1. Preventing the spread of fire: Fire doors can prevent flames and high temperatures from penetrating within a building for a specific period, thus limiting the spread of fire within the building.
2. Blocking the spread of smoke: Smoke is more deadly than flames in a fire. Fire doors can block the spread of smoke, providing a clear passage for evacuation.
3. Protecting evacuees: In the event of a fire, fire doors can maintain the safety of evacuation routes, ensuring the safe evacuation of people inside the building.
4. Reducing property damage: By preventing the spread of fire and smoke, fire doors can effectively reduce property damage inside the building.
