Where are fire doors usually installed?

Fire doors are usually installed in the following locations:

1. Building entrances and exits: Fire doors are usually installed in the main entrances and exits of buildings, such as lobby, front hall or foyer. This can ensure that people can quickly escape from the building in an emergency and prevent the fire from spreading to other areas.

2. Stairs: Stairs are one of the fastest fire spreading areas in buildings. Therefore, setting fire doors in the stairwell of each floor can effectively isolate the fire source and prevent the fire from spreading to other floors.

3. Elevator room: The elevator room is also a high-risk area in the building, because there may be wires and equipment in the elevator shaft. Once a fire breaks out, it is easy to expand. Installing fire doors can prevent the fire from spreading to elevator shafts and other floors.

4. Fire escape: The fire escape in the building is an important passage for firefighters to enter the fire site and evacuate trapped people. Fire doors can ensure that the passage is not affected by fire and ensure the smooth progress of fire rescue work.

5. Isolated area: In some areas with special safety requirements, such as chemical laboratories and warehouses storing dangerous goods, it is also necessary to install fire doors. These areas usually have the risk of fire and explosion, and fire doors can isolate these areas and reduce the impact of fire on the surrounding environment.

In short, the installation position of fire doors should be rationally planned according to the specific conditions of buildings and fire danger areas to ensure the safety of people's lives and property.
