What hazard is unique to electric-hybrid vehicles during extrication?

• A. Gasoline fumes.
• B. No special hazards.
• C. High-voltage battery hazards requiring isolation and PPE.
• D. Mechanical hazards.

Answer: (C)

Electric-hybrid vehicles introduce a hazard not present in conventional cars: a high-voltage battery system that can stay energized even after a crash. This creates real risks of electric shock, arc flash, or battery-related fires for rescuers. Because of this, the priority during extrication is to isolate and de-energize the high-voltage system and to work with appropriate PPE and procedures. That means following the manufacturer’s instructions to disconnect or disable the high-voltage system, using insulated tools and PPE rated for electrical hazards (such as voltage-rated gloves and face protection), and ensuring the system is de-energized before handling any high-voltage components. Gasoline fumes and typical mechanical hazards are concerns in any vehicle crash, but they aren’t unique to hybrids. The key is the high-voltage battery hazard that requires deliberate isolation and protection to keep rescuers safe.
