When designing the interior decoration of civil buildings, it is necessary to strictly follow the requirements of the current standard "Fire Prevention Code for Interior Decoration Design of Buildings", select suitable interior decoration materials and proper construction methods to prevent problems before they occur.      The fire prevention design of interior decoration of civil buildings shall comply with the following general regulations:

(1) In actual engineering, sometimes due to functional needs, when some porous or foamed plastics are locally used on the ceiling and wall, in order to reduce smoke and toxic gas hazards in fire, the thickness should not be more than 15mm, and the area should not exceed 10% of the ceiling or wall area of the room.

(2) When a fire breaks out in a windowless room, it is difficult to detect at the initial stage of the fire, but by the time it is discovered, the fire has often already spread;      Indoor smoke and toxic gases cannot be eliminated in a timely manner;  It is difficult for firefighters to conduct fire reconnaissance and extinguishing. Therefore, except for underground buildings, the combustion performance level of interior decoration materials in windowless rooms should be increased by one level on the basis of relevant regulations, except for Class A.

(3) The library, reference room, archive room, and rooms storing cultural relics should use Class A decoration materials for their ceilings and walls due to the large amount of flammable and precious books, materials, and cultural relics stored inside;

(4) Large and medium-sized electronic computer rooms, control rooms, telephone main rooms, and other rooms where valuable equipment is placed should use A-grade decoration materials for their ceilings and walls, and use decoration materials not lower than B1 grade for the floors and other decorations.

(5) The fire pump room, smoke exhaust room, fixed fire extinguishing system steel cylinder room, distribution room, transformer room, ventilation and air conditioning room, etc. are all rooms for various power equipment. To ensure that these equipment can operate normally in the event of a fire, all interior decorations should use Class A decoration materials.

(6) To ensure that the vertical evacuation routes within the building are protected in the event of a fire, the ceilings, walls, and floors of stairwells without natural lighting, enclosed stairwells, and smoke proof stairwells should be decorated with Class A materials.

(7) When a building is equipped with an atrium, arcade, open staircase, and escalator that connect the upper and lower floors, due to the high spatial height of these areas, some of which connect several or even more floors, once a fire occurs, it can quickly spread upwards, causing great difficulties in personnel evacuation and firefighting work. Therefore, the ceilings and walls of the connected parts should use A-level decoration materials, and other parts should use decoration materials not lower than Bl level.

(8) The function of the smoke barrier is to slow down the speed of smoke diffusion and improve the smoking effect of the smoke exhaust outlet in the smoke prevention zone.  When a fire occurs, the temperature of the smoke can reach over 200 ℃.      If it comes into contact with combustible materials, it will generate more smoke and even cause combustion.  To ensure that the smoke barrier wall plays its due role in a fire, A-grade decoration materials should be used for production.

(9) The deformation joints (including settlement joints, expansion joints, seismic joints, etc.) run through the entire building from top to bottom, and the joint material also has combustibility.      To prevent the longitudinal spread of fire, the base layer on both sides should use A-level materials, and the surface decoration should use decoration materials not lower than Bl level.

(10) To prevent sparks or high-temperature molten beads generated by the distribution box from igniting surrounding combustibles and to prevent heat transfer from the box from igniting wall decoration materials, the distribution box inside the building should not be directly installed on decoration materials below B1 level.

(11) When the high-temperature parts of lighting fixtures are close to non Class A decoration materials, fire prevention measures such as insulation and heat dissipation should be taken.      The distance between the high-temperature parts of lighting fixtures and non Class A decoration is determined based on the amount of heat generated by the lighting fixtures during use, the length of continuous working time, the combustion performance of the decoration materials, and the effectiveness of different fire protection measures.  The combustion performance level of materials used in lighting fixtures should not be lower than B1 level.

(12) In public buildings, wall hanging, sculptures, models, specimens, etc. are often included as part of interior decoration design.  In order to prevent these decorations from causing fires, it is stipulated that wall hanging, sculptures, models, and specimens made of B3 level decorative materials should not be installed in public buildings.   When necessary, they should not be placed near fire or heat sources.

(13) The horizontal evacuation corridors and exit halls on each floor of the building are the main escape routes for personnel in case of fire, so the ceiling decoration materials should use A-level decoration materials, and other parts should use decoration materials not lower than Bl level.

(14) In order to ensure that the fire hydrant plays a full role in fire fighting, it is required that the door of the fire hydrant box inside the main building should not be covered by decorations, and the color of the decoration materials around the fire hydrant should be clearly different from the color of the fire hydrant door box.

(15) To ensure the functionality of fire protection facilities and evacuation signs, the interior decoration of buildings should not obstruct fire protection facilities, evacuation signs and exits, and should not hinder the normal use of fire protection facilities and evacuation corridors.

(16) There are many sources of fire in the kitchen, and strict requirements should be placed on the combustion performance of decoration materials.   The kitchen inside the building should be decorated with A-grade materials for its ceiling, walls, and floor.

(17) Restaurants and research laboratories that frequently use open flame appliances have a high risk of fire, so the combustion performance level of decoration materials should be raised by one level on the basis of relevant regulations, in addition to Class A.
