Final answer:
To avoid grounding hazards, wearing insulated shoes and working 'one-handed' are recommended practices. Insulated shoes prevent a conductive path to ground through the feet, while the 'one-handed' technique reduces the risk of electric current passing through the heart.
Step-by-step explanation:
Grounding is the process by which a conductor can be fixed at zero volts by connecting it to the earth with a good conductor. When working with electrical circuits, particularly high-power ones, a key safety precaution is to wear insulated shoes. These shoes provide a high resistance path and prevent the formation of a conductive path through your body to the ground. Additionally, when engaging with electrical circuits, it is recommended to work using the "one-hand" technique, preferably by keeping the other hand in your pocket. This reduces the risk of creating a conductive path across the heart, which can be extremely dangerous.
Our bodies are good conductors due to water content, so it's critical to ensure that when working with electricity, one does not become a pathway for the current to flow to the ground, especially across the heart. The one-hand technique is sensible because it minimizes the potential of current passing from one hand to the other through the heart, which can be lethal.
