Final answer:
Use a one-handed approach when working with high-power electric circuits to reduce the risk of electric shock. When handing over power tools, ensure they are safely turned off to prevent accidents.
Step-by-step explanation:
The practice of working with high-power electric circuits using a "one-handed" approach or keeping "one hand in your pocket" is advised to minimize the risk of electric shocks. Conducting electricity through the heart can be lethal, and since the path of electric current can cross the heart when both hands are involved, this approach significantly reduces the chances of fatal accidents. When handing power tools, like socket wrenches or a power drill, to another person, ensure the tool is off and in a safe condition to prevent any unintentional activation which could harm the operator or damage the equipment.
When working with high-power electric circuits, it is advised to work with one hand or keep one hand in your pocket. This is a sensible suggestion because it helps prevent electrical shock. Electricity always seeks the shortest path to the ground, and if you accidentally come into contact with a live wire while using a power tool, the electricity will flow through your body, causing a potentially dangerous shock.
