Question: A signalperson is directing a critical lift in a noisy environment. The operator frequently asks for clarification or repeats commands. What is the most effective immediate measure the signalperson should take?

Answer options:

• Increase the volume of their voice and shout the command louder.
• Switch to pre-arranged horn signals for all commands. ✅ Stop the operation, re-evaluate communication methods, and consider an alternative like two-way radios with noise-cancelling features.
• Use more exaggerated hand gestures combined with verbal commands.

Correct answer: Stop the operation, re-evaluate communication methods, and consider an alternative like two-way radios with noise-cancelling features.

Explanation: If communication is frequently unclear or misunderstood, it indicates a breakdown in the communication process. The safest and most effective measure is to halt the operation, reassess the communication method, and implement a more reliable solution, such as proper two-way radios, as per CSA Z150 guidelines.
