Subject: Research chemicals of unknown toxicity
In-Reply-To: A
Dear fellow ACS Div-CHAS members,

I'm looking for advice on what you tell your people about working with
chemicals of unknown toxicity.

In my current case, I have a researcher who will administer a compound
she is getting from a colleague at the EPA to mice. Some ata I have on
similar compounds show those chemical to be 'not very toxic' but I can
not find any information about this stuff.

I only half-jokingly suggested she obtain an MSDS from the EPA as they
are the supplier.

I'm inclined to tell them to treat the material as highly toxic and
collect the metabolites found in the mouse bedding/feces/urine and
handle as hazardous waste. At least until they have more information
about the hazards.

Do you agree? Do you have any particular guidance you would care to

Thanks in advance!
