Some really lousy engineering there. Or someone didn't read the product specs on those racks.
One of the comments after the vid identified the location as Shropshire, England. Turns out that was cheddar cheese on those racks. One guy was trapped for 8 hours but was rescued unhurt, or mostly unhurt one would think. Imagine the process of salvage. A lot of the stuff was likely not damaged too bad but if the packaging was damaged, then what?
One imagines that warehouse managers took a long look at this debacle.
