What is a common hazard associated with working on live electrical systems?

The hazard of electrical shock is a significant concern when working on live electrical systems. Electrical shock occurs when a person comes into direct contact with an energized source, which can lead to severe injuries or fatalities. The degree of shock depends on various factors such as the voltage level, path of the current through the body, and the duration of the exposure.

Working on live systems means there is an ongoing risk of exposure to hazardous voltages, making awareness and adherence to safety protocols critical in preventing accidents. Proper personal protective equipment (PPE), training, and safety measures are essential to mitigate this risk and ensure a safe working environment when dealing with electricity. This focus on safety is paramount given that electrical hazards can occur unexpectedly, emphasizing the seriousness of avoiding such risks.
