How should you signal the crane operator to lower the boom and raise the load?
AI Explanation
The correct answer is B) Extend arm with thumb pointing downward and flex fingers in and out.
This is the correct signal according to the Standard Hand Signals for Controlling Crane Operations established by OSHA (Occupational Safety and Health Administration). The downward thumb pointing and flexing fingers signal specifically indicates to the crane operator that they should lower the boom and raise the load. The other options do not match the standard hand signals for this particular crane operation.
