What is the function of fire door systems?

Fire door systems are primarily designed to slow down the spread of fire and smoke within buildings. They function as a barrier, containing a fire to the area where it started and significantly delaying its movement to other parts of the structure. This containment is crucial for ensuring the safety of occupants by allowing them more time to evacuate safely and reducing the likelihood of fire spreading quickly through different areas.

In addition to their primary function of containment, fire doors are constructed from materials that can withstand high temperatures and are fitted with self-closing mechanisms to ensure they remain closed during a fire. This not only helps protect exits and escape routes but also minimizes damage and helps maintain the integrity of the building's overall safety design.

While easy access for maintenance, aesthetic appeal, and increased occupancy may be factors considered in building design, they do not pertain to the primary purpose of fire door systems, which is focused exclusively on fire safety and prevention.
