What should be the initial step when setting up a mobile crane near power lines?

• A. Evaluate the weather conditions
• B. Establish a safe work zone
• C. Communicate with the crew
• D. Determine the voltage of power lines

Answer: (D)

The initial step when setting up a mobile crane near power lines is to determine the voltage of the power lines. Knowing the voltage is crucial because it dictates the required safety clearance distances and helps evaluate the potential hazards associated with the operation of the crane in proximity to the power lines. Understanding the voltage allows the crew to implement the appropriate safety measures to protect both personnel and equipment from electrical hazards. Evaluating weather conditions, establishing a safe work zone, and communicating with the crew are all important steps in the setup process, but they are secondary to determining the voltage. Without this crucial information, the other safety precautions may not be adequately tailored to the specific risks presented by the power lines. Hence, establishing a safe working environment must be based on an understanding of the electrical background.
