RE: Beryllium dust



Brent,

There is a company out there called Brush-Wellman, Inc., that specializes in
BeCu materials.  They seem to do a pretty good job of handling beryllium.
You can find them at: http://www.brushwellman.com/www/homepage.html

Subject: Beryllium dust


Hi from NH,
I have a client that works with a beryllium (62%), aluminum (38%) alloy.
The company machines this material using and EDM process.   All the cutting
is done submerged in water.  The water is filtered through a pair of 10
micron filters.  At this time they replace the filters 3-5 times a year
(6-10 filters/yr) but they expect the amount to increase significantly.
They are presently bagging the used filters and sending them to land-fill.
Exposure to the dust through inhalation can cause health problem and the
company is concerned that if the bag is torn, someone handling the bag for
the waste company could be exposed to the dust.  The material can't be
substituted for as it is specified by government contract.  Does anyone know
if this dust can be recycled or have knowledge of how to safely handle and
dispose of this material?

Thanks,
Brent Clement
