Which risk is NOT associated with working on live circuits?

Heat exhaustion is not typically associated with working on live circuits. While electric shock, equipment damage, and burns are direct hazards encountered when dealing with live electrical components, heat exhaustion relates more to prolonged exposure to high temperatures or strenuous activity rather than electrical hazards.

When working on live circuits, individuals are exposed to the risk of electric shock if they come into contact with energized components, which can lead to serious injury or fatality. Additionally, equipment damage can occur as a result of incorrect handling or faults in the circuitry, potentially leading to malfunctions or fires. Burns may also happen from electrical arcs or contact with hot surfaces or components.

In contrast, heat exhaustion arises from environmental conditions or physical exertion and is not specifically related to the electrical work itself, making it the correct response in this scenario.
