【 Weak current College 】 Mall Builder fires---Power By 【 China power house network 】

As China's modern urban construction fast development, major shopping malls in new, expanded and reconstructed construction works gradually increased, to accompany the fire is on the rise. Recent years, the city fire accidents in construction sites, construction workers and residents in the vicinity of personal and property security constitutes a considerable risk. Therefore, strengthen the arcade building site especially conversion or extension work site fire characteristics and fighting strategy is necessary.
　　
First, the shopping centre building site fire characteristics
　　
1, blaze, burning fast. Fire resistance of construction sites, in addition to the hand along the outside of the foot frame spread, Interior stairs, stair, various shaft, patio and so are the spread of fire. In addition, the construction site use and storage of large quantities of plastic molding die shells, wooden template, insulating grass curtains and waste lubricating oil and other flammable materials and articles, some scaffolding is also built with combustible materials, these items are increased combustion of load.
　　
2. disposal is difficult, a long time. Multiplayer arcade building site area, span, such as night fire, firefighters do not know the internal structure and internal settings, enter the internal fighting is very difficult to fight, internal spark, extending the extinguishing time. Construction site around the stacked sand, bricks, steel, templates, and other building supplies make fire vehicles cannot close. November 13, 2005 2: 40 p.m., Shanxi Taiyuan Nanneihuan Street under construction of wealth building 13th floor, fire, fire officers and soldiers fighting till the fire control.
　　
Fire channel 3, domes, staff easy casualties. Building site staircases and entrances are often stacked building waste or other building materials, especially some combustible, flammable, fire resistance, seriously impede the construction workers and firefighters downlink and uplink and smooth implementation of fire rescue. In fighting building site fire, firemen are vulnerable: leap pipe Groove (well) inadvertently "tripped"; the floor is not blocking the holes, no protection bar of staircases and scaffold fell off and "hurt"; being hit by falling objects are "crushed" pounded the nails and other sharp objects and "injury"; the construction of a gas cylinder explosion which is "burned or wounded", etc.
　　
4. Provisional summary construction. Construction site work shed, warehouses, dormitories, offices, canteens, mostly temporary flammable building, and large work shed adjoining together, separated by a lack of fire safety. 2006 12 March, Suzhou Xu Jiang huating builders on a shed broke. Because the work is made of sandwich's color steel plate construction, fire resistance, was on fire, fires will soon work on the second floor was devastated.
　　
5, expanded and reconstructed in the shopping centre adjacent Street Mall, shop more, once a fire can easily be adjacent shopping malls, outlet ignition. If phase II project of Handan Kant is away from the workplace around town, Kant NPP site fire after partial igniting frontage shop.
　　
Second, market building site causes of fires
　　
1. welding of fire is more prominent. In 1998, Xi'an little Swan House, a house under construction on the building site for welders job inadvertently, fire, because of the lack of fire-fighting equipment on site, plus the construction personnel lack the most basic knowledge about fire fighting, fire was rapidly expanded, the fire department sent dozens of fire, hundreds of officers, after more than ten hours of arduous struggle before the fire, the fire resulted in the loss of tens of million RMB. 25 December 2000 East late, Luoyang commercial remodeling process, both as a layer when molten slag welding splashes in the negative on the second floor of the piece of red cloth of fire, upstairs 309 people inhaling toxic fumes of severe poisoning suffocation. 17 January 2005 15: 00 am, the most prosperous region in Nanjing at the mouth of the mountain a high-rise shopping centre building site for welders welding sparks when the job falls below the elevator on the ignite flammable of tarp tarpaulin disaster, persuaded to stop watching caused. Such as construction using the fire caused by welding, building site fire of 45%.
　　
3. the use of fire power, management, electrical equipment does not comply with the requirements. The construction period is often necessary to take the electric welding, flame cutting, torch, temporary use of fire, mechanical equipment and lights and more, power consumption, and temporary chaos, chaos phenomenon received a wire, all these are easy to start a fire.
　　
4, construction unit, staff mobility in large, security conscious weak. A large project, often several units and hundreds or even thousands of common construction, construction workers, most of the lack of knowledge about fire safety management to keep up with the worker casually throw cigarette smoking is a phenomenon repeated, onsite fire fighting equipment, fire hydrant around, there is no obligation to fire, fire resistance, are often unable to fire fight in the early stages, but also easy to cause the disorder, affecting the fire-fighting the fight. February 20, 2006 19, Handan Kant market phase site in case of fire, the cause of the fire department at the site of temporary workers in four layers in the southeast corner of settlement with illegal incineration of waste, the fire is not off, leave, leaving the fire originated around fuel fire ignition, too far in the area of 8000 square meters, with direct economic loss 23.17 million,
　　
Third, market building site fire fighting measures
　　
1. grasp the existing equipment, enhancing first deployed forces. Shopping Center construction site in case of fire, spread fast, easy to form high-dimensional space, while the fire was burning control will ignite around the Mall or retail. Therefore, the shopping centre building site fire extinguishing strengthen first deployed force mobilization is very important, is usually able to satisfy the control of the spread of fire development and meet the needs of stereo operation. The first deployed forces to power, large tonnage of fire vehicles, vehicle fire climb in the high-pressure pump.
　　
2, scientific management, decisive decisions. The fire commander shall, in accordance with the fire and the fireBuilding, carefully lay the victories. To scientific judgement and accurately select main direction, the first group arrived at the scene of the fighting forces deployed in the most critical and most needed, to prevent fire spread around. If the second site, Handan city, Kant, the Commander to fire the first deployed forces deployed in Kant's first stage and second stage site adjoining Office, blocking the fire spread to Kant's supermarkets. To the full estimated to occur, the mobilization of reinforcements, ready to play in tackling or things mutation, timely release emergency command. Consider the fire scene complexity, maintain order and evacuation fire extinguishing, fire in mobilizing force arrived at the scene at the same time should also be public security, traffic police, water, electricity, medical care, first aid and other social forces to reach the scene in disposal. According to the fire, seize the opportunity, resolute decision to actively take such attack sieges, the clip method to fire. To ensure a good fire order to delineate the scope of good vigilance so as not to affect the firefighting and rescue operations.
　　
3. look for water in a timely manner to ensure adequate fire water supply. As a result of shopping at a construction site in case of fire, was on fire, easy to form a large fire, arcade building site in case of fire, maintains a constant supply of water, meet fire place desired water consumption is the key to success in the battle. Due to the construction site near the General non-water, should be taken with a long series of water-supply, water carrier. When the water height more than cycling ability, should take many cars coupled high power supply or use of fire.
　　
4. take full advantage of the construction site equipment and lift trucks. The first batch of forces arrived at the scene, should make full use of fire fighting aerial ladders, a car and a facilities combined with the construction site of the scaffold, lift, crane, hoist and housing infrastructure, settings, such as elevators, stairs, managed to climb, rescue fire-fighting. Rapid occupation of favourable position, close to the fire, is directly related to fire fighting efficiency. And in the use of scaffolding, in order to prevent the spread of fire and up along the scaffold scaffolding collapse, should take the lead in trying to dismantle scaffold on combustible material or layout for cooling water gun.
　　
5. develop effective tactic rational arrangement of power. The ascent to occupy a favorable terrain and close to the fire, on the one hand use vehicle-mounted water cannon, fire quickly destroy the periphery, get active, on the other hand in the shaft and fire near the door and window layout water gun, stop the fire, the fire under control within a certain scope, quickly forming a "clip" attack, assault combat situation, to control the fire, the aim of eradication of fire. In combat, to actively implement the "first rescue, fire-fighting; after the first priority, after the first control, General; eliminate" tactical principles.
