Fire Door Checks that are Important to Fire Safety

Fire doors are one of the most critical components of a building’s passive fire protection system. Designed to resist the spread of fire and smoke, they provide essential time for safe evacuation and help compartmentalise spaces to limit fire damage. Today, fire door compliance is not just a recommendation—it is a legal requirement across residential, commercial, healthcare, and industrial sectors. With safety regulations becoming increasingly stringent, regular inspection and maintenance of fire doors have become a cornerstone of responsible building management.

Whether you are responsible for a block of flats, a commercial office, a care home, or an industrial facility, your fire safety measures must include a clear policy for inspecting and maintaining fire doors. These doors are specifically rated to withstand fire, heat, and smoke for a designated period—commonly 30 or 60 minutes (referred to as FD30 or FD60), with higher ratings available for high-risk environments. Choosing a reliable fire door supplier is the first step, but ongoing checks are just as vital.

Why Fire Door Inspections Matter

Fire doors serve a dual purpose: they provide seamless daily access for occupants, and during a fire event, they form a vital part of the building’s defence. When closed—either manually or automatically—fire doors compartmentalise spaces, helping to contain fire and smoke within a specific area. This slows the spread of fire, providing valuable minutes for people to evacuate and for fire services to respond.

For this reason, fire door inspections are not optional. They must be carried out regularly—some buildings may require checks quarterly or even monthly depending on foot traffic and usage. A proactive approach not only ensures compliance but significantly enhances occupant safety.

Key Fire Door Checks for Safety Compliance

To maintain the effectiveness of fire doors, thorough checks should be performed during installation and at regular intervals throughout the year. Below are the critical areas of inspection:

1. Intumescent Seals and Door Gaps

Check for the presence and condition of intumescent seals. These strips are fitted into the door frame and are designed to expand when exposed to heat, sealing the gap around the door and preventing fire and smoke from passing through. Ensure:

• The seals are continuous, undamaged, and securely attached.

• The gap between the door and the frame is consistent and does not exceed 3mm.

2. The Closing System

Fire doors should remain closed at all times unless there is a valid reason to keep them open. In such cases, they must be equipped with a fully functioning automatic release mechanism that ensures the door closes when the fire alarm is activated. Furthermore, properly installed closers are essential to guarantee the door shuts effectively, helping to contain smoke and fire and protect escape routes.

3. Door Hinges

A compliant fire door must have a minimum of three robust hinges, all firmly fixed with the appropriate screws. Check that:

• Hinges are free from damage or signs of wear.

• No screws are missing or loose.

• Hinges are fire-rated where required.

Loose or damaged hinges can compromise the integrity of the door during a fire, preventing it from forming a tight seal.

4. Door Leaf and Frame Condition

Inspect the door leaf and surrounding frame for any signs of warping, cracking, or damage that could hinder performance. Doors that have been propped open repeatedly or forcefully shut may suffer from misalignment or deterioration.

• Ensure the door closes flush with the frame without sticking.

• Look for evidence of previous modifications or unauthorised hardware.

5. Glazing (if applicable)

Fire doors that incorporate vision panels or glass must have fire-rated glazing. Check for:

• Intact glazing beads and seals.

• Certification marks that confirm the fire rating of the glass.

• No cracks or damage to the glass or surrounding sealant.

6. Locks and Latches

Any locking mechanisms should not impede the door’s ability to close and latch fully. Ensure:

• The latch engages fully when the door is closed.

• There is no delay or resistance in closing.

• Only fire-rated hardware is used.

Locks or latches that stick or fail to engage properly compromise the door’s ability to contain fire.

7. Automatic Hold-Open Devices (Where Used)

If fire doors are held open during operational hours, they must have hold-open devices connected to the building’s fire alarm system. Upon alarm activation, the door must release and close fully and automatically. Regular testing is essential to ensure this function is working correctly.

8. Signage

Legally compliant fire signage must be visible and securely affixed to both sides of the door. Ensure:

• Signs read “Fire Door – Keep Shut” (or “Keep Locked” if applicable).

• Signage is not obscured by stickers, paint, or damage.

• Signage is made of fire-resistant material.

Clear signage helps ensure occupants know how to respond to fire safety procedures.

9. Certification Labels

Every certified fire door should display a permanent label (typically located on the top or side edge) detailing its fire rating and manufacturer details. During inspections, verify:

• The label is present and legible.

• The door is installed in line with manufacturer guidelines.

Missing or tampered labels may invalidate a door’s certification.

The Importance of a Maintenance Schedule

All fire doors should be part of a formal maintenance schedule. This should include:

• Routine visual inspections by on-site personnel.

• Professional inspections carried out by qualified fire safety professionals.

• Immediate repairs where defects or wear are identified.

Fire door inspections can be incorporated into broader fire risk assessments and health and safety audits. In many jurisdictions, building owners or responsible persons may be held legally accountable for non-compliance.

Final Thoughts

Fire doors are not just another piece of hardware—they are lifesaving devices that function as critical barriers against the spread of fire and smoke. When properly maintained, they preserve escape routes, reduce property damage, and save lives.

As someone responsible for fire safety risk assessments, you must ensure every fire door is regularly checked and kept in top working condition. Prioritising these inspections and working with a trusted fire door supplier will not only ensure compliance but also build a safer environment for everyone using the building.
