All Contractors Must Hold Valid Permit to work on the site sign- 400 x 300mm

This sign reads plainly: “Permit to work. All contractors must obtain a valid permit to work on the site.” There’s no room for misunderstanding around the need for a work permit. Whether someone’s been on site a dozen times or it’s their first visit, this message is there to remind them what’s expected.

You’ll usually find this sign at site entrances or just before controlled work areas. It’s there to stop people if they do not possess the appropriate work permit.

The design does its job without overcomplicating anything. A bold white exclamation mark sits above the message. The blue background makes the white lettering easy to read—even in busy or low-light conditions.

The sign is built to last, too. It’s made from durable, weather-resistant material that stands up well in exposed outdoor areas. It can be screwed into place using pre-drilled holes or fixed using adhesive backing—whatever works best for your site setup.
