Thats my intepretation also. Somethings are illegal in both (i.e. taking Class A drugs). I don't believe its illegal to use a dado head (and its all to do with guards etc), just when HSE recommend you don't do it, it gets difficult with insurance etc. , doubly so if you have an accident, and an order of magnitude more difficult if one of your employees has an accident.biglouie":262x5y45 said:I imagine its a health and safety in the work place, rather than my own personal health and safety in the workshop?
