When operating a crane, what must an operator do if the hoist line makes contact with an energized power line?

When a hoist line makes contact with an energized power line, the most appropriate action for an operator to take is to switch the crane off immediately. This is crucial because the crane can become energized, posing significant risks, including electrocution to the operator and any nearby personnel. Stopping operations promptly helps to prevent further movement of the equipment, reducing the risk of additional accidents, and allows for a safer response to the situation.

While it might seem logical to continue operating the crane with a reduced load, this could still endanger the operator and others since the crane may be at risk of becoming electrically charged. Similarly, replacing the entire spool of wire rope would not address the immediate dangers posed by the live wire, and calling for assistance without taking action may delay critical safety measures that need to be implemented right away. Therefore, stopping power to the crane is the safest first step in this scenario.
