Fire prevention measures for exterior wall insulation materials

The first is to improve the public's awareness of external insulation materials and achieve scientific prevention. From a practical point of view, it is impossible for people to completely deny their use in buildings because some external insulation materials are flammable. In fact, the key lies in how to use them in a safe and standardized manner. If the use of external wall insulation materials is regulated, the supervision of external wall insulation materials will be strengthened, fire extinguishing measures are complete, and safety awareness will be increased. Most fires caused by external wall insulation materials can be prevented. At present, a large number of new domestic buildings use organic external insulation materials, such as molded polystyrene boards, extruded polystyrene boards, and foamed polyurethane. Their thermal insulation performance is better than most inorganic materials, and they are mainstream building insulation materials. However, in terms of material properties, they have a low ignition point and are flammable. If a large amount of this kind of flammable insulation material is wrapped in a building, it will inevitably leave a fire hazard to the building. Therefore, relevant departments must strengthen the fire management of such buildings, and increase the public's scientific understanding of these materials to achieve scientific prevention.
The second is to strictly manage construction site construction sites to eliminate hidden safety hazards. A domestic statistical report pointed out that about 25% of fires involving building thermal insulation materials occurred during the stacking of thermal insulation materials, 65% occurred during the laying of thermal insulation materials, and less than 10% occurred in the use of buildings. It can be seen that the thermal insulation construction process of the building wall is a high risk period for fire. Supervision departments should strengthen the standardized management of building exterior wall thermal insulation material manufacturing enterprises, construction enterprises and the building thermal insulation material market, carry out certification work for wall thermal insulation systems, and introduce systems such as permits and insurance to improve the safety of building wall thermal insulation. "When carrying out fire supervision and inspection, the fire department must pass the fire prevention awareness to the building construction site management personnel, and also requires that each working face at the construction site be provided with fire water sources in case of fire self-rescue. Only strict construction On-site management can minimize the fire safety hazard.
The third is to update and improve various fire-fighting and rescue equipment and equipment, and improve the ability to attack. At present, the speed of "long height" of fire protection equipment in China is far behind the speed of "long height" of buildings. According to statistics, in recent years, there have been more than 100 super-tall buildings in China, and a number of them are under construction. Combined with the characteristics of high-rise building exterior wall insulation materials, fire has great destructive power, difficult fire fighting, and fire spreading channels. The fire department can consciously add turbojet fire trucks and high-jet firefighting in accordance with the government fire planning and the actual situation of regional economic development. Vehicles, ladder ladder fire trucks, use high-end and high-equipment equipment to enhance the emergency rescue and attack capability of the fire forces, so as to quickly extinguish the fire of insulation materials on the outer wall and prevent the occurrence of mass deaths and injuries.
