This sounds kind of interesting but I begin to question the validity of the
entire enterprise (especially their stated concern for safety) when I see
that benzene is one of the compounds provided with their kit AND that the
MSDS they offer for benzene not only lacks any mention that it is a known
human carcinogen, but includes the line "Chronic Exposure: No information
found." (It does state "Known Carcinogen" under Section 16: other
information)

It also states in Section 8 that no airborne exposure limits have been
established while burying the OSHA and ACGIH limits in Section 15
Regulatory information.

I've not checked any of their other MSDS, but benzene is so widely known in
this regard that I have to wonder what these people think they are doing.

Here's something that I think will interest many on the DCHAS-L list... it
addresses chemical safety issues in interesting ways.

This is the chemistry set you always wanted as a kid but either didn't get
it or you got stuck with some cheap plastic wannabe...
