What are the safety precautions when working with live circuits?

When working with live circuits, using insulated tools and wearing appropriate personal protective equipment (PPE) are critical safety precautions. Insulated tools prevent electric shock by ensuring that the user does not come into direct contact with conductive parts. This is essential when dealing with live circuits, as electricity can travel through the body if contact occurs, leading to severe injury or fatality.

Proper PPE, such as rubber gloves, safety glasses, and flame-resistant clothing, further enhances safety by providing additional barriers against electrical hazards and unforeseen accidents. This equipment is designed to withstand electrical voltages and protect the worker from potential burns or shocks.

The other options do not align with safe practices for working on live circuits. Using uninsulated tools or improper gloves can expose you directly to electrical currents. Ensuring that all systems are connected may increase the risk without proper safety measures in place, and restricting work to daylight hours does not necessarily mitigate the electrical hazards present. Proper electrical safety protocols should always be prioritized, regardless of light conditions.
