My daughter had a nasty accident in a gym, where a piece of equipment she climbed on collapsed to the ground from quite a height and she landed on her bottom very hard. The result was a crushed sciatic nerve, which left her leg completely dead, and a bruise, the like of which even the A&E doctor had never seen before. It covered her entire left buttock, about the size of a large tea plate, solid black and purple, and travelled down her leg for about 9 inches.
It turned out the equipment wasn't faulty, but she should have set the resistance higher than zero, which she didn't realise. Her argument was that if at zero it was dangerous, then it should be impossible to set it to this level and, with the help of a local firm of no win no fee solicitors, this argument won her a decent sum in compensation - not OTT, but she never wanted that anyway. She just felt so strongly that the gym management should not be allowed to get away with such a poor H&S approach.
