The so-called "production process fire prevention" refers to the fire risk existing in the operation unit, process unit, material processing unit, and the equipment and equipment associated with it according to the specific production process of various products, and proposes corresponding fire prevention. Technical countermeasures to eliminate and avoid a fire prevention technology. Production process fire prevention and production technology are inseparable. It runs through the whole process of production and develops with the development of science and technology and production technology. The practical significance of fire prevention in production process Industrial enterprises, the magnitude of their fire hazard depends mainly on the fire hazard present in the production process. Because of the production of a product, what raw materials are used, how much temperature and pressure are required, what equipment and additives are used are specific. For example, phosphorus trichloride can only be produced by using chlorine gas and yellow phosphorus as raw materials. Ammonia can be synthesized only by hydrogen and nitrogen, and cotton yarn can only be spun with cotton. Here, raw materials such as yellow phosphorus, chlorine gas, hydrogen gas and cotton are all flammable dangerous goods, and the fire hazard in the production process of products such as phosphorus trichloride, ammonia and cotton yarn is determined. For example, the synthesis of ammonia has three methods of high pressure, medium pressure and low pressure, and can be synthesized only under a certain temperature and pressure; high pressure polyethylene needs to be polymerized at a temperature of 1000 to 3000 atmospheres and a temperature of 50 to 300 °C. Therefore, the equipment selected must have high temperature and high pressure conditions. At the same time, due to the presence of high temperature and high pressure, the spontaneous combustion point of nitrogen, hydrogen mixture and ethylene will decrease, and the explosion limit will be widened, thus increasing the fire risk. In other words, the fire hazard of industrial enterprises depends on the characteristics of raw materials, semi-finished products, finished products and production process conditions. Therefore, the fire prevention measures taken by a factory must be determined according to the production process of the factory. The fire prevention work grasped the focus of the production process and seized the initiative of fire prevention. In short, “production process fire protection†is of great significance, as follows: First, the fire protection audit of building design needs to know that the fire hazard category of the production process of industrial enterprises is determined by the production process. It is difficult to grasp the fire hazard of the plant or workshop or section without mastering the production process, and it is impossible to make reasonable claims based on the fire hazard category. Fire safety review comments. Second, the fire cause investigation needs to master the production process Fire investigation personnel do not grasp the production process, it is not easy to find out the cause of the fire, and most of the fires of industrial enterprises occur in the production site. Third, the factory fire inspection needs to understand the production process. Do not grasp the characteristics of the production process of the factory. When conducting fire prevention supervision and inspection, it is difficult to accurately identify the fire hazard and propose reasonable rectification measures. 4. Electrical fire prevention personnel need to be familiar with the production process. In the selection of explosion-proof electrical equipment, the determination of the location and scope of the fire and explosion hazard, and the determination of anti-static and lightning protection measures, it is necessary to carry out on the basis of familiarity with the production process. V. Dangerous goods fire prevention supervision and management needs to master the production process. Fire prevention supervisors can only correctly implement fire prevention supervision on the production of dangerous goods on the basis of mastering the production process; master the production process of dangerous goods, store dangerous goods, Fire prevention supervision of transportation and operation is very beneficial. Main content of production process fire prevention research Each industrial product has its own specific production process, and some products can be produced by a variety of processes. It is difficult to master various production processes at the same time. Therefore, in practice, the production process is summarized as follows: First, it has the characteristics of common physical changes, and second, it has the characteristics of common chemical reactions. Third, the various jobs that change the shape, size, properties or surface state of raw materials, blanks or semi-finished products to meet the specified requirements are collectively referred to as processing. In this way, in addition to the maintenance of the equipment, accessories and equipment used in each production process, it constitutes the main content of the fire prevention research of the production process, namely, chemical unit operation fire prevention, chemical unit process fire prevention, processing process fire prevention, equipment fire prevention, fire safety attachment, Production process equipment fire prevention, equipment maintenance and fire protection. Strengthen the scientific research and system construction of production process fire prevention First, we must strengthen the research and training of production process fire prevention. All localities should carry out business research on production process fire prevention, understand and master the production process of the areas under their jurisdiction, and propose improvement measures for fire prevention of production processes according to actual conditions. All colleges and universities' safety engineering majors should offer a "production process fire prevention" course and teach as a main course. The enterprise shall provide technical training for fire prevention personnel, construction personnel and dangerous goods management personnel to carry out production process fire prevention. Second, strengthen the system construction of fire prevention of production technology Fire supervision work is the statutory duty of the public security organs, but there is no legal provision for how to conduct fire prevention supervision from the production process. Therefore, it is recommended that relevant departments should prepare fire prevention codes including production processes at an early stage; when conducting fire safety audits for building designs, the production processes should also be included; when conducting fire, construction, fire investigation and dangerous goods management personnel, The “production process fire protection†should be included.
