workers in general.
