Question: During a multi-crane lift, the primary crane operator observes that the secondary crane's load line is swinging uncontrollably due to wind. The secondary crane operator does not seem to notice. What is the most appropriate action for the primary operator to take according to general safety protocols and CSA Z150?

Answer options:

• Continue their own part of the lift, as it's the other operator's responsibility. ✅ Immediately contact the secondary crane operator via radio and alert them to the hazard.
• Shout warnings to the ground crew to move away from the swinging load.
• Increase their own hoist speed to complete their part of the lift faster.

Correct answer: Immediately contact the secondary crane operator via radio and alert them to the hazard.

Explanation: In a multi-crane operation, effective communication is critical. The primary operator has a duty to alert the secondary operator directly and immediately to the hazardous condition to ensure the safety of all personnel and equipment, as per CSA Z150 guidelines for multi-crane lifts.
