Fire Door Keep Shut - Safety Signs by Caledonia Signs

An essential safety sign used to indicate that a specific door must remain closed to prevent the spread of fire and smoke. Fire doors are built to resist high temperatures and create compartments within a building, helping to slow the progression of fire and protect escape routes. Keeping these doors shut is critical to maintaining their effectiveness, and the disk serves as a constant visual reminder to building occupants of this life-saving requirement.

Affixed at eye level on both sides of a fire door so they can be easily seen regardless of the direction someone is approaching from. The clear, directive message helps to eliminate confusion during emergencies, reinforcing the door’s purpose and ensuring users don’t prop it open or leave it ajar.

These fire door disks are more durable and securely mounted using screws. This makes them much less likely to be removed, damaged, or fall off over time. Their hard-wearing construction ensures long-term visibility and reliability—key elements in maintaining proper fire safety protocols throughout a building's lifetime.

Commonly found in commercial buildings, hospitals, schools, apartment blocks, and industrial facilities. They are especially necessary on doors that lead to stairwells, corridors connecting fire zones, or rooms with increased fire risk such as electrical cupboards and boiler rooms. In each case, the goal is to isolate fire and smoke to a contained area, allowing more time for evacuation and reducing property damage.
