Can contact with live electrical circuits cause burns to the skin surface and underlying tissue?

• A. Yes
• B. No
• C. Maybe
• D. Only with water present

Answer: (A)

Touching a live electrical circuit can produce burns because the electrical energy flowing through the body is converted to heat in the tissues. The amount of heat generated depends on how much current passes through, how long it flows, and the resistance of the path through the body. That heat can damage both the skin surface and deeper tissues, so internal injuries can occur even if the outside appearance seems only mild. Water or moisture increases the skin’s conductivity and can make injuries worse, but burns can happen without water as well, so moisture is a factor that amplifies risk rather than a prerequisite.
