　　　　　　 CCTV News:At about 7: 50 pm yesterday (26th), an explosion occurred in a factory in Weishi County, Henan Province, which caused a fire, killing 6 people and injuring 5 others. After the accident, the wounded were sent to the First People’s Hospital of Zhengzhou City, Henan Province for treatment. Three of them were in critical condition and were still being rescued.

　　　　　　 Today (27th) morning, the reporter saw in the natural spice extraction workshop of Xumei Biotechnology Co., Ltd. that the two tempered glass windows in the workshop were all shattered and the tiles on the surrounding walls were also shattered. It is understood that at about 7: 50 last night, a double tank in the workshop exploded, causing a fire.

Shattered tempered glass

　　　　　　 Guo Jianfeng, a member of the investigation team of the 6.26 accident in Weishi County, Henan Province, said: "Up to now, six people have died, and five others are being treated with all their strength."

　　　　　　 According to the hospital, all the five wounded were men, aged between 24 and 35. Two of them have a burn area of about 30%, and their condition is relatively stable at present. The other three people’s burn area is more than 95%, which belongs to extremely severe burns.

　　　　　　 Xia Chengde, director of the Burn Department of the First People’s Hospital of Zhengzhou City, Henan Province: "After admission, we gave these three people tracheotomy, limb reduction (force) surgery, and the other was anti-shock and anti-infection treatment. At present, these three patients are in ICU (rescue) and are still in shock, and their condition is more critical. "

　　　　　　 At present, Zhengzhou First People’s Hospital has invited domestic burn experts to consult three critically ill patients this afternoon. At present, the cause of the explosion accident is under investigation.

　　Nuclear energy, also known as atomic energy, is the energy generated when nuclear fission or fusion occurs, which is widely used in industrial and military fields. Nuclear power is the abbreviation of nuclear power generation, which is the electricity generated by nuclear power generation. Using nuclear energy to generate electricity is conducive to optimizing the national or regional energy structure, improving energy security and economy, and playing an increasingly important role in economic and social development. According to the statistics of the International Atomic Energy Agency (IAEA), as of the end of January 2011, there were 442 nuclear power units in operation in the world, and the operating nuclear power plants were mainly distributed in North America, Asia and Europe, accounting for about 16% of the global power generation. There are 65 nuclear power units under construction, including 30 in China. At present, there are 13 nuclear power units in operation in China, ranking 11th in the world, with an installed capacity of 11.169 million kWh, accounting for 1.16% of China’s total installed power capacity, and the annual power generation is equivalent to 31.72 million tons of coal.

　　First, the working principle of nuclear power plants

　　A nuclear power station is a power station that uses the energy released by nuclear fission or fusion reaction of atoms to produce electric energy. At present, nuclear power plants in commercial operation all use nuclear fission reaction to generate electricity. Nuclear power plants are generally divided into two parts: nuclear islands (including reactor devices) that generate steam by atomic nuclear fission and conventional islands (including turbine-generator systems) that generate electricity by steam. The fuels used in nuclear power plants are generally the chemical elements uranium and plutonium. At present, the main types of nuclear power plants in operation and under construction are PWR, candu nuclear power plant, boiling water reactor, fast reactor and gas-cooled reactor.

　　Pressurized water reactor (PWR) nuclear power plant is a thermal neutron reactor which uses pressurized light water as coolant and moderator, and water does not boil in the reactor, and uses thermal neutrons to cause chain reaction. Daya Bay Nuclear Power Plant, Ling ‘ao Nuclear Power Plant, Qinshan No.1 Nuclear Power Plant, Qinshan No.2 Nuclear Power Plant and Tianwan Nuclear Power Plant in China all belong to this type of reactor. Candu nuclear power plant uses light water as coolant and heavy water as moderator, and the water does not boil in the reactor. It is also a thermal neutron reactor that uses thermal neutrons to cause chain reaction. Qinshan No.3 nuclear power station in China belongs to this type of reactor. Boiling water reactor nuclear power plant uses light water as coolant and moderator, but water boils in the reactor, which uses thermal neutrons to cause chain reaction. Fukushima Daiichi nuclear power plant in Japan belongs to this type of reactor. The fast reactor nuclear power plant is a nuclear reactor in which the thermal energy released by the chain reaction caused by fast neutrons is converted into electrical energy. The nuclear power plant imported from Russia and to be built in Sanming, Fujian Province belongs to this type of reactor. Gas-cooled reactor nuclear power plant is a thermal neutron reactor with gas (carbon dioxide or helium) as coolant, which is caused by thermal neutrons. So far, three types of reactors have been developed, such as natural uranium graphite gas-cooled reactor, improved gas-cooled reactor and high temperature gas-cooled reactor. The Shidaowan nuclear power plant to be built in China belongs to high temperature gas-cooled reactor. The nuclear power plants in operation and under construction in China are mainly pressurized water reactor nuclear power plants.

　　PWR nuclear power plants generally have three loops: primary loop (reactor device), secondary loop (turbine generator system) and tertiary loop (circulating water system). Nuclear fuel burns in a special form in the reactor, generating heat to heat the coolant in the primary circuit. The heated coolant enters the steam generator under the push of the main pump, which heats the water in the secondary circuit and turns it into steam, and then is sent back to the core by the main pump for reheating. This continuous cycle is called a loop. Steam enters the steam turbine through the pipeline, which drives the turbine generator to do work and generate electricity, then enters the condenser, and is cooled into water and returned to the steam generator. This steam-water cycle process is called the secondary loop. The third loop uses seawater or fresh water, and its function is to cool the steam in the second loop in the condenser to change it back into condensed water.

　　In order to ensure the safety of nuclear power plant, many safety facilities are also considered in the design, including: automatic shutdown system, reactor overpressure protection system, emergency core boron injection system, emergency core cooling system, emergency water supply system, radioactive material containment system and its supporting emergency power supply and cooling ventilation system. On March 11th, 2011, the safety system of Fukushima nuclear power plant in Japan performed related functions, such as automatic shutdown and emergency diesel generator start-up. However, due to the magnitude 9 earthquake and tsunami, the related systems were out of power and lost the final heat sink due to flooding.

　　According to China’s nuclear safety regulations and the recommendations of the International Atomic Energy Agency, the principle of "defense in depth" is strictly implemented in the design, construction and operation of nuclear power plants in China, and multi-level overlapping protection is provided from equipment and measures to ensure that radioactive materials can be effectively contained without leakage. "Defense in Depth" includes the following five lines of defense: careful design and construction to ensure excellent equipment and safety training of nuclear power plants; Strengthen operation management and supervision, and eliminate faults in time; Design and provide multi-level safety system and protection system to prevent equipment failure and human error from causing accidents; Activate the safety system of nuclear power plants, strengthen the management of power plants in accidents, and prevent accidents from expanding; Start the emergency response plan inside and outside the factory, and strive to reduce the impact of the accident on the surrounding residents.

　　Two major nuclear accidents and experience feedback

? 　Due to the complexity of the nuclear power plant system and the limitation of human understanding, there were two major nuclear accidents before the Fukushima nuclear accident. The accident at Three Mile Island in the United States on March 28th, 1979 had little impact on the environment. The Chernobyl accident on April 26, 1986 really made people realize the potential threat of nuclear power plants. In the accident, 237 occupational workers were exposed to clinically effective overdose radiation, of which 134 showed symptoms of acute radiation and 28 died within 3 months. From 1986 to 1987, the average radiation dose of 200,000 people who participated in accident treatment was about 100 millisieverts, of which about 10% people received 250 millisieverts and a few people received more than 500 millisieverts. After the accident, about 10% of the 116,000 residents evacuated from the restricted area with a radius of 30 kilometers received more than 50 millisieverts, and less than 5% received more than 100 millisieverts. Short-term exposure of humans to radiation doses below 100 millisieverts is basically harmless. The investigation shows that the fundamental causes of Chernobyl accident are design defects (positive power coefficient, no containment, etc.) and human errors (serious violation of regulations). The Chernobyl nuclear accident is by far the most serious one (the Fukushima nuclear accident cannot be accurately evaluated at present due to the lack of specific data).

　　Through the summary and reflection of nuclear accidents, many new safety measures and safety concepts have been developed. After the Chernobyl accident, international nuclear safety group of IAEA put forward the concept of nuclear safety culture, and published the report "Safety Culture" in 1991, which was widely accepted worldwide. At the same time, nuclear operators in the world realize that any nuclear accident will have an impact on other nuclear power plants. Therefore, it is necessary to strengthen exchanges and cooperation among nuclear operating units, promote effective experience feedback, and establish a nuclear safety culture to prevent nuclear accidents. In May 1989, 144 nuclear operators around the world signed the Charter of the World Association of Nuclear Operators (WANO) in Moscow, aiming at improving the safety and reliability of nuclear power plants around the world.

　　Third, the new generation of nuclear power technology and its prospect

　　After nearly 60 years of development, nuclear power has formed a complete set of systematic and complete theoretical system and accumulated a lot of operating experience. The newly designed nuclear power units are divided into two directions: one is to increase the configuration of special safety facilities to enhance the safety of the units, represented by EPR nuclear power units in France and VVER nuclear power units in Russia; Second, a large number of passive special safety facilities are used to enhance the safety of the unit, represented by the AP1000 nuclear power unit in the United States. French EPR adopts the design concept of "plus", that is, to increase redundancy to improve safety, and the safety system is increased from two series to four series, which also increases the complexity of the safety system and takes corresponding measures to prevent and alleviate serious accidents. The American AP1000 safety system adopts the "passive" design concept, which better achieves the "simplified" design principle. The safety system uses the natural characteristics of materials (gravity, natural circulation, energy of compressed gas, etc.), and does not need pumps, AC power supplies and corresponding support systems such as ventilation and cooling water, which greatly simplifies the safety system and reduces human errors. The design concept of VVER nuclear power unit in Russia is similar to that of EPR in France.

　　The accident of Fukushima nuclear power plant in Japan has once again aroused people’s concern about the safety risks of nuclear power, which will promote people’s continuous exploration of new technologies, with the aim of making nuclear energy safer, cleaner and more efficient.

　　At present, what are the research results of highly pathogenic avian influenza?

　　Since the mid-1990s, China has done a lot of work on the epidemiology, diagnosis, immune control and basic research of avian influenza, and obtained many research results. The diagnosis technology of avian influenza has been established: ① agar diffusion (AGP) diagnosis technology. ② subtype typing technology of avian influenza virus. ③ Molecular diagnosis and detection technology of avian influenza virus. Avian influenza vaccine development: An inactivated vaccine of H5 subtype avian influenza has been developed, which can be used for emergency immunization of H5 subtype highly pathogenic avian influenza. The live carrier vaccine of H5N1 subtype avian influenza recombinant fowlpox virus has also entered the stage of environmental release and safety evaluation.

　　How long will it take to confirm the pathogen? Do what experiment?

　　Highly pathogenic avian influenza must be diagnosed by virus isolation and identification. It usually takes at least 3~5 days for virus isolation and subtype identification. The pathogenicity of the virus must be finally determined by artificial intravenous inoculation of non-specific pathogen chickens (SPF chickens).

　　What is the standard for diagnosing highly pathogenic avian influenza stipulated in the technical specification for prevention and control of highly pathogenic avian influenza issued by the Ministry of Agriculture? According to the Notice of the Ministry of Agriculture on Printing and Distributing Seven Technical Specifications for Prevention and Control of Highly Pathogenic Avian Influenza (Nongbanmu [2002] No.74), highly pathogenic avian influenza can be confirmed to have occurred under the following circumstances: ① There are typical clinical symptoms and pathological changes, acute onset and high mortality, and Newcastle disease and toxic diseases can be excluded, and serological tests are positive. ② Avian influenza serotypes H5 and H7 were seropositive in the poultry that were not immunized. ③ Avian influenza virus strains of H5 and H7 subtypes or other subtypes were isolated from poultry flocks.

　　According to the virulence, avian influenza is divided into several categories, how to identify it?

　　Influenza viruses are divided into highly pathogenic avian influenza virus (HP avian influenza virus), low pathogenic avian influenza virus (LP avian influenza virus) and non-pathogenic avian influenza virus (NP avian influenza virus) according to their pathogenicity. In view of the importance of HP avian influenza virus, the relevant identification standards and procedures are introduced as follows:

　　The World Organization for Animal Health classifies highly pathogenic avian influenza viruses as follows:

　　(1) Eight susceptible chickens aged 4-8 weeks were inoculated with 02 ml of 1∶10 diluted allantoic fluid infected with influenza virus by intravenous injection, which could cause 6-7 or 8 chickens to die within 10 days after inoculation. These influenza viruses should be highly pathogenic.

　　(2) The isolate can kill 1~5 chickens, but the virus is not H5 or H7 subtype, so the following experiments should be carried out: Inoculate the virus on the cell culture, and observe whether it causes cell pathological changes or forms plaque when trypsin is lacking. If the virus cannot grow on cells, the isolate should be considered as a non-highly pathogenic avian influenza virus.

　　(3) When all H5 and H7 strains with low pathogenicity and other viruses can grow on cells lacking trypsin, the amino acid sequence of peptide chain related to hemagglutinin should be analyzed. If the analysis results are similar to other highly pathogenic avian influenza viruses, this tested isolate should be considered as highly pathogenic avian influenza virus.

　　How to collect and separate the samples of the pathogen after the occurrence of avian influenza?

　　The diagnosis depends largely on the quality of the sample, the storage and transportation process of the sample before laboratory treatment. Samples of respiratory viruses used for cell culture, chicken embryo inoculation and direct detection of virus antigens or nucleic acids should be collected 3 days after the onset of flu symptoms. Avian influenza is mainly infected by respiratory tract and digestive tract. Therefore, the samples collected from the upper respiratory tract of mammals and birds are suitable for the identification and diagnosis of influenza virus. There are three types of upper respiratory tract swabs: nasal cotton swabs, throat cotton swabs and tracheal cotton swabs. Slaughtered or dead mammals should collect samples in the lower respiratory tract, which are divided into three types: tracheal cotton swab, bronchial cotton swab and lung tissue. Avian samples should be collected in the respiratory tract and most of the digestive tract. The virus samples collected include cloacal cotton swabs and feces, among which cloacal cotton swabs can be collected from live chickens or slaughtered chickens. Collecting feces samples from chicken coops or the environment is a common sampling method, but it has the disadvantage of not being able to determine the exact source of samples. If it is suspected that dead birds contain highly pathogenic avian influenza virus, representative internal organs such as brain, spleen, heart and lung should also be collected.

　　If you want to detect the virus directly by immunofluorescence staining of infected cells, then the collected disease materials should be placed in an ice bath and the samples should be processed within 1~2 hours. Samples used for virus isolation should be frozen in the refrigerator immediately after sampling, and inoculated into sensitive cells or chicken embryos as early as possible. If the sample cannot be processed within 48~72 hours, it should be frozen at -70℃ or below. If the test tube containing the sample is not sealed, or the plastic bag containing the sample is not tightly sealed, the sample cannot be transported or stored in dry ice. Because once the dry ice comes into contact with the diseased sample, it can quickly inactivate the influenza virus that may exist in it.

　　The collected samples should be placed in a suitable transport buffer to ensure the isolation of the virus. At present, there are some transport buffers suitable for different virus samples, such as Hanks balanced salt solution, cell culture medium, phosphate buffer, tryptone-phosphate broth, calf beef soup and sucrose phosphate buffer, etc. In these transport buffers, 0.5% ~ 1% protein, such as bovine serum albumin and gelatin, should be added, and antibiotics should be added to prevent the growth of bacteria.

　　How to collect and transport pathological samples?

　　Pathological samples should generally be taken from dead or live birds in the early stage of infection or acute stage of onset. Dead birds collected tissue samples such as trachea, lung, liver, kidney, spleen and cloaca. Live birds should be smeared with sterilized cotton swabs of different sizes on throat, trachea or cloaca. Cotton swabs with secretions should be put into broth containing 1 000 international units of penicillin, 2 000 micrograms of streptomycin and pH 72 ~ 76 per ml. When there is no broth, Hanks solution or 25%~50% glycerol saline can be used. The concentration of antibiotics used in feces and cloaca cotton swabs should be increased.

　　Transportation and storage of samples: if the collected samples are inspected within 48 hours, they can be stored at 4℃; Otherwise, it should be stored at low temperature (-70℃ is the best).

　　What are the diagnostic methods and procedures for highly pathogenic avian influenza?

　　(1) Epidemiology Avian influenza virus has a wide range of hosts, such as chickens, turkeys, ducks, geese, quails and pheasants, and wild birds, waterfowl and seabirds. Among them, chickens and turkeys are the most harmful after being infected with avian influenza virus, and more viruses are isolated from ducks than other poultry. Birds of all ages can be infected.

　　Avian influenza virus is mainly transmitted through direct contact and indirect contact between infected birds (including equipment in contact with infected birds). In addition, poisonous birds or waterfowl often become the source of infection, causing a large number of diseases and deaths of poultry.

　　(2) The incubation period of clinical symptoms of avian influenza varies from several hours to three days. The incubation period depends on the virulence and dose of the infected virus, the route of infection, the species of infected birds and the state of the birds. Acute infection of avian influenza has no specific clinical symptoms. In a short time, loss of appetite, sudden rise of body temperature, respiratory symptoms, diarrhea and neurological symptoms can be seen. With a large number of deaths.

　　(3) Pathological changes The pathological changes of avian influenza vary with the virulence of the infected strain, the duration of the disease and the species of birds. The main manifestations are head swelling, fleshy beard, crown bleeding, subcutaneous bleeding and edema of legs and toes, glandular stomach nipple bleeding and salpingitis.

　　(4) Etiological diagnosis-virus isolation needs to be completed by the national laboratory.

　　(5) Serodiagnosis At present, the methods used for avian influenza detection include avian influenza virus isolation, agar diffusion (AGP) test, hemagglutination inhibition (HI) test, neuraminidase inhibition (NI) test, enzyme-linked immunosorbent assay (ELISA), virus neutralization test (SN), reverse transcription polymerase chain reaction (RT-PCR), immunofluorescence technology (IF) and nucleic acid probe technology.

　　Avian influenza virus hemagglutinin typing antigen and standard typing serum were provided by Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, and operated according to the instructions.

　　In a word, the diagnosis of avian influenza, the isolation and identification of laboratory viruses and the pathogenicity test all take a long time and cost a lot. Only a few laboratories can carry out this inspection, and they can’t make a diagnosis within a short time (48 hours) after receiving the inspection samples, and the diagnosis lags behind the requirements of taking measures on the spot. The faster and earlier the diagnosis of avian influenza is made, the smaller the loss will be. When bird flu is suspected, it is very important to report the epidemic situation in time so as to obtain timely diagnosis from relevant experts.

　　How to make a differential diagnosis of avian influenza?

　　Because the epidemic characteristics, symptoms and pathological changes caused by avian influenza infection are similar to some infectious diseases of poultry, it is necessary to make differential diagnosis in time, such as Newcastle disease, infectious bronchitis, infectious laryngotracheitis, infectious rhinitis, mycoplasma disease, chlamydia disease, egg drop syndrome, etc. Especially the mixed infection or secondary infection of some diseases makes the condition more complicated, which makes diagnosis difficult or easy to be misdiagnosed. Therefore, the differential diagnosis is very important.

　　The first is the differential diagnosis with Newcastle disease. The epidemic characteristics, symptoms and pathological changes of avian influenza are very similar to those of Newcastle disease in chickens. Generally speaking, the incubation period and course of highly pathogenic avian influenza are shorter than those of Newcastle disease in China at present. The symptoms such as dyspnea, hydrops in crop and mouth, cooing when dyspnea, typical neurological symptoms and conventional typical pathological changes are all more obvious and characteristic than avian influenza. In addition, the emergency immune effect of Newcastle disease on the spot is all related to avian influenza. However, some of them are not obviously different. The accurate differential diagnosis of the two diseases can only rely on laboratory diagnosis. The simplest and most practical methods are virus isolation and hemagglutination inhibition test (HI). Newcastle disease antiserum can not inhibit the hemagglutination of avian influenza virus, and vice versa.

　　According to the comprehensive analysis of epidemic characteristics, symptoms, pathological autopsy and laboratory examination (etiology, serology), avian influenza can be distinguished from other epidemics. Similarly, secondary or complicated bacterial or viral diseases can be determined by pathogen isolation and some detection methods.

　　Excerpted from "Questions and Answers on Prevention and Control of Highly Pathogenic Avian Influenza" by China Agricultural Publishing House.

　　"In fact, the villagers’ awareness of fire prevention has improved a lot now, and the real fire fighting and rescue tasks at work have been reduced to a certain extent. We have begun to closely integrate fire fighting forces with rural revitalization. I hope ‘ Give full play to advantages and highlight characteristics ’ , to embark on a rural revitalization with unique characteristics of Miao and Dong villages ‘ Safe road ’ 。” In the Leishan County Fire Rescue Brigade, Luo Jie, the instructor of the brigade, is introducing the situation of the team to reporters.

　　Leishan County is located in the southwest of Qiandongnan Miao and Dong Autonomous Prefecture, Guizhou Province, with dense forests and winding waters. It is dominated by ethnic minorities such as Miao and Dong, and has the largest Miao village in the world, Xijiang Miao Village. In recent years, Xijiang Qianhu Miao Village Scenic Area has become a tourist attraction, and the county has vigorously implemented "global tourism" to fully activate the "new kinetic energy" of rural revitalization. However, the mountain features, the housing structure of Miao village and the security risks brought by "tourism fever" all bring challenges to the local grass-roots fire protection work.

　　How to get through the "last mile" of fire safety management based on local characteristics; How to give full play to the firefighting power, practice "people’s firefighting for the people", and realize the effective connection between consolidating and expanding the achievements of poverty alleviation and rural revitalization? The Leishan County Fire Rescue Brigade combines the main responsibility and main business, thinks ahead and takes the initiative to explore and form the Xijiang model of grassroots firefighting work, and escorts rural revitalization with safety.

　　Enrich strength

　　Take the lead in realizing full coverage of full-time fire brigade of township government.

　　Records of store fire inspection during flood control in Xijiang Town, fire safety checklist for farmers during this winter and next spring, and "one household for one file" for fire safety in Xijiang Miao Village Scenic Area … In the office of Xijiang Town Government full-time fire brigade, piles of forms and documents record the fire safety inspection work of the brigade in detail.

　　"We will carry out fire safety inspections on 21 administrative villages in Xijiang Town every month and at important time nodes, and check the water level of drinking water pools and special fire-fighting pools in scenic spots, and implement the system of twice-daily inspection and twice-reporting." Li Jian, vice captain of the team, said that the information collection and archiving of 571 business premises and 1,270 farmers in Xijiang Scenic Area have been completed.

　　In order to improve the county’s fire prevention and control ability, Leishan County forced the grassroots responsibility, promoted the establishment of fire safety committees and fire workstations at the county and township levels, established a three-level fire safety guarantee system at the county, township (town) and village levels, and invested 3.5 million yuan to complete the construction of seven township full-time fire brigades, taking the lead in realizing full coverage of township government full-time fire brigades in the whole state, and completed the construction of 125 volunteer fire brigades in more than 50 wooden contiguous villages, further consolidating the foundation of rural fire prevention and control.

　　In addition, in view of the large flow of people and limited fire prevention and control ability in Xijiang Scenic Area, Leishan County established a leading group for tourism safety improvement in Xijiang Scenic Area, which was composed of 7 party and government leaders and 45 industry department heads. The county fire rescue brigade took the initiative to draw the county party Committee and the county government to combine the actual situation of the scenic spot. The Measures for Fire Safety Management (Trial) of Xijiang Qianhu Miao Village Scenic Spot in Leishan County and the Notice on Further Defining the Responsibilities of Fire Safety Prevention in Xijiang Scenic Spot and Strengthening the Responsibility Investigation have been issued successively to refine the responsibilities of fire safety functions of scenic spots at all levels and departments, and eight fire micro-stations and two fire observation posts, namely, the central observation platform and Baiyan, have been set up in the scenic spot.

　　The reporter came to the central observation deck post. On the observation deck, the Xijiang scenic spot was unobstructed. The post is also specially equipped with telescopes and thermal imaging probes. If a place "has a cigarette and a little spark", the duty officer can accurately capture and respond quickly.

　　There are 1,580 houses in Xijiang Qianhu Miao Village, with a permanent population of 1,446 households with more than 6,100 people. The full-time fire brigade of Xijiang Town Government divides Xijiang Scenic Area into four areas: Nangui, Yangpai, Dongyin and Pingzhai, and comprehensively strengthens the investigation of fire hazards in the scenic area through "all-in-one, all-in-one and active service".

　　"Although the business in scenic spots has brought economic income to our town, if the safety work is not done properly, such development is ‘ Walk with a limp ’ Once something goes wrong, the consequences are unimaginable. " Li Jian said that the barbecue street in the scenic spot is a long-standing problem of fire safety, and some merchants lack certain safety awareness in the use of gas, which requires repeated inspections and key education.

　　In the first half of this year, the Leishan County Fire Rescue Brigade organized fire rescue personnel and full-time fire brigade members to carry out actions such as no smoking in scenic spots, management of flammable and combustible decorations, management of restaurants and fire exits, etc. A total of 1,184 business premises were investigated, 78 decorative places of flammable and combustible materials were completely removed by compulsory measures, 84 restaurants and restaurants were urged to install gas alarms, and 186 illegal acts of occupying fire exits were investigated, 21 trailers and 152 motor vehicles were detained.

　　Strengthen security

　　Constructing a three-dimensional fire prevention and control system

　　Mountainous area is the biggest feature of Guizhou. Xijiang scenic spot is located in the slope zone of the transition between Hunan and Guangxi hilly basins in Yunnan-Guizhou Plateau, with rolling mountains.

　　"If there is a fire, large vehicles and equipment are inconvenient to enter. On the one hand, building a reservoir on the mountain can facilitate the villagers’ domestic water use, and on the other hand, when a fire breaks out, the reservoir can become a source of fire water nearby." Luo Jie said.

　　Safety is the premise of development. In order to do a good job in rural fire protection grass-roots construction, Leishan County Fire Rescue Brigade focuses on the essential fire safety transformation such as kitchen reform, water reform and electricity reform in wooden contiguous villages, and strengthens the management of fire safety sources.

　　"Volunteer fire brigade, fire pool and motor pump are the three magic weapons to realize fire disposal, and water shortage is fatal." Fei Teng, the fire supervisor of the brigade, found that the fire water in the scenic spot could not meet the actual demand during the in-depth investigation of the fire infrastructure in Xijiang scenic spot, so the brigade reported to the county government in combination with the "water reform" project and put forward renovation suggestions. Subsequently, the county invested funds to improve the construction of 12 high-level fire pools, three circular fire pipe networks, 108 fire hydrants and supporting facilities and equipment with a total of 1,500 cubic meters.

　　Xijiang Scenic Area also focuses on making it clear that the public fire-fighting pipe network needs to be equipped with one fire hydrant every 40 meters, and each house can be effectively covered by two fire hydrants. All the business premises that are rebuilt by villagers’ self-built houses are equipped with simple automatic fire alarm systems, sprinkler systems and hose reels, and the technical standards such as safety exits, evacuation routes, allocation of fire-fighting equipment, and safe use of fire and electricity are made clear, thus solving the dilemma that the all-wood structure buildings in the scenic area cannot be implemented with reference to national and industrial standards.

　　In order to solve the problem that the traditional electricity reform can’t effectively monitor people’s unsafe electricity use, which leads to a high number of electrical fires, Xijiang Scenic Area has installed more than 1,100 arc-extinguishing electrical fire protector terminals and 8 water level online monitors, realizing 4,680 times of early warning and disposal, realizing a new pattern of real-time online monitoring of electricity safety, intelligent analysis and judgment of rural electricity risk laws, accurate assistance in fire hazard elimination, and standardized fire safety management with data cages.

　　It is necessary to take physical defense and technical defense measures, but also to improve civil air defense capabilities. "Leishan is a gathering place for ethnic minorities, and the villagers here are very talkative ’ Love ‘ Heavy customs. " Luo Jie said, Xijiang Scenic Area should be governed by the whole people, implement the "ten-household joint defense", integrate the traditional fire management methods of Miao village with the traditional discussion, formulate and issue village rules and regulations with public binding force, and promote fire inspection, shouting for the village, publicity and training, monitoring of key personnel, greeting for weddings and funerals and other measures to be effectively implemented.

　　Active integration

　　Actively carry out rural revitalization and assistance work.

　　"Secretary Xiao Gong is here!" On August 2nd, Grandma Li Mingzhen, a villager from 12 groups of lamb chops in Xijiang Village, stood at the door of her house early in the morning. Today is the day when Gong Enpu, the first secretary of Guizhou Provincial Fire and Rescue Corps stationed in Xijiang Village, paid a regular visit. At the sight of Gong Enpu, the old man Li Mingzhen held his hand tightly and took it to the house.

　　"Li Popo, I think the high temperature has continued in recent days, and I bought you an electric fan. Don’t blow on the fan when you are old." Gong Enpu told Li Nainai while installing an electric fan.

　　Since he became the resident secretary of Xijiang Village in 2021, Gong Enpu has cooperated with Guizhou Provincial Fire Rescue Corps and Leizhou County Fire Rescue Brigade to actively carry out rural revitalization and resident assistance.

　　Guided by the idea that the Corps adheres to the combination of blood transfusion and hematopoiesis, and the combination of poverty alleviation and intellectual support, the county fire rescue brigade fully combines the characteristics and reality of ethnic minorities living in its jurisdiction, highly integrates fire rescue work with strategic policies such as "national unity", "poverty alleviation" and "rural revitalization", and works hard on the issues that the masses are most worried about and looking forward to, and makes practical moves.

　　The county fire rescue brigade brought the poverty alleviation work into the agenda of the party Committee, established the precise poverty alleviation strategy of "fixed point, fixed person and fixed household" and "promoting rural fire safety", implemented the "frontline work law of the party Committee", set up a 6-member party member vanguard team to carry out police pre-help at important nodes, and established and improved the fire protection work system of the two village committees.

　　In the meantime, the relevant personnel of the Party Committee of the Corps and the detachment have conducted in-depth research on helping villages for 13 times to find out in detail the difficulties existing in the current rural revitalization work, and awarded 600,000 yuan of "fire-fighting inspirational scholarships" to 32 poor students in 6 helping villages. The Corps has invested a total of 6.078 million yuan to build a fire-fighting industrial road, a fire-fighting bridge and a miniature fire station for the villages, and donated more than 50 children of poor households in the villages to actively develop fish and black rice fields.

　　"A year’s time is not long, but I have been fully integrated here, and I have gradually moved from a village ‘ Outsider ’ It became ’ Family ’ 。” Gong Enpu told reporters that whether it is the first-line rescue or the current assistance in the village, the villagers’ affairs are his biggest thing, and he can be the guardian of the safe development of his hometown without regrets.
