Two that I can remember. #1, like some of the others, low attic work, clear out to the soffit edge, trying to drill down to drop a switch leg. I was using a Milwaulkee right angle drill with an auger bit. Barely enough room to set drill, let alone push down on it. Had it basically right infront of my face. Drill bit hit a nail. drill torqued around and hit me in the jaw. Out for at least 30 seconds, maybe more. No fun.
2nd story. Had to crawl under our local airport FBO office, to remove some old conduit. About 4' of clearance, but alot of old water & sewer piping, and heat ducts in the way. Had to go over and under most of these. Got to about 20' from where I needed to go, and guess what I saw/heard. Baby rattlesnakes!!!. Where the baby is, are the adults around? I whistled to see if any adult snake would answer (?) and said a fast prayer. I'm still here, so you can guess I didn't encounter anymore snakes. I just won't be going back under there!!!
