Installations, Remediations & Inspections

There are two generic types of fire door:

  • ire- resisting doors; normally an internal door or shutter, which together with its frame and hardware, allows for the movement of people and everything else within a fire compartment wall. When closed, the intention is to restrict fire and smoke to a predictable level of performance.
  • Non- fire rated exterior emergency escape doors or shutters, also known as fire escape doors. They are normally not ‘fire resisting’ in that exterior fire exit doors are not tested or expected to provide fire integrity or fire resistance. Their main purpose is to open immediately and easily in the direction of escape (outwards) for persons to reach an external place of safety.

Most of the time, a fire door is like any other door, but if a fire breaks out it performs vital and specific tasks. In the extreme it may act as a barrier, holding back the spread of fire. More commonly it will contain or limit the cold smoke a fire will generate, enabling people to safely evacuate an area or an entire building. In extreme circumstances this will allow the fire services to enter a burning building in relative safety.

All fire doors must have evidence of performance to ensure that fire door compliance is to the required standard for their location and use.

The level of fire door inspection that is suitable and sufficient to meet legal requirements can be complex and is dependent on a number of factors including the size and type of building and its occupancy.

It is generally agreed that for a new or upgraded door set, the level of inspection should be to a very high standard, ensuring that the door has been installed or remediated in keeping with how it was fire tested in order to replicate performance or meet the standard of remediation intended and required. In a new door installation, evidence of performance, i.e. comparing test evidence and manufacturer’s installation details and specification with what and how it has been installed, is key to determining (assessing) actual fire performance.

Fire doors in occupied buildings also have to be inspected at regular intervals to ensure they are being adequately managed and maintained, but expert guidance may be required regarding frequency and detail of inspection and by whom in order for this to be suitable and sufficient. There are a number of factors that will help determine this, not least the usage and importance of the doors in terms of overall fire containment.

Fire exit doors are often low usage but it must be recognized that their efficient function is critical to the safe evacuation from a building. As such they should be inspected regularly, a minimum of every 6 months, even though they are often linked to an alarm system so that special arrangements may have to be made to do so.

For routine inspection and maintenance, BS9999 2017 provides specific guidance, but it should be understood that doors inspected to that standard need to have been installed correctly and previously maintained sufficiently for the basic checks given in this standard to be adequate.
Bearing in mind that the majority of fire doors in existence are currently uncertified with no known ‘paper trail’ there is commonly a requirement to inspect / assess doors with no available information other than the door set itself. Limited client input and the need to be pragmatic, often requires an expert view to be taken on the extent such doors are fit for purpose.

As with condition surveys, the scope and detail of fire door inspection is crucial and exactly what is be checked should be agreed between all stakeholders in writing before the inspections take place.

Due to the mandatory need for “a suitable system” potentially liable to scrutiny by others seeking evidence that a robust inspection regime is or was in place, inspections need to be recorded and this is done by Golden Thread Fire electronically, using an agreed pass / fail criteria whereby the vital elements of each door are captured upon first inspection using bespoke Bolster software on a hand held device and is then issued as both a door schedule and a report to record and highlight remediation and replacement issues before being stored and updated during further ongoing inspections.
