Question 1

What hand signal is used to instruct a crane operator to raise the load?

Accepted Answer

Finger pointing up with a circular motion of the forearm and hand

Answer

Material stacking height is limited by the stability and weight characteristics of the materials to ensure stacks do not tip over, which could injure workers.
