I think I've done my own version of that....a dozen times!
Slowly I am becoming a pessimist...I mostly catch other people leaving things 'out...just for a minute', I'm not nearly as good at catching myself.
Now I try to play the sesame street game " what happens next!?!?"
...if I leave my table saw outside, I unplug it in the garage...so there's no way a kid can come up and turn it on.
If something is left on the garage floor ( project #235 in progress) I try to remember to unplug
the garage door opener motor, so NO-ONE can get in!
some of you industrial machinists and mechanics probably do WCB required lockouts all the time, but it's sure hard to remember at home, or even on the field, when you're working on the plane yourself, right?
be safe. parts can be replaced. Wives, much more difficult!
