Custom wording does not create a custom exemption: a sign you wrote owes exactly the same class, colour, construction and wording duties as one you bought. This ten-step design checklist works through them in order, and names the defect that damages a sign set most, which is DANGER placed on a hazard that is merely potential.

No OSHA standard requires a second language on a safety sign, and OSHA has confirmed it requires no English either. What it requires is comprehension. This decision guide walks the branch points in order, from surveying who is actually exposed to choosing symbols over translation, and records why each choice is defensible.

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.

OSHA sets safety sign rules in two separate places, and the ANSI editions it incorporates run two to three revisions behind what vendors sell as current. This guide decodes the three sign classes at 1910.145(c), the specified colors, accident prevention tags, and the construction table at 1926.200, plus exit and aisle marking duties.
