Re: Decay on site question

[Dave Derenzo <dave@uic.edu>]

Dear Eileen,

I sent this yesterday, but I'm not sure it made it to the list.  I am also 
modifying/expanding my answer a little.  I apologize if this is a duplicate 
message.

We had storage bins made for us out of galvanized steel (good for fire 
safety).  Any good sheet metal fabricator should be able to make them for 
you.  Ours are installed on commercially available steel racks which we 
purchased from Grainger.  We use off-the-shelf Rubbermaid containers lined 
with heavy plastic bags to collect waste.  When removing the waste 
container from the lab, we close the bag with wire twist tie which has an 
attached ID tag.  Of course, we provide a replacement container to the 
lab.  The Rubbermaid container is then put into a storage bin, which is 
tipped back slightly to prevent any liquid (which shouldn't be there to 
begin with) from escaping.  Only after the decay period is over do we 
remove the waste from the Rubbermaid container.  In the many years of use, 
we have never had a contamination incident using this system.  If you want 
a photo, I can send one via email.  If you are looking for something that 
is more off-the-shelf, I suggest looking in warehouse equipment catalogs.

Hi,

we usually decay on-site our 32P, 33P and 35S. We are looking at upgrading 
our decay facilities and would like to find something along the lines of a 
"bank of lockers". Ideally we would be able to put waste with different 
start dates into different cubbies and then be able to remove just the 
one(s) that are ready for disposal and not be exposed to the ones that are 
still decaying. We would prefer an off-the-shelf type set up, but any 
suggestions are welcome. My email address is esdefeo@clontech.com

thanks very much for your time.

Sincerely,

Eileen
