Communication, Signals, Spotting and Pedestrian/Vehicle Separation
Communication
Reach stacker work is a team task. Agree signals before work starts - hand signals, radio, or both - and use a designated spotter where the operator's view is obstructed. Signals must be unambiguous and understood by all parties. If communication fails, stop.
Spotting
A spotter positions where the operator can see them and where they can see the load path - never in the load path or under the boom. The spotter's role is to guide, not to overrule the operator's judgement; the operator remains responsible for the lift.
Separation
Pedestrian and vehicle separation is the single most effective control against struck-by incidents. Physically separate where practicable (barriers, walkways, gates), mark and sign where not, and enforce. Reversing is a high-risk manoeuvre: use mirrors, cameras, alarms and a spotter.
Traps
- Questions offer "the spotter will warn pedestrians" as a substitute for physical separation - it is a lower-order control.
- A spotter standing in the load path is a hazard, not a control.
- Radio failure means stop, not "carry on carefully".
Rule of thumb
If you cannot see your spotter, or your spotter cannot see the load path, stop the lift.
