Mitigating Overhead Electrical Hazards: Safeguarding Job Sites

Overhead electrical hazards pose a significant threat to workers across various industries, as underscored by statistics from the Department of Labor accidents. These accidents often result in severe injuries or even fatalities, emphasizing the crucial need for stringent safety measures at job sites. According to the latest available data, a substantial number of workplace accidents stem from contact with overhead power lines or electrical equipment. These incidents can occur during construction, maintenance, or other activities involving elevated structures and machinery. The consequences of such accidents can be dire, causing not only harm to workers but also significant disruptions to project timelines and company operations.


The image below depicts the aftermath of a two-man crew who arrived at a job site to unload wood chips from the aerial lift truck. Upon completion, the dump bed was lowered but the driver and spotter did not lower the boom. As the driver pulled forward to connect the chipper, the boom contacted the overhead lines. The driver and spotter exited the vehicle and moved away due to one of the communication lines resting across the aerial lift.

To minimize the risks associated with encountering overhead electrical hazards, workers must understand how to perform mental risk assessments and vehicle walk-arounds, which is imperative before commencing any work near overhead power lines and other utilities. This includes identifying potential danger zones, assessing the voltage of the lines, and reviewing safe distances.


Regular training sessions that cover electrical hazard recognition, emergency response protocols, and the proper use of personal protective equipment (PPE) are essential for all workers on the site. Establishing clear communication channels and safe distances from power lines, using barriers and warning signs, also plays a pivotal role in accident prevention. Finally, maintaining a vigilant approach and adhering to these precautions consistently are vital to fostering a culture of safety and ensuring the well-being of all personnel involved in the project.
