Ouch. Take a look at the video associated with this Amazon warehouse disaster in which a forklift drive nudges a shelving unit and the whole warehouse shelving system collapses like dominoes.
Be sure to watch the full one-minute video, not just the tiny clip.
It's not known when or where this occurred, nor the fate of the poor forklift driver. All I can say is, what happened to the notion of reinforcing these high shelves with bracing from the ceiling?
And you think your day is bad...
