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:

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

large government lab who discovered this problem for many of their

the specifics, or if it was written up in JCHAS. -- Pete Reinhardt,

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.
