4 Fire door checks to prevent the spread of smoke

September 5, 2023 5:08 pm Published by

The fire safety strategy for any facility must include fire-rated doors. They are designed to prevent the spread of fire and smoke, providing occupants with a safe escape route and allowing emergency services to enter the building. However, fire-rated doors can only perform their intended function if they are properly maintained and checked regularly. In this article, we will discuss four fire door checks that can help prevent the spread of smoke in the event of a fire.

  • Check the gaps around the door

Verifying that there are no gaps around the edges is one of the most important inspections to carry out on a fire door. These openings could permit smoke to enter space, making it harder for people to leave and raising the danger of inhalation. Closing the door and looking to see whether there is any light coming through the edges is an easy technique to check for gaps. If the light is visible, there is a hole that needs to be filled.

  • Check the door’s seal.

Another crucial part of a fire door is the seal around the door. By forming an airtight seal around the door’s edges, it aids in stopping the spread of smoke. The seal may weaken with time, allowing smoke to enter space. Close the door and run your hand around the edges, feeling for any gaps or cracks, to test the seal. If you find any, the seal must be changed.

  • Check the hinges.

The hinges on a fire door are responsible for holding the door in place during a fire. If the hinges are loose or damaged, the door may not be able to stay closed, allowing smoke to spread throughout the building. To check the hinges, open the door and ensure that it opens and closes smoothly without any sticking. If you notice any resistance, the hinges may need to be adjusted or replaced.

  • Check the self-closing mechanism.

A self-closing mechanism is a feature of fire doors that helps to keep the door shut during a fire. To stop the spread of smoke and fire, this process is crucial. Open the door and make sure the latch is tightly fastened and that the door closes completely to test the self-closing mechanism. The door’s self-closing mechanism may need to be modified or replaced if it does not latch or close properly.


Regular checks and maintenance of fire doors are critical to prevent the spread of smoke during a fire. The four checks outlined above are a good starting point for ensuring that your fire doors are functioning correctly. Remember to perform these checks regularly, and if you notice any issues, address them promptly to ensure that your building’s fire safety plan is effective. Apart from considering these simple steps, ensure to source only quality products from trusted suppliers like Bin Dasmal Doors who is well known for delivering top-notch fire-rated doors in Dubai!
