How is preventive disinfection in schools disinfected?

This standard is formulated to standardize preventive disinfection in earthquake-stricken areas, effectively prevent infectious diseases, effectively protect the health of victims, clearly distinguish preventive disinfection from epidemic disinfection, prevent excessive disinfection and abuse of disinfectants, and prevent the omission of important objects and places such as drinking water, public places, kindergartens, schools and medical units. , to ensure that in an emergency, a limited number of disinfectants are used for scientific disinfection in the early post-disaster period, and to ensure the disinfection effect. Due to the particularity of earthquake disasters, emergency preventive disinfection should be carried out within the first two weeks of disaster relief, that is, the emergency rescue and disaster relief stage and the initial stage of temporary resettlement. Therefore, the main technical contents of this standard stipulate the principles, objects, methods and technical requirements, quality control requirements and effect evaluation requirements of preventive disinfection during the post-disaster rescue stage and temporary resettlement period in earthquake-stricken areas. If an outbreak of infectious diseases has occurred in the disaster area, it should be regulated by General Rules for Disinfection of Focal Areas (GB 19 193). The main contents of this standard are divided into 10 chapter and appendix. The third chapter explains the terms and nouns used in the standard, such as disinfection, preventive disinfection, ruins, quick-drying hand disinfectants, public goods, chlorine sterilizers and so on. The fourth chapter stipulates the principle of preventive disinfection. Preventive disinfection should be targeted, and the local disease prevention and control institutions should make risk assessment according to the epidemic types and seasonal characteristics of local infectious diseases, and then put forward preventive disinfection schemes. Chapter V specifies the objects of preventive disinfection. Including drinking water used by people in disaster areas and drinking water supplied by other temporary water supply facilities and equipment; Public dining utensils; Vehicles, tools and manpower for transporting the remains of the wounded and victims; Key environment and places; Other environments, places and objects determined by professionals after on-site investigation. Chapter VI specifies places or articles that do not need preventive disinfection. The damage of earthquake to the environment is physical damage, not harmful microorganisms. Therefore, the disaster area is not an epidemic area. Environments and articles that are not in close contact with people's lives do not need to be disinfected, just keep them clean. Therefore, specifying the environment and articles that do not need disinfection can avoid excessive disinfection, save a lot of manpower and material resources, and avoid environmental pollution caused by chemical disinfectants. Chapter 7 specifies the time and frequency of preventive disinfection. Under normal circumstances, preventive disinfection can be carried out once a day in key environments and places. Drinking water needs to be continuously supplied, so it needs to be disinfected before leaving the factory or before supplying water. After the disaster relief work is completed, the emergency preventive disinfection work can be ended, but industries and units that need daily preventive disinfection such as drinking water, hospitals, restaurants and public places shall be implemented in accordance with relevant regulations. Chapter 8 specifies the technical requirements and methods of preventive disinfection. Different objects need to use appropriate disinfectants and disinfection methods to achieve the best disinfection effect. For pathogens targeted by preventive disinfection, only low-medium-effect to high-efficiency disinfectants can be used to achieve the purpose of disinfection, and no disinfectants are needed. This standard selects chlorine-containing disinfectants as disinfectants on the surface of environment and general objects. These disinfectants are widely used in China, easy to obtain, have little impact on the environment and are basically pollution-free. The dosage form of disinfectant is also convenient for transportation and storage, and it is convenient for measuring and detecting the content of effective components when used. Chapter 9 stipulates the quality control of disinfection process. In order to achieve the expected disinfection effect, the disinfection process should be controlled. First of all, we should ensure the quality of the disinfectant used, second, we should use the correct concentration, and third, the disinfectant should be used in the right way for the right object. Chapter 10 stipulates the evaluation of disinfection effect. If necessary and conditions permit, the disease control institutions can evaluate the preventive disinfection effect according to the inspection methods specified in this standard.
