Question 654 Deck General

The correct answer is D) All of the above. The operator of a pedestal crane should shut down operations under any of the listed conditions - an approaching squall line, lightning in the vicinity, or a fire on the pier. These are all hazardous situations that pose risks to the safety of the crane operator and those in the immediate area. Crane operations should be suspended to prevent potential accidents or injuries when environmental conditions or emergencies threaten the worksite. The other options are incorrect because they do not cover all the relevant safety-critical situations that warrant a shutdown of crane operations.
