Why should responders cut the power source before treating a patient with electrical burns?

• A. To prevent bleeding
• B. To protect yourself by cutting the power source
• C. To reduce swelling
• D. To increase oxygen delivery

Answer: (B)

The primary safety rule with electrical injuries is to remove the live electrical source before touching or treating the patient. Cutting the power stops the current from flowing through the person, which prevents further internal damage and, just as importantly, protects you from getting shocked while you assess and manage injuries. Once the circuit is de-energized, you can safely proceed with life-supporting measures and wound care. If you can’t reach the power source directly, use a non-conductive object to move the patient away from the source and then shut off power when it’s safe to do so. While swelling or oxygen delivery are considerations, the immediate priority is eliminating the electrical hazard.
