No Exit Signs
No Exit Signs show staff, visitors and contractors that a door, corridor or passage must not be used as an exit route. They are best used in workplaces, schools, offices, warehouses and public buildings where a wrong turn could delay evacuation or create access confusion.
Where No Exit Signs Should Be Installed
You should install No Exit Signs on doors, corridors, stairwell returns, plant rooms and dead-end passages that could be mistaken for a usable exit. Position them at normal eye level where someone makes the route decision, not after they have already entered the wrong area.
No Exit Sign Viewing Distance Guidance
Choose the sign size around the approach distance, lighting and how quickly people must recognise the message. Larger formats suit corridors, reception routes and open workspaces; smaller signs suit close-range door faces and compact internal rooms.
| Size option | Practical viewing distance | Best use |
|---|---|---|
| H 420 x W 297 mm | Up to 10 metres | Large doors, corridors and public access routes |
| H 400 x W 300 mm | Up to 10 metres | Workplace entrances and larger restricted routes |
| H 297 x W 210 mm | Up to 7 metres | Standard internal doors and corridor decision points |
| H 210 x W 148 mm | Up to 4 metres | Close-range office doors and small rooms |
| H 150 x W 450 mm | Up to 8 metres | Wide door faces, narrow walls and horizontal mounting points |
What Clear No Exit Signing Helps You Prevent
After installation, this sign helps people make the right route choice earlier. That reduces wrong turns, limits unnecessary door use and supports clearer movement through buildings where visitors or contractors may not know the layout.

Installing No Exit Signs without creating route confusion
❌ Do not fit the sign after the person has already entered the wrong route
❌ Do not mount it too low where handles, furniture or people can hide it
❌ Do not place it beside an approved escape route where it could mislead
❌ Do not use it to identify a fire escape or final exit door
❌ Do not rely on it where access control or locked-door hardware is needed
❌ Do not use it to cover unclear building layouts without checking the route plan
✅ Install it at eye level on the approach side of the door or route
✅ Use the larger sizes where people view the sign across corridors or open spaces
✅ Keep the face clean, well lit and unobstructed after installation
No Exit Signs questions answered before you choose
What are No Exit Signs used for? No Exit Signs are used to show that a door, corridor or passage should not be treated as an exit route, helping you prevent wrong turns and route confusion.
Can I use this instead of a fire exit sign? No. This sign tells people not to use a route as an exit. Fire exit signs must direct people towards a suitable escape route using the correct emergency exit design.
Where should I position the sign? Fit it where the decision is made, such as on the door face or immediately beside the restricted route, so people can react before entering the wrong area.
Should I choose rigid plastic or self-adhesive vinyl? Use rigid plastic where you want a tougher screw-fixed sign. Choose self-adhesive vinyl for smooth, clean indoor surfaces where quick fixing is more practical.
Is the red prohibition symbol suitable for this message? Yes, the red prohibition symbol gives an immediate stop instruction, while the “No exit” wording removes doubt for people who may not know the building layout.

Helpful alternatives for no exit door and route notices
For wider fixing positions, select landscape no exit prohibition signs where the message needs stronger horizontal visibility. Good for gates, barriers and broad wall spaces near restricted exits.
For movable queue or route control, add a no exit stanchion sign where a temporary instruction is easier than wall fixing. Useful for receptions, events and changing pedestrian routes.
For repeated door messages, use six-pack no exit signs to keep instructions consistent across similar access points. Ideal when several doors need the same clear prohibition.
For a wider choice of matching products, review no exit safety sign options before choosing the final format. Helps you compare portrait, landscape and freestanding display needs.
