Study Plan. Control Technology Assessment of Chemical Process: Batch Unit Operations.

PB90142696

Publication Date	1981
Page Count	78
Abstract	The scope of the report was to discuss the study plan devised for the evaluation of technology used to reduce or prevent occupational exposure to hazardous chemicals during batch chemical operations in the synthetic organic chemical manufacturing industries. The primary concern of the effort was batch operations as their cyclical nature placed more stress on the control mechanisms in place and particularly on sealing device components than did continuous operations. A study of continuous process operations was not precluded, however, since these results may be readily applied to batch operations. Some of the control technology to be investigated included the use of valve seals, pump seals, agitator and compressor seals, other rotating and reciprocating seals, pipe flanges, equipment body flange seals, process stream sampling, and communication with the workplace during hazardous operations. Controls considered in the study included not only engineering controls but also monitoring devices, changes in work practices, and the use of personal protective equipment.
