What is the purpose of a "fire curtain" in a building?

The purpose of a "fire curtain" in a building is to contain fire and smoke within a specific area. Fire curtains are specially designed barrier systems that help to prevent the spread of fire and smoke to other parts of the building, thereby enhancing safety for occupants and providing firefighters with more time to respond effectively. By containing a fire to a limited area, these curtains can help protect escape routes and allow for more controlled firefighting efforts.

In contrast, while ventilation for smoke may be necessary during a fire, that is not the primary function of a fire curtain. The aesthetic appeal of a fire curtain is not relevant to its safety function, and while ease of passage during evacuations is important, the curtain itself is not intended to facilitate movement; its main goal is to act as a barrier to protect life and property.
