NCCCO Signalperson case studies
NCCCO Signalperson · Put your knowledge to work in context.
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. To earn it, candidates must be at least 18 years old, comply with CCO's Substance Abuse Policy and Code of Ethics, and pass both a Written Examination and a Practical Examination; the two may be taken in either order, with 12 months allowed to pass the second one after passing the first. The written test is 60 multiple-choice questions in 60 minutes and spans hand signals, voice/radio signals, crane dynamics and operations, and the signalperson responsibilities described in OSHA 29 CFR 1926.1428. The NCCCO Signalperson case studies are 5 cases and about 3,753 words.
