As long as you follow the EV guidelines, you are going to have to use the proper PPE and insulated tools.

Staying safe while working on an electric vehicle requires the correct shop equipment as well as the correct personal protective equipment (PPE) and shortcuts are simply not an option. Let’s take a look at everything you are going to need.

We’ll start with PPE and electrical safety gloves. Class zero electrical insulating gloves rated for 1000 volts are required for EV service. Simply put, these gloves prevent high voltage from traveling through your hands, and they must be tested every time you use them by checking for a pinhole or any damage that could allow voltage to pass through a glove. A glove inflator is the most efficient way to do this. Insulating gloves must also be clean and dry so there are no conductive substances that can allow high voltage to travel outside the glove to your arm. Treat these safety gloves with extreme care. They can be damaged easily and they’re sensitive to UV rays, so they should be stored in a dark, dry environment. A ventilated UV-resistant bag is the best option. Safety gloves must also be re-certified every six months. You’ll also wear them with a leather outer glove to protect them, most prefer to wear an inner cotton glove as a liner to allow your hands to breathe.
