Rookie Lab Mistakes and Other Facts Not Found in Textbooks

[todd]

There will be a free webinar hosted on January 15th from 2-3pm EST by ACS on lab safety and how to avoid some common lab accidents and mishaps. You can register for the webinar here: https://attendee.gotowebinar.com/register/100000000065450169

More info about the webinar: here is a learning curve for everything, but mistakes made in the lab can ruin your research and cause dangerous accidents.  Tune is as Dr. Alison Frontier shares some trends that she has discovered after 10 years of running the website “Not Voodoo,” which provides a place where chemists of all types can submit what they have seen go wrong in the lab.  Join us to share your experiences, discover the most commonly reported lab mistakes, how they can be avoided, and take solace in the fact that everyone makes mistakes.   


Please let me know if you have any trouble signing up.

Hmm, some of these aren't very helpful... for example, we have no idea
what this means or what the implications are:
"Condensed liquid oxygen or solid argon with liquid nitrogen. (A
mistake you only make once.)"

http://chem.chem.rochester.edu/~nvd/pages/rookie-mistakes.php?page=just_wow

Why is it a mistake you make only once, is it because you just got
faced with an explosion, or is it because you just got fired for
wasting too much reagent, or did you get fired for ruining the gas
condenser?

It said "X or Y with Z"; what are the boiling points for those liquids?
What happens if you mix them by accident, and one boils
rapidly/explosively from the latent heat in the other?

Compressed gas is nasty business in untrained hands. I recall being at
Manchester Madlab when someone brought out the nitrogen to make icecream
in front of a bunch of kids. You could immediately ID all the people
who'd had gas training, because they all migrated towards the nearest
window and watched the kids intently! We resolved that as soon as one of
the "canaries" dropped, we'd all grab one and bolt for the door. :)
