Fire Protection Door - Do Not Obstruct - Safety Signs by Caledonia Signs

An important fire safety notice used to ensure that fire doors and the areas around them remain clear at all times. Fire protection doors are designed to contain smoke and flames during a fire, helping to prevent the spread of fire between different parts of a building. The sign reminds occupants and staff that these doors must not be blocked, wedged open, or obstructed in any way, as doing so can compromise the building’s fire safety system and put lives at risk.

Using this sign helps maintain compliance with fire safety regulations and building codes, such as those outlined in the Regulatory Reform (Fire Safety) Order 2005 (UK) and similar international standards. It ensures that fire doors can close automatically and function correctly during an emergency. Keeping fire doors unobstructed also aids firefighters by preserving compartmentalisation and protecting escape routes, which are critical for safe evacuation.

Placement of this sign is essential for effectiveness. It should be installed directly on or near the fire protection door, as well as in nearby areas where objects might be placed that could block the doorway. In larger buildings, additional signs may be needed along corridors or in storage zones adjacent to fire doors to reinforce the message. The sign must be clear, durable, and visible even in low-light conditions — often using reflective or photoluminescent materials.

Additionally, displaying this sign reinforces a culture of safety awareness and responsibility among staff and building occupants. It serves as a constant reminder of the importance of maintaining clear access to fire safety features and complying with safety protocols. Over time, the consistent use of such signs helps reduce fire hazards, ensures smoother evacuations, and demonstrates the organisation’s commitment to protecting people and property.
