28 octobre 2014
L’incendie a démarré dans la hotte aspirante du laboratoire. Le chercheur travaillait avec de l’uranium qui est pyrophorique. Le feu a dégradé un conteneur de pipettes usagées qui contenaient du technétium 99 pour une dose maximum donnée à 150 microcuries. Ce problème a entrainé la contamination de la hotte aspirante. Aucun opérateur n’aurait été contaminé et les filtres de la hotte auraient empêché la contamination de l’environnement. Le laboratoire a été fermé et une enquête est en cours.

AGREEMENT STATE REPORT - FIRE IN RADIOCHEMISTRY LAB CAUSES CONTAMINATION OF FUME HOOD
"On October 28, 2014 at 1615 PDT, a fire started in a fume hood in radiochemistry lab MSM 173 hood 2 [located at the University of Nevada, Las Vegas]. The researcher was working with uranium, which is pyrophoric. The fire damaged a container of used pipettes containing Tc-99 (maximum of 150 microCi), which resulted in contamination of the fume hood. The damage to the container and loss of integrity of the licensed material resulted in this report.
"The lab was immediately closed and surveys performed. There were no personnel or airborne contamination detected. The two HEPA filters for the fume hood exhaust prevented a release to the environment. The [licensee] issued a Stop Work order for all radiochemistry labs and initiated an investigation and will follow-up with additional reports to the Nevada Radiation Control Program."
