Hot Ideas

Q. When you are working with electricity, is it safer to be grounded?

A. It’s better if you stay insulated from ground. If you are grounded, and you come in contact with the “hot” side of the line, there will be a current path through your body between “hot” and ground.

If you are insulated from ground, there will be no current path. This does not mean that you are totally safe. It is possible to accidentally contact ground with one part of your body and “hot” with another. Then there will be a current path through your body. The best safety measure is to work with one hand in your back pocket.

The most dangerous path is one that goes through your heart. By working with one hand in your pocket, you minimize the risk of having current pass from one arm, through your chest, and through the other arm.
