I can believe that though it's not a case in the UK yet that I'm aware of. My chainsaw has proved quite useful and hasn't bitten me but I treat it with the respect it deserves. A guy I know said we do have some similar regulations such as the abrasive wheel regulations which means he has to change the wheel on his workers angle grinders as he has done the abrasive wheel safety course. His point though was that anyone can go down the local DIY shop and get a 9" angle grinder and use it with no training. Hopefully they don't end up in A&E, affectionately known as the Black & Decker ward.
