What are the two main hazards linemen face when working at heights?

Linemen who work at heights face significant risks primarily due to the nature of their work environment. Falls are one of the most evident hazards. When working on poles, towers, or other elevated structures, linemen are at risk of losing their balance or having equipment failure that can lead to a fall. Proper fall protection measures, such as harnesses and secured climbing techniques, are critical to safeguarding against this risk.

Electrical exposure is the second main hazard. Linemen often work on or near live electrical lines, increasing their risk of electrocution or electric shock. Knowledge of electrical systems, the use of proper personal protective equipment, and adherence to safety protocols are essential to mitigate this danger effectively.

While other hazards such as weather conditions and equipment failure can pose risks, the specific combination of falls and electrical exposure distinctly characterizes the primary threats faced by linemen working at heights.
