FD-302a (Rev. 10-6-95) @ . @ ) 279A-WF-222936-USAMRIID While employed at USAMRIID, never observed any unknown or unauthorized person working in suites B3 and B4 in building 1425.. Regarding operation of the autoclave, one particular individual was not responsible for running the machine. Instead, each scientist and technician was responsible for autoclaving his or her own waste, and those individuals were responsible for legibly marking the material autoclaved. noted that the animal caretakers who entered thé suites daily to care for the animals being used for experimentation were responsible for autoclaving all of the animal waste and bedding materials from the animal cages. It was general knowledge that wet spore preps of the Ames strain of bacillus anthracis (BA) were made in suites B3 and B4. The walk-in cooler which was located in the common hall that internally connected suites B3 and B4 was a "busy" place, as it was used _by almost everyone with a laborato in suites B3 and B4. sed the vai cooler regularly. There were no sign-in procedures for the cooler. The following types of things were maintained in the cooler: reagent media, sterile media, sterile plates, buffers, innoculated plates from ongoing research, boxes of samples, and tins containing a variety of things such as organic reagents. It was not uncommon to find that when you placed your research material in the cooler, another researcher might move them to a different location in the cooler. Although s familiar with BA biology, did not conduct research regarding BA, and never worked with BA.
