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 http://www.aceglass.com/html/2008/html/index_html.php?page=714 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.
