Sometimes us guys need to be reminded when working around power tools. The same goes in the office when using a computer, copy machine, coffee machine or anything with power and a button. Hang this 12 1/2" x 10 3/4" sign anywhere that a little thought would be prudent. Made from heavy-duty 18 gauge steel and nicely finished in a baked enamel. Sure to look great for years to come. Made for you and me by a municipal sign company here in the U.S.A.
