I can speak with personal knowledge only of Switzerland, but I believe
that similar things happen in other European countries. There is a
central registry (access only to a few sworn functionaries) where the
EXACT chemical composition of every component of a product is databased
(is that a word???). From this (or, if the substances are new, animal
experiments) a toxicity class is given to the producer or importer, 1 to
5 or non-classified, 1 being the most toxic. This allows the vendor to
put the appropriate labels on the product. ALL hydrazine compounds are
automatically Class 1k (carcinogenic), including the hydrobromide. Class
1 and 2 compounds need a special permit to purchase, normally given only
to graduate chemists or persons otherwise able to prove they have the
necessary technical competence to handle toxic substances. Most fluxes
fall into Class 4 (Class 5 is reserved for some household products).
Even Class 3 has severe restrictions for purchase. There is no way a
Class 1 toxic would ever be permitted for sale as a flux.
If the exact composition of a product is not correctly revealed, either
by analysis or by a certified declaration, the product is simply not
allowed to be sold. The penalties for false declarations/labelling
include a 0 star hotel room for a goodly length of time and a fine with
a large number of zeroes after a significant figure.
In the EU, such compounds require appropriate R labels, determined
similarly.
The MSDS is totally irrelevant to this determination of toxicity. The
authorities are aware that you can get away with murder (literally) with
an MSDS.
Hope this explains why I said what I said.
