You just spent $200 on a fine for not having a construction in progress sign. A simple piece of metal could have saved you that money and a headache. OSHA requires these signs, but most people pick the wrong type and get hit with penalties.
Don’t let a missing sign cost you time and cash. The right sign keeps workers safe and inspectors happy. We’ll show you exactly what to buy and where to put it so you never pay a fine again.
Work in Progress Signs: Safety and Compliance Made Simple
Construction in progress signs fall into four categories: Danger, Warning, Caution, and Notice. Danger signs are red and white for immediate life-threatening hazards. Warning signs are orange for serious injury risks. Caution signs are yellow for minor to moderate injuries. Notice signs are blue or green for general information.
Most job sites need a mix of these. For example, a caution construction in progress sign works near active work zones, while a construction warning sign fits near heavy equipment. OSHA mandates that signs match the hazard level. Using a Caution sign where Danger is needed can lead to fines up to $13,653 per violation.
