Final answer:
Using insulated tools is the incorrect option for an operator trying to safely exit an unexpectedly energized crane. The 'one-handed' work technique is advised in high-power electric situations to prevent the risk of electrical current traveling across the chest and through the heart.
Step-by-step explanation:
The question pertains to the procedures an operator should follow when needing to leave a suddenly energized crane. In such situations, it is crucial for the safety of the operator to avoid actions that could lead to further harm. Of the four options provided, using insulated tools is not a corrective action for safely exiting the crane; rather, it pertains to working on or near electrical equipment to ensure the risk of electrical shock is minimized.
In high-power electric circuit scenarios, it is advised to work 'one-handed' or keep one hand in your pocket. This safety precaution is advised because it minimizes the chance of creating a complete electrical circuit across the heart, which could be lethal. If a person were to use both hands, there is a higher risk that an electrical current could pass from one hand to the other, potentially crossing through the chest area. By using a 'one-handed' technique or placing one hand in your pocket, you are reducing this risk substantially.
