Although i have not got such a certification, i cant argue with that, In my case, i spent allot of time researching and talking to people about what to do, before i even started my first one, and i was careful to have all the right equipment, and spent a long time practicing with help in small situations to get myself up to speed.
While i was careful to do all this, i know how many don't, they just rip it out and go, without knowing what the dangers are (I know people who have used them many times without even knowing what the work Kickback meant) and so having such a measure in place would certainly help prevent such things, its not something i would be adverse to getting, and even though i have done allot of reading and practicing, now that you bring it up, its something i may well consider.
Some may call it too much, but i consider half a skull not enough!
