Last night when I was starting up my new (to me) saws my son (4 yo) was nearby. I got it started and was so excited that for a few moments I forgot he was even around. I was revving the saw then turned around and he was gone. It freaked me out a bit because I realized I was not paying attention to where the tip was (which is right at head or neck level for him). I shut off the saw quickly and ran into the house and my son was screaming "are you done?" I guess the sound of the saw startled him and he went running into the house. I learned this lesson the easy way, with no injuries. Fortunately my son is very careful around power equipment, but not all young kids are. Just wanted to pass along a little reminder to be aware even if you are just tinkering in the shop.
