Although this incident took place in a big-box warehouse store, it could have happened in any number of industrial warehouses across the country. The presence of order pickers, shoppers, or others in a rack aisle is a top safety concern, in particular if the aisle on the other side of the rack row is being restocked. Most likely this accident was caused by a push from the opposite side of the racks.
In any case, a tragic accident was narrowly avoided by sheer luck.
If possible, these kinds of accidents should be guarded against with items such as rack safety nets or wire mesh safety panels. This isn’t always possible, since lifts may need access to both sides of a rack aisle.
Another thing you can do is try to remove pickers from aisles where trucks are working the other side. If they are executing each-pick or carton-pick from lower bays, is it possible to move those to their own area of the warehouse, away from lift truck traffic?
In the case of poorly constructed storage, it’s a matter of process. Inspect pallets before they go into the rack. Are they stacked for stability? Shrinkwrap or band them to shore them up. Don’t allow carton picks from those pallets if possible, as that can destabilize the load. If you must pick from them, bring them down, pick, re-balance, and restock them. That’s time consuming compared to a quick carton pick, but given what almost happened here, and what could happen any day in any warehouse, it’s a small price to pay.
You can also clear both sides of a bay when either side is being loaded or unloaded by forklift. This helps you keep people safe even if there is a spill. Of course training lift drivers to avoid these types of “push” accidents is mandatory, but you can’t count on training alone when there is this kind of danger to people in the next aisle.
