Fire proof doors and internal fire doors are critical components of any building’s passive fire protection system, serving as barriers that prevent the spread of fire and smoke throughout a building. These specialised doors can mean the difference between a minor incident and a catastrophic event, protecting lives and property by maintaining vital escape routes during emergencies. Regular maintenance and inspection of your fire doors ensures they will perform as intended when needed most.<\/p>\n\n\n\n

Understanding Fire Door Maintenance Requirements<\/strong><\/h3>\n\n\n\n

The importance of maintaining fire proof doors cannot be overstated. Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person for any non-domestic premises has a legal duty to ensure all fire safety equipment, including internal fire doors, is maintained in ‘good working order’. This isn’t just a recommendation \u2013 it’s a legal requirement that, if ignored, could result in substantial fines or even prosecution.<\/p>\n\n\n\n

For residential buildings, the Fire Safety (England) Regulations 2022 introduced additional requirements. Buildings with two or more dwellings must conduct regular fire door inspections, with the frequency depending on the building’s height. In buildings over 11 metres tall, fire doors in communal areas<\/a> require checking every three months, while flat entrance doors need annual ‘best endeavour’ checks.<\/p>\n\n\n\n

The consequences of poor maintenance can be severe. A damaged or poorly maintained fire door may fail to contain fire and smoke, potentially leading to rapid fire spread, blocked escape routes and tragic loss of life. Beyond the human cost, failing to maintain fire doors properly could result in criminal prosecution, unlimited fines and devastating reputational damage.<\/p>\n\n\n\n

Essential Components to Inspect<\/strong><\/h3>\n\n\n\n

When maintaining fire proof doors, understanding what to inspect is crucial. Every component plays a vital role in the door’s ability to resist fire and smoke. Let’s examine each element in detail.<\/p>\n\n\n\n

Door Leaf and Frame<\/strong><\/h3>\n\n\n\n

The door leaf itself should be checked for any signs of damage, warping or holes. Even small damage can compromise the door’s integrity. The frame must be securely fixed to the wall with no visible movement when pressure is applied. Check that the door sits properly within its frame \u2013 it shouldn’t be twisted or distorted.<\/p>\n\n\n\n

Intumescent Seals and Smoke Brushes<\/strong><\/h3>\n\n\n\n

Intumescent strips for fire doors<\/a> are perhaps the most critical component for fire resistance. These strips, embedded around the door edges or frame, expand when exposed to heat, sealing the gaps between door and frame. Inspect these carefully for any damage, paint overspray or missing sections. If your doors are rated FD30s or FD60s (the ‘s’ indicating smoke protection), they’ll also have smoke brushes that prevent cold smoke from passing through \u2013 these should be intact and not excessively worn.<\/p>\n\n\n\n

Fire Door Closers and Hinges<\/strong><\/h3>\n\n\n\n

A fire door is only effective when closed, making the selection of appropriate door closers<\/a> essential. The door closer should be powerful enough to close the door fully from any angle, overcoming the resistance of seals and latches. Check that it closes at a controlled speed \u2013 not slamming but not too slowly either. Fire doors typically require three fire-rated hinges, which should be checked for wear, damage or missing screws.<\/p>\n\n\n\n

Gaps and Clearances<\/strong><\/h3>\n\n\n\n

Correct gap sizes are crucial for fire door performance. The gap between the door and frame should be consistently 3mm (\u00b11mm) at the top and sides. The threshold gap (bottom of door) should not exceed 10mm, though some manufacturers specify tighter tolerances. Use a gap gauge to check these measurements accurately \u2013 excessive gaps will allow smoke and flames to pass through, while gaps that are too small may prevent the door from closing properly.<\/p>\n\n\n\n
