What is the primary function of fire barriers in a building?

The primary function of fire barriers in a building is to prevent the spread of fire and smoke. Fire barriers are constructed walls, floors, or other elements designed to compartmentalize a building and contain a fire within a specific area, thereby protecting occupants and other sections of the structure from fire and smoke damage. This containment helps to provide additional time for evacuation and reduces the potential for property loss and structural damage.

While other aspects such as aesthetic design, natural lighting, and structural integrity may be important considerations in building design, they do not define the main purpose of fire barriers, which is fundamentally about fire safety and hazard mitigation. By effectively maintaining the integrity of these barriers, the building can enhance overall safety for its occupants and limit the possibility of widespread damage in the event of a fire.
