When servicing hybrid or electric emergency vehicles, what protective measures are required?

• A. Arc-rated PPE including insulated gloves, face shield, and following OEM procedures
• B. No PPE is required
• C. Only sunglasses and gloves
• D. PPE is optional if the vehicle is cool

Answer: (A)

Working around high-voltage systems in hybrid or electric emergency vehicles requires arc-rated protective gear and proper energy control. The risk isn’t just shock from a live wire; an arc flash can cause severe burns even if the vehicle seems off. The best safety approach is to wear arc-rated insulating gloves along with a face shield and to follow the OEM procedures for isolating and verifying zero energy before any service. The arc-rated gloves provide insulation against electrical current, the face shield protects the eyes and face from an arc event, and sticking to OEM procedures ensures correct de-energizing, locking out energy sources, and using the right tools and sequence. Sunglasses and regular gloves don’t offer sufficient protection against arc flash or high-voltage shock, and assuming a vehicle is safe because it’s “cool” is not reliable. Always verify proper PPE and adherence to the manufacturer’s procedures before working on these systems.
