What are some potential hazards of working on live electrical circuits?

The potential hazards of working on live electrical circuits specifically include electric shock, burns, and fires. When an electrician interacts with an energized circuit, there is a risk of electric shock, which can have serious, often fatal consequences depending on the voltage and current involved. Electric shock can lead to muscle contractions, respiratory failure, or even cardiac arrest.

Burns can occur not only from the current itself but also from arcing that generates high temperature, causing thermal injuries to the skin and deeper tissues. Furthermore, live electrical work carries a significant fire risk. Faulty connections or accidental shorts can ignite combustible materials nearby, leading to potential property damage and endangering lives.

While other options mention various hazards in the workplace, they do not specifically address the dangers inherent to live electrical circuits, making this answer the most relevant and accurate in the context of electrical safety.
