One of the guys who works with me is in hospital with 3rd degree burns after his Vape exploded in his pocket and set fire to his clothes. He is in a serious condition and will need skin grafts and they are monitoring the condition of his leg which is in a really bad state. The root cause is being put down to the battery shorting (I know nothing of Vapes or their design).

I'm sure that people will trivialise this but it's a genuine warning, I've seen the photos, the injuries are horrendous and he's going to need major treatment for months to come!
