NIOSH (National Institute for Occupational Safety and Health) Testimony to DOL (Department of Labor) on Occupational Standard for Benzene by E. Baier, July 25-26, 1977.

PB87220943

Publication Date	1977
Page Count	19
Abstract	The effects of occupational exposure to benzene (71432) on human health were discussed. After a brief mention of earlier findings, most of the testimony revolved around an ongoing mortality pattern study of workers exposed to benzene during the manufacture of a natural rubber cast film with the trade name Pliofilm. The cohort demonstrated a five-fold excessive risk of total leukemia and a ten-fold excess of myelogenous and monocytic leukemias combined. Employees' 8-hour time-weighted average exposures were fairly consistent with the recommended standard in effect at that time. In areas where excessive concentrations of benzene occurred, respiratory protection was required. A modification was recommended in the sampling and analytical method recommended by NIOSH in the criteria document. According to the testimony, employees should be educated as to the potential dangers from benzene exposure, continuing education programs should be in place, and monitoring and recording of engineering control data should be emphasized to assure that engineering controls are effective and working properly.
