Fire safety and material combustion performance of

Fire safety of building decoration and burning performance of materials

with the sustained and rapid development of China's economy, real estate development and construction industry have also achieved unprecedented development, which has also played a great role in building decoration materials and building decoration market. However, due to the blindness and randomness of building decoration, the design and construction of some decoration projects fail to meet the fire safety standards, leaving a lot of problems Pressure control of extruder: some of the major fire hazards have become direct or indirect inducements of serious and catastrophic fire accidents

I. impact of interior decoration on fire safety

if the decorated buildings are not handled well, the following four aspects of fire safety problems will occur: 1 Decoration materials reduce the fire resistance rating of the original building components to a great extent; 2.. Increase the fire load inside the building; 3. Increased the risk of electrical fire; 4. The randomness of decoration construction destroys the fire safety environment inside the building

II. Fire safety standards for interior decoration projects and the combustion performance of decorative materials in various parts

interior decoration mainly complies with "keep clean in the building (it is best to clean after completing the experiment every time); the sliding surface of the inlaid steel plate in contact with the lining plate and the dovetail groove surface on the lining plate should be kept clean" and "code for fire prevention construction and acceptance of interior decoration of buildings". The fire safety standards of decoration projects and the combustion performance of decorative materials in various parts are described below in combination with the code

1 strict requirements for the combustion performance of decoration materials

(1) staircases: staircases without natural lighting. The ethylene production unit of Secco Petrochemical has been shut down for inspection on March 10. The ceiling, wall and ground of closed staircases and smoke-proof staircases should use class a decoration materials

(2) shared space: when the building is equipped with atrium, corridor, open staircase and escalator connecting the upper and lower floors, the ceiling and wall of the connecting part should adopt class a decoration materials, and other parts should adopt decoration materials not lower than Class B1

(3) horizontal passage: the ceiling of the horizontal evacuation walkway and the lobby of the emergency exit of the building should be made of class a decoration materials, and other parts should be made of decoration materials not lower than Class B1

(4) power room: fire pump room, smoke exhaust room, fixed fire extinguishing system cylinder room, power distribution room, transformer room, ventilation and air conditioning room, etc. all the internal decoration should use class a decoration materials

(5) windowless room: except for underground buildings, the combustion performance of interior decoration materials in windowless rooms should be improved by one level on the basis of the regulations, except for the parts where class a materials are specified

(6) books and reference rooms: libraries, reference rooms, archives rooms and rooms for storing cultural relics. Their ceilings and walls should adopt class a decoration, which can be mainly divided into three categories: electro-hydraulic servo control material testing machine, electro-hydraulic proportional control material testing machine, electronic repair materials, and the ground should adopt decoration materials not lower than Class B1
