Fire Door Inspection Workflow: What to Track and How to Stay Compliant

Fire doors are among the most critical passive fire protection measures in any building. When correctly installed and maintained, a fire door resists the passage of fire and smoke for a rated period — typically 30 or 60 minutes — providing occupants with the time needed to evacuate and enabling the building's fire compartmentation strategy to function as designed. Yet fire doors are also among the most frequently deficient fire safety assets encountered during inspections and fire risk assessments. Propped open, damaged, incorrectly installed, or fitted with missing or degraded seals, fire doors in a failed state offer little more protection than a standard door. This guide sets out the regulatory framework, the inspection checklist, frequency requirements, and the practical workflow for maintaining fire door compliance using digital systems anchored to floorplans.

What Is a Fire Door

A fire door is a door assembly — comprising the door leaf, frame, intumescent strips, cold smoke seals, hinges, latch or lock, closer device, and any glazed panels — that has been tested and certified to resist the passage of fire and/or smoke for a specified duration. Fire doors are classified by their integrity period: FD30 doors provide 30 minutes of fire resistance, FD60 doors provide 60 minutes, and higher ratings (FD90, FD120) exist for specialist applications. The "S" suffix (e.g., FD30S) indicates that the door also provides smoke resistance when tested to BS 476-31.1.

Fire doors serve two primary functions within a building's fire strategy. First, they form part of the fire compartmentation system, preventing fire spread between compartments and protecting escape routes. Second, they protect specific high-risk areas — plant rooms, storage rooms, kitchens — from allowing a fire originating within those spaces to spread to occupied areas. Every fire door in a building has a specific role defined by the fire strategy, and its failure compromises the integrity of that strategy.

Regulatory Framework

The legal obligation to maintain fire doors arises from several overlapping instruments:

The Regulatory Reform (Fire Safety) Order 2005 — Article 17 requires the responsible person to ensure that fire safety measures (including fire doors) are maintained in an "efficient state, in efficient working order and in good repair." This is the primary enforcement mechanism, and non-compliance can result in enforcement notices, prohibition notices, or prosecution.

The Building Safety Act 2022 — For higher-risk buildings (residential buildings over 18 metres or 7 storeys), the Act introduces enhanced requirements for the management of building safety, including fire doors in common areas. Quarterly inspections of flat entrance doors and annual inspections of all fire doors in common areas are now statutory requirements for buildings within scope.

Building Regulations Approved Document B — Specifies where fire doors are required during the design and construction of buildings, including compartment walls, protected corridors, protected stairways, and rooms of special fire risk.

BS 476 Parts 20-24 — The traditional British Standard for fire resistance testing. BS 476-22 covers the fire resistance of non-loadbearing elements, including doors. Although largely superseded by European standards for new products, many existing fire doors in buildings were tested and certified under BS 476.

BS EN 1634-1 — The European standard for fire resistance and smoke control tests for door, shutter, and openable window assemblies. This is the current test standard for fire doors placed on the UK market.

BS 8214:2016 — Code of practice for the installation of fire doorsets. Provides guidance on correct installation practices, which directly affect the performance of the door in a fire.

Fire Door Ratings and Standards

Understanding fire door ratings is essential for specifying and inspecting doors correctly:

• •FD30 — 30 minutes of fire resistance (integrity). The minimum standard for most internal applications, including doors to protected corridors and stairs in residential buildings.
• •FD60 — 60 minutes of fire resistance. Required for higher-risk applications, including compartment walls separating different occupancies, and often specified for stairwell doors in taller buildings.
• •FD90 and FD120 — Used in specialist applications such as industrial premises, certain healthcare facilities, and high-rise residential buildings where extended evacuation times are anticipated.
• •"S" designation — Indicates the door has been tested for smoke leakage at ambient temperature (BS 476-31.1) and includes cold smoke seals. Commonly specified as FD30S for doors to protected corridors and stairs.

The fire rating applies to the complete door assembly — leaf, frame, ironmongery, glazing, and seals — as tested. Modifying any component (fitting a different lock, adding a letterbox, changing the glazing) without confirming that the modification has been tested as part of a compatible assembly can invalidate the fire rating.

The Fire Door Inspection Checklist

A thorough fire door inspection examines every component of the door assembly. The following checklist covers the items that must be assessed:

Door Leaf Condition

• •Is the door leaf free from damage, holes, splits, or warping?
• •Is the door leaf thickness consistent with the specified fire rating? (FD30 doors are typically 44mm; FD60 doors are typically 54mm.)
• •Is any face damage present that could compromise the core integrity?
• •Is the certification label or plug visible and legible?

Frame Condition

• •Is the frame securely fixed to the wall with no visible gaps between the frame and the surrounding structure?
• •Is the frame free from damage or distortion?
• •Is the gap between the frame and the wall properly fire-stopped?

Gaps and Clearances

• •Is the gap between the door leaf and the frame no greater than 3-4mm on the hanging and closing edges? Gaps exceeding 4mm may allow fire and smoke to pass around the door.
• •Is the gap at the threshold (bottom of the door) no greater than 8mm for doors without smoke seals, or 3mm where smoke seals are required at the threshold?
• •For double doors, is the gap between the meeting stiles within the specified tolerance?

Intumescent Strips

• •Are intumescent strips present and continuous around the full perimeter of the door leaf or frame (as specified by the door manufacturer)?
• •Are the strips undamaged, unpainted over (unless paint-grade strips are specified), and free from gaps?
• •Is the strip material consistent with the door's fire rating?

Cold Smoke Seals

• •Where required (FD30S or FD60S rated doors), are cold smoke seals present and continuous?
• •Are the seals in good condition, not compressed flat, torn, or missing?
• •Is the brush or blade element intact and making consistent contact with the opposing surface?

Self-Closing Device

• •Is a self-closing device (door closer) fitted and functioning?
• •Does the closer fully close the door into the frame from any angle of opening? (Test from 5 degrees open — the door must latch shut under the closer's power alone.)
• •Is the closer correctly adjusted — not too fast (hazard) and not too slow (fails to latch)?
• •For doors fitted with hold-open devices, is the hold-open connected to the fire alarm system and does it release the door when the alarm activates?

Hinges

• •Are the hinges of the correct type and number? (Fire doors typically require three hinges of grade 13 or CE marked to BS EN 1935.)
• •Are all hinge screws present and tight?
• •Are the hinges free from distortion, wear, or corrosion?

Latch and Lock

• •Does the door have a functioning latch or lock that holds it in the closed position?
• •For doors on escape routes, is the latch or lock operable without a key from the escape side?
• •Is the latch engagement sufficient to resist the expansion forces that occur during a fire?

Glazing

• •If the door contains glazed panels, is the glazing fire-rated and marked accordingly?
• •Is the glazing undamaged (no cracks, chips, or failed seals)?
• •Is the glazing bead or gasket system intact and secure?
• •Is the glazing consistent with the door's tested configuration?

Signage

• •Is the door provided with appropriate fire door signage? ("Fire door — keep shut" or "Fire door — keep locked" as applicable.)
• •For doors fitted with hold-open devices, is "Automatic fire door — keep clear" signage displayed?
• •Is the signage legible and correctly positioned?

Threshold and Floor Condition

• •Is the floor surface beneath and around the door free from obstructions, floor coverings, or raised thresholds that could prevent the door from closing fully?
• •Are any floor-mounted door stops present? (These must not be used on fire doors, as they prevent closure.)

Inspection Frequency Requirements

There is no single universally mandated inspection frequency for all fire doors. The requirements depend on the building type and the applicable legislation:

• •Higher-risk residential buildings (Building Safety Act 2022) — Flat entrance doors: quarterly. All other fire doors in common areas: annually. These are statutory minimum frequencies.
• •All other premises under the Fire Safety Order — The Order requires that fire doors are "maintained in efficient working order." Best practice guidance from the Fire Door Inspection Scheme (FDIS) and the British Woodworking Federation recommends six-monthly inspections for all fire doors, with quarterly inspections in high-traffic areas.
• •Fire risk assessment driven — The fire risk assessment may specify higher inspection frequencies based on the assessed risk. For example, fire doors in a hospital or care home, where occupant vulnerability is high, should be inspected more frequently than in a low-occupancy office building.

In addition to formal inspections, the responsible person should ensure that basic visual checks — door closes fully, no obvious damage, not propped open — are incorporated into daily or weekly routines.

Responsible Person Duties

The responsible person's duties regarding fire doors extend beyond simply arranging inspections:

• •Ensuring competence — Inspections should be carried out by persons with adequate training and experience. The FDIS qualification is widely recognised, though not legally mandated. At a minimum, inspectors must understand the components of a fire door assembly, the relevant standards, and the criteria for pass/fail assessment.
• •Preventing misuse — Propping fire doors open (with wedges, hooks, or other improvised devices) is one of the most common fire safety violations. The responsible person must establish and enforce a clear policy prohibiting this practice, supported by signage and staff training. Where operational needs require doors to remain open, hold-open devices connected to the fire alarm system must be installed.
• •Managing modifications — Any proposed modification to a fire door (changing locks, adding vision panels, fitting letterboxes) must be assessed against the door's tested configuration. Uncontrolled modifications are a frequent cause of fire door failure.
• •Maintaining records — Comprehensive records of all inspections, deficiencies, and remediation actions must be kept and made available for review by fire risk assessors, enforcement officers, and (for higher-risk buildings) the Building Safety Regulator.

Common Fire Door Failures

Analysis of fire door inspection data consistently reveals the same categories of failure:

• •Excessive gaps — Gaps between the leaf and frame exceeding 4mm, often caused by frame movement, hinge wear, or incorrect hanging. This is the single most common fire door deficiency.
• •Missing or damaged intumescent strips — Strips that have been painted over, removed during maintenance, or damaged by impact. Without intact intumescent strips, the door cannot achieve its rated fire resistance.
• •Non-functioning closers — Closers that have been disconnected, are too weak to fully close the door, or are missing entirely. A fire door that does not close is not a fire door.
• •Propped open — Doors held open by wedges, fire extinguishers, bins, or other objects. This is a behavioural issue as much as a technical one, and requires ongoing management attention.
• •Damaged or missing cold smoke seals — Particularly common on older doors where seals have degraded over time.
• •Incorrect or missing glazing — Standard glass fitted where fire-rated glass is required, or glazed apertures cut into fire doors without appropriate fire-rated framing.
• •Missing certification — No visible label, plug, or other identification confirming the door's fire rating. While the absence of a label does not necessarily mean the door is non-compliant, it makes verification significantly more difficult.

Documentation Requirements

Adequate documentation for fire door management includes:

• •Door schedule — A register of every fire door in the building, recording location (preferably on a floorplan), fire rating, manufacturer, installation date, and unique identifier.
• •Inspection records — For each inspection event: date, inspector name and qualifications, inspection outcome for each checklist item, photographs of deficiencies, and overall pass/fail determination.
• •Remediation records — For each deficiency: description, priority, assigned contractor or in-house team, target completion date, actual completion date, and post-remediation verification.
• •Modification records — Any changes to fire door specifications, including the rationale, test evidence supporting the modification, and sign-off by a competent person.
• •Training records — Evidence that inspectors are appropriately trained and that building occupants have been informed of fire door policies.

Digital Inspection Workflows

Digital inspection workflows transform fire door management from a periodic paper exercise into a continuous, spatially referenced compliance system. The workflow operates as follows:

1. Register population — Every fire door is plotted on the building floorplan with its fire rating, location reference, and unique identifier. This provides a complete, visual register that can be shared with all stakeholders.

1. Inspection scheduling — The system generates inspection tasks based on the defined frequency for each door. Tasks appear on the inspector's mobile device with the door's location shown on the floorplan.

1. On-site inspection — The inspector navigates to each door using the floorplan, completes the structured checklist on the device, and photographs any deficiencies. The checklist enforces completeness — every item must be addressed before the inspection can be submitted.

1. Automatic status update — The door's status on the floorplan updates immediately: green for pass, amber for minor issues, red for significant failures. This provides a real-time compliance view for the responsible person.

1. Remediation workflow — Failed items generate remediation tasks with priority levels. These tasks are assigned to contractors or in-house teams, tracked through to completion, and verified before the door's status is updated.

1. Reporting and audit — The complete inspection history for each door is available at any time, supporting fire risk assessment reviews, regulatory inspections, and insurance surveys.

Plotstuff, as a modern spatial infrastructure software platform, supports this workflow by providing floorplan-based asset placement, structured inspection forms, photographic evidence capture, and immutable audit logging — replacing the fragmented combination of paper checklists, spreadsheets, and email chains that most organisations currently rely on.

Plotstuff enables building managers to maintain a complete, spatially referenced fire door register with automated inspection scheduling and structured remediation workflows — providing the real-time compliance visibility that regulatory enforcement increasingly demands.

Remediation Tracking

Identifying deficiencies is only valuable if those deficiencies are corrected. A robust remediation tracking system must include:

• •Priority classification — Critical (door cannot perform its fire safety function — e.g., closer missing, door cannot close), High (significant degradation — e.g., excessive gaps, damaged intumescent strips), Medium (minor issues that should be addressed within the next inspection cycle), and Low (cosmetic issues with no fire safety impact).

• •Assignment and accountability — Each remediation item must be assigned to a specific person or team with a defined target date. Unassigned items are effectively orphaned and unlikely to be resolved.

• •Progress tracking — The system should provide visibility of all open remediation items, their ageing (time since identification), and their current status (awaiting parts, scheduled, in progress, awaiting verification).

• •Verification — Completed remediation must be verified by a competent person to confirm that the work has been carried out correctly and the door now meets the required standard. Verification should include re-inspection of the specific items that were deficient.

• •Escalation — Items that remain open beyond their target date should trigger automatic escalation to the responsible person and, where appropriate, senior management. Persistent non-compliance with remediation targets is a governance failure that increases both fire risk and regulatory exposure.

The integration of remediation tracking with the fire door register on a floorplan provides spatial context for maintenance planning. A cluster of failed doors in one area may indicate a systemic installation issue, water damage, or heavy traffic wear that warrants a root-cause investigation rather than individual repairs.

Key Takeaways

• •Fire doors are passive fire protection measures that must be maintained as complete assemblies — leaf, frame, seals, closer, glazing, and ironmongery — to perform their rated function.
• •The Regulatory Reform (Fire Safety) Order 2005 and the Building Safety Act 2022 establish the legal obligations for fire door maintenance, with specific statutory inspection frequencies for higher-risk residential buildings.
• •A comprehensive inspection checklist covering gaps, intumescent strips, smoke seals, closers, hinges, glazing, signage, and certification is essential for consistent, defensible inspections.
• •Common failures — excessive gaps, damaged seals, non-functioning closers, and propped-open doors — are consistent across building types and require systematic management to address.
• •Digital inspection workflows anchored to floorplans provide structured data capture, real-time compliance visibility, and immutable audit trails that paper-based systems cannot match.
• •Remediation tracking with priority classification, assignment, verification, and escalation ensures that identified deficiencies are corrected, not merely documented.

Frequently Asked Questions

Can I inspect fire doors myself or do I need a qualified inspector?

For routine visual checks (door closes, not propped open, no obvious damage), building staff can perform these inspections after appropriate training. For formal compliance inspections that will form part of the building's fire safety records, inspectors should be competent — possessing the knowledge and experience to assess all components of a fire door assembly. The FDIS (Fire Door Inspection Scheme) certificate is a recognised industry qualification, though not a legal requirement.

What should I do if a fire door fails its inspection?

The response depends on the severity of the failure. A door that cannot close (missing closer, severe warping, or obstruction) must be addressed immediately — either repaired, replaced, or (as a temporary measure) the area managed with additional fire safety measures such as a fire watch. Less critical issues should be logged, prioritised, and scheduled for remediation within a defined timeframe.

How do I know if my fire door is FD30 or FD60?

Look for a certification label or plug, typically located on the top edge of the door leaf or within the hinge recess. The label should identify the manufacturer, the test standard, and the fire rating. If no label is present, the door should be treated as unrated unless its specification can be confirmed through other documentation (installation records, manufacturer's confirmation).

Are letterboxes permitted in fire doors?

Only if the letterbox has been tested as part of a compatible fire door assembly and is fitted in accordance with the test evidence. A standard letterbox fitted to a fire door without appropriate fire-rated protection (typically an intumescent letterbox kit) will compromise the door's fire resistance.

How does fire door inspection relate to fire compartmentation?

Fire doors are integral components of fire compartmentation. A compartment wall with a failed fire door is a compromised compartment. Inspection results should be considered alongside compartmentation survey data — managed as part of the broader fire safety asset management programme — to provide a complete picture of the building's passive fire protection integrity.

Next Steps

Establish a fire door register for your building portfolio by plotting every fire door on its floorplan with rating, location, and condition data. Implement a structured inspection regime aligned with the frequencies required by legislation and your fire risk assessment. Use digital inspection workflows to enforce checklist completeness, capture photographic evidence, and maintain an immutable audit trail.
