What about this substitution of a hazard:  Use of commercially-available stabilized formulation of sulfuric acid and hydrogen peroxide, instead of concocting "piranha solution" from scratch, resulting in fewer reports of "out-of-control" piranha baths.  Cleanroom researchers adopted the substitute after it was introduced to them.

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.
