Production Description
According to fire protection requirements for hospital refuge, high-rise ward buildings in hospitals should be equipped with refuge rooms on floor 2 and above. There should be no more than 2 nursing units for the refuge service, and the net area should be determined by no less than 25 square meters per nursing unit. When the refuge room is used for other purposes, it should ensure that the refuge safety and the net area available for refuge are unchanged; it should be close to the stairwell and be separated from other parts by a fireproof partition with a fire limit of no less than 2.00h and Class A fire door.
In the current National Code of Practice for Fire Protection of High-Rise Civil Buildings, it is required that “a public building with a building height of more than 100m should be provided with a refuge floor (room)”.
The refuge or refuge floor is a safe place once there is fire in high-rise buildings, and the fire door in the refuge room is especially important to ensure that the refuge room can function normally when the building is on fire. As a leader in this field, Zhongwo Fire Door has cooperated with many buildings to take the first step to build a safe haven for high-rise buildings.
