Rick switch out the canisters on that mask to OV (organic vapor).
First rule if you are worried about bits hurting you is don't buy the Chinese ones. Buy a quality brand like Whiteside, Freud, CMT, Amana, Infinity, or Lee Valley. A bit won't come shooting out of a collet without warning. First they'll start to slip a little and ruin your cut. When that happens get a new collet. As said, wear safety glasses and hearing protection. Like Rick said, injuries from damaged bits are pretty rare. I don't remember a member telling us that happened in the 6+ years I've been on the forum.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
