Wooden Interior Fire Doors
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)”.
Maybe little people concern the refuge fire door, but it is about
the safety of everyone. When a fire occurs, the refuge fire door
can play a role of fire isolation, which helps to protect people's
lives.
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.
