What is an important precaution when working with high-voltage equipment?

When working with high-voltage equipment, verifying that lockout/tagout procedures are implemented and followed is critically important. Lockout/tagout (LOTO) procedures are designed to ensure that machinery or equipment is properly shut off and not able to be started up again prior to the completion of maintenance or servicing. This is essential for preventing accidental energization of equipment, which could lead to severe electrical shocks, injuries, or even fatalities.

By adhering to these procedures, electricians can effectively safeguard themselves and their coworkers from potential hazards associated with high-voltage systems. This critical safety measure ensures that the energy sources are isolated and controlled, offering a protected environment for maintenance and inspection tasks. Therefore, following lockout/tagout protocols significantly enhances safety when dealing with electrically powered machinery.

In contrast, ensuring equipment is powered on before inspection, performing maintenance without personal protective equipment (PPE), and using metal tools are practices that would significantly increase the risk of electrical hazards and accidents. These actions do not align with safety best practices in high-voltage environments.
