The fire doors are essential to any building’s passive fire protection system. They compartmentalize a building to avoid a fire, smoke, or harmful gases from spreading into the protected area, most commonly the exit routes of the building to encourage safe evacuation during a fire. Nonetheless, for them to work correctly, they need careful design. Consider the above techniques.
Each fire door comes with a permanent label, the details of which should remain accessible throughout the door life. Fire-rated door frames may also have some marking or other relief indicating the manufacturer’s details. Frames should typically have a longer duration of fire-resistance than the door.
To determine the fire resistance your building needs, you can consult the building code for your region or talk to the local council about the exact specifications. Fire door manufacturers know about those specifics as well.
Consider Installing Doors That Raise the Temperature
The aim of manufacturing temperature rise fire doors is to reduce heat transfer from one side of the door to another. In the event of a fire, and assuming that the door opens into the stairwell, building occupants may avoid injury if they accidentally touch that door. For these doors, there are different temperatures as well as the duration of temperature rises. However, if you have an automated sprinkler system in the house, you do not need to mount these doors.
Consider Opening and Closing
There are also numerous mechanisms for opening and closing of the fire doors. The idea is to close those doors to prevent the fire from spreading on either side, but they should be easy to open in case of any emergency. The most famous fire door locking systems involve electromagnetic holders and combination locks equipped with smoke detection capabilities.
The standard practice is to have fire doors that are self-closing and under no circumstances will remain open. To facilitate manual operation, if you install doors with automatic engineers that hold them open during regular use, safety regulations dictate that they are disconnected during a fire.
The tools should also be equipped with an active latch bolt, which prevents the door from opening due to pressure on one side. Some doors will have to have a special latch-throw mounted while others will fit well with the normal spring-latch. Fail-safe electrical strikes should also not be used, as they may cause the door to come unlatched; only fault-safe strikes should be used to hold the lock locked in the strike keeper in the event of power failure.
One thing to bear in mind is if you mount the fire door anywhere that exits to a hallway, you could opt for one with a low fire-rate. When the door joins two different buildings, though, the fire door would have to be able to endure the extreme heat it can handle.
While you are at it, getting in touch with a fire door manufacturer that provides a full system would be smart. In addition to providing you with the fire doors, they will ensure that you also get fire extinguishers and an alarm system to ensure that all other safety measures are in effect.
