Description:An environmental survey was conducted on December 18 and 19, 1979 at Duralectra(SIC-5051) in Natick, Massachusetts to determine employee exposures to methyl-ethyl-ketone (78933), trichloroethylene (79016), toluene (108883), nitric-acid (7697372), sulfuric-acid (7664939), and phosphoric-acid (7664382). Thirty workers are currently employed at this facility and they requested the evaluation. Employees were interviewed regarding work histories and general physical condition. Personal and area air were collected, and analysis was done by gas chromatographic colorimetric and titration methods. Methyl-ethyl-ketone concentrations ranged from undetectable to 134 milligrams per cubic meter (mg/cu m), trichloroethylene concentrations ranged from 1 to 38mg/cu m, and toluene ranged from undetectable to 8mg/cu m. Nitric, sulfuric and phosphoric-acid ranged from 0.2 to 0.15 mg/cu m, 0.04 to 0.19mg/cu m, and undetectable to 0.04mg/cu m, respectively. All samples were below the OSHA exposure limits of 590, 535, 375, 5.0, 1.0 and 1.0mg/cu m for methyl-ethyl-ketone, trichloroethylene, toluene, nitric, sulfuric and phosphoric-acid, respectively. The authors conclude that a potential health hazard existed at the time of this study and they recommend improved housekeeping and personal hygiene practices. [Description provided by NIOSH]
