National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Industrial Hygiene Survey Report of Polychlorinated Biphenyl Filled Transformer Production Operation, Westinghouse Electric Corporation, Sharon, Pennsylvania.

PB91115378

Publication Date	1977
Personal Author	Jones, M.
Page Count	18
Abstract	A walk through survey was made at Westinghouse Electric Corporation, Sharon, Pennsylvania for the purpose of determining the extent of worker exposure to various chemicals, including polychlorinated-biphenyls (1336363) (PCB) in the transformer production area. Air samples were collected to evaluate solvent exposures. Approximately 20 of the 3100 employees were involved in PCB operations. The personal air samples ranged from a concentration of 9.5 to 69.7 micrograms/cubic meter while the area air samples ranged from 28.4 to 56.7 micrograms/cubic meter for PCB. No concentrations of benzene, butyl acetate, ethyl-acetate, or methyl-ethyl-ketone were detected. One sample registered a xylene (1330207) concentration of 0.17 parts per million (ppm) and a toluene (108883) concentration of 0.6ppm. Another, saturated, sample contained 77.7ppm toluene. The author recommends that all operations involving PCB use should be carried out in a room with a negative ventilation system or outdoors. Local exhaust ventilation, protective clothing and organic vapor respirators should be used for work with PCBs. PCB contaminated material should be disposed of in appropriate containers and sent to an appropriate disposal site. The process has since been shut down.
