I really appreciate the CSB board (U.S chemical safety board), where they share detailed findings and learnings from incidents. It's always better to learn from others' lessons than ours.
While this video is related to school demonstration, it really also applies to students who are doing the laboratory experiments. We may sometimes be playful, sometimes be stressed to do things fast, but always think when you are in the laboratory, particularly during the handling chemicals and hot surfaces. What are the risks involved, why should you be doing/ why should you not be doing something, what are the potential consequences, and finally, always remember your personal protective equipment (e.g. safety googles).
The safety precautions --- you memorise them as part of your exams, but they are not just for exams, more importantly, it's for your own safety.
