Industrial Hygiene Report Walkthrough Survey of Toluene at Compo Industries, Inc., Mansfield, Massachusetts.
Worker exposure to toluene (108883) was determined and the feasibility of an industrial hygiene survey was evaluated at Compo Industries, Incorporated (SIC-2891) at Mansfield, Massachusetts on October 5, 1978. The work force consisted of 31 employees and the facility manufactured neoprene (9010984) cements and urethanes (51796) using toluene. A Century Total Organic Vapor Analyzer and Draeger tubes were used to measure total hydrocarbon concentrations. Toluene concentrations ranged from 11 to 270 parts per million (ppm) and total hydrocarbon ranged from 2.6 to 280ppm. In the urethane building, toluene and hydrocarbon concentrations were less than 1ppm and about 6ppm, respectively. Methyl-ethyl-ketone, (78933), acetone (67641), heptane (142825) and hexane (110543) concentrations were found. Most of the toluene concentrations were below the current threshold limit value of 100ppm and none of the samples collected represent 8 hour personal exposures. The authors conclude that concentrations did not exceed acceptable short term exposure limits. They recommend that a more detailed survey be conducted to characterize exposures and the evaluation should include personal monitoring.
