A construction area sign warns the public and workers that they are approaching an active work zone, and it controls who can enter. OSHA 1926.200 requires accident-prevention signs to mark the hazards on a construction site, so posting them is part of compliance, not just good practice. Start with a Construction Area Keep Out sign at the boundary and build out from there using the full construction area signs range.
The most common construction area signs display core messages around access and PPE control. The most common are Construction Area Keep Out, Construction Area Authorized Personnel Only, Construction Area Hard Hats Required, and a No Trespassing sign for the property line. Most sites post a combination so the rule is clear at every approach.
Yes, but they are a separate system from the signs on this page. Road-facing work zones follow the Federal MUTCD, which OSHA adopts under 1926.200(g), and those signs are the orange diamond road-work, detour, flagger, and lane-closure signs. You will find them on our road construction signs page. The signs on this page are the OSHA and ANSI on-site area signs that control access and mark hazards inside the work area itself.
Yes. For a spot without a wall or fence to mount on, use a freestanding sign. We recommend the floor-standing Construction Area Keep Out sign at an open gate, or the No Entry sign, both of which stand on their own and move as the work moves. For marking the floor of an active area, see our construction area stand-up floor signs.
Heavy-duty aluminum is the best outdoor choice. It is rust-proof and weatherproof, and it holds bold graphics for years on an exposed site. For low light, dawn, or dusk work, choose engineer-grade or high-intensity reflective sheeting so the sign reads under headlights and work lights. Corrugated plastic is fine and economical for a short-term posting. For visibility from a distance, step up to our big construction signs.
Construction area signs are simple, direct warnings such as keep out or authorized personnel only, posted around the perimeter to control access. Construction site signs are the larger boards posted at the main entrance that list multiple rules, PPE requirements, and project information at once. Most jobs use both: area signs along the boundary and a site sign at the gate. Both live under our construction and job safety hub.
Yes. Start from a custom construction sign template to add your company name, a site-specific hazard, or contractor contact information.
