What is the primary purpose of installing proper barricades near overhead power lines?

The primary purpose of installing proper barricades near overhead power lines is to warn personnel of potential hazards. Overhead power lines can pose significant dangers, including the risk of electrocution or severe injury due to accidental contact with conducting elements. By installing barricades, workers are alerted to approach with caution and are made aware of the risks associated with working in proximity to these power lines. This precaution is essential to ensure the safety of personnel on the job site, as it creates a clear visual indication of danger and helps maintain a safe working environment.

While barricades may also serve to increase visibility or indicate safe operating conditions, these aspects are secondary to the primary function of hazard warning. The focus is on ensuring everyone in the vicinity understands the potential danger and takes appropriate measures to avoid it.
