Demystify:
Replacing mercury thermometers in Teaching Labs. The replacements (mostly alcohol filled) were expensive to purchase & not really as good, but good enough. Hours
(& hour & hours�) of mercury cleanup saved, not to mention toxicity, loss of lab time�. For some classes, inexpensive solid state digital ones work fine.

In a conversation with a colleague today, I was thinking of examples of lab situations in which lab workers "naturally" (i.e. without prompting from EHS offices) developed alternatives to the use of risky chemicals. Examples I came up with
included the decrease of the routine use of benzene and Chromerge to wash glassware; and the development of nitric acid based microwave systems to replace boiling perchloric acid baths.
I wonder if there are other examples of such natural transitions that others on DCHAS-L can identify?
Thanks for any help with this.
