22. www.jst.umn.edu Refrigerator Blast A refrigerator door blew off and hit an inner pane of a double-paned window in a chemical lab at the University of South Florida. No one was injured in the blast, which set off a fire alarm about 2:45 a.m. Wednesday. The building did not catch on fire. 22 Chem lab refrigerator blast sets off fire alarm at USF. Tampa Bay Times. Accessed 8 March 2014 http://www.tampabay.com/news/publicsafety/fire/refrigerator-blast-prompts-fire-alarm-at- usf/2168615 http://www.tampabay.com/news/publicsafety/fire/refrigerator-blast-prompts-fire-alarm-at- usf/2168615 Tampa Fire Rescue's hazardous materials team responded: - no one was inside the building (no injuries) - no hazardous chemicals spilled - cause of the blast is being investigated.

23. www.jst.umn.edu Chemicals in Fridges and Freezers The atmosphere of a refrigerator could contain an explosive mixture of air & chemical vapors –To avoid inhaling vapors, don’t stick your head inside –Seal containers tightly (parafilm or tape are good options) Use a refrigerator approved for storage of these materials –Modified to not spark inside –Approved for “flammable storage” Store incompatible chemicals separately –Oxidizers and highly reactive in a separate unit from flammables. –Use secondary containment Air- and moisture- sensitive materials stored at low temp. are prone to problems exacerbated by condensation.

24. www.jst.umn.edu Azide Explosion Safety in the News

25. www.jst.umn.edu Report from C&EN “On June 17, an explosion […] injured a graduate student” 25 Flood Prevention in the Lab. 2010, Lab Manager. http://www.labmanager.com/lab-health-and-safety/2010/06/flood-prevention-in-the- lab?fw1pk=2#.VBNNG_ldUlk “The incident originated in lack of safety hazard awareness…” However, the injured student and his adviser were aware of the reaction hazards and the possibility of an azide side-product being produced.

26. www.jst.umn.edu Re-training Instinct The student had run this reaction many times. While complacency may have been a contributing factor to this incident, the student had set up engineering controls such as a blast shield to account for the large scale of the reaction. The student had also kept a close eye on his stir bar and reaction setup. When he spotted a problem, his instinct was to immediately correct the reaction setup, and not to put on PPE. 26 More details on the University of Minnesota explosion and response. July 30, 2014.
