Subject: Science Education & Safety - Follow-up
Thank you all for an insightful and informative discussion. I agree that we
should be teaching safety while we teach science (or chemistry in this
example) but alas I fear we could do much better. 


I asked for alternative extractions because I want to provide the faulty in
charge of this lab choices.

Of course, one of the choices will be to continue with their existing
experiment, but with a heightened degree of hazard control.


You see, I became aware of the use of dichloromethane when a student
received a few milliliters squirt into her nose, complained of breathing
difficulty and sought medical attention.


As always there's more to the story but in my opinion the teaching lab does
not seem to be providing adequate ventilation control or administrative
control when this happens....
