(Yang You P) Gas explosion in Daqing Refining & Chemicals Branch killed 3 people It was reported that at about 18:15 on August 14th, a gas explosion occurred in Daqing Petrochemical Branch Company of China National Petroleum Corporation and triggered a fire, resulting in three deaths and many people Injured. It is understood that the explosion occurred in the company's oil refining plant ARGG gas gas liquid separation tank. The fireball generated by the explosion and the subsequent smoke produced was as high as more than one hundred meters. The sound of explosions could be heard in areas far from 10km away. After the accident, many fire brigades in Daqing City participated in the fire fighting and rescue operations. The fire was controlled at 20:11 that day and was extinguished after strenuous efforts to save the fire. The preliminary conclusion of the accident investigation was that the inner parts of the production plant were serious because of the low friction between the two. Compared with the light bar, the high temperature has little effect on the bond strength between the rebar and the concrete. According to the research data, in practical application, the bond strength between steel and reinforced concrete under high temperature can be reduced. Table 3. Table 3 Cohesive strength reduction coefficient between steel and concrete at high temperature Temperature (*c) Decreases the optical steel bar coefficient The compressive strength of the threaded reinforced concrete, the tensile strength of the steel, and the bond strength between the concrete and the steel are the three main indicators of the bearing capacity of the reinforced concrete building components. Comparing the three, in the same high temperature effect, the same time, the loss of tensile strength of steel bars, the loss of the bond strength between concrete and steel bars is much greater than the loss of concrete compressive strength. 4 Destruction of Reinforced Concrete Components After properly designed and standardized reinforced concrete buildings, their components can be kept stable and safe under normal circumstances. Components can only fail if they are affected by factors that are not normal (outside of design considerations). The destruction of reinforced concrete building components, in the final analysis, is the destruction of the mechanical properties of the component materials, simply the main reason is the tensile strength of steel, the concrete's resistance to pressure and the bond strength of steel and concrete is destroyed or one of them is destroyed . In fires, the steel bars are subjected to high temperatures and their tensile strength decreases, including both yield strength and ultimate strength. Although the load imposed on the structure does not increase, the material carrying capacity considered under normal conditions cannot bear the original load after it has fallen. Therefore, when the high temperature of the fire continues to function for a period of time, as long as the tensile strength of the steel bar in the building structure, the compressive strength of the concrete, and the bond strength of the steel bar and concrete have fallen below the design value (informally it is the insurance The coefficient is exhausted and the structure is destroyed. 5 Conclusion In the fire field, the temperature of the surface of the building components can be measured with the instrument. After understanding the overheating time of the building, a rough understanding of the changes in the mechanical properties of the building component materials is obtained by combining Tables 1 to 3 in this paper. Of course, to properly determine the safety of the entire building, necessary technical methods, such as the use of leveling instruments, theodolites, and concrete rebound meters, should be used to observe the deformation of the buildings and their structures, so as to assist the fire commanders in conducting on-site judgments. . The above is only a qualitative analysis. The author believes that relevant research departments, such as building structure research institutions and fire protection departments, must jointly discuss and set relevant state models, and rigorously use qualitative and quantitative theories of materials mechanics and structural mechanics. Research can truly provide effective protection for firefighters in the practice of fire suppression. It can be further analyzed that when the high temperature is applied for the same time, the more the design margin is (the greater the insurance factor is), the greater the design margin of the bearing column is, the better the fire resistance of the structure is. For example, a building designed in accordance with seismic fortification should be better than the fire resistance of a building that does not consider seismic design because seismic load is considered. It is less likely to have a tipping collapse in a fire. In this way, in Fujian, Shandong, Hebei and other places where seismic design needs to be considered, the possibility of a collapse of a reinforced concrete frame building in a fire is small; conversely, in the case of a fire building that does not require seismic fortification in the original specifications in Jiangxi, Hunan, etc. The possibility is relatively large. 1st author address: No. 119 Hubin 4 North Road, Xiamen City, Fujian Province, the emergency alarm unified into 110 types of non-emergency rescue service number will be gradually unified! At 12345, it was learned from the work safety emergency management conference held in Beijing on September 12th that 110, 119, 122, 120, 999 and other alarm numbers will be unified to the 110-based Beijing Municipal Emergency Alarm Service Center. According to the material released at the meeting, at the recent second meeting of the Beijing Municipal Emergency Response Committee in 2006, Vice Mayor Yan Hongxiang disclosed that Beijing will follow the requirements of the State Council Emergency Management Work Conference when he introduces the construction of the Beijing emergency management system. Gradually the existing 110, 119, 122, 120, 999 and water, gas, heat and other alarm numbers are unified to the 110 comprehensive receiving platform. At the same time, on the basis of the municipal government's convenient call center 12345, a non-emergency Beijing rescue service center integrating consulting, service, assistance and information analysis, and coordination supervision will be established, and the city's various non-emergency rescue service numbers will be gradually unified to 12345. In addition, Liu Chunfeng, deputy director of the Beijing Municipal Safety Supervision Bureau, said that emergency rescue work for safety production is an important part of the city's emergency management of public safety incidents. At present, there are a total of 83 emergency rescue teams with a certain capacity in Beijing. There are a total of 13,500 emergency rescue workers, including 8,476 full-time staff. These emergency rescue teams have emergency rescue capabilities such as mines, dangerous chemicals, construction, and road traffic. In response to a variety of emergencies in Beijing, emergency rescue teams were dispatched 3,897 times last year, employing 11,200 people and using 8,606 vehicles. (Small party) Demolition is very convenient to handle labor-saving end seals, labor-saving efficiency, high scores are extinguished 11 against their own responsibilities and obligations. Even in small details, the "company" has to become the industry leader. In 2004, when we inspected the construction site, we discovered a situation where the installer installed a spray nozzle and then applied a secondary refinish spray to the ceiling. Part of the spray heads (mostly glass balls) were covered with paint. This is very Dangerous things, because the temperature sensing element is covered with paint, will inevitably cause changes in the RTI (response time index), and even more will affect the nozzle delay the fire after the fire to delay the fire. The company’s leaders instructed the technicians to step up the design of a protective cover. On the one hand, it was used to protect the nozzle from scratching the glass balls when installing the nozzle; on the other hand, it was able to protect the nozzle after the installation was completed and was affected by the decoration or secondary decoration. The technicians improved the protective cover during the subsequent technological transformation to facilitate the installation process of the spray head. Record, record batches of glass balls. The principle of “first-in-first-out†is adopted for product in and out of the warehouse. This ensures that the invoice can be found through the product management center invoice. Each nozzle used by the customer, through the product management center, can trace the inspection production record of each nozzle, and can even trace the batch of the nozzle body, the batch number of the glass ball, and the production inspection personnel. This strict management traceability system has also been applied to other company products such as alarm valves, water flow indicators, and pressure switches. This will enable us to check the source of product quality and check the responsibility, and to strengthen the employee's product quality responsibility system. Sense of mission. 2 The alarm valve class production inspection valve body is the core component, part of the entrusted to the qualified supplier for production, the first inspection process before entering the plant is a static pressure seal test, the entire valve body is filled with 24MPa water pressure Requires that there is no leakage after 5 minutes. Some products will be eliminated through a simple process. This is because the valve body has a large casting body, and sometimes it has internal casting defects such as porosity, shrinkage, and inclusion. The inspection process is to ensure that the valve body can guarantee normal working conditions. Then check the dimensions of the valve body. Products that exceed the allowable range will be returned to the supplier as nonconforming products. Only the parts of qualified products can enter the production process. The alarm valve assembly process requires the patience and meticulousness of the production personnel and the skillfulness of the fitters in order to accurately and successfully assemble the valve. Then the alarm valve function test was performed. The valve leakage and deformation tests were first performed. The test of 24 MPa static pressure water does not allow any leakage and deformation, and 100% of all inspections are required. Measure measures, reduce the labor intensity of workers, and improve labor efficiency, carried out a suppression technical transformation program, after several months of design, production, installation, commissioning, put into use. In the actual use process, the operator obviously feels safe, so the quality is guaranteed by the facilities and equipment that require advanced technical means. The last is a functional test. This is a test of the simulation function when the alarm valve is used in the workplace. It is also the most critical one. It requires that the production personnel and the inspector work together to complete the test. The inspectors are responsible for the function of the product. Therefore, every detail cannot be ignored by the inspector. The responsibility is more important than Taishan. This will affect the performance of the product after it is provided to the user, and is an important guarantee for the normal operation of the alarm valve. The entire assembly inspection process has a production inspection record sheet. There will be signatures of the assembly personnel of each alarm valve body (stencil number) as well as the inspection personnel of each process in order to facilitate accountability. Therefore, high quality products are derived from Every employee’s high sense of responsibility and attitude is guaranteed by a reasonable and perfect system. An inspector suggested that the installation rate of the side cover of the deluge valve is low because the outside of the side chamber cover must be connected to the DN15 pipeline. The process requires two pipes to be installed vertically. However, due to the drilling and tapping process, sometimes the process cannot be very difficult. To meet the requirements well affected the installation direction of the pipeline. For this reason, the Ministry of Technology used this item as a small technological transformation project, redesigned an end cap and completely solved the problem, and the employee was commended by the company for his rationalization proposal. In short, the “company†is a member of the socialized large-scale production and has made due contributions to the society in order to protect the lives and property of the people. The Yongji An brand is built on the quality consciousness of the employees of Yongji Security. It is also the result of the hard work of YongJian people with their own sense of responsibility and social responsibility. The company maintains its vitality and exuberant vitality in the fire sprinkler industry. Ten people died in a fire in a sofa workshop in Kunming. At 16:17 on August 10th, a fire broke out in a sofa workshop in Kunming City, killing 10 people and injuring two people. It is understood that the fire building is a three-story brick-concrete residential building, with an area of ​​about 250m2, and is a workshop for processing sofa cushions. The site of the fire was a layer of stored sponge material. The fire caused a layer of indoor items to be completely destroyed. Some of the interior of the second floor was burned. The burned area was about 150m2. The burning material produced a large amount of toxic gas, killing 10 people and injuring 2 people. Among them, 2 of the dead were infants and children, and the rest were migrant workers in the workshop. After receiving the alarm, the Kunming City Fire Brigade dispatched 5 fire engines to the scene to fight the fire. After nearly 1 hour of fighting, the fire was at 17:15.
