Safety on the Job Site

Yesterday I had a subcontractor rush up to me and say I need to go to the hospital. After putting down my tool and whipping around to see what happened I rushed him to the ER. What had happened was he put his finger near the table saw blade and knicked the end of his thumb. This blog is about job site safety on a table saw. If you are using an old table saw like this subcontractor make sure you always use a push stick, the blade is sharp, the fence is straight, the wood is flat, and free of knots. Can you think of any more ways of preventing such accidents from happening?
