Fire Door Inspections: The Ultimate Compliance Checklist for Facility Managers

In any hospital, school, or commercial building, fire doors are your absolute first line of defence. They are engineered to compartmentalise a building, holding back fire and toxic smoke just long enough for occupants to escape and emergency services to arrive.

However, they are also the single most common failure point we see during compliance audits. A fire door that is wedged open, damaged, or improperly fitted is no longer a life-safety device; it is just a heavy piece of wood.

Under the Regulatory Reform (Fire Safety) Order 2005, and reinforced by recent updates like the Fire Safety (England) Regulations 2022, facility managers and "Responsible Persons" have a strict legal duty to ensure all fire doors are routinely maintained.

To help you stay on top of your daily and weekly walkthroughs, here is a practical, 5-point compliance checklist for your fire doors.

The 5-Point Fire Door Checklist

During your routine facility walks, every fire door should be able to pass these five fundamental checks.

1. Certification and Signage: Check the top edge or side of the door for a certification label or plug (such as BM TRADA or BWF-Certifire). Additionally, ensure the correct mandatory signage is firmly attached (e.g., "Fire Door Keep Shut").

2. The Gaps: The gaps around the top and sides of the door must be consistently less than 3mm when the door is closed. The gap at the bottom of the door can be slightly larger (usually around 8mm to 10mm), but this depends on the specific door's certification.

3. Intumescent Seals: Open the door and look at the edges of the door and the frame. You should see thin strips running down the sides and top. These are intumescent seals that expand in the heat of a fire. They must be continuous, free from damage, and securely fitted.

4. The Hinges: A standard fire door must have a minimum of three hinges. Check that all hinges are firmly fixed, with absolutely no missing or loose screws. If the door is dropping or catching on the floor, the hinges are likely failing.

5. The Closing Mechanism: Open the door halfway, let it go, and watch it close. It must close completely and firmly onto the latch on its own power, without sticking on the floor or the frame. A fire door that doesn't close on its own is completely ineffective.

Important Note: The "3mm rule" for gaps is incredibly strict. To put it in perspective, a £1 coin is roughly 3mm thick. If you can slide a £1 coin into the gap between the door and the frame, the gap is too large and the door will fail to stop smoke.

When a Visual Check Isn't Enough

This checklist is an excellent tool for your in-house maintenance team to spot obvious, day-to-day hazards. However, it does not replace your legal requirement for formal, professional inspections.

Facility managers often find themselves out of their depth when dealing with older buildings, retrofitted doors, or subtle structural shifts that compromise a door's integrity. An untrained eye cannot accurately assess whether the correct fire-rated glass is installed, if the letterboxes contain proper intumescent liners, or if the door frame itself was installed with the correct fire-stopping foam.

Failing to identify these hidden faults leaves your building unprotected and leaves you legally liable if a fire occurs.

Remove the Liability from Your Shoulders

Do not leave your building's compliance to chance. If you have noticed failing hinges, excessive gaps, or if you simply cannot remember the last time your fire doors were formally assessed by a certified professional, it is time to act.
