Ralph: Some of undergraduate lab experiments may work for your training:

1. Crystallization using a hot plate and a reflux condenser.
2. Distillation.
3. Column chromatography.
4. Running a gel which involves use of Ethidium bromide.
5. Rota vapor distillation.

Good luck.

Subject: [DCHAS-L] Examples of risk assessments for lab procedures?

I have the opportunity next month to do a lab safety training for a group of
undergrad students who are involved in a variety of kinds of laboratory
research. Of the 3 hours I have, I hope to include 20 to 30 minutes to do a
sample lab safety risk assessment for a simple chemical-oriented procedure
they may have some experience with, either in the research or classroom
environment. I wonder if anyone has specific suggestions for procedures that
work well in this context as a risk assessment exercise. I'd like to have it
complicated enough to have some unexpected results (e.g. gloves aren't need
in step 3-5, but are in 1 and 2) while being able to cover it in 30 minutes
or less.

Thanks for any suggestions about this.
