Most safety professionals know there is an actual rationale as to when use DANGER, CAUTION, and WARNING signs and how these signs are color-coded; however, there are a lot facilities who may not have a safety professional who can offer this guidance as to when to use signs, how to use them and which one to use for the specific need. Hence, OSHA has a standard that provides us with some VERY SPECIFIC requirements regarding “Specifications for accident prevention signs and tags”. This OSHA standard is often overlooked, until OSHA issued a citation because a facility’s e-stop buttons were not red in color. My e-mail and phone lit up with questions about that posting, asking if it was real. I promise it was real and I even posted a snap shot of the actual citation. But 1910.145 requires so much more.
