Types of Signals
Hand, voice, audible, or new signals are allowed. The type of signals used and means of transmitting the signals to the operator (such as direct line of sight, video, radio, etc.), must be appropriate for the site conditions. All directions given to the operator by the signal person must be given from the operator's perspective.
Hand Signals
When using hand signals, the Standard Method must be used. Click on the video to see some of the Standard Method hand signals commonly used in hoisting.

Exception: Where an operation or use of an attachment is not covered in the Standard Method or the use of the Standard Method is otherwise infeasible, non-standard hand signals may be used. When using non-standard hand signals, the signal person, operator, and lift director (where there is one) must contact each other prior to the operation and agree on the non-standard hand signals that will be used.
Hand signal charts must be either posted on the equipment or conspicuously posted in the vicinity of the hoisting operation.
