The gentleman's name at ORNL is Marwan Bader (baderm**At_Symbol_Here**ornl.gov).

They remediated a system for me about 10 years ago. Its wise to do
this correctly. Our system was heavily contaminated. They were very
competent.
He had a separate company set up to perform the remediation. If you
have difficulty finding him I can look through my paper files and
get you the name of the company.

The program that Rick and others followed was from ORNL. I can put
you in contact with the program lead if you would like to talk to
him about the approach

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,

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.
