Mark entrances, employee-only work areas, and no-trespassing zones.

For indoor use, choose between vinyl and polyethylene signs. Polyethylene signs are more durable than vinyl signs, and they don’t chip or crack easily.

Aluminum signs are the best choice for long-lasting outdoor use. They won’t corrode if exposed to water, chemical splashes, or harsh weather. They’re also UV resistant, so they won’t fade in sunlight.

Signs that meet OSHA 29 CFR 1910.145 follow color and text standards for sharing information that is important, but not hazard-related.
