Hidden danger of high-rise buildings: record of fire in Shanghai residential buildings

Editor: Solemn choreographer: Zhangshuo Hou Jingma Zhang Qinsi camera: Shen Yu xiaoming Today we are looking at 1115 major fire accidents in Shanghai. More than two o'clock in the afternoon yesterday, located in the Shanghai Central Jiaozhou Road 728 Lane 1th, a 28-storey high-rise apartment building burst into flames. As of 9 o'clock in the morning today, the massive fire has killed 53 people and 70 others are being treated in hospitals, 17 of them seriously.　　Let's take a look at what happened when the fire started. November 15 around 14 o'clock, a high-rise residential building in Shanghai Jingan a big fire, causing significant casualties.　　This is the scene of the accident 15 minutes after the fire happened. The 28-storey residential building was once wrapped in fire and smoke.　　Dozens of of fire engines constantly sprayed water into the building, and police helicopters circled overhead.　　Constant burn residents were rescued.　　After the fire, Shanghai Public Security, fire, health, emergency office and other departments immediately dispatched, rushed to the scene to dispose of the fire fighting and rescue work. Hundreds of firefighters from more than 20 fire squadrons entered the fire building in batches, looking for each floor and room, searching for the victims in an inch of rubble.　　At the same time, also holding a glimmer of hope to find the survivors of the fire. The fire-fighting foam on the first floor has been deep and knee-wide as the water falls down in the burning building.　　The two elevators in the fire building have been stopped and firefighters are walking up from two fire stairs to search each room.　　Oriental Taiwan reporter Sunk Jiong Sunke: Firefighters are one of the family to break open the door, looking for possible survivors, we see the rear firefighters are using some demolition tools to rescue. Sunke: What about upstairs?　　What about the seven floors?　　Fireman: Each floor has the division of labor of each floor, each squadron division of labor.　　Sunke: How many people are you searching now?　　fireman: We have searched it several times, and we have been fully launched. Firefighters introduced, in the room corner, toilet, ruins, there may be the bodies of the victims.　　In times of crisis, stranded residents may opt to shut their doors to avoid smoke and fire, so firefighters have to dismantle the closed doors. Reporter: Now we have searched for a few firefighters: now we (search and rescue) the second time the site is located in downtown Shanghai Jiaozhou Road near Yuyao Road, the fire building was once wrapped in smoke and fire. The scene of the fire was full of flames, smoke, ashes falling down, shattered glass fragments, and the air was filled with pungent burnt smell.　　Firefighters continue to rescue from the fire inside the public, although the ground water temperature of forty or fifty degrees, but in front of the fire fighters did not retreat, still time and again with the fire, and the race to life.　　To help the wounded, rescue helicopters will rescue workers directly from the high floor to participate in the rescue, because the continuous rescue time more than 3 hours, some rescue workers have collapsed suffocation situation, but they did not stop, but with a towel wrapped around the head, continue to insist on the coma wounded carried out the building. Shanghai Cityand Jingan leaders and cadres in the first time set up a command center and Working Group, from the scene rescue, medical rescue, public security control, logistics and other aspects to take emergency measures. Expert analysis of the scene, the fire building four weeks filled with scaffolding, surrounded by a large number of flammable and combustible nylon nets, pedal is a combustible bamboo plate, so that the fire quickly to the vertical direction and surrounding spread, in a very short period of time to form a large area of intensive fire. At the same time, the site construction site larger, wind to help the fire, accelerated the spread of fire. The reporter learned from many points that this is part of the Shanghai Jingan Government's plan to improve the housing project, which has been piloted in the community since September. A high-rise residential building built in 1998, a total of three 28-storey high-rise buildings, in addition to the accident 3rd building for commercial housing, the other two are Shanghai Jingan teachers dormitory building. There are people living in the vicinity told us that the construction team since the beginning of a half month to enter the community construction, in three high-rise buildings outside the wall to build scaffolding, the external wall for energy saving and environmental protection, to increase the insulation layer.　　Insiders speculate that this kind of bubble-like things are likely to be extruded polystyrene foam board (XPS), a continuous closed-hole foaming rigid foam board, although it is an environmentally friendly insulation material, but with a combustible, once ignited, burning quickly. 15th 6:30 P.M., the fire was basically extinguished.　　By the Central Committee, the State Council commissioned, State Councilor, Ministry of Public Security Minister Jianzhu 15th late-night rate of the State Council working group rushed to Shanghai to guide Fire Rescue and rehabilitation work.　　16th 1 o'clock in the morning, Jianzhu at the scene of the fire site, to understand the latest progress in search and rescue work.　　In the news that the fire officers and soldiers have been to the building for a number of dragnet search, still do not give up the final effort, he stressed that the fire has been extinguished, the current most urgent task is to do their best to search for survivors, do not miss any one corner, do not give up any glimmer of hope The building of the fire, for the reinforced concrete structure, the height of 85 meters, building area of 18472 square meters, December 1997 completed, March 1998 occupancy. The bottom of the building is a shop, 2 to 28 storeys for residential, of which 5 units, 156 households, actually live more than 440 people. After the fire, the city of Shanghai overnight mobilization of medical resources, the full rescue of injured personnel, a number of municipal, district-level hospital emergency opened up a green channel.　　Let's take a look at the treatment. Shanghai Jiaozhou Road Residential building after a serious fire, about 100 injured were rushed to Shanghai Jingan Center Hospital, East China Hospital, Huashan Hospital, Ruijin Hospital, Putuo People's Hospital.　　Medical institutions have opened a green channel to start emergency plans, Shanghai Medical Emergency Center also quickly mobilized 30 ambulances rushed to the scene, and strive to treat the wounded in the first time.　　Putuo District Central Hospital after the accident, received 5 persons from the Putuo People's hospital turned over the injured, and in the night around eight o'clock to send hyperbaric oxygen cabin, remove the harmful gases inhaled in their bodies. Putuo District Central Hospital deputy Dean Zhao Deqiang Zhao Deqiang:The five casualties are mainly caused by the inhalation of fire smoke after the lung gas poisoning, the main symptoms are sore throat, chest tightness, dizziness. In order to do a good job in the treatment of the wounded, the hospital evacuated more than a few skilled medical staff, and the patients to carry out paired treatment. In hyperbaric oxygen cabin, paramedics are accompanied by the wounded to cope with possible contingencies.　　Among the five wounded, the most gripping is a 4-year-old small wounded, beautiful, the fire happened when the family is at home, father held her from 16 floor to 15 floor, and then escaped from the safe tunnel fire.　　Reporter: Now the beautiful dad and Grandpa and Grandma are in Ruijin Hospital for treatment, fortunately they are not life risk, and beautiful now also quiet down, she just into the oxygen cabin has been crying. At 10:30, the wounded began to hatch, of which two were young men.　　After two hours of oxygen inhalation, the people's complexion has changed.　　Journalist: How many floors did you escape?　　Wounded: 18 floor, from the outside with scaffolding overturned, jump to nine floor, and the other people's Glass kicked broken, and then from the emergency channel out. The hospital said that although the wounded are in stable condition, but still need to be in the hospital for a few days observation, confirmed that no obstruction can be discharged. The Health Department organizes the city-level experts to comprehensively comb the fire accident in the hospital patient. In addition to the Central hospital in Putuo district received 52 patients, Ruijin, Huashan, east China, Jingan Center Hospital and other hospitals, have received dozens of injured.　　In Shanghai Jingan Center Hospital, the reporter saw, starting from yesterday 2:45 P.M., about every 5 minutes, there are several 120 ambulances to transport the wounded arrived here, currently admitted 52 wounded.　　Jingan Central Hospital Party committee deputy secretary Li Tianya Li Tianya: Most patients are suffocated, Reporter: are suffocating?　　Li Tianya: Yes, the patient's mood is relatively stable.　　In the emergency room, the reporter saw the doctor to take CPR for the severe wounded, and some of the patients have been transferred to the lounge, currently they only need a lot of water, and no life risk. Shanghai Jingan Center Hospital and other hospital medical personnel overnight for patients to vacate the ward, the deployment of oxygen cylinders, monitors and other equipment. After triage and emergency treatment, the individual injured persons were sent to the intensive care unit and the vast majority of the injured were diverted to the ward for further treatment. In response to the post-traumatic stress response of some of the wounded, the medical department specially arranged for counseling and medication. It is understood that most of the wounded are mainly body surface burns, fractures and inhalation injury.　　The hospital said that the Shanghai Municipal Health Bureau had mobilized the city's best medical experts and equipment, and went all out to safeguard the life and health of the wounded. In East China Hospital in Shanghai, the hospital for each of the wounded wound bandage, vital signs check, in addition to 10 more serious injured hospitalized, but also vacated a special venue for treatment of 10 patients, for the patient equipped with oxygen cylinders, monitors. Some of the injured have suffered post-traumatic stress response, and psychologists have been grooming them.and drug therapy. 1:30 A.M., Jianzhu rushed to Shanghai Ruijin Hospital to see the wounded.　　In the ward, Jianzhu kindly hold the wounded hand, carefully inquired about their injury. 2 o'clock in the morning, Jianzhu presided over a meeting to convey the important instructions of general Secretary Hu Jintao and Premier Wen Jiabao, to hear the report of the Shanghai municipal government, and to announce the establishment of the "11 15" special fire Investigation Team in Shanghai, the State Council.　　He said that after the fire accident, the party Central Committee, the State Council attaches great importance to the Shanghai municipal government to organize fire fighting and personnel rescue, efforts to reduce casualties, the disposal and rehabilitation work is being carried out.　　Jianzhu requirements, continue to do their best to do the search and rescue work, do everything possible to cure the wounded, reduce the death due to injury, injury, and properly do the aftermath, thoroughly identify the cause of the accident, clear nature, cognizance of responsibility, according to the law serious treatment.　　At present, Shanghai Jing ' An district, the regional government has been affected by the serious fire residents to the nearby hotel, and the implementation of food and lodging issues. Today, the Shanghai municipal government set up a 11 15 fire disaster Rehabilitation management team, by the party committee deputy Secretary, mayor Han Zheng as leader. The cause of the accident has now also been preliminarily identified, is caused by illegal operation of unlicensed welders, a fault, at present 8 suspects by the public security organs of criminal detention. According to FEI, director of Shanghai Fire Department, the fire occurred, the building is the implementation of energy-saving comprehensive renovation project, the general contractor for the Jingan Construction Corporation, subcontracting party for the Shanghai Jiayi Decoration Company.　　But how can this fire, which has been ignited two o'clock in the afternoon, be extinguished at 6:30? Yesterday afternoon after the fire, 14:15, the Shanghai Emergency Linkage Center received a fire alarm, the Shanghai fire Station to take out the police, mobilized 45 squadrons of various fire 122 vehicles, including ladder truck, lift 17 vehicles, fire officers and soldiers more than 1300 people. However, when they arrived at the scene of the fire, they encountered insurmountable difficulties.　　Take a look.　　After the fire occurred, the Shanghai Fire Bureau quickly came to use the world in the advanced level of fire fighting equipment, put the most advanced equipment and the most capable force, 10 vehicles fire engine emergency fire, but the fire ladder can not reach the 22-storey position, 22-storey fire over a short period of time difficult to control.　　In order to increase the rescue power, a helicopter has been hovering around the building, but because the fire is heavier, it is still unable to access the building. Li, a researcher at the Center for Public Safety at Tsinghua University, told us that the "Fire code for design of high-rise civil buildings" will be 10-storey and 10-storey residential buildings, and more than 24m of public and comprehensive buildings, known as high-rise buildings, has been a high-rise building fire suppression is an international fire problem, At present, we can only rely on daily precautions.　　In the event of a disaster, the rescue will have great difficulties. The rescue process of 1115 mega-fire in Shanghai also revealed the worldwide fire-fighting problem of high-rise buildings. Because the floor is high, the volume is big, the personnel is dense, the high-rise building itself fire hidden danger is more.And once the fire, it is very easy to produce chimney effect, fire spread quickly, personnel evacuation difficulties, save difficult.　　So, how to maintain the safety of high-rise building in the world? Li told us that at present high-rise building live in the rescue by a number of restrictions: On the one hand, height of the vehicle is limited, on the other hand, the helicopter rescue will also receive dust, hot airflow, smoke and other restrictions.　　In China, the supervision of high-rise building fire prevention and control measures is not in place, many high-rise building fires are due to the building materials and construction code problems. With the acceleration of China's urbanization process, land resources become more and more scarce, many cities high-rise buildings have been built more and more long, it seems to have become a general trend of development, only Shanghai high-rise buildings this year has reached more than 19,000 buildings, high-rise building nearly 1000.　　As a member of the building Fire Prevention and Zoning Committee of the Chinese Architectural Society, the Hu of the College of Architecture and Urban planning of the Northern Industrial University has its own personal experience. Bing said that the brilliant skyscrapers, has become a symbol of urban prosperity and civilization, but there are also worries behind the boom, our fire fighting capacity has not as the rise of high-rise buildings and the longer the "high". At present, most of China's high-pressure water gun and fire ladder height is very limited, the highest can only reach seventy or eighty meters height, but the general high-rise building height of more than three hundred or four hundred meters, when the high-rise building fire, the fire spread quickly, the personnel evacuation is more difficult, even the helicopter is sometimes helpless.　　The development of high-rise building and the limited ability of fire fighting have become a pair of contradictions which need to be solved urgently.　　Hu told us that in the United States on average, more than 7,000 high-rise building fires every year, almost 20 a day, but the United States on the fire design of high-rise buildings and safety management of a lot of experience can be worth our reference. Half-hour observation: Shanghai fire interrogation of high-rise building times now 1115 of the cause of the fire has been preliminarily identified, and from the previous program, we also found that the accident has already been hidden. Fire building outside the wall in the construction of the use of a lot of flammable insulation materials for the construction of bamboo pedal and nylon nets also easy to see fire on. These factors coupled with the illegal operation of the unlicensed welder, eventually led to a tragedy. How to ensure the fire safety of high-rise buildings is indeed a real problem, in the event of a fire, the existing technical means to quickly extinguish the fire there are many obstacles. Such a dilemma for us to use the system to prevent security risks put forward higher requirements, both in architectural design, material use and fire facilities equipment, strict norms, practical implementation, preventive measures, but also in the day-to-day use of maintenance, always improve safety awareness, to eliminate any fire hazards. Shui, every catastrophe should spur us to build a stronger safety net, not just the pain.
