【 Weak current College 】 construction interior trim fire safety hazards and solutions-Power By 【 China power house network 】

With the rapid development of China's market economy, increasing living standards, the construction interior trim and more colorful, to create a warm, comfortable working and living environment. But because decorated in using vulnerability combustible materials, lack of the necessary fire safety precautions, resulting in the engineering behind congenital security risk. This article is mainly for building fire safety hazard exists, make some superficial preventive measures.
　　
I. common construction interior trim fire hazards:
　　
1, a quantity of use of combustible, flammable decoration materials. This is the decoration of the biggest problems. Many hotels, shopping malls, song and dance halls in pursuit of luxury, style, and makes extensive use of combustible, flammable decoration materials. Wood joist, combustible ceiling panels, foam boards for ceiling decoration; with combustible, flammable wallpaper, redbud will make wall decoration; with flammable carpets for floor decoration; with flammable decoration cloth for curtains and curtains, bed cover, seat cover, plywood, fibreboard for Panel decoration; sofas, bedding in large quantities with polyurethane foam, etc. As a result of the massive use of combustible, flammable decoration materials, extinguishing, fire load, fire development strongly.
　　
2, electrical equipment and wiring design, installation is not the norm. This is the decoration of universal issues. Dance halls, amusement Hall installed lots of lighting, sound equipment and machinery moving scene. Electrical equipment, line complex. When you install a lot does not conform to fire requirements. Lighting decoration does not adopt the necessary heat insulation, thermal measures. Incandescent, fluorescent rectifiers from ceiling, curtains and other combustible material too close, the wire did not use protection wear, no junction box, connector, switch, knife, extremely easy because the exposed conductor short-circuit cause a fire.
　　
3. the quality of the decoration, decoration construction site confusing. According to statistics, the country has been registered in the decoration of the enterprises has reached nearly 10 million and 600 million people. Some of the decoration company personnel are not fixed, no professional and technical personnel, with some temporary recruitment of mobile construction, there are a large number of 3-5, 10-person underground decoration guerrillas, self-employed workers. These personnel without safety training for the job, resulting in a worker's fire safety awareness among economic interests, in order to reduce the repair material grades, or inferior materials for decoration, or engineering construction design, Jerry, change down some decoration company personnel are not fixed, no professional and technical personnel, with some temporary recruitment of mobile construction. These personnel without safety training for the job, resulting in a worker's fire safety awareness among economic interests, in order to reduce the repair material grades, or inferior materials for decoration, or when the project construction, design and workmanship, reduce technical standards, to works under the birth risk. buried Construction site repair material piling up messy; painting, coating, solvent custody over poor, sawdust, wood shavings, wire mess messy and swing, cigarette butts, vulnerable to fire at the construction site.
　　
4. the fire department monitoring surface is limited, leak trial fitting. Partly renovated units do not understand the fire Statute, I wonder if the decoration but also reported the fire department audits, more units of drilling the laws and regulations of the vulnerability, the Fire Department because employment is limited, not all social renovation works supervision, resulting in a number of vulnerabilities that lead to some unlawful decoration is not constrained, causing problems for a long time without modification, to become the cause of accidents.
　　
Second, fire management strategy
　　
1, strict control of combustible, flammable decoration materials. Construction interior trim materials by using parts and functions are divided into seven categories, they are the ceiling decoration materials, wall decoration materials, surface decoration materials, room decoration materials, fixed furniture, curtains curtain window cover decorative fabrics and other decoration materials. Repair material combustibility refers to how easy the material caught fire and the fire spread speed after the flame is directly related to the fire risk size and fierce fire development program, is the most important decoration materials, fire protection requirements. Under the construction interior trim design fire protection standard law, the repair material combustibility is divided by A non-combustibility B1 B2 B3 combustible nonflammable flammability requirements for four types of, and positive selection level a noncombustible materials and B1 level nonflammable materials.
　　
2. specifications for electrical equipment and wiring of the selection and construction and installation. In electrical equipment and wiring of the selection and construction of wire voltage level should be higher than the line voltage, current section of the security should be greater than the load current and meet the requirements of the mechanical strength, insulation should be consistent with the line installation and environmental conditions. Line heat source should be avoided, as must, should be insulated to traverse the surrounding temperature not exceeding 35 ° C. Line laying metal device embalmment should be done. Various out wiring should be laid horizontally and vertically. Wire and wire, pipe cross at set insulation tube or isolation. Wires should minimize joints. Traverse in connectivity and branch office, should not be subject to mechanical stress. Conductors and electrical terminal connection to secure compaction. Large cross-section wires connection should use wires with metal terminals. If you touch the copper and aluminum Terminal, copper terminals make swiping the Tin. Traverse through wall should be mounted over the wall tube ends out of the wall surface is not less than 10mm. Line insulation resistance should not be less than 1000 per volt operating voltage Ω. Lighting lamps of high-temperature parts, when close to non-A level of repairs materials should take heat insulation, heat, fire protection, lighting the material combustibility rank should not be less than B1 level.
　　
3, to intensify its awareness-raising construction party, construction of fire safety awareness and sense of responsibility. For a growing number of new and reconstructed decoration engineering, only intensify its awareness, increase community fire safety awareness, enhance social responsibility, to make the construction party consciously to fire agencies declare their architectural decoration design review and acceptance of fire.
　　
4, combined with relevant departments, and increase the audit, increasing construction inspections, strictly control the quality of the project. Increase supervision of renovation industry, centralized governance "three" decoration companies.

We should present decoration industry targeted investigations, and according to the actual situation of joint-building sector, business and other related departments to centrally control the renovation industry, some qualified decoration companies be banned, not perfect decoration companies to transform and improve the industry's security technical content, reducing the chance of fire occurred.
