Fire door failures can occur for many reasons and ultimately put lives at risk.
These failures are often identified during fire door inspections as part of wider fire safety and building safety responsibilities.
UK inspection data highlights that a significant 75% of fire doors in the UK fail to meet required safety standards, commonly due to excessive gaps, poor maintenance, or improper installation.
Understanding common fire door faults, how they occur, and why they matter is essential to maintaining effective fire resistance and, of course, saving lives.
Why Fire Doors Fail More Often Than Expected
Fire door failures are more common than many people expect during fire safety risk assessments and often relate to inspection failure rather than obvious damage.
Fire doors are typically installed in high-use environments and are opened, closed, and impacted daily, leading to gradual wear on closers, hinges, alignment, and door frames.
Unplanned alterations such as new flooring, cable runs, or hardware changes can also compromise fire resistance if not assessed correctly.
Human factors play a significant role, with a lack of awareness and deferred maintenance allowing minor faults to worsen over time.
These issues frequently contribute to fire door inspection failures when assessed against current fire safety regulations.
Common Fire Door Failures
The following fire door failures are most frequently identified in real buildings during inspection.
Fire Doors Not Closing Properly
A fire door that cannot self-close cannot contain fire or smoke.
- Failed or poorly adjusted door closers
- Misaligned hinges
- Doors catching on flooring
- Door frame movement affecting closure and fire resistance
These issues can result in compromised escape routes during a fire.
Damaged or Incorrect Seals
Intumescent strips and fire door seals are designed to restrict the spread of smoke and heat.
- Missing seals
- Incorrect seal specification for the fire rating of the door
- Painted over or damaged seals
Seal failure allows smoke leakage in the early stages of a fire, reducing available evacuation time.
Excessive Gaps or Poor Door Alignment
Fire doors with excessive gaps or poor door alignment will not perform as tested.
- Poor installation
- Gaps exceeding permitted limits
- Initial misalignment affecting latch engagement
This allows fire and smoke to spread more quickly and directly affects the fire rating of the door.
Incorrect Hardware and Door Components
Fire doors must be maintained as a complete, tested system, and incorrect hardware or components can significantly limit performance.
- Non fire-rated or incompatible hardware
- Unverified component replacements
- Ad hoc repairs compromising performance
These issues can result in a loss of certified fire resistance and fire stopping capability.
Locked or Misused Fire Doors
Locked or misused fire doors cannot operate correctly, even if all other components are functional.
- Doors left open for convenience
- Doors locked and not released
- Situations where locking a fire door may be illegal
Locked or obstructed fire doors restrict escape routes and are a common issue identified during fire door maintenance and inspection activity.
Why Fire Door Faults Put Lives at Risk
Fire door faults allow fire and smoke to spread beyond intended compartments, increasing risk to life.
- Compromised protected escape routes
- Reduced time for safe evacuation
- Increased smoke exposure for occupants
- Greater risk to emergency responders
Multiple small faults can collectively result in a failure to achieve the required fire resistance in an emergency.
Regular inspection and maintenance are legal requirements under legislation such as the Regulatory Reform (Fire Safety) Order 2005, and staff fire safety training plays an important role in preventing misuse and inspection failure.
