NCCCO Signalperson study guide
NCCCO Signalperson · Work through your exam, one topic at a time.
The CCO Signalperson certification is a nationally recognized, internationally accredited credential for workers who direct crane movements using hand signals and voice or radio signals. It is intended for signalpersons who are trained and who will actually use those signals during crane operation, across industries such as construction, steel erection, utilities and crane rental. The NCCCO Signalperson study guide has 4 sections and about 1,590 words.
01Hand Signals
Hand signals are the default language between signalperson and operator, and OSHA expects the standard signals for the crane type unless the operator and signalperson have agreed on an alternative the operator clearly understands.

Radio and voice communication is used when the operator cannot see hand signals - blind lifts, long booms, walls, or a signalperson who must reposition out of sight.

A crane’s rating is not a single number; it is a chart of load moment - load multiplied by radius - limited either by structural strength or by tipping. Radius is measured horizontally from the crane’s center of rotation to the center of gravity of the load, not to the boom tip.

The signalperson is a qualified person, not just a person holding a radio. Under 1926.1428 the signalperson must (1) know and understand the signals in 1926.1419 through 1926.1422, (2) know and understand the type of crane being used and its limitations, including crane dynamics and rigging basics, and (3) be competent in applying the type of signals used on that job.
