One more thing to consider with ANYone else in the shop: KICKBACK. I've had my encounters, imagine if it had missed me and hit one of my 5 year old grandkids in the face. Fortunately I don't work in the shop when they are visiting.
When I was young (8-10) I used to watch my dad in his garage shop. It was big enough for both the cars and his old Dewalt RAS. After the first time he had a kickback, I started sitting in the car to watch through the windshield it scared me so much.
