Frequently asked questions
Why is it important to mark fire doors with this sign?
Fire doors are rated to contain smoke and flames for a set duration. Blocking or wedging them open defeats their protection. This sign reinforces the safety rule and helps prevent accidental obstruction in busy facilities.
What size should I use for a standard internal door?
Available sizes are 225 x 300,300mm. Viewing-distance notes are a practical selection aid, not a substitute for checking the approach distance, lighting, mounting position, wording and site risk assessment.
Can I install this sign on a glass fire door?
Yes. Vinyl is ideal for glass because it adheres cleanly without damaging the surface. Alternatively, use pre-drilled Colorbond or polypropylene mounted with stainless steel fixings for a more permanent installation.
Do trade customers get discounts on facility-wide rollouts?
Automatic volume pricing is 5–9 signs: 8% off, 10–24 signs: 15% off, 25–49 signs: 24% off, 50–99 signs: 32% off, 100+ signs: 40% off. The configurator is the source of truth and updates the unit price as quantity changes.
How do I know if my sign meets building code requirements?
Our Fire Door Do Not Obstruct Do Not Keep Open sign is designed to AS 1319 standards. We recommend checking your local building authority's signage schedule; if AS 1319 is referenced, you're compliant.
