Signals
A crane operator often needs a signal person to operate safely. A signal person must be provided:
A crane operator often needs a signal person to be able to operate safely.
- when the point of operation, meaning the path the load travels or the area where the load is placed, is not in full view of the operator;
- when the equipment is traveling and the operator's view in the direction of travel is obstructed; or
- when, due to site-specific safety concerns, either the operator or the person handling the load determines that it is necessary.
During operations requiring signals, the ability to transmit signals between the operator and signal person must be maintained. If that ability is interrupted at any time, the operator must safely stop operations until signal transmission is reestablished and a proper signal is given and understood.
Only one person may give signals to a crane/derrick at a time, though any person may give an emergency stop signal.
