Subject: Pressure tube for organic synthesis
Dear All


Greetings from Singapore.


Has anyone encountered accidents involving glass pressure tubes which
were commonly used for organic synthesis in research labs? One example
of this can be found from Ace glassware 


We recently had an accident involving such a pressure tube which was
used for an organic reaction involving phenylmalemide, triphenylphospine
and para-formaldehyde in 3.4ml acetic acid, injuring 2 students who are
working in front of the fumehood. We are still investigating the
accident but initial assessment points to lack of hazard analysis as
well as other safety lapses.
