Summary:
Here are the key points from the video:
Aaron's accident:
He was making a drawer front and the piece got kicked back, sending his hand into the blade.
He made three mistakes:
He didn't use a push stick.
He pushed the piece with his hand instead of a push stick.
He didn't have his riving knife installed.
How to avoid table saw accidents:
Take your time and make sure you have everything you need before you start cutting.
Never let your hands go beyond the front of the blade without a push stick.
Don't stand directly behind the saw blade.
Set your blade height just taller than the material you're cutting.
Never reach over or across the blade to grab a piece.
Don't wear gloves or baggy sleeves or clothing around the table saw.
Always try to keep a blade guard or riving knife on the table saw.
Consider purchasing a saw stop, which has safety features that can help prevent accidents.
