    • Safety glasses with appropriate side shields when within 15 meters (50 feet) of the vehicle, either indoors or outdoors.
    • Certified and up-to-date Class "0" Insulation gloves rated at 1000V with leather protectors.
      • Visually and functionally inspect the gloves before use.
      • Wear the Insulation gloves with leather protectors at all times when working with the high voltage battery assembly, whether the system is energized or not.

    Failure to follow the procedures may result in serious injury or death.
