How fire doors can save lives
Fire doors have proven to be invaluable when it comes to protecting buildings, belongings and people. The safety features built into these specially-designed doors can be the difference between a singed room and serious injury, or even fatalities.
There are many important elements to fire doors and all need to be fully-functioning in order to provide the best protection. Ordinarily, they feature overhead door closers to ensure that they shut automatically, with intumescent and smoke seals around the frame to stop the spread of flames and contain harmful fumes that could otherwise suffocate people. The intumescent seals are designed to expand to several times their original size when exposed to heat, sealing the gap between the door and frame.
When the doors feature glazed apertures, the glass is specially manufactured to resist the sudden temperature changes and high temperatures of a fire – normal glass would quickly break or shatter when exposed to heat.
The ironmongery fitted to a fire door is as important as the door itself. Latches, locks, door closers and other items all need to be certified and compatible with the door itself, otherwise they could fail in the event of a fire.
For fire doors in public buildings, push bars or pads provide a quick exit when fires break out. Fire doors are designed to offer protection but people also need to be able to escape easily from the room that the fire is in, making sure that the door is sealed once again to slow or stop the spread of flames.
 Why certain buildings need fire doors
In the majority of commercial buildings and accommodation premises (this includes blocks of flats, sheltered accommodation, houses of multiple occupancy, etc), fire doors are a legal requirement for the safety and protection of those within. When kept shut in a fire they provide proven protection to both people and property.
 Importance of maintenance
While having a fire door in place can make all the difference, there is little point if it is not looked after and maintained. Like most things, a door's performance over time can deteriorate due to general wear and tear. To keep a fire door in optimum condition, it should be checked biannually. If a problem is noticed with the way the door closes, gaps forming, or any general damage, it should be repaired as soon as the problem arises.
It is also vital that fire doors are properly fitted in the first place to ensure that they function as designed. Skilled, experienced joiners who are aware of, and abide by, the installation guidelines of each doorset are the best bet. Ideally they would have third-party certification for installing fire doors.
The protection fire doors offer during a crisis is unparalleled. They save lives, even if it is only by giving individuals more time to escape. They are essential in public buildings, to lower risk factors and to keep people safe.
