修改了主页的Our project design took safety into account and ultimately chose E. coli Nissle 1917 as our chassis, which was included in the white list and classified as Biosafety Level 1 (BSL-1).文本

修改了主页的d)Laboratory Accident Handling: Accidents that occur during the operation of experimental members, such as needle punctures and cuts, skin contamination, infectious specimens and body surfaces and inside the mouth, nose, and eyes, clothing contamination, contamination of the test bench, etc., are all considered safety accidents. Emergency treatment should be carried out immediately depending on the type of accident and other situations. At the same time of emergency treatment, it is necessary to report to the instructor and record the specific location and degree of the accident and injury in detail. Medical personnel will evaluate whether preventive treatment is needed.文本

修改了主页的c)For accidents, measures including emergency assistance or professional health treatment should be provided to cope with emergencies.文本

修改了主页的In order to avoid and handle accidents caused by unsafe operations, the following principles must be strictly implemented:文本

  According to the "Regulations on the Management of Medical Waste" of the State Council and the "Measures for the Management of Medical Waste in Medical and Health Institutions" of the former Ministry of Health, we manage laboratory waste from the following aspects: ① Designate a dedicated person in the laboratory to be responsible for and coordinate the management of various types of waste; ② Establish waste classification, isolation, packaging, transportation, storage, and disposal procedures in the laboratory; ③ Members of the Experimental Group should correctly dispose of waste to their respective garbage bins, and all solutions and plates should be marked; ④ Strictly follow the waste disposal system and procedures, and have processing records.
  We also have a special waste treatment process for bacteria and other microorganisms, as shown in the figure:文本

The building where the laboratory is located has emergency passages, fire exits, fire equipment, and emergency lighting devices; and our colleagues in the Experimental Group also remember how to quickly escape from the scene when any safety accident occurs to ensure their own safety;There is also a first aid medicine storage area in the corridor for easy use when necessary.文本

Personal protective equipment cannot reduce the concentration of harmful substances in the workplace, nor can it eliminate the harmful substances present in the workplace. However, it is the last barrier to protect people from harm. As an auxiliary preventive measure, correct use of personal protective equipment can prevent or reduce the occurrence of safety accidents, etc.
Therefore, in the daily work of the laboratory, the importance of personal protective equipment is self-evident. Among them, hand protection is of utmost importance, because our hands are the most frequently used parts in experimental operations. Gloves can protect our hands from burns, punctures, and vibration injuries, and can also avoid direct contact with chemicals on the skin of our hands.
Laboratory members also need to be equipped with other necessary personal protective equipment, such as wearing white coats and masks.文本

The content of laboratory biosafety protection includes safety equipment, personal protective devices and measures (first-level protection), special design and construction requirements of the laboratory (second-level protection), strict management systems and standardized operating procedures and regulations.
Our laboratory has a dedicated biosafety officer.页面
