Question: During a blind lift on a construction site, the crane operator loses radio contact with the signal person due to interference. What is the immediate and most appropriate action the crane operator should take?

Answer options:

• Continue the lift slowly, anticipating the next move. ✅ Stop all crane movement and secure the load.
• Use hand signals if the signal person is visible.
• Attempt to contact another signal person on a different frequency.

Correct answer: Stop all crane movement and secure the load.

Explanation: In a blind lift, continuous and clear communication is paramount. If radio contact is lost, the immediate and safest action for the crane operator is to stop all crane movement and secure the load to prevent accidents or uncontrolled movement. Continuing the lift without communication is extremely hazardous. While using hand signals could be an option if visible, the scenario specifies a blind lift where visibility would be limited or non-existent.
