Good preparation makes all the difference. Make sure you know what you have to do, familiarise yourself with the procedures and ensure that your work permit is in order. However, situations can change at any moment even if you are properly prepared. And in turn, this could create new risks. So just before you start work, always carry out a Last Minute Risk Analysis (LMRA).
