How to design the fire elevator front room?

Fire protection design requirements for fire elevator lobby.

The fire elevator must be equipped with a front room to prevent smoke and facilitate the work of firefighters. The fire protection design of the front room shall consider the following aspects:

1. Front chamber position

The front room should be located near the outer wall, so that the windows on the outer wall can be used for natural smoke exhaust, which can not only meet the needs of fire protection, but also save investment. The layout requirements are generally consistent with the location of the fire elevator, so that the firefighters can quickly reach the fire elevator entrance and start rescue work.

2. Anterior chamber area

The area of the front room should be determined by the nature of the building. The residential building should not be less than 4.5 square meters, and the public building and industrial building should not be less than 6 square meters. When the fire elevator and smoke proof stair share a front room, there are many people crossing or staying in the front room, so the area should be increased. The residential building should not be less than 6 square meters, the public building should not be less than 10 square meters, and the short side length of the front room should not be less than 2.5 meters.

3. Smoke prevention and exhaust

The front room shall be equipped with mechanical smoke exhaust or natural smoke exhaust facilities. In case of fire, a large amount of smoke can be discharged near the front room to ensure that firefighters can successfully fight the fire and rescue personnel.

4. Indoor fire hydrant

Fire riser and fire hydrant shall be set in the front room of fire elevator. The fire elevator is the main attack route for firefighters to enter the fire part of the building. In order to open the passage and launch attacks, the front room should be equipped with fire hydrants. It is worth noting that a small movable door should be set under the fire door to facilitate the water supply belt to pass through the fire door without causing fireworks to enter the interior of the front room.

5. Front room door

The doors of the front room and walkway of the fire elevator shall at least adopt Class B fire doors or fire rolling shutters with stagnation function to form an independent and safe area, but the doors of the shared front room cannot adopt fire rolling shutters.

6. Water retaining facilities

Water retaining facilities should be set at the front door of the fire elevator to prevent water from entering the elevator from there.
