Theoretically true. But I as yet cannot envision how a running chain would get to my left hand in any position but cutting with the saw upright and my hand on top of the handle, in which case the chain brake would likely engage before it could get to my hand. When the saw is horizontal, as in felling, my hand would not be behind the chain brake lever, but I don't see how the bar would get to my left hand in a felling position, even when bore cutting. I guess I have not seen the physics of all possible movements. Anyway, as an advanced amateur, not a pro, I try to avoid cutting situations I judge to be beyond my capabilities. I have hired pros for some jobs. Sometimes I barter the saw log for the services, and I take the tops for firewood. I recently did this for a white oak that got blown down. It had a sawlog of about 36" at the butt end and maybe 24" at the top end, about 36-40 feet long. It was attached to its root ball but pretty hung up among other trees, as it had a pretty full crown. (Probably why the wind blew it down.) I got close to 2 cords of firewood from the top. I figured it was a good deal, as the logger had to bring out a crew, a skidder, a loader and a log truck for one tree.Not my point. My thought was IF you had something happen that caused the chain to cause an injury to your hand, I doubt the chain brake would have been engaged. So, if you are using the gloves to protect your hand, the Class of PPE should be calculated on the chain speed without the brake engaged.
