Key Hazards
- Miscommunication between operator and signal person
- Signal person struck by equipment or loads
- Operator losing sight of the signal person
- Multiple workers giving conflicting signals
- Poor visibility from weather, darkness, dust, or obstructions
- Unclear stop signals during unsafe movement
2–3 Minute Talk Script
Signal persons help operators move equipment, vehicles, and loads safely when visibility is limited. Their role is important because the operator may not be able to see workers, obstacles, overhead hazards, blind spots, or the landing area.
The operator and signal person should agree on signals before movement begins. Standard hand signals, radio communication, and emergency stop signals should be understood by both people.
Only one person should give signals unless the crew has planned otherwise. Multiple people giving directions can confuse the operator and lead to sudden or unsafe movement.
The signal person should stand where the operator can see them and where they are protected from the equipment, load, backing path, swing radius, pinch points, and traffic.
If the operator loses sight of the signal person, the operator should stop immediately. Continuing to move without clear communication removes a critical safety control.
The signal person should stay focused on the task. Phones, side conversations, and other distractions can cause missed hazards or delayed stop signals.
Weather, darkness, glare, dust, noise, and obstructions can interfere with communication. Radios, lighting, spotters, or a different plan may be needed when hand signals are not clear.
Good signaling is about clear authority and immediate stopping when something is wrong. The signal person must be visible, focused, understood, and willing to stop the movement if conditions become unsafe.
Safety Reminders
- Agree on signals before movement begins.
- Use one designated signal person when possible.
- Keep the signal person visible to the operator.
- Stop immediately if visual contact is lost.
- Keep the signal person out of pinch points and travel paths.
- Use radios or other communication when hand signals are not clear.
- Make sure everyone understands the stop signal.
Ask the Crew
- Who is the designated signal person?
- Do the operator and signal person agree on the signals?
- Can the operator see the signal person throughout the movement?
- Is the signal person standing in a safe location?
- What is the emergency stop signal?
