What is the main hazard encountered when working on power lines?

When working on power lines, the primary hazard is electrocution from live wires. Linemen work with high-voltage electricity, and if they come into contact with or are within close proximity to live conductors, the potential for severe electrical shock or electrocution is significantly high. This risk necessitates strict safety protocols, including the use of personal protective equipment, isolation of power sources, and adherence to safety guidelines to manage the dangers associated with electricity.

Understanding this hazard is crucial for linemen because even a momentary lapse in safety can result in life-threatening injuries or fatalities. Training programs emphasize the importance of recognizing and mitigating the risks posed by live wires, as well as ensuring that all safety procedures are followed to protect not only the individual lineman but also the team they work with. This focus on electrical hazards is paramount in training and day-to-day operations for those working with power lines.
