What should be done when working on live circuits?

When working on live circuits, using extreme caution and wearing appropriate personal protective equipment (PPE) is essential for safety. Live circuits can carry dangerous levels of electrical current, which poses a serious risk of electric shock or electrocution if not handled properly. Appropriate PPE can include insulated gloves, safety glasses, and flame-resistant clothing, which protect against electrical hazards as well as potential arc flash incidents.

This practice not only safeguards the individual performing the electrical work but also minimizes risks to others in the vicinity. Employing safe work habits when dealing with live circuits is critical, as it helps ensure that the work is done safely and effectively, reducing the likelihood of accidents or injuries.

While other options like having a fire extinguisher nearby could be a good safety measure in many situations, it is not directly related to the immediate precautions necessary for working on live circuits. Access techniques or ensuring circuits are labeled, while important in broader electrical work, do not address the immediate risks associated with live electrical systems like the correct use of PPE does.
