Why should working on energized circuits be avoided?

Working on energized circuits should be avoided primarily because it significantly increases the risk of electrical shock and injury. When a worker interacts with live electrical components, they are exposed to dangerous voltages that can lead to severe injuries or even fatalities. This risk is not limited to direct contact with wires or terminals; the presence of energized components can also create hazards such as arc flash or arc blast incidents, which can occur without direct physical contact.

This heightens the urgency for safety protocols and protective measures when dealing with electrical work. Prioritizing safety by ensuring that circuits are de-energized before work begins minimizes the potential for accidents and injuries, thereby creating a safer work environment.

While other factors, such as time and efficiency, might come into play in decision-making for repair or maintenance tasks, they do not outweigh the critical aspect of safety. Ensuring that workers are not exposed to energized systems is a fundamental principle of electrical safety practices.
