Industrial Hygiene Report Walkthrough Survey of Toluene at United States Shoe Corporation, Harrison, Ohio.
NIOSH 1979 Jun:14 pages
A walk-through survey was conducted and past and present worker exposure to toluene (108883) was documented at the United States Shoe Corporation (SIC-3144) in Harrison, Ohio to assess the feasibility of a retrospective cohort mortality and morbidity study and to determine if a detailed industrial hygiene survey should be undertaken. Approximately 300 workers were potentially exposed to solvent based cements that often contained toluene in addition to other organic solvents. The company conducted air sampling in March, 1977 which indicated toluene concentrations of 15.06 and 19.96 parts per million (ppm). Threshold limit value sniffer readings on May 2, 1979 for total hydrocarbon concentrations were 20 to 120ppm. Drager tube readings for toluene were below detection to 20ppm, and charcoal tube readings were 0.9 to 19ppm for toluene, 2.6 to 4.5ppm for hexane (110543), and 0.09 to 45ppm for ethyl-acetate (141786). The authors conclude that exposures to toluene occur at the facility, but they are well below the threshold limit value of 100ppm, and that such low exposures are the result of a recently installed ventilation system. They recommend that the adequacy of this facility for a detailed industrial hygiene survey be evaluated after a comparison is made with other facilities under consideration.
