Fire doors require latching to ensure they are securely closed at all times, preventing the spread of fire and smoke between different areas of a building. This helps to compartmentalize the fire, providing occupants with a safe escape route and allowing firefighters to contain and suppress the fire more effectively.
A famous quote by President Franklin D. Roosevelt perfectly captures the importance of fire doors: “When you come to the end of your rope, tie a knot and hang on.” Similarly, fire doors play a crucial role in “tying a knot” in the event of a fire, providing a barrier that can help save lives and protect property.
Here are some interesting facts about fire doors:
-
Fire doors are designed and constructed to resist the spread of fire and smoke for a specified period of time, typically 20, 45, 60, or 90 minutes.
-
Fire doors are required by building codes and regulations in order to enhance the safety of occupants and to comply with fire safety standards.
-
Fire doors are usually made of materials that are fire-resistant, such as steel, gypsum, or solid timber. They are built to withstand high temperatures and remain intact during a fire.
-
Fire doors are equipped with intumescent strips or seals that expand when exposed to heat, filling gaps and creating a tight seal to prevent the passage of smoke and flames.
-
Fire doors are subject to regular inspections and maintenance to ensure their proper functioning. This includes checking the condition of the latching mechanism and ensuring that the door closes fully and latches securely.
Here’s a table summarizing the benefits of latching fire doors:
| Benefits of Latching Fire Doors |
|---|
| Prevents the spread of fire and smoke |
| Compartmentalizes the fire |
| Provides occupants with a safe escape route |
| Enables firefighters to contain and suppress the fire effectively |
In conclusion, fire doors require latching to fulfill their crucial role in containing and controlling the spread of fire. By securely closing and forming a barrier, fire doors help to safeguard lives and property during emergencies. As President Roosevelt’s quote suggests, fire doors serve as the “knot” that holds everything together and offers hope and protection in times of crisis.

When a fire door closes, it must latch to prevent it from being forced open by the pressure from a fire. NFPA 80 requires fire doors to have an active latchbolt that can not be held retracted, except in the case of electrified hardware incorporating a mechanism that automatically latches the door if a fire occurs.
Fire doors require latching to keep the door closed under the pressure created by a fire. This prevents the fire’s pressure from pushing the door open, negating its fire protection. Hardware on fire door assemblies has to have an active latchbolt to prevent the pressure caused by a fire from pushing the door open and allowing smoke and flames to spread. Fire doors must be kept closed and latched or arranged to provide automatic closing during the time of a fire.
Each fire door must be equipped with a positive latch to keep the door closed under the pressure created by a fire. (This keeps the fire’s pressure from pushing the door open, negating its fire protection.)

Fire doors must be kept closed and latched or arranged to provide automatic closing during the time of a fire. In addition, blocking or wedging of doors in the open position is prohibited, as it violates the required operation and closing feature of the door.

Subsequently, Does a fire door have to have a latch?
Response will be: Locks and latches
A fire door must remain closed within the frame and therefore a latch or lock will ensure this happens.
In this way, What is a fire door latch? Fire Door Latches
These latches can withstand flames for between 30 and 90 minutes, and make great additions to kitchen doors. Perfect for use alongside fire rated hinges and locks, each fire rated door latch has been crafted to look good and give you peace of mind too.
Also question is, Do fire rated doors have to be automatic or self closing and latching?
Answer will be: In summary, fire-rated doors must be able to close in the event of a fire, and today, there are several types of closing mechanisms that can do so while adhering to fire-safety requirements. One of the most common means to provide an effective fire-rated door is by specifying a self-closing fire door.
What does positive latching mean?
A positive latch is a latch that catches automatically when the door is closed. For example, a typical lockset is a positive latch, while a deadbolt is not. Each fire door must be equipped with a positive latch to keep the door closed under the pressure created by a fire.
Does a fire door need a latch?
Answer to this: The latch prevents the fire door from distorting in the initial stages of the fire. If you require a fire door without a latch then you would need a pivot hinge and the test details that come with the door should indicate this is possibility. 5 months later…
Just so, Are fire doors self-latching? All fire doors have an additional safety feature – they must be self-closing and self-latching. This means that in the event of a fire, all of these doors will close and latch without a person’s help. This is accomplished through the use of a closer or spring hinge and a fire-rated lockset or exit device.
Also Know, Can panic door hardware be used on a fire door?
In reply to that: Fire Exit Hardware – When panic hardware is used on fire door assemblies, it must be fire exit hardware, which is listed for both panic (UL 305) and fire (UL 10C / NFPA 252). This hardware can not incorporate the mechanical dogging feature, which would allow the latch to be held back and could leave the door unlatched during a fire.
Just so, Can a door latch egress if a temperature is too high?
Because the pin only projects when a high temperature is reached, it does not present an egress problem and this type of hardware is allowed by the model codes. Electric Latch Retraction – NFPA 80 allows latching devices which do not latch in the normal mode, as long as the door automatically becomes positively latched in a fire emergency .
