Final answer:
When dealing with energized circuits, wearing non-conductive, insulated gloves is necessary to prevent electrical shocks. Insulated gear protects against the conduction of electricity through the body, with gloves providing a key barrier when directly handling live circuits.
Step-by-step explanation:
When working with energized circuits or equipment, it is essential to wear non-conductive, insulated gloves or other effective Personal Protective Equipment (PPE) to protect against electrical shocks. Our bodies are relatively good conductors of electricity largely due to the water content, leading to dangerous conditions if in contact with a voltage source and ground. To safeguard against this, insulated shoes provide high resistance, thus preventing a pathway to ground for electrons. Similarly, wearing insulated gloves creates a barrier against electrical currents that could otherwise pass through the body when handling live circuits. The insulation on live/hot wires specifically prevents shock hazards by stopping current from reaching the skin, but it does not prevent thermal hazards which are related to heat. Additionally, working with one hand or keeping one hand in your pocket while handling electrical systems can reduce the risk of current passing across the heart, which can be fatal.
