What additional risk do hybrid/electric vehicles introduce during extrication?

• A. Low fuel pressure warning.
• B. Seat belt pretensioners.
• C. High-voltage battery systems requiring disconnect and isolation by trained personnel.
• D. Glass fragmentation risk.

Answer: (C)

Hybrid and electric vehicles bring a high-voltage electrical system into play. The battery pack and related high-voltage circuitry can remain energized after a crash, creating a real risk of electric shock, arcing, or thermal events for anyone working on the vehicle. Because of that, the extra danger is the need to disconnect and isolate the high-voltage system, a task that requires trained personnel who know the vehicle-specific procedures and safety steps. Other issues like seat belt pretensioners or glass fragmentation exist in many crashes, but they don’t introduce the unique, potentially life-threatening energy source that the high-voltage system does. Until the high-voltage system is de-energized, the vehicle should be treated as a live electrical source, and responders should follow established protocols to ensure the area is safe.
