Abstract
Worker exposures to an organic hydrocarbon cleaner, Electrosol (8027541) were examined at the Amax Coal Company's Belle Ayr Mine (SIC-1211), Gillette, Wyoming. The study was requested by an employee and was conducted on June 15 and 16, 1982. Two breathing zone and three general area air samples were collected for methyl- chloroform (71556) which was being used to clean earth moving equipment. Breathing zone samples were 77 and 32 parts per million (ppm), compared to a NIOSH evaluation criteria of 350ppm. Area samples were 0.002ppm, 1.5ppm, and 4480ppm. This high value was probably caused by a direct splash of the methyl-chloroform during spraying. Individuals were observed smoking while working with the solvent, and direct skin contact with methyl-chloroform was also observed. No health complaints were reported. The authors conclude that environmental sampling did not indicate an overexposure to airborne concentrations of methyl-chloroform. Due to the possibility of workers receiving high exposures during cleaning, it is recommended that protective clothing and respirators with organic vapor cartridges be employed.
