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.

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.
