What is the recommended safety stance when approaching electric or hybrid vehicles during rescue operations?

• A. Treat as powered off
• B. Always assume powered up
• C. Verify power with meter
• D. Disconnect battery before approaching

Answer: (B)

Always assume the high-voltage system is energized until it has been isolated and de-energized by trained personnel. Electric and hybrid vehicles can retain dangerous stored energy even after the ignition is off, and multiple circuits can stay live. In a rescue, this means approach with caution, establish a safe perimeter, and avoid contact with high-voltage components until a qualified team validates de-energization using proper procedures and tools. Verifying power with a meter is important, but it doesn’t replace the need for established de-energization steps performed by those trained for it. Disconnecting the battery in the field requires specific procedures and equipment; doing so without proper training can cause arcing, re-energization, or other hazards.
