ABSTRACT
Three technical specifications for centralized treatment engineering of medical waste, which were issued in 2006, have played significant roles in guiding and standardizing the construction and operation of centralized treatment engineering of medical waste in over ten years period. However, with development of industry and upgrading of technologies, especially after the coronavirus disease 2019 (COVID-19) epidemic, the medical waste disposal industry faces new opportunities and challenges, and the construction and operation of the centralized treatment engineering of medical waste needs some adjustments. Under such circumstances, revised three technical specifications were issued and implemented in April 2021. Based on the review of the implementation situations of the technical specifications and the development status of the industry, this study analyzed the necessity of the revision of the technical specifications, and explained the revision ideas of the three technical specifications in terms of construction scale, disinfection treatment technical requirements, pollution control technical requirements and disinfection effect detection frequency. Moreover, to promote the implementation of the revised specifications, suggestions were put forward on clarifying the application scenarios, the technical positioning and the legal effect of the specifications. This study can provide a reference for the construction and operation of medical waste disinfection centralized treatment project in the new era. © 2022, Science Press. All right reserved.
ABSTRACT
The central air conditioning ventilation system plays an important role in the air circulation of buildings such as centralized isolation medical observation points and general public buildings. In order to meet the requirements of COVID-19 epidemic prevention and control, Beijing Preventive Medicine Association organized Beijing CDC and other professional institutes to write up the group standard entitled "Technical specification for health risk investigation of central air conditioning ventilation system during the COVID-19 epidemic (T/BPMA 0006-2020)" . According to the particularity of central air conditioning ventilation system risk control during the outbreak of similar respiratory infectious diseases, based on current laws and regulations and the principle of scientific, practical, consistency and normative, 8 key points of risk investigations were summarized, which were the location of fresh air outlet, air conditioning mode, air return mode, air system, air distribution, fresh air volume, exhaust and air conditioner components. The contents, process, method, data analysis and conclusion of the investigation implementation were also defined and unified. It could standardize and guide institutions such as disease control and health supervision to carry out relevant risk managements, and provided solutions and technical supports for such major public health emergencies in city operations.
