Fire doors are crucial components in safeguarding against the spread of fire and smoke in both commercial and residential buildings.
Constructed to withstand fire for specified durations, they allow occupants vital time to evacuate safely. However, their effectiveness hinges on proper installation and regular maintenance. This piece delves into the necessity of fire door upkeep, the importance of regular inspections, and how to identify potential issues with fire doors.
Importance of Fire Door Maintenance
Fire doors, like any part of a structure, experience wear and tear over time, leading to deterioration in seals, hinges, frames, and glazing. This deterioration can compromise their fire containment ability.
Regular maintenance and inspections are crucial to identifying these problems early and mitigating risks to occupants. Additionally, maintaining fire doors isn't just a safety issue; it is a legal obligation. Building owners and managers are required by law to ensure regular checks and maintenance of fire doors, with non-compliance risking fines, legal repercussions, and, more importantly, endangering lives.
Common Faults in Fire Doors
The Fire Door Inspection Scheme (FDIS) highlights that 75% of fire doors fail to meet standards due to neglect, incorrect specifications, and misunderstandings of their importance.
Notably, 61% of surveyed doors had missing or poorly fitted seals, making them ineffective at filling perimeter gaps essential for containing smoke and fire. These seals are designed to expand when heated, blocking gaps around the door frame during a fire.
Excessive Gaps and Proper Signage
Fire doors should not have gaps wider than 3mm between the door and the frame
Fire doors should not have gaps wider than 3mm between the door and the frame, which can be checked using a £1 coin for reference.
The bottom threshold gap can range from 8-10mm. Proper and clear signage is also a critical, albeit often overlooked, aspect of fire door safety. Identifying fire doors readily can prevent people from leaving doors open or blocking them, a common issue as discovered by FDIS where over one-third of inspected doors had inadequate signage.
Damaged Doors and Their Impact
Damage to fire doors drastically reduces their protection capabilities. Every component, including handles, locks, and door structure, requires thorough inspection during maintenance.
Fire doors on escape routes must open in the direction of travel without needing a key. Proper installation includes a standard-height door having at least three hinges with intumescent pads to prevent warping and ensure even weight distribution. For doors over 2.2 meters, four hinges are necessary, and all hinges must have their screws intact to maintain door strength under fire conditions.
Ensuring Fire Door Compliance
To uphold their designated fire-rating, fire doors often need maintenance to accommodate changes in building use, modifications, or general wear and tear.
Regular inspections ensure that doors continue serving their purpose effectively, offering the necessary fire resistance of 30, 60, or 120 minutes as rated. Such diligence is critical in maintaining building safety standards and protecting lives.
Fire doors play a critical role in preventing the spread of fire and smoke within commercial and residential buildings.
They are specifically designed and constructed to resist fire for a specific period, providing valuable time for people to evacuate the building safely. However, fire doors are only effective if they are installed correctly and maintained regularly.
This article is going to explore the importance of fire door maintenance, why regular inspections are vital for fire door safety, and how to spot potential faults with the fire doors.
Importance of fire door maintenance
Regular maintenance and inspections can identify and address these issues
Like any other part of a building, fire doors are subject to wear and tear, and over time, the seals, hinges, frames, and glazing of a fire door can degrade, compromising its ability to perform in a fire.
Regular maintenance and inspections can identify and address these issues before they become a significant risk to building occupants.
Fire door maintenance is also a legal requirement, and building owners and managers have a legal responsibility to ensure that fire doors are maintained and inspected regularly. Failure to do so can result in fines, legal action, and, most importantly, put building occupants at risk.
Faults with fire doors
These seals expand when exposed to heat during a fire, blocking any gaps around the door frame
The Fire Door Inspection Scheme (FDIS) has revealed that between neglect, misspecification, and a misunderstanding of their significance, 75% of fire doors fail to meet the required standard.
Over 61% of the doors surveyed by FDIS were found to have missing or incorrectly fitted seals that failed to fill the perimeter gaps adequately, making this one of the most common faults with fire doors.
These seals expand when exposed to heat during a fire, blocking any gaps around the door frame and preventing the spread of smoke and fire into other areas or rooms.
Excessive gaps
If users can see excessive gaps between the side of the door and the frame, a fire door may be ineffective.
There should never be a gap wider than 3mm at any point between the door and its frame and if users are unsure, they can actually test this with a £1 coin. The threshold gap (bottom of the door) of up to 8-10mm can be acceptable.
Incorrect or unclear signage
While it may seem like a small detail in fire door safety, accurate and clear signage is crucial
While it may seem like a small detail in fire door safety, accurate and clear signage is crucial.
In case of a fire, it’s essential for people to be able to identify which doors are fire doors, their location, and how to access them.
Without proper signage, individuals may leave the doors open or block them unknowingly, endangering others’ safety. Shockingly, over one-third of the doors inspected by the Fire Door Inspection Scheme (FDIS) had inadequate or incorrect signage.
Damaged doors
Damaged doors do not provide the same level of protection as those in perfect working order
Damaged doors do not provide the same level of protection as those in perfect working order. Every aspect of the door, such as the handle, lock, and structure of the door, should be checked within the door survey.
Additionally, if the fire door in question is on an escape route, it must open in the direction of travel, without the use of a key. To ensure proper installation, a standard-height fire door should have a minimum of three hinges, each fitted with intumescent pads.
For doors over 2.2 meters in height, four hinges are required. This helps to prevent warping during a fire by distributing the door’s weight evenly. Additionally, missing screws can compromise the strength of the door under the intense heat generated by a fire so should always be checked.
Fire door maintenance
With that in mind, fire door maintenance is required to ensure that all doors continue to meet the required fire rating. Fire doors are typically rated to resist fire for a specific time, usually 30, 60, or 120 minutes.
However, factors such as changes in the building’s use, modifications to the door or its surroundings, and wear and tear can all affect a fire door’s ability to meet its fire rating. Regular fire door inspections and maintenance can help ensure that the door continues to perform as intended and provide the necessary protection in a fire.
