Remember, you must maintain doors correctly and can be prosecuted under the Regulatory Reform (Fire Safety) Order if you fail to do so.
Fire Door Inspection
As with any other life-saving product, a fire door should be checked regularly to ensure it functions correctly and is ready to use. It should be considered in exactly the same way as testing a smoke alarm or a fire extinguisher.
Any slight alteration to the door or its surroundings can affect the performance of a door. Periodic checks should be carried out at least every 6 months, or more regularly depending on the traffic using the door.
