Suiting up for disaster Wasatch Front firefighters suit up for a mock chemical drill that one participant called the "Mother of all haz-mat drills." The Friday morning drill involved the creation of a complicated hazardous-materials accident: a railroad tanker car filled with nitric acid that had collided with a semitrailer truck carrying liquid waste acetone. Also on the scene was a 1,000-pound tank of leaking chlorine, several cartons of radioactive materials, a tank filled with a blasting agent and another tank filled with organic peroxide. One million trucks carry hazardous waste through Salt Lake City each year, plus rail car and airplane shipments. Some 29 firefighters from along the Wasatch Front participated in the event as a final exam after two weeks of training conducted by the state Comprehensive Emergency Management Department.
