What must be ensured to avoid risk when operating mobile cranes near energized lines?

To avoid risk when operating mobile cranes near energized lines, ensuring effective grounding or implementing comprehensive safety measures is essential. This involves maintaining appropriate distances from live power lines and using equipment that safeguards against accidental contact. Safety measures might include using insulated tools or protective barriers and implementing a work zone plan that clearly delineates safe areas.

Grounding ensures that any unintended electrical current has a safe path to the ground, minimizing the risk of electric shock to operators and nearby personnel. Comprehensive safety measures also entail careful planning and risk assessment before operations begin, ensuring that all potential hazards are identified and mitigated appropriately.

While proper training for operators, placement of warning signs, and limiting the number of workers nearby are important practices that contribute to safety, they are insufficient on their own without robust grounding and comprehensive safety measures specifically designed to address the unique hazards presented by operating near energized lines.
