Smoke Door Keep Shut - Safety Signs by Caledonia Signs

A "Smoke Door Keep Shut" sign is used to instruct building occupants and staff to keep specific doors closed at all times to prevent the spread of smoke and fire in the event of an emergency. These doors are part of the building's passive fire protection system, and keeping them shut is essential for protecting escape routes, reducing smoke inhalation risks, and containing fire to its area of origin.

The primary reason to use this sign is to maintain the fire-resisting function of smoke doors. When left open, smoke can travel quickly through a building, reducing visibility, increasing toxic exposure, and compromising safe evacuation. By clearly indicating that these doors must remain closed, the sign reinforces good fire safety behaviour and helps ensure that the building’s fire containment measures function as intended during an emergency.

This sign should be placed directly on the smoke door itself, ideally at eye level, so it is clearly visible to anyone approaching or using the door. It is commonly found in corridors, stairwells, lobbies, and areas that separate different fire zones or compartments within a building. In multi-story buildings, they are often located between the main areas and staircases or escape routes.

Using a "Smoke Door Keep Shut" sign is also a requirement under many fire safety regulations and building codes, which mandate clear signage for fire and smoke doors. These signs help ensure that even in the absence of automatic closers or alarms, people understand the critical importance of keeping the door shut. Ultimately, this small but powerful sign plays a vital role in safeguarding lives and property in the event of a fire.
