Dear Ralph, Sometimes the physical context and laboratory facility in which an experiment is conducted can adversely affect the risk. Please add to the risk assessment checklist facility factors, such as these for example:
Is the chemical fume hood (or other required primary containment device) operating?
Is there a current sticker or sign indicating this equipment has been checked and is operating properly?
Is there sufficient space within the hood or primary containment device to safely set-up and conduct the experiment?
Are all required utilities available and operating properly?
Is the required safety equipment available and operating properly?
Best regards,

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.
