Authorized Personnel Only Danger Sign

Description

Some areas of a job site are off-limits even to your own crew. Hoist machinery, energized rooms, shaft access, chemical storage — places where entry requires training, not just a hard hat. The Authorized Personnel Only sign draws that boundary in the OSHA danger format, and posting it does double duty: it keeps untrained workers out of high-risk zones, and it documents that access was restricted if an incident ever puts your site under review. In the danger format, the message reads as policy, not preference — the difference between a door people respect and one they try.

Every sign is printed in-house at our NYC facility. Choose 12″ × 18″ for doors, or 18″ × 24″ and 24″ × 36″ for gates and open approaches, on aluminum in 0.40, 0.63, or 0.80 gauge or 0.60 styrene. UV- and weather-resistant inks hold up on a roof-access door as well as they do in a basement mechanical room — this is a sign many contractors leave in place after turnover.

Ordering takes a minute: size, material, quantity. Delivery runs 2–3 business days across the five boroughs and Long Island, with 24-hour rush on most orders. Building managers and GCs posting every restricted door in a property can set up a contractor account for volume pricing and one-call re-orders.

Pair it with our High Voltage Keep Clear Danger Sign on electrical rooms, where both warnings belong side by side.

FAQ

What counts as an area needing an Authorized Personnel Only sign?

Any zone where entry requires specific training or authorization — mechanical and electrical rooms, hoist and rigging areas, roof access, and storage for hazardous materials.

Can this sign stay up after construction ends?

Yes — the aluminum versions are built for permanent installation, and the OSHA danger format remains the standard for restricted areas in occupied buildings.
