No offense meant, but it should be. Knowing what will happen if/when something goes wrong is something anyone who ever uses a piece of machinery should be taught before they're allowed to use it I've seen many accidents, (or after affects of), caused by guys who never stop to think about what's going to happen to them if something goes wrong. Not just for table saws, but for jointers, planers, shapers, you name it. If a machine has cutter that rotates at a high rate of speed, then kickback can occur. And for any person who stops, looks at the situation , and thinks about it for a minute or two, it's really just basic common sense. Don't stand in the direct path of the work piece. Is it 100% guaranteed to keep you safe? No, but it's the best and smartest way to improve your odds
As fas as terminology goes you can call it ejection if you like, but the rest of the industry calls it kickback, just something to keep in mind if your talking with others about it That's not to say Mr Mehler is wrong, I'm not familiar with him but I'm sure he is knowledgable. Just that there is certain terminology that's the accepted norm and in 20 years using machinery, working with other woodworkers and in other shops, I've never heard the term ejection used in that way
OK I'll get off my soap box for now I really don't want to sound so preachy, but when there is an actual debate over something that in the industry is considered proper technique 101…...
