各位老师、同学：
根据气象预报，台风 “蔷琵” 预计自今日（10 月 23 日）下午至 25 日白天，将对本市带来强风、暴雨影响。实验室存有危险化学品、高压气瓶、精密仪器、低温设备、生物样本等高危 / 贵重物资，受进水、停电、大风坠物影响风险较高。为严防台风引发漏水、触电、化学品泄漏、设备损毁、样本失活等安全事故，请所有实验室人员严格落实以下专项安全措施：
门窗与室外附属物排查加固 全面关闭、锁紧实验室门窗；检查外窗玻璃、窗外排风管、支架、外置探头、空调外机等，及时加固。窗台、走廊外侧、阳台、通风橱外沿严禁放置烧杯、试剂瓶、工具箱等物品，防止大风坠落伤人。
精密仪器、电气安全管控
台风来临前，暂停高风险、长时间连续运行类实验，按规范关停色谱、质谱、XRD、离心机等大型精密设备；确需持续运行的设备须提前评估风险，做好停机与应急处置预案并留存记录。
及时断电：除必须不间断供电的低温冰箱、生物安全柜等（提前确认 UPS 续航），其余仪器、加热装置、搅拌、泵类、插座全部断电，防止雨水渗入造成短路、起火。
检查配电柜、接线盒、地面插排有无渗水隐患，低洼实验室提前做好挡水、围堰。
危险化学品、气瓶、废弃物防护
易受潮、遇水反应试剂、氧化剂、腐蚀品抬高放置，远离门窗、地漏、低洼地面；做好防泄漏托盘防渗检查。
高压气瓶确认钢瓶固定链牢固，远离窗户、可能进水区域；
废液桶、固体废物收纳容器加盖密封，防止雨水灌入溢出。
低温样本、生物材料保障 超低温冰箱、液氮罐重点巡检；提前确认 UPS 供电、备用液氮储备；制定断电应急处置预案，做好样本转移备选方案，防止珍贵样本损毁。
应急物资与排水巡检 各实验室检查应急物资：吸水棉、沙袋、挡水板、防化手套、护目镜、吸附棉、应急照明、对讲机等是否齐全可用；留意实验室地漏、排水口，提前疏通，防止积水倒灌。楼宇管理员同步启动恶劣天气应急机制，重点值守实验室楼层。
现场行为管理 密切关注气象预警信息；严禁在实验室窗边、阳台观望风雨、拍照录像，防范玻璃爆裂、高空坠物伤人；风雨明显加剧时及时撤离实验室；积水区域禁止涉水，不要触碰浸泡的电器、线路。
应急联络方式（24 小时） 校内安全求助电话：20685110 校内抢修保障电话：20685112 如发生漏水、化学品泄漏、触电、火情等实验室险情，优先保障人身安全，撤离后立刻上报课题组负责人、学院 EHS 及上述应急电话。
台风警报解除前，请各位负责人督促落实实验室巡检，台风过后，须经安全检查确认无进水、漏电、泄漏隐患，方可恢复实验。
特此提醒。

Dear Faculty, Researchers and Students,
According to meteorological forecast, Typhoon “Champi” will bring strong wind and heavy rainfall to the city from this afternoon (Oct 23) to daytime Oct 25. Laboratories contain hazardous chemicals, high-pressure gas cylinders, precision instruments, cryogenic equipment and biological samples, which face high risks of water intrusion, power failure, falling debris and secondary hazards. To prevent accidents such as water flooding, electric shock, chemical spillage, equipment damage and sample loss, all lab users shall strictly follow the safety requirements below:
Doors, Windows & Outdoor Fixtures Lock all laboratory doors and windows securely. Inspect and reinforce exterior glass, exhaust brackets, external sensors and air-conditioning units. No glassware, reagent bottles or tools shall be placed on windowsills or outer ledges to avoid falling hazards.
Electrical Equipment & Precision Instruments
Suspend high-risk and long-duration continuous experiments before the typhoon. Shut down large instruments including chromatographs, mass spectrometers and centrifuges as appropriate. For equipment that must keep running, complete risk assessment in advance, prepare emergency response plans and keep relevant records.
Cut off power for heaters, stirrers, pumps and ordinary sockets. Only critical equipment such as ultra-low temperature freezers and biosafety cabinets may remain powered after verifying UPS backup capacity.
Check distribution boxes and floor sockets for water seepage. Deploy water barriers in low-lying labs.
Hazardous Chemicals, Gas Cylinders & Waste Place water-sensitive, corrosive and oxidizing chemicals on raised shelves away from windows and drains, with secondary containment trays in good condition. Secure high-pressure cylinders with restraints. Seal waste liquid and solid waste containers tightly against rainwater inflow.
Biological Samples & Cryogenic Assets Monitor ULT freezers and liquid nitrogen dewars. Verify UPS runtime and backup LN₂ supply, and prepare contingency plans for valuable biological samples in case of power outage.
Emergency Supplies & Drainage Check emergency kits: sandbags, water barriers, absorbent pads, PPE, emergency lights. Clear floor drains in advance to prevent backflow of rainwater. Building management shall activate severe weather emergency response for lab zones.
On-site Safety Rules Keep track of weather alerts. Do not stay near windows or balconies to watch or film the storm to avoid broken glass and falling debris. Evacuate promptly when wind and rain intensify. Never wade through flooded areas or touch submerged electric facilities.
24/7 Emergency Contacts Campus Emergency Hotline: 20685110 Campus Maintenance Hotline: 20685112 In case of flooding, chemical spill, electric hazard or fire, evacuate first and notify your PI, school EHS team and the emergency lines immediately.
Do not resume laboratory work until a full safety inspection confirms no water intrusion, leakage or electrical hazards after the typhoon warning is lifted.
