What is one of the main hazards when working with electrical circuits?

Electric shock is one of the primary hazards when working with electrical circuits because it occurs when a person comes into contact with an electric current. This can result from various factors, such as faulty equipment, improper grounding, or working with live wires. The severity of an electric shock can range from mild discomfort to severe injury or even death, depending on the voltage, the current path through the body, and the duration of exposure.

Understanding the risks associated with electric shock is crucial for anyone working in electrical maintenance or installation. Proper safety precautions, such as using insulated tools, wearing appropriate personal protective equipment, and making sure circuits are de-energized before working on them, are essential to mitigate this risk and ensure safety on the job.

While other hazards such as slips and falls, exposure to chemicals, and radiation exposure can also occur in various workplaces, electric shock remains a direct and significant risk associated specifically with electrical circuits.
