Subject: RE: [DCHAS-L] Decommissioning Fume Hoods/Traps

We decommissioned an older hood not too long ago and were surprised to find an old fire extinguisher system inside.  No one here knew how it worked or why it was there, but it contained a very hazardous bromine compound (whose name escapes me).  It was a small amount, so it ended up not being dramatic or expensive to dispose of.  It did, however, take some ingenuity to remove it from the housing and the antiquated alarm system in the hood.  If your hoods are older, you might want to check for such things. 

We also recently moved a hood in which work with elemental mercury is performed.  I used an outside contractor to perform a complete decontamination of the hood before I would let the construction contractor do anything in that room.  

Unfortunately, they didn=92t do a very good job and we found beads of mercury all over the floor and in many parts of the hood.  Before we proceeded, the contractor had to come back out and finish the job correctly.  In retrospect, I should have had a more defined scope of work and a more detailed clean up check list for the mercury hood.  Just something else to be aware of.
