Fire doors are required as a critical safety feature in buildings to prevent the spread of fire and smoke. These doors are designed to withstand fire for a specific period, allowing occupants to safely evacuate and providing time for firefighters to control the blaze.

Fire doors are required in buildings for several important reasons:
Fire prevention and containment: Fire doors are specifically designed to prevent the spread of fire and smoke within a building. They act as a barrier, confining the fire to a particular area and preventing it from spreading rapidly to other parts of the building. This containment feature is crucial for ensuring the safety of occupants and gives them more time to evacuate.
Protection of escape routes: Fire doors are strategically placed along escape routes, such as corridors and stairwells, to create safe pathways for individuals to exit the building during an emergency. These doors help maintain clear evacuation routes by limiting the intrusion of flames and smoke into these areas. By doing so, they enable a smoother and faster evacuation process.
Increased safety for occupants: Fire doors provide a layer of protection for people inside a building, giving them a vital means of retreat in the event of a fire. They are designed to resist the high temperatures and intense heat generated by fires, offering a safe refuge until help arrives. Fire doors also aid in reducing the risk of injuries by preventing the spread of flames, smoke, and toxic gases that can be harmful or fatal.
Assistance to firefighters: Fire doors play a crucial role in aiding firefighting efforts. By compartmentalizing the fire, they help contain it to a limited area, allowing firefighters to focus their resources and efforts on controlling and extinguishing the blaze. This containment effectively slows down the spread of fire, granting firefighters more time to carry out their operations safely and efficiently.
In the words of Benjamin Franklin, “An ounce of prevention is worth a pound of cure.” This quote emphasizes the importance of fire prevention measures such as fire doors. By investing in proper fire safety measures, including the installation and maintenance of fire doors, potential disasters can be averted or mitigated.
Interesting facts about fire doors:
- Fire doors are typically made of fire-resistant materials such as steel, timber, or glass reinforced with fire-resistant glazing.
- They undergo stringent testing and certification processes to ensure their effectiveness and compliance with safety standards.
- Fire doors are equipped with specialized components, such as intumescent strips or smoke seals, that expand with heat to form a tight seal, preventing the passage of fire and smoke.
- Some fire doors have a self-closing mechanism to ensure they automatically close when not in use, providing continuous fire protection.
- The time for which fire doors can withstand fire varies depending on their rating, with common ratings being 30 minutes, 60 minutes, or 90 minutes.
- Fire doors are an essential part of building regulations and are mandatory in various types of buildings, including commercial, residential, and public structures.
- Regular inspections, maintenance, and proper use of fire doors are crucial to ensure their effectiveness and reliability throughout their lifespan.

Video answer to “Why are fire doors required?”
This video explains the concepts of neutral pressure and positive pressure in relation to fire doors. Fire doors undergo testing to ensure they can withstand high temperatures and prevent the spread of fire. The neutral pressure test assumes there is no pressure buildup in the room, while the positive pressure test simulates pressure building up in the area with the fire. Fire doors must also pass a hose stream test to ensure their integrity. It is essential to consult local building codes to select the appropriate fire door rating and options. Reeb provides both neutral and positive pressure rated doors.

Today, fire-rated doors are usually a requirement for most buildings in order to adhere to the International Building Code (IBC) mandates. A fire-rated door is typically located around stairwells and elevator shafts to help prevent smoke and fire from traveling throughout multiple floors of a building.
Fire doors serve a number of purposes, such as protecting escape routes on stairs and corridors, slowing the spread of a fire, separation fire hazards and providing places of relative safety.
The main functions of fire doors are:
- To allow egress from a space and to close once released
- Protect escape routes from the effects of fire (smoke, gases and flames)
Fire doors are therefore required if they lead to corridors or staircases, for example. They’re also needed to compartmentalise a fire, i.e. to stop it spreading from one part of the building to another. This means they’re used in high-risk areas such as kitchens, storage areas with combustible materials and boiler rooms.
