HARDWARE& SECURITY A Vital key to fire safety »»Fire doors are a vital part of a building’s fire safety and ultimately can save lives. However, it is just as important to think about the additional hardware components that are required to ensure the door is fit for use and will enable it to function correctly in the event of a fire. Martin Smith, product manager at IronmongeryDirect, explains the importance of locks and additional hardware that need to be considered to ensure the door operates effectively in the event of a fire. Fabricators and installers have an important role to play in the supply, correct installation and ongoing maintenance of fire doors and their accompanying hardware to ensure they are fit for purpose, meet the required standards and most importantly provide protection to the occupants of the building. First and foremost, it’s important to keep up-to-date with the latest fire safety legislation and standards to be able to recognise when fire doors and hardware don’t meet the required standards and provide guidance. In addition, by understanding what is expected, installers and fabricators can recommend and install the right hardware and ensure the fire door complies with regulations. Failure to fit and maintain fire doors and accompanying hardware correctly could put lives at risk and lead to potential legal implications. Hinges, locks and latches Hinges, locks and latches are all equally important when considering the different hardware components that make up a fire door. If these are not regularly maintained or replaced when broken the risk of the fire door not doing its job correctly during a fire is extremely high. you have to help it along then it’s not working properly and this needs to be put right. Another factor to bear in mind is that most door closers are graded with a power size. This needs to be a minimum of size 3 for a fire door; any lower than this and it is not considered suitable and needs to be changed immediately. As closers for fire doors have a critical safety function, they must be able to overcome any resistance from locks, latches or sealing systems that are present on the door. They should also be CE marked to BS EN 1154 including annex A. When it comes to hinges, fire doors need at least three to operate correctly. These should be fitted with the correct amount of screws at the right size and marked with a CE stamp. They should be routinely checked for wear and tear an d should be treated if they are showing any signs of rust or corrosion. It’s also important to install a high quality lock as they help to ensure a door remains closed within its frame. A good example of a quality lock is the Altro Euro Profile Sashlock which boasts a 60 minute fire rating, meaning it will withstand the effects of a fire for up to an hour. In order for the locks to be compliant with the fire regulations, they must be fitted with a suitable intumescent lock kit. Once the intumescent strips are attached they help to provide vital fire protection for the critical weak points of the lock. 72 » OCT 2015 » CL EARVI E W- UK . C O M When choosing a latch it’s important to go for strong, quality brands as they need to hold the door firmly in place without rattling. They also need to have the correct intumescent sleeve fitted to it to retain the doors integrity. Both locks and latches should be CE marked and further product certification by a third party is recommended. Door closers Another important feature to consider when ensuring a fire door is fit for purpose is its door closer. Automatic closing devices operate to ensure that doors close properly to prevent the spread of fire. They should be fitted to all fire doors and be capable of closing the door from any angle of opening. This can be tested by opening the door to five degrees and making sure it closes and engages with the latch. Fire door closers need to work unaided – if Hold open devices Hold open devices such as the Dorgard Fire Door Holder are a great way of legally holding open fire doors in high traffic areas such as corridors instead of using a wedge or other device, which is against fire regulations. These devices, used together with a door closer, will activate after hearing a fire alarm allowing the door to close automatically. These devices need to be maintained and tested on a regular basis. The unit must be located in the vicinity of the active alarm or bell in order to operate correctly. As fire doors are a fundamental part of fire protection it’s essential to consider every detail when installing, maintaining and checking them in order that they provide the maximum protection against the spread of fires. All components need to be checked on a regular basis and repaired or replaced if they are found to be damaged or broken.
