各位老师、同学，
为确保寒假期间实验室安全，保障和维护校园稳定安全，现将有关要求通知如下。
寒假验室安全注意事项
1. 寒假期间实验室应做好人员管理，避免单独实验，避免无关人员进入（儿童、未经授权人员），做好寒冷天气防风、防滑、防冻、防塌、防高空坠物等防范工作。
2. 加强实验场所危险源的规范管理。强化危险化学品、高温高压设施、压缩气瓶、辐射源、生物危险因子、激光、强电强磁等安全管理，保管责任落实到人；规范实验场所危险废弃物暂存管理；加强实验场所用电、用气、用水的安全管理，特别对气瓶、加热设备、冰箱等容易引发火灾或爆炸危险的设施要加强管理，落实管理责任人，确保安全。
3. 强化遵守实验室各项规定，严格执行安全操作规程，做好个人防护（穿戴实验服、手套、护目镜等）。禁止在实验室内饮食、烹饪、留宿、使用电暖器。落实值日、安全检查制度，人员离开之前关好门窗、水、电、气。
4. 加强对实验安全的管理，特别是受低温影响的实验，以及不耐低温仪器设备、化学试剂等实验用具用品防冻工作。
5. 严禁在实验室内超负荷用电，严禁违规使用电器，电动车、电动车电池严禁进入实验室。
6. 禁止在具有火灾、爆炸等危险性实验场所使用明火；注意防火、防爆、紧急喷淋等应急设施的维护和正常使用。
7. 加强管制类化学品安全管理，加强易制毒、易制爆、易燃（如乙醇、石油醚、乙醚）、易爆等危险化学品的安全使用和存储。
8. 实验危险废弃物要按规定贴好标签置于安全区域，不得混入生活垃圾或直接倒入下水道。
9. 气瓶（钢瓶） 中压缩气体属于危险化学品，应合理固定、妥善存放，防止碰撞或倾倒。不使用的气瓶或使用完毕的气瓶，务必确保总阀关闭，以防气体泄漏。超期、报废气瓶应及时处理，不得存放在实验室。
10.完成2023年寒假期间实验室使用申报，夜间或高危实验须取得导师同意，并确保2人在场。
各单位要高度重视寒假期间实验室安全管理工作，强化安全责任，建立有效的事故防范措施和应急处置预案。
祝大家寒假愉快！

Dear all,
To ensure laboratory safety during winter vacation for the stability and safety of campus, general lab safety guidelines are provided as follows:
1. Unauthorized personnel is not permitted (children, solicitors) to enter labs. Cold weather precautions are advised to prevent slippery, freezing and falling objects, etc.
2. Strengthen the safety management of hazards in laboratories for hazardous chemicals, high temperature and high pressure facilities, compressed gas cylinders, radiation sources, biological risk factors, lasers, high-voltages, strong electricity and magnetism, etc., and implement custody policies; standardize the temporary storage and management of hazardous wastes at experimental sites; strengthen the safety management of electricity, gas and water use in laboratory, especially for gas cylinders, heating equipment, refrigerators and other facilities that are prone to fire or explosion hazards, and strengthen the responsibilities of person in charge.
3. Strengthen compliance with laboratory regulations, strictly implement safety operation procedures, and ensure personal protection (wear lab coats, gloves, goggles, etc.) equipment are properly wear. It is forbidden to eat, cook, sleep overnight, or use electric heaters in laboratories. Implement daily cleaning and safety inspection, and shut doors and windows, water, electricity and gas before leave.
4. Strengthen the management of experimental safety, especially experiments affected by low temperatures, as well as antifreeze precautions of experimental equipment and chemical reagents.
5. It is strictly forbidden to overload electricity in laboratories and illegal use of electrical appliances. Electric vehicles and their batteries are not allowed in laboratories.
6. It is forbidden to use open flames in sites with fire, explosion and other dangers; pay attention to the maintenance and use of emergency facilities such as fire extinguishers, explosion prevention, and emergency eyewash and shower.
7. Strengthen the safety management of controlled chemicals, and the safe use and storage of dangerous chemicals such as precursor to poison, explosion, flammable (such as ethanol, petroleum ether, ether), and explosive chemicals.
8. Experimental hazardous waste should be labeled and placed in a safe area according to regulations, and shall not be mixed with household waste or directly poured into the sewer.
9. The compressed gas in gas cylinders is a hazardous chemical and should be properly placed and stored to prevent collision or leakage. For cylinders that are not in use or are empty, be sure that the main valve is closed to prevent gas leakage. Overdue and waste gas cylinders should be disposed of in time and should not be stored in the laboratory.
10. Complete application of laboratory use during 2023 winter vacation, and obtain the consent of the supervisor for overnight or high-risk experiments, and make sure 2 people present on site.
All institutions should pay greater attention to laboratory safety during winter vacation, strengthen safety responsibility, and establish effective accident prevention and control measures as well as emergency response plans.
Have a nice winter holiday!
