What safety procedure must be followed when working on overhead lines?

When working on overhead lines, using appropriate personal protective equipment (PPE) and maintaining safe distances is crucial for ensuring both the worker's safety and the integrity of the work being performed. PPE, such as insulated gloves, hard hats, and eye protection, is specifically designed to protect against electrical hazards, falling objects, and potential accidents that could occur while working at heights.

Maintaining safe distances from live electrical components is essential to avoid accidental electrocution or injury. Overhead lines carry high-voltage electricity, and keeping a safe distance significantly reduces the risk of electric shocks. This safety procedure aligns with standard industry practices and regulations aimed at protecting workers in potentially hazardous electrical environments.

The other options lack critical elements of safety. Using only hand tools without PPE disregards the protective measures necessary for working in such environments. Performing work quickly without safety checks increases the risk of accidents and injuries by neglecting proper protocols. Limiting ladder use to over 10 feet does not encompass a comprehensive approach to safety regarding all types of work situations and heights involved in overhead line maintenance.
