At my dad's work, a warehouse worker somehow ran over another co-worker's leg and snapped it almost clean off and his other leg was just as broken. He told me in detail the panic that set in amongst the company because no one knew first aid and the guy was bleeding out or something, or just bleeding badly. He passed out, and all the managers and my dad(he's also a manager for a different department, I've never been sure what he does.) all remembered someone in another department knows first aid. The guy got out alive, but his life is forever ruined now, he's a cripple.
This only happened a few weeks ago.
