OSHA fine for not wearing steel toed boots?

I tried to find this but such a pain in the ass from a mobile. Does anyone know the guidelines for fines for someone not wearing steel toed boots?

Thanks Duckster.

I dunno about OSHA’s official rules, but I know that 20 years ago when I worked a job that required safety shoes and eye goggles, the rule-- as stated by the department manager-- was simple:
“wear 'em or get fired”.
