1. Why are fire doors so important?
Fire doors are important because they keep the fire or smoke in the room or ‘partition’ in which it started. They stop it from spreading to other areas of the building. Fire doors are an integral part of the passive fire protection system of any building.
2. What do fire doors do?
Fire doors save lives and prevent further damage to the building and its contents:
They contain the fire in the room in which it started
Fire doors keep escape routes, such as corridors, clean from fire, giving building occupants more time to escape and better access to the fire service.
They protect the rest of the building, its contents and other nearby buildings from further damage.
3. How do fire doors work?
Fire doors prevent the fire from spreading for a certain amount of time. They are made of fire resistant materials for either 30 minutes or 60 minutes, depending on the degree of the fire door. Fire doors are fitted with booster strips in a groove at each end of the door frame or fire door. When a fire breaks out, the heat causes the rising strips to expand to fill the gap between the fire door and the frame. This seals the room and stops the spread of fire for a certain amount of time. A fire door will only work if it closes when a fire breaks out, so you should always make sure your fire door is equipped with an automatic closing door and a sign identifying the door as a fire door.
4. How are fire doors made?
Fire doors are usually thicker than a standard door and most have a strong core of variable material. The construction of fire doors varies depending on the production. But, the critical part is that it is tested and certified to withstand fire for at least 30 minutes. Manufacturers must test the design of their fire doors and frames together as a set at an approved fire door testing center. Then they should be considered for certification. When certification is approved, each fire door set constructed according to the same design specifications by that manufacturer will be affixed with a label. The label identifies the manufacturer, date of manufacture and fire rating. This label can usually be found on the top edge of the door.
5. How long do fire doors last?
Fire doors and their frames are usually tested to hold fire for 30 minutes (FD30) or 60 minutes (FD60). Their ability to withstand fire depends on their proper installation with proper seals and fire rated equipment, including fire door closers. The condition of a fire door, especially a door that is in regular use can deteriorate over time. Check your fire doors regularly and make sure any fire door maintenance is done immediately. Fire door inspections can help identify fire doors that are inconsistent. Fire doors
can have a rating greater than 60 minutes, but these are not required in most situations.
6. Are fire doors important?
Fire doors play an important role in reducing this risk in many buildings. These types of buildings must have a fire risk assessment. Fire risk assessments are an in-depth review of the premises. They will highlight any fire hazards with recommendations to reduce or eliminate these hazards, including where fire doors should be used and what the assessment should be.
