FIRE SAFETY
7 things to remember when specifying fire door hardware
» THE UK GOVERNMENT HAS recently commissioned an investigation to review building regulations and fire safety , where it has become increasingly clear that there is a lack of understanding among some contractors , installers and fitters about the role of fire door sets and the implications of modifying hardware specifications .
Here are some top tips from the HOPPE ( UK ) technical team on the key things to consider when specifying architectural ironmongery for fire doors :
1 . Install the correct hardware for your fire door
Fire doors are designed to compartmentalise a building to help protect it and to save lives in the event of a fire .
To do this a fire door must be installed correctly so that it fully closes into its frame , helping to restrict the spread of fire and toxic smoke for a set period of time . A correctly installed fire door gives building occupants time to evacuate safely .
The key components of a fire door and a fire door on an escape route are shown in the diagrams .
2 . Fit hardware in line with manufacturer ’ s instructions
It is essential that the chosen hardware has been tested by the door manufacturer on the specific type of fire door that it is being installed on , as incorrect specification will impact its performance . The door manufacturer ’ s test evidence will advise on the hardware that has been tested with , and is therefore applicable to , the fire door being specified .
There are three types of “ operational ” hardware that are critically important for fire doors to perform : hinges , door closing devices , and locks and latches .
In the event of a fire , these products combine to close and secure the door in its frame for a period of time to allow intumescent protection contained
within the door , frame and around the hardware to expand and fill gaps around the door . Therefore , it is critical the hardware is fitted in accordance with the manufacturer ’ s fitting instructions . Incorrect fitting of these products will affect the integrity and ultimately the performance of the fire door .
3 . Consider the accessibility requirements of building users
As well as meeting fire regulations , also consider the functionality of the door set and fitted hardware . Many fire doors are very heavy , and this can cause accessibility difficulties for some building users .
Safety is paramount so when it comes to replacing any component of the door set or hardware , the products must firstly have been tested as a combination by the door manufacturer and the fire / mechanical performance must be equal to or better than that of the door . Replace ‘ like with like ’ by using the same hardware brand or crosscheck the tested elements and certified products for the door set .
Always consult with the original door manufacturer if in any doubt or contact one of HOPPE ( UK )’ s Guild of Architectural Ironmongers ( GAI ) qualified experts for advice .
