I am struggling to understand what you need from this question, but as I read it, the answer would be no. If I was to injure myself at work because I used a pump truck as a skateboard and smacked head on with a forklift whilst not wearing a hi-vis vest (which is policy in our place) I would not have a leg to stand on, so to speak. Not only has training taken place, I have signed to say that I have received adequate training. Just uiing this as an example. Got to go, off to play dodgems on the forklifts
