Fire doors are a critical component of any building's fire safety strategy. They are designed to contain fire and smoke for a specified period, giving occupants time to evacuate and limiting the spread of damage. But fire doors only work if they are in good condition and properly maintained. Here is everything you need to know about fire door replacement.
What Is a Fire Door?
A fire door is a specially constructed door designed to resist the passage of fire and smoke for a defined period — typically 30 minutes (FD30) or 60 minutes (FD60). Fire doors are required by law in many types of buildings, including:
- Houses of multiple occupation (HMOs)
- Flats and apartment buildings
- Commercial and office buildings
- Schools, hospitals, and public buildings
- Hotels and guest houses
When Does a Fire Door Need Replacing?
Fire doors should be inspected regularly and replaced when they show signs of damage or deterioration. Key indicators that a fire door needs replacing include:
- Gaps around the door: A gap of more than 3mm between the door and frame compromises fire resistance
- Damaged seals: Intumescent seals that are missing, damaged, or incorrectly fitted
- Damaged door leaf: Cracks, holes, or significant damage to the door itself
- Incorrect hardware: Missing or incorrect hinges, closers, or locks
- Door does not close properly: A fire door must close fully and latch without assistance
- No certification: Doors without a visible fire door certification label
Legal Requirements
Building regulations and fire safety legislation require fire doors to be maintained in good working order. Landlords and building owners have a legal duty to ensure fire doors are compliant. Failure to maintain fire doors can result in prosecution and significant fines.
