It is from now on . Thing is, the outlet is in a really inconvenient spot, so I've also considered a locking cover for the switch plate. But yeah, that's a common sense rule I've had to remind myself of in recent weeks.
I'm equally lazy about running over to unplug the table saw before changing the blade. That's why I added the disconnect to the Unisaw. It's conveniently located and easy to use. I could even throw a padlock on it if I was worried about kids or visitors.
