A quick google search revealed the following: http://www.genevac.com/info/news-03.html http://www.ehs.cornell.edu/lrs/CHP/12.peroxides.htm http://www.chemistry.mcmaster.ca/health&safety/safety/htm/d.htm http://www.safety.ed.ac.uk/resources/occ_hygiene/Updates/hygiene_update12.html And http://www.umanitoba.ca/campus/health_and_safety/explosives.html in which it appears they have cribbed a fair portion of Rick Kelly's (LLNL) paper on peroxidizable compounds. And this one that has descriptions of a variety of lab accidents with corrective actions noted - this is probably of wide interest to the group (it is good to be a hunter/gatherer): http://www2.umdnj.edu/eohssweb/aiha/accidents/explosion.htm Is this what you're looking for? If you're looking for brissance or explosive force, I don't think you'll be able to find that data since peroxidized ethers are not a material of interest to those interested in blowing stuff up. People have lost all sorts of body parts from exploding ether cans. There may be fatalities - Jim Kauffman at the Lab Safety Intitute (www.labsafety.org) would know. I would not mess with this can. I'd call up a reactives disposal firm and let them deal with it. Debbie At 02:19 PM 4/29/2005 -0500, Kent Candee wrote: >Debbie: > >Anthony's advice is good and correct.
