What is the main hazard when working with energized electrical equipment?

The primary hazard when working with energized electrical equipment is electrical shock or electrocution. This risk arises because humans can conduct electricity, and when direct contact is made with live electrical components, it can lead to the flow of electrical current through the body. This can cause serious injuries or even death, depending on the voltage and the duration of exposure to the electrical current.

Understanding this hazard is critical for ensuring safety in the workplace. Proper safety practices, such as using insulated tools, wearing appropriate personal protective equipment (PPE), and implementing lockout/tagout procedures, are essential for minimizing this risk while working on or near energized equipment.

While other hazards such as fire, circuit overload, and device malfunction are also important to consider in electrical work, the immediate threat to personal safety from electrical shock or electrocution makes it the most significant concern when engaging with energized electrical systems.
