What is one of the key safety measures when operating cranes near electrical sources?

Maintaining established clearance distances is essential for safety when operating cranes near electrical sources. This measure is crucial because electrical hazards can arise from overhead power lines or other electrified equipment in proximity to the crane's operation. If a crane boom or load inadvertently makes contact with an electrical source, it can result in severe electrical shock, injury, or even death to the operator and nearby personnel. Establishing and adhering to these clearance distances minimizes the risk of such accidents by ensuring that the crane and its components remain a safe distance away from any potential electrical hazards.

While using cranes with shorter booms may seem safer, it does not necessarily ensure compliance with electrical safety regulations or the prevention of accidents caused by proximity to power lines. Similarly, while personnel wearing helmets is a good safety practice, it does not directly address the hazards posed by electrical sources. Using manual signaling instead of radios may arise from a desire to reduce electrical interference, but it is not a guaranteed solution for electrical safety concerns. Thus, maintaining established clearance distances stands out as a specific and proactive measure for protecting all individuals involved in crane operations around electrical sources.
