How to identify a fire door?- ZDoors

Understanding fire doors is essential for building safety. According to a 2017 survey by Ironmongery Direct, nearly 60% of people cannot correctly identify a fire door. This lack of awareness can result in poor inspection and maintenance and put lives at risk. Fire doors are specialised barriers designed to prevent the spread of smoke and fire and give occupants time to evacuate safely. You need to identify fire doors to ensure your building meets all safety standards. To learn how to identify fire doors, read on.

How to Identify a Fire Door

To identify a fire door, you need to consider these factors:

Identify A Fire Door-Zdoors

  1. Certification: The most accurate way to recognise a fire door is through certification. Usually, you can find the certification on the top edge of the door leaf.
  2. Gaps: The spaces surrounding the top and sides should be about the width of a £1 coin, or less than 4 mm thick.
  3. Intumescent Seals: Seek out a narrow band across the length of the frame. These seals resist smoke and flames by expanding when heated.
  4. Hinges: A fire door needs three hinges that are firmly fastened and free of broken or missing screws.
  5. Closing Mechanism: Self-closing mechanisms enable fire doors to securely close into the latch without adhering.
  6. Signage: For ease of identification, fire doors in business environments are frequently marked with required signage.

Internal fire doors are critical components of building protection systems designed to prevent the spread of fire and smoke within a structure.

How to determine fire rating of a door

Again, if you want to recognise the fire rating of a door, you should check its certificate. Check the top of the fire door to find the certificate. It states fire resistance duration. FD30 means it can prevent fire from spreading for 30 minutes and FD60 means it can do it for one hour.

How to Identify a 30-Minute Fire Door (FD30)

The purpose of a 30-minute fire door (fire door FD30) is to offer fire resistance for at least 30 minutes. It can be recognised by:

  • A certification label with the number FD30 on the upper edge of the door.
  • Door frame-mounted intumescent seals.
  • Any gaps surrounding the door that are no larger than 4 mm.
  • A self-closing mechanism that makes sure the door closes fully.
  • Three fire rated hinges that are all securely fastened and in good condition.

How to Identify a 60-Minute Fire Door (FD60)

A 60-minute fire door (fire door FD60) offers at least one hour of fire resistance. With some significant differences, it has the same features as an FD30 door:

  • An FD60-specific certification label.
  • More robust hinges (Grade 13 fire rated hinges) and a long-lasting self-closing mechanism for enhanced protection.
  • Stronger intumescent seals to withstand greater temperatures
  • Thicker construction, frequently with additional fire-resistant components.

What is the difference between a fire door and a normal door?

Regular and fire doors serve different roles. Fire doors are made with strong materials that can withstand the spread of smoke and fire. In contrast to regular doors, they undergo testing and are rated based on how long they can withstand a fire. The function of a fire door remains the same whether it is open or closed. It ensures safety in an emergency by automatically closing to seal gaps and stop fires from spreading.

Unlike ordinary doors, fire doors do not have wedges attached to them. Wedges are used to keep a door open for longer. There are no wedges anywhere near fire doors, as they must close within seconds.

How often should we check our fire doors?

You should check your internal fire doors at least every six months. This ensures your fire door is still meeting safety standards. Fire doors installed in public places and more crowded locations should be checked every month by the responsible person.

Conclusion

Every fire door must have documents proving it satisfies its fire rating. Now that you know how to identify a fire door, make sure it’s properly maintained. Fire doors in high-traffic areas are regularly used, which causes them to deteriorate more quickly. A fire door that cannot fully close will not function properly in an emergency. For this reason, active fire doors should be inspected every three to six months.

FAQ

1) How to identify whether a door is a fire door or not?

Check for a certification label on top of the door, fire-resistant materials, intumescent seals, three or more hinges, and a self-closing mechanism.

Look for the certification label, usually on the top or side of the door, which indicates the fire resistance duration (e.g., FD30 for 30 minutes).
