Answer Notes

When a person is unconscious and in contact with high voltage, their body is actively conducting electricity. Touching them directly—even by grabbing an arm or a leg—will allow that same lethal current to flow into your body, potentially electrocuting you as well. The absolute safest method is to completely de-energize the power source before attempting any physical rescue. This means flipping the main breaker, pulling the plug, or throwing the disconnect switch. Using improvised tools like a blanket is extremely risky, as high voltage can easily arc or travel through hidden moisture (like sweat) in the fabric.
