OSHA-format and ANSI Z535 signs are both legally acceptable, for entirely different reasons. This guide compares the two sign faces element by element, explains what an ANSI compliant vendor badge does not tell a buyer, and gives five questions for choosing a system, with migration staging and purchase specification language.

The signal word on a safety sign encodes how certain the harm is, not how bad it would be. This guide defines all four ANSI Z535 signal words with their exact panel colors, shows where OSHA's three sign classes leave a gap at WARNING, and gives a clear two-question test for assigning the right header to any hazard you find.
