1 General provisions
1.0.1 This clause specifies the purpose and basis for the development of this Code. This Code is formulated to ensure the fire safety of the interior decoration of the building and to prevent and reduce the hazards of building fires. It requires the personnel of the design, construction and fire supervision departments to closely cooperate with each other. In the decoration design, carefully and rationally use various decoration materials, actively adopt advanced fire prevention technology to achieve ?€?preventing problems before they occur?€?, to prevent the occurrence and spreading of fire hazard from the positive aspects. This is extremely important for reducing fire damage, ensuring the safety of personnel lives and property, guaranteeing the smooth progress of economic construction.
This Code is compiled in accordance with the relevant provisions of the current national standards ?€?Code of design on building fire protection and prevention?€? GB 50016, ?€?Code for fire protection design of civil air defence works?€? GB 50098, etc., through investigation and summary of the actual conditions of the medium and high rank restaurants, hotels, theaters, gymnasiums, comprehensive
buildings, etc. which are newly built in recent years, combining with the characteristics and requirements of the design of interior decoration of the building, with reference to the relevant codes for design of fire prevention of buildings of some advanced countries on the fire prevention of interior decoration, combining with the national conditions.
1.0.2 This clause specifies the scope of application and the scope of non- application of this Code.
This Code applies to the design of interior decoration of industrial and civil buildings.
With the improvement of PEOPLE living standards, interior decoration has developed rapidly, with a large number of residential buildings and a very different level of decoration. The decoration of some of the residential buildings is designed and constructed in a unified manner by the building organization. In order to protect the safety of residents, the interior decoration which is designed and constructed in a unified manner by the building organization shall implement this Code.
1.0.3 According to the ?€?Fire case analysis?€? which is edited and published by the China Fire Protection Association, many fires are caused by the burning of decoration materials. Some of them are caused by ignition of bedclothes by cigarette ends; some are caused by the ignition of curtains and purdah; others are due to the burning-through of the wooden suspended ceiling and partitions after catching fire. Therefore, it is required to correctly handle the contradiction between the decoration effect and the safety of use, actively use non-
combustible materials and flame-retardant materials. For combustible or easily- combustible materials which cannot reach to the flame-retardant materials, it may use the method of flame-retardant treatment to improve the combustion performance grade. The selection of the above materials may make reference to such codes as the current national standard ?€?Requirements and mark on burning behavior of fire retarding products and subassemblies in public place?€? GB 20286.
The non-combustible materials and flame-retardant materials referred to in this clause correspond to the materials of relevant grades in the current national standard ?€?Classification for burning behavior of building materials and products?€? GB 8624.
In recent years, the number of people killed in smoke and poisonous gas from building fires has increased rapidly. For example, in the United Kingdom, the number of people who died of tobacco suffocation in 1956 accounted for 20% of the total number of fire deaths. In 1966, it increased to 40%. In 1976, it reached as high as 50%. In Japan, the Sennichi department store fire killed 118 people, including 93 peoples killed by smoke, which accounted for 78.8% of the death toll; in April 1986, in a fire in a residential building in Tianjin, 4 households 13 people were killed. In fact, the fire did not burn to their homes, even a full- filled LPG cylinder placed 2 m away from one of the doors was still safe afterwards. It is not the fire that robs these 13 lives, but the smoke and poisonous gas. In 2000, a large fire broke out in a shopping mall in Luoyang City, Henan Province, 309 peoples died because of poisonous gas asphyxia. In 2015, a cable well in a residential area in Wuhan caught fire, the 7 people who died were suffocated on the way to escape.
People gradually realized the dangers of smoke and poisonous gases in fires. Relevant departments have conducted some simulation tests and studies. The interior decoration materials that generate smoke and poisonous gases in fires are mainly organic polymer materials and wood. Common toxic and harmful gases include carbon monoxide, carbon dioxide, sulfur dioxide, hydrogen sulfide, hydrogen chloride, hydrogen cyanide, phosgene, and the like. Due to the wide variety of interior decoration materials, the amount of smoke and poisonous gases generated during combustion varies. There are certain
difficulties in quantitative control of smoke density, visibility and toxicity. However, with the further development of all aspects of work of society, this problem will be solved very well. In order to arouse the attention of designers and fire supervision departments on smoke and poisonous gases, in this clause, it proposes the basic principle of ?€?avoid using?€? the interior decoration materials that generate large amounts of smoke or poisonous gases.
1.0.4 The design of interior decoration of the building is a part of the architectural design work. All types of buildings shall first meet the fire protection 4 Typical places
4.0.1 On the basis of the original code, according to the principles from important to minor, the clauses are reorganized.
The fire-fighting facilities inside the building are designed and installed according to the requirements of the current relevant codes. The maintenance management shall be strengthened in order to ensure its quickness, safety, reliability during operation once needed. However, in order to pursue the effect of decoration, some units arbitrarily reduce the width and number of safe exits, evacuation exits and evacuation walkways, arbitrarily change the location of fire-fighting facilities, arbitrarily increase the partition walls, which affect the range of effective protection of fire-fighting facilities. In order to ensure the use function of fire-fighting facilities and evacuation signs, this clause is compulsory. For the design of fire prevention of building which is necessary to change, in addition to the implementation of the provisions of relevant standards, it shall also follow the laws and regulations, as well as the prescribed procedures. 4.0.2 Fire hydrant box?€?s door installed inside the building are generally located in a more conspicuous position, the color is also conspicuous. Through a survey of a large number of renovation projects, it was found that in order to highlight the decoration effects, in such places as the public regions of many high-rank hotels, office buildings and so on, the fire hydrant box?€?s door is covered in the wooden cabinet; some other organizations decorate the fire hydrant box?€?s door almost the same as the wall surface, only the red Chinese character marking is set on its surface; meanwhile, based on different decoration styles, the font, size and position are different accordingly, which cannot be viewed if not near. These practices have created obstacles to the timely access of fire hydrants and are not conducive to standardized management. In order to give full play to the role of fire hydrants in fire-fighting, the provisions of this clause are amended and listed as compulsory provisions.
4.0.3 This clause is compulsory. When designing the decoration of building, it is necessary to ensure that the evacuation sign and the safety exit are easily identifiable, so as to avoid doubts and misunderstandings of the personnel in an emergency situation. Therefore, it shall not use mirrors, glass and other reflective materials for decoration in the vicinity of the evacuation walkway and the safety exit. At the same time, considering that the ordinary specular reflective material is easy to burst under the action of high-temperature flue gas, whilst the hot flue gas is generally suspended in the building, so such materials are also restricted for the ceiling.
4.0.4 This clause is compulsory. The horizontal evacuation walkways and the safety exit foyer at each floor of the building are the main passages for the escape of personnel in the fire, thus it specifies the combustion performance of cleaning. The most commonly used materials are ceramic tiles, stone materials and paints. The requirements of this clause can be achieved.
4.0.12 This clause is compulsory. With the development of China?€?s tourism industry, many high-rank hotels and restaurants have been built. Some
restaurants provide a variety of hot pots, some special-flavor restaurants use a mobile dining car with a gas stove. The hotels and restaurants have large population flow, so it is difficult to manage them, the use of open fire increases the hazard of fire. Therefore, it requires one grade higher for the indoor decoration materials as compared with that of similar buildings.
4.0.13 This clause is compulsory. Civil buildings such as hotels, shopping malls, office buildings, etc. all have warehouses or storage rooms, which store all kinds of combustible materials. Because there is no special person to take care of, there is a greater risk of fire, so this clause makes compulsory requirements for the fire protection grade of the decoration materials.
4.0.14 This clause is a new addition to the exhibition venue. In recent years, the exhibition economy has developed rapidly, the exhibition venues are temporary, versatile, and have other unique features. Therefore, its fire protection of decoration is specially listed into a compulsory clause.
1 The layout design of the exhibition area, including erection, scenery, etc., uses a large number of decoration materials. In order to reduce the fire load, it makes requirements for the exhibition stand which is used for
exhibition.
2 The catering operation area with electric heating equipment in the
exhibition hall may not be fire-separated from the exhibition hall. The wall surface and the operation bench?€?s surface close to the electric heating equipment shall be made of grade A materials, in order to prevent causing fire and to prevent the spread of fire.
3 The exhibition hall is characterized by intensive personnel, more
combustible materials, large power consumpt...
