Just handling BeO is not hazardous, it's dust from dicing, sawing, machining
cracking it that can be hazardous. If the dust is fine enough it can get
into your lungs and in susceptible individuals repeated exposure will cause
berryliosis, for which there is no cure, and can be fatal.
No one knows who is susceptible or not and there is only one way to find
out. Therefore it is assumed that everyone is and it is handled accordingly.
Basically most end users don't machine it, so no special precautions need be
taken, although some people prefer respirators. Those that do cut it, do it
wet.

BE CAREFUL! BeO is a carcinogen! We have one product which uses BeO and we
have strict instructions for our technicians not to scrape it or do any
rework on it. When rework on the BeO is required, we send it to an outside
lab to handle. Unfortunately I am not aware what precautions are used to
mitigate the health risks associated with this material.

Subject: [TN] Micro-Sectioning Beryllia (BeO)
Fellow Technetters,
I'm looking for advice / partner lab. in connection with setting up a line
in our lab to handle micro-section preparation of beryllia (BeO). Does
anyone have experience of handling requirements and or line set-up? After
some initial research our lab manager it looks like we need to house a saw
and grind / polish station in a filtered fume hood (glove box even?). Key
requirement being the capture and safe disposal of any aerosol /
particulates generated through the micro-section preparation process.
Would really appreciate any feedback or contacts and chance to discuss.
Thanks and kind regards,
Stewart
