it was just a little nudge, who built that thing http://www.discussworldissues.com/fo...ies/wacko1.gif

A 5 tonne truck at full acceleration is a touch more than a nudge! The way pallet racking is made is that if any of the vertical supports buckle due to a side impact, the down force of all the pallets on it crushes the weakened vertical support (You can see how the racking bulges before coming down) and this causes it to pull horizontally on the attached horizontal bars that the pallets sit on, and that then pulls on the next attached vertical support, of which buckles, and then its pulls on the next row of horizontal bars, and this buckles the next vertical support! It is literally like dominoes! One falls down, it takes the next one out, the only difference is that each dominoe is attached to each other!

Looks like over loading the shelves was part of the problem.

Nah, the ratings on that type of shelving is quite surprising - we use similar ones at work, and other places I've worked.

I've used it too, it didn't look that thin though.

Yeah, you won't be laughing when you find out that's over $100000 worth of vodka and cognac. Talk about party foul.

Now would be a good time to repost the Klaus safety video http://www.youtube.com/watch?v=cUwki29-rYQ
