Mary Beth (and list):

Rick Kelly at LLNL wrote a very good piece on perchlorate hoods. It is found here:

Kelly, Richard. Disassembling a perchlorate-contaminated ventilation system. Chem. Health Saf. 2000, 7(3), 5.

The DOI is here: http://dx.doi.org/10.1016/S1074-9098(00)00079-4

If you search on ScienceDirect, you will need to search Chemical Health and Safety, since the article was pre-"Journal of" days.

Best,

Harry

I recall an excellent presentation, years ago, from folks at from a large government lab who discovered this problem for many of their labs and came up with a good approach. This was part of a DivCHAS program at an ACS national meeting. Perhaps someone can remember the specifics, or if it was written up in JCHAS. -- Pete Reinhardt, Yale EHS

Does anyone have experience with the removal of perchloric acid hoods from a lab? Any information on the subject and references to resources capable of performing this task would be greatly appreciated. I do realize there is a special procedure and tremendous cost associated with this, but I wanted to get a better idea of specifically what is involved.

Thank you.
