Close this Door At Night - Safety Signs by Caledonia Signs

Remind occupants to shut specific doors—usually fire doors—before going to bed or leaving a building unattended overnight. This simple action helps prevent the spread of fire and smoke if a fire starts while people are sleeping or the building is unoccupied. Closed doors slow the spread of flames, protect escape routes, and give occupants and emergency services more time to respond.

These signs are especially valuable in residential settings where people sleep, such as hotels, care homes, apartment blocks, dormitories, and staff accommodations. Fires that occur at night are particularly dangerous because people are less alert and may not notice danger until it's advanced. A closed door can mean the difference between life and death in such situations.

The signs should be installed on or directly above key internal doors, particularly fire doors in corridors, kitchens, communal areas, and stairwells. Placement should ensure the sign is visible to anyone responsible for nightly safety checks, such as staff or residents.

Incorporating “Close This Door at Night” signs into a building’s fire safety routine is a simple but powerful precaution. It reinforces good habits, supports passive fire protection, and contributes significantly to occupant safety—especially during the most vulnerable hours of the day.
