Prof. Jiaojiao Shang delivered a BMI lab safety training meeting on Jul 31, 2020. In the meeting, Prof. Shang introduced the four main modules of the safety system in BMI. Some important aspects were discussed, including the mandatory use of PPE in BMI lab areas, the classification of chemicals (general, toxic, organic solvents, etc.), the purchasing process of new chemicals and the use of online Chemical Inventory system, and the downstream process of organic and biohazard wastes. The purpose of this meeting is to further strengthen the sense of lab safety and revisit the essential knowledge of working in a high-standard and safe lab. After the meeting, the BMI domain leaders hold a panel meeting about the management of lab and future tasks for their leading roles in BMI.
