What is the hand signal to raise tines?

Choosing the signal that indicates to raise tines reflects an understanding of standard hand signals used in construction and hoisting operations. The correct answer, which involves having the forearm vertical and the forefinger pointing up while moving the hand in small horizontal circles, effectively communicates the action of lifting.

This specific signal is crucial for safety and clear communication between operators and signal persons, particularly in noisy environments where verbal commands may not be heard. By having the forefinger pointed upwards, it provides a clear visual cue to the operator that they should elevate the load, as the upward direction is universally recognized in the context of lifting. The small horizontal circle motion reinforces the instruction, ensuring it is easily distinguished as a directive to increase height rather than another action.

Effective communication in hoisting operations relies heavily on these visual signals to prevent accidents and ensure that everyone on site is aware of what the equipment operator is about to do.
