What must be done prior to working on high-voltage lines?

Before working on high-voltage lines, it is essential to de-energize the lines and follow lockout/tagout (LOTO) procedures. This practice is critical for ensuring the safety of personnel, as high-voltage lines carry a significant risk of electric shock and other hazards. De-energizing the lines eliminates the electrical energy that could pose a danger to workers, and the lockout/tagout procedures ensure that no accidental re-energizing occurs while work is being performed. By adhering to these protocols, workers maintain a controlled environment, reducing the risk of accidents and injuries.

While wearing insulated gloves, notifying the local power company, and using a voltage tester are also important safety measures related to working with high-voltage electricity, they do not take precedence over the fundamental safety practice of ensuring the lines are de-energized. The lockout/tagout procedures are a critical step in maintaining workplace safety and ensuring that all potential energy sources are properly managed before work begins.
