What should you do for touch potential?

• A. Remain inside the vehicle and call for help.
• B. Jump with two feet from the car.
• C. Touch the metal frame to discharge.
• D. Run away in a straight line.

Answer: (B)

Touch potential comes from voltage differences in the ground around energized sources. If you must exit a vehicle that could be energized, you want to minimize the path electric current can take through your body. Jumping clear with both feet together ensures you land at the same electrical potential, so there’s no moment when one foot is at a higher voltage than the other. This reduces the chance of a shock as you move away. After you land, move away in small steps with your feet together to avoid creating new potential differences. Do not touch the car frame to discharge, and don’t run straight away, since those actions can establish unsafe current paths.
