When should a safety harness be worn?

A safety harness should be worn when working at heights where fall protection is required because it is a critical safety measure designed to prevent injuries from falls. In construction and various other industries, regulations often mandate the use of fall protection systems when employees are exposed to fall hazards, typically when working elevated above a certain height. This is to safeguard their lives and ensure compliance with occupational safety standards.

Wearing a harness at all times on a construction site would not be practical or required, as safety gear is typically used based on specific tasks and hazards present. During breaks or while carrying heavy materials, a harness is not necessary unless there is an immediate risk of falling. Thus, the primary reason for utilizing a safety harness revolves around the height at which a worker is performing their tasks and the associated risk of falls, underscoring the importance of context in safety practices.
