Key Fire Door Issues and Solutions

Fire doors are one of the most important passive fire protection measures in any building, yet surveys consistently reveal that a significant proportion fail to meet the required standard. Common issues include damaged or missing intumescent strips, incorrect gaps between the door and frame, broken or absent self-closing devices, and the use of non-fire-rated hardware. Each of these defects can compromise the door's ability to contain fire and smoke, potentially turning a 30-minute barrier into one that fails within minutes.

The solutions are often straightforward but require diligence. Intumescent strips and smoke seals should be inspected regularly and replaced if they show signs of damage or paint contamination. Door gaps should be checked against the manufacturer's specification — typically 2-4mm around the head and jambs. Self-closing devices must be tested to ensure the door latches fully into the frame without manual assistance. Where hardware has been replaced, it is essential to verify that hinges, locks, and handles are fire-rated and compatible with the door's certification.

Building owners and facilities managers should implement a routine fire door inspection programme, ideally every six months, in line with the guidance in BS 8214. The Regulatory Reform (Fire Safety) Order 2005 places a legal duty on the Responsible Person to maintain fire doors in proper working order. Failure to do so can result in enforcement action, and in the worst case, criminal prosecution following a fire.
