The clipped rack upright and the bent beam
You are operating a reach truck in a 3.2 m aisle. While turning into the aisle, the rear of the truck clips the upright of a pallet rack at about 3 km/h. You hear a metallic sound. Looking up, you see that the lowest beam on that bay is bent downward by about 25 mm and the safety clip on one end is missing. A pallet of canned goods weighing about 900 kg sits on that beam at 2.5 m. No one is hurt. A small puddle of hydraulic oil, roughly 1 L, is spreading near the base of the rack. It is 13:45; your shift ends at 14:00 and the next operator starts at 14:00.

- Stop the truck, lower the forks, apply the brake and switch off. Do not drive away as if nothing happened; the rack may be carrying load through a damaged member.
- Check for injuries and for anyone under or near the bay. If the rack looks unstable, move people away rather than toward it.
- Barricade the bay, for example with tape and cones at a safe distance, and tag the rack 'DAMAGED - DO NOT USE'. The next person must not add or remove loads.
- Control the oil: contain it with absorbent, do not hose it to a drain, and mark the floor as slippery. Hydraulic oil is a slip hazard and an environmental issue.
- Report immediately to the supervisor and the rack inspector or competent person; do not wait for the shift handover.
- Inspect the reach truck for damage, and complete an incident and near-miss report before leaving. Hand over verbally and in writing to the next operator so the barricade is not removed overnight.
2. Explain why you should not simply remove the pallet from the damaged beam.

The beam is already deflected and one safety clip is missing, so its capacity is no longer the original rating. The 900 kg pallet may be partly supported by a member that has lost strength, and the load path may have shifted to the uprights or adjacent beams. Removing the pallet is not a neutral act: lifting it changes the load distribution, can release stored strain, and can cause the beam to drop or the rack to move. The reach truck also has to approach the damaged bay, putting the operator underneath the load.
The correct sequence is to isolate the bay, have a competent person assess the damage against the rack manufacturer's criteria, and then plan the unloading with the rack empty or supported as required. If the assessment says the bay must be unloaded, that is done to a method, not by 'just taking the pallet off'.
3. What should be recorded and reviewed to prevent recurrence?
Read the worked answer
Record the facts while they are fresh: time, truck number, aisle and bay number, direction of travel, speed, the damage observed (25 mm beam deflection, missing clip, upright contact), photographs, the oil spill and the clean-up, who was notified, and the barricade and tag numbers. Raise a maintenance work order for the rack and a separate one for the truck.
The review should ask why the rear of the truck contacted the upright: aisle width versus truck and load dimensions, corner geometry, floor markings, lighting, rack protection such as corner guards, operator sightlines with a reach truck, speed, and whether the turn was a normal manoeuvre or a shortcut. If the aisle is routinely tight, the fix may be layout or rack protection, not just retraining. I would also check whether other uprights show similar impact damage, because a single reported hit often means several unreported ones.
