Print your own safety signs!
Safety signs can be a big expense for any business, but they’re often necessary for compliance with state and federal regulations. Sometimes you need to put up a sign to hold you over until you can order the real thing: aluminum, reflective, the works. Some sign companies have put up free versions of signs that you can use as temporary substitutes for important safety signage.
Of course, almost anything you make with a home or work printer is unlikely to be compliant with regulations if an inspector comes knocking and there’s required signage, but sometimes you need to designate a confined space, electrocution danger or chemical hazards in a hurry, and it’s better to have a self-printed sign than no warning at all. In that case, printable (and often customizable) signs should do the trick until your order comes in.
