Plasma cutters

Similarly, the tie bar s on the outer neutron shield will be cut at stages to ease the removal of graphite bricks in the outer neutron shield. To perform the standpipe cutting an internal plasma cutter has been developed which has an integral grab to remove the waste item after it has been cut. The tie bars will be cut using a grinder deployed by the RDM manipulator.

In this example, the worker was using a plasma cutter without a face shield and synthetic gloves to cut open a 55-gallon metal dmm that had not first been properly cleaned or decommissioned. An effective PPE hazard assessment would produce the following information for the task of using a plasma cutter ... 

Human serum transferrin has been prepared in the laboratories of the University of California, Davis, from Cohn fraction IV—7 obtained from a commercial company (Cutter Laboratories, Berkeley, California). Such fractions are, of course, from plasma of a large number of individuals and may have been exposed to different treatments. For example, some of these fractions have been exposed to a heating step to inactivate viruses. This type of human material, which is the usual type used for large scale preparations, certainly contains different molecular forms, because of genetic differences, as well as some artifactual materials. The procedures employed molecular filtration on Sephadex columns and sequential ion exchange chromatography on anion and cation cellulose exchangers (22, 137). 

After Ed s move to Einstein in 1956, a joint U.S. patent in the public interests was filed (together with H. M. Tsuchiya and N. N. Heilman) on the practical production of the Streptococcus DS-50 dextran. Pilot plant production was undertaken at NRRL clean-up and bottling were carried out as a service by the Cutter Corp. and a successful clinical trial of the dextran for treatment of patients in shock was conducted by Dr. W. Metcalf of Einstein s Department of Surgery. Ed presented a final report to the National Research Council in 1962. In the end, despite the discovery of a simpler way to manufacture a product of great potential military usefulness, dextran in general would be replaced by blood and plasma as agents of plasma volume expansion in shock patients.
