The role of a fire door in fire protection is primarily to limit the spread of fire and smoke between different compartments within a building. Fire doors are specifically designed to withstand high temperatures and to maintain their structural integrity during a fire event for a specified period, often rated by time (e.g., 30 minutes, 60 minutes). This containment feature is crucial in protecting occupants, allowing for safe evacuation, and minimizing property damage by preventing flames and smoke from moving to unaffected areas.

The effectiveness of fire doors is enhanced by their installation within walls that also possess fire-resistive qualities, thereby creating a barrier against the passage of smoke and flames. Properly maintained and functional fire doors contribute significantly to a building's overall fire protection strategy.

While aesthetic appeal, noise limitation, and providing emergency exits can be secondary considerations or functions associated with various types of doors, these do not align with the primary purpose of a fire door in the context of fire safety. The essential objective is to establish fire-resistant compartments to protect lives and property during fire incidents.
