In July, 2003, 12, 10: 35, a fire broke out in the bleaching powder refined warehouse of Jiangsu Thorpe Group, located in Zhenjiang Chemical Development Zone. The direct economic loss was 683,600 yuan, and the fire area was 1040 square meters.
Basic situation of fire fighting forces
Jiangsu Thorpe Group is located in Zhenjiang Chemical Development Zone, with more than 2,900 employees, mainly including more than 20 kinds of chemical products such as AC foaming agent, bleaching powder, caustic soda and acetic acid. The bleaching powder concentrate warehouse is located on the west side of the bleaching powder concentrate workshop of Thorpe Co., Ltd., which was founded in May 2000 with a building area of 65,438+0,040 square meters and a total inventory of 380 tons of bleaching powder concentrate (calcium hypochlorite). A 6-meter-wide cement road is separated from the bleaching powder car on the east side, with an open space on the south side, a main road in the factory area on the north side and an open space on the west side. The warehouse is managed by Thorpe Group Property Management Office. On that day, the custodian was Chen Jianwei (female, 36 years old), who was responsible for the storage and distribution of concentrated bleaching powder. At 9 o'clock in the morning, the container with the car number of Su E -F4924 of Suzhou Zhangjiagang Port Transportation Company was loading bleaching powder.
Fire fighting process
12 July, 10: 35, Thorpe group bleaching powder warehouse caught fire. Upon receiving the alarm, Zhenjiang Fire Command Center 10: 37 immediately dispatched 4 fire engines from Jianbi Squadron, 3 fire engines from 14 and 3 fire engines from Special Service Squadron, and 15 officers and men to the scene to put out the fire. Thorpe Group full-time fire brigade 12 members also participated in the fire fighting. After receiving the report, Shen, deputy detachment leader of Zhenjiang Fire Brigade, immediately led the personnel on duty to the scene to organize the command. Through the efforts of officers and men, the fire was controlled at 1 1: 20 and put out at 1 1: 56, and the adjacent bleaching powder concentrate production workshop worth 30 million yuan was saved. Leaders of Zhenjiang Safety Supervision Bureau and Jingkou Public Security Bureau visited the site to assist in the investigation of the cause and loss of the fire. Leaders such as Sui Ming and Ma Yugen, deputy directors of Zhenjiang Public Security Bureau, also called to inquire about the fire situation.
Fire losses and casualties
The fire area of bleaching powder concentrate warehouse was 1.040 square meters, which caused the container truck to burn locally, burning bleaching powder concentrate 1.56 tons, and the direct economic loss was 683,600 yuan. There were no casualties.
Fire cause investigation
Immediately after the fire broke out, Zhenjiang Fire Brigade, together with the Municipal Safety Supervision Bureau and Jingkou Public Security Bureau, formed a fire accident investigation team to investigate the causes and losses of the fire. The drivers, storekeepers and stevedores were asked, and the fire scene was investigated. On the morning of July 13, the fire investigation team also specially invited three chemical experts to hold a fire cause analysis meeting. After hearing the news, Minister Ji Junxian of the Fire Department of the Corps quickly rushed to the scene to guide the fire investigation and after-treatment work.
Identification of fire location
After investigation, the fire broke out in the bleaching powder concentrate warehouse and the container truck that was loading on the east side of the road. The bleaching powder concentrate warehouse and the bleaching powder concentrate products in the warehouse were all burned, and the front of the container truck near the warehouse and a container in front were burned, leaving only traces of smoke in the container behind. All 39 1 barrel of bleaching powder that had been packed in the front container was burned. Ask the witnesses at the scene. It can be concluded that the fire is in a container in front.
Identification of fire point
In front of the container, there are heavy smoke marks on the upper part and few smoke marks on the lower part. The middle part of the rear cabin is heavy, and the metal oxide rust layer has been produced in the middle and upper part, which is reddish brown. Make sure that the ignition point is the middle part of the container.
Determination of fire cause
Through on-the-spot investigation and asking relevant personnel, it was determined that the cause of the fire was that the loading and unloading workers loaded urea in another warehouse, and when the bleaching powder concentrated solution was loaded from the bleaching powder concentrated solution warehouse to the container, the urea on it spilled into the container, and the bleaching powder concentrated solution spilled into the container during the loading and unloading process reacted chemically, causing a fire. After investigation, the chemical name of bleaching powder essence is calcium hypochlorite, which will burn and explode when it meets water, fire and organic matter. The weather is cloudy to cloudy, and the temperature is 24-3 1℃. The workers had to change their work clothes after going to work and didn't open fire on the people present. No one smoked at that time, which ruled out the possibility of bleaching powder burning and exploding in water and fire. At 9: 00 am on July 12, 14 stevedores began to load concentrated bleaching powder into container trucks. Because the weather was hot and it was late, in order to fill the container in front in the morning, Guo Junfeng, the on-site person in charge of Dingmao Branch of New District Labor Service Company, called eight loaders who were loading urea to load bleaching powder together. When loading 39 1 barrel, white smoke was found in the middle of the container. It was originally stipulated that loading and unloading workers carrying urea were not allowed to load and unload concentrated bleaching powder. Because the workers who used to load and unload urea have already left, it is temporarily stipulated that the workers who load and unload urea should change clothes, wash their hands and wipe their soles before loading and unloading concentrated bleaching powder. After loading and unloading urea that day, the loading and unloading workers did not take any measures as required, and directly loaded and unloaded bleaching powder concentrated solution. After investigation, the bleaching powder refined barrel in the bleaching powder refined warehouse was stained with bleaching powder refined, and there was a large amount of urea on the ground in the urea warehouse. After simulation test, a small amount of bleaching powder essence was sprinkled on urea, and it caught fire in a few seconds.
Fire accident responsibility
The stevedores of Dingmao Branch of New District Labor Service Company are directly responsible for the fire caused by the inadequate implementation of the system; Guo Junfeng, the on-site person in charge of Dingmao Branch of New District Labor Service Company, is indirectly responsible for the poor supervision of stevedores; Yan Xiaohua, the head of Dingmao Branch of New District Labor Service Company, is directly responsible for the inadequate education of employees. Chen Jianwei, the warehouse keeper of Jiangsu Thorpe Group, is indirectly responsible for poor on-site supervision; Liu Hongling, head of the Environmental Safety Department of Jiangsu Thorpe Group Co., Ltd., is indirectly responsible for poor inspection; Jiangsu Thorpe Group is responsible for poor management of dangerous goods.
Lessons from fire accidents
The fire was only in the car container when it caught fire. Later, because the workshop piled the bleaching powder concentrate under the eaves of the warehouse, the joint-stock company failed to find it during the inspection, which led to the rapid spread of the fire to the bleaching powder concentrate warehouse, causing the warehouse to burn down and losing 683,600 yuan. After loading and unloading urea on the same day, the loading and unloading workers failed to take any measures according to the regulations, but the group warehouse keeper failed to find out during the on-site supervision, which led to the urea on the loading and unloading workers spilling into the container, and the bleaching powder spilled into the container during handling reacted chemically, causing a fire. In this regard, Jiangsu Thorpe Group should strengthen the publicity and education of employees, strengthen on-site supervision, and truly implement the system; Conduct a safety inspection of the whole plant, strengthen every link and eliminate hidden dangers in the bud.
