Safe Work Practices

To work on or near live parts, you must do the following:

Worker using protective equipment is performing a switching operation to isolate the secondary power from a facility.
  • Have a written live-work permit for the work to be done.
  • Wear the right PPE to protect against electric shock and arc flash. Never wear clothing made from synthetic materials, such as acetate, nylon, polyester, polypropylene, or rayon - alone or combined with cotton. Such clothing can burn and melt into your skin.

    The PPE that is needed depends on the type of electric work being done. The minimum PPE required while working on line circuits would be an untreated natural fiber long-sleeve shirt and long pants plus safety glasses with side shields. Depending on the voltage and the electric task to be done, different types of PPE are required.

    Fire-resistant protective clothing can include multi-layer flash suit jacket and pants, wraparound face shield, double-layer switching hood, voltage-rated gloves with leather protectors, electrically rated hard hats, and so forth.

  • Use the proper type of protective equipment, such as insulated tools and/or handling equipment that is rated for the voltage. These can include insulated fuse or fuse holding equipment, nonconductive ropes and handlines, fiberglass-reinforced plastic rods, nonconductive portable ladders (such as, fiberglass), protective shields, rubber insulating equipment, voltage-rated plastic guards, and so forth.
