Subject: decommissioning fume hoods

DCHAS Listers:

My university is renovating an old science building and plans to decommissi
on and disassemble about 30 chemical fume hoods.  These hoods have not been
 used for over three years.

For which chemical residues do we need to test the exhaust ductwork and exh
aust fans before disposing or recycling these items?  Since these fume hood
s were abandoned, no one is sure what was used in them.  The previous owner
s are no longer at the university, so we can't check with them. I know we s
hould check for radioactive residues, perchloric acid, heavy metals, and ha
logenated organics, but is there anything else specifically?  

How do we decontaminate the ductwork and exhaust fans?  One site I checked 
mentioned washing with warm soapy water, but that was for the inside of the

Thank you very much.
