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.

The label on a machine and the sign on the wall share signal words and colours but belong to different standards, with different owners and different replacement duties. This guide contrasts ANSI Z535.4 and Z535.2 point by point, then walks the relabelling of a rebuilt machine whose original label set was lost to paint.
