Shocking safety precautions
As an ex-chemist with training in the industry (not university) I was shocked by the lackadasial handling of safety measures:
1. Liquid nitrogen is handled with unprotected hands, although there are some heavy duty gloves lying on the table. When the professor removed the funnel he nearly did have an accident.
2. No safety glasses worn by him or his assistents where liquid nitrogen and an explosion are involved.
3. No protective clothing to protect his body, especially his naked arms under a short-sleeved shirt.
Sad state of "teaching by example" in the universities.
