What is one of the primary hazards associated with electrical work?

Electric shock is considered one of the primary hazards associated with electrical work because it poses a direct threat to life and health. When a person comes into contact with live electrical currents, the flow of electricity can disrupt the normal functioning of the heart and nervous system, potentially leading to serious injury or death. The severity of an electric shock can vary depending on several factors including the voltage, the pathway through the body, the duration of the exposure, and the body's condition at the time of contact.

Key safety measures, such as using insulated tools, wearing appropriate personal protective equipment, and following safety protocols, are crucial in mitigating the risk of electric shock. Understanding this hazard is essential for anyone working with or around electrical systems, as it emphasizes the importance of safety practices aimed at preventing accidents and ensuring safe working environments.
