It is never said too much; safety first. I always wear my safety glasses and hearing protection in the shop. I use push sticks to keep my fingers where they belong, on my hands. Let me tell you how even the most careful person is at risk. I was cutting a long board and did not have an outfeed stand for my saw. I leaned forward a bit to complete the cut and support the wood. As I straightened up my foot slipped and I hit the saw blade with my push stick. There is nothing like looking at a mangled push stick to make the lesson sink home. Without the push stick I would of been missing fingers. Do it the safe way, every time, no exceptions!
