Safe Operating Procedures, Signals, and Load Handling

What the exam tests

This domain tests standard signals, signalperson authority, load control, travel and swing rules, and fall-zone protection. Expect questions on who may give signals, when to stop, and how to handle an uncontrolled load.

Core rules

  • OSHA 1926.1419 requires a designated signalperson when the operator cannot see the load or the signal is not clear. Hand signals follow ASME B30.5. Radio signals require clear channel discipline and a dedicated frequency.
  • The operator must obey a stop signal from anyone. If a signal is unclear or conflicting, stop and get clarification. Never move because someone assumes the operator saw a signal.
  • Know the load weight, center of gravity, rigging, chart capacity, travel path, and landing point before lifting. Use tag lines where needed to control rotation.
  • Do not side-pull, drag, shock-load, or lift over employees. Keep employees out of the fall zone. Use the horn and barricades when needed.
  • Free fall is prohibited unless the crane is designed for it and the employer meets OSHA 1926.1426. Anti-two-block devices must not be bypassed.

Worked example

An operator is lowering a load when the signalperson gives a slow-lower signal, but a worker walks under the load. The operator must stop, hold the load, and sound the horn; the signalperson must redirect the worker. The operator does not continue merely because the signal is 'legal' - the fall zone is not clear. If the load is 6,000 lb and the chart at the current radius allows 6,500 lb net, the lift is within capacity, but capacity does not authorize lifting over people. The stop is based on the hazard, not the chart.

Traps

  • Obeying only the designated signalperson and ignoring a stop signal from a worker.
  • Continuing a lift when the signal is unclear or the load is out of view.
  • Using a tag line as a substitute for a clear fall zone.
  • Bypassing the anti-two-block device to gain boom height.
  • Assuming chart capacity alone makes a lift safe when people are underneath.
