Signalperson Certification Prep Curriculum
Crane types & components
Enough about booms, jibs, hoists and swing to understand what each signal asks the crane to do.
Principles of communication
One signal person at a time, clear sightlines, the emergency stop that anyone can give, and confirming the operator understood.
Basic hand signals
Hoist, lower, swing, stop and emergency stop, using the standard chart in Subpart CC's Appendix A.
Directional signals
Signalling from the operator's perspective, boom up and down, and coordinating travel.
Advanced signals
Telescoping, using the main versus auxiliary hoist, moving slowly, and dog everything.
Voice & radio procedures + exam prep
Voice signal structure (function, direction, distance or speed, stop), dedicated radio channels, and practice questions.
Hand Signals vs. Voice Signals
Hand signals work when the operator can see you clearly and the site isn't too busy. They are quick, universal and easy to confirm. Voice signals over radio take over when the load or landing point is out of the operator's sight, which is routine on tower cranes, rooftop sets and congested plants.
Each method has its own discipline. With hand signals, position matters: stand where you're visible, use one signal at a time and keep your movements distinct. With radio, use a dedicated channel, identify the crane, give the function, direction and distance, and keep talking so silence never gets mistaken for permission. The course drills both, because the practical exam will ask you to demonstrate them.
Whatever the method, agree on it before the lift starts. Mixing hand and voice signals mid-lift without a plan is a common cause of confusion.
Who Signals Cranes on the Job
Signalling is rarely anyone's full-time job title. It's a responsibility handed to whoever is closest to the load and best placed to see it.
- Riggers and rigging foremen
- Laborers assigned to lift crews
- Ironworkers and steel erectors
- HVAC and rooftop installers
- Plant maintenance crews
- Telecom and utility crews
Qualified vs. certified
Under OSHA 1926.1428, a signal person must be qualified either by a third-party qualified evaluator or by the employer's own qualified evaluator. A certification from NCCCO or NCCER — after passing a written and a practical exam — is a common way to document it. Compare the NCCCO signalperson overview and the NCCER signalperson overview.
When a Signal Person Is Required
OSHA calls for a signal person in these situations. Read the full rule to confirm how it applies to your lift.
| Situation | Why it matters |
|---|---|
| The point of operation is not in full view of the operator | The operator can't see the load or where it's going |
| The operator's view is obstructed in the direction the crane travels | Hidden people or objects in the travel path |
| Site-specific safety concerns make it necessary, per the operator or the person handling the load | Judgment on congested or hazardous sites |
What Signal Person Training Online Prepares You For
Signals that can't be misread
Crisp, standard signals given from where the operator can actually see you.
Radio discipline
Continuous communication on blind lifts so the operator always knows you're there.
Stopping a lift
Knowing when and how to stop, and how to restart once the problem is fixed.
