A sawmill is a dangerous place no matter how old you are. I worked in a sawmill for a few years and had some close calls and I paid attention. I caught a 6 inch diameter log across the chest once.
I was working near a big industrial sized wood chipper when a log got to the chipper blades, caught and slammed against the shroud and busted off. I looked up just in time to see it spinning across the room at me and I jerked my head out of the way. It caught me across my chest and broke 4 ribs and cracked my sternum. I wore the flak jacket they provided after that.
The title of the article caught my attention. My brothers and I grew up in a logging/sawmill family. We owned the only sawmill that provided lumber for 100 miles and logged all our own timber. No one ever lost a finger, hand, foot, arm or had any other accident. My father "taught" safety to us. What a concept.... parents actually being allowed to be parents. The age of introduction to the mill was 9. We started shoveling shavings and sawdust out from under the machinery. By the time we were 12, we were full time loggers and mill workers. Every one of us has gone on to win performance awards in highly-skilled positions of life.
Ouch...I've had ribs broken before, but only one at a time - and it was hard to get a good breath with just that.
