The National Fire Protection Agency (NFPA) produces fire and life safety standards covering a wide array of risk exposure, including electrical safety. NFPA 70E sets safety requirements for any worker exposed to 50 volts or more. Workers exposed to 50 or more volts must be trained to be “Qualified Electrical Workers” according to the Standard. Qualified workers demonstrate the ability to test systems and prevent arc flash along with other competencies, including implementing OSHA’s Lockout/Tagout Standard (1910.147). NFPA 70E also sets requirements for Personal Protective Equipment while working on electrical equipment and removing someone safely from an electric current.

Current battery systems for electric cars typically have operating voltages of 200-600 volts, and output current can reach 500A. Battery capacity directly affects the driving mileage of EVs and also impacts charging efficiency and charging time, so we can expect these numbers to climb.

Resources for compliance are built into the EV training service technicians receive from the manufacturer, aside from possibly some program development and/or recordkeeping. NHADA Loss Prevention will be able to assist in these deficient areas.

The bigger challenge rests with independent service repair operations that may have numerous EV brands to work on. NFPA 70E requires “Qualified” workers to be trained and have expertise specific to the hazard, and not all EV systems are even remotely
the same.

Loss Prevention recommends that when technicians are trained on EV service, all members ensure compliance with NFPA 70E, and OSHA’s Lockout/Tagout is part of the program. Furthermore, independent service, collision and towing operations must ensure their technicians are safe across a broad exposure to numerous high-voltage electrical system designs.

NFPA has free resources related to EV fires, including free training and emergency response guides for every alternative fuel vehicle.

There is also a paid app that has more details, is interactive, and has other vehicles besides cars, but it is not free.

NHADA Loss Prevention will continue to provide members with information and resources related to EV service and compliance with electrical safety standards. We are also partnering with companies to provide industry-specific EV Safety Training.
