Question: During a multi-crane lift, the designated signal person suddenly loses radio contact with both crane operators. What is the required immediate action for all personnel involved in the lift, according to safety regulations?
Answer options:

Correct answer: All crane operations must immediately stop.
Explanation: Loss of communication during a multi-crane lift, or any critical lift, creates an uncontrolled and dangerous situation. All operations must immediately stop to prevent accidents until communication is re-established. Continuing the lift or attempting verbal commands in a noisy environment are unsafe.
