Venting Requirements for a Scint. vial crusher

["Smalts, Earl RSO" <ssdehs@msmail.ttuhsc.edu>]

We are currently looking into the possibility of obtaining a liquid 
scintillation vial crusher (Vyleater) to save on commercial disposal costs. 
 My question is that of concerning the venting considerations required by 
this piece of equipment.  Do we have to comply with the stainless steel 
mandates of a radiological fumehood, or can we merely install galvanized 
ductwork?  We are talking about subnanocurie amounts of aerisol being 
released from the machine's ventport during the crushing operation.  Also, 
are we required to install HEPA filtration on this particular unit.  I would 
greatly appriciate any and all comments from anyone knowledgable in this 
venture.
