I'm a qualified first aider and fire marshall but would still be very careful when and where I put these in to practise!
You'd use common sense-not blankly refuse to use it in any situation. My point exactly
Well I certainly wouldn't stand idle but I'd assess the situation before I even contemplated involving myself into it if that makes sense?
See earlier post re: fitting kit into taxis but not having training so they will not be used. Common sense would be not fitting the kit, or fitting it and having training. In any situation, I could not have kit available and refuse to help due to being worried about being sued.
I have had some training-used to sell fire equipment and have first aid at work training, but if I had the kit in my daily vehicle and had no training, I would at least read the extinguisher instructions and first aid manual to be able to be of some use, rather than saying "ain't covered, ain't had the training..."
