An off-the-wall tablesaw safety reminder

We all know that it's good safety practice to unplug your tablesaw before changing the blade. But sometimes we get in a hurry or forget. To remind myself, I hang the tablesaw's arbor-nut wrench on a nail near the the outlet that powers the tablesaw. When I need the wrench, I know to unplug the saw as well. The saw cord's plug hangs on two close-set nails so it's ready for me when it's time to plug it back in.
