Safe Operating Procedures and Communication
What this domain covers
Safe Operating Procedures and Communication tests control of the work zone, signal discipline, and stop-work decisions during driving.
Operating rules
- One designated signal person directs the operator. Anyone may give an emergency stop. The operator must stop when a signal is unclear or when a person enters the fall zone.
- Agree on radio channel and hand signals before work. Identify the signal person by high-visibility clothing or a distinct position.
- Keep the exclusion zone clear during driving, extraction, and pile cutoff. Never stand under a suspended pile or hammer, in the leads, or between the pile and a fixed object.
- Maintain communication with the rigger, lead spotter, and nearby trades. Stop in high wind, lightning, poor visibility, or when ground conditions change.
- Do not swing a pile over workers, public areas, or power lines. Use tag lines and controlled starts and stops.
Worked example
The regular signal person steps away and a worker with a radio gives a swing-left command. The operator does not move because the new person has not been designated. The operator stops, confirms the handoff on the crew channel, and resumes only with the designated signaler. This prevents two-signal conflicts and unexpected movement.
Traps
Accepting signals from anyone who waves; moving because a radio voice sounds familiar; allowing workers to steady a pile by hand as it lands; and continuing when the signal person is out of view.
