I am a shop teacher in the St Louis area and I am in the process of previewing the safety week videos. The videos from the early 90’s that I use are still valid, but they are certainly fashion dated. I too have learned a lot and enjoy showing the Marc Adams videos to all of my classes. However on the miter saw, I strongly recommend a persons hands not being anywhere on the metal table surface of the saw. The reason for this is a person gets comfortable with their left hand on the left side of the table. That is great for 90 degree cuts. However when a 45 degree cut to the left needs to be made, the operator holds the board in the same manner with their hand on the left side of the saw and unfortunately the blade can come in contact with the thumb or more. I have a safety video of 2 injured persons telling their stories, and that was the case in both situations. I require that the clamp be used and no exception to the rule about hands on the metal area. If it can’t be clamped, then it is too small to cut, use the band saw instead.
At one point in the video, Marc clamps the wood and makes a cut. Big NO-NO when he puts his left hand between the clamp and the blade. There is a minimum of 3” margin of safety (danger zone). His left hand was definitely in violation of this.
Another good reference for power tool safety is the Power Tool Institute. They offer a free DVD for power tool safety. It is mostly geared for instructors and safety officers of companies. http://www.powertoolinstitute.com/
