Abstract
Environmental and breathing zone samples were analyzed for methyl- chloroform (71556), benzene (71432), and mineral spirits at General Telephone and Equipment Company (SIC-3361), Carpenteria, California in January, 1985. The evaluation was requested by a union local to investigate whether employees working in the switching offices were exposed to excessive concentrations of methyl-chloroform, bank cleaning fluid, or lubricant while cleaning and lubricating mechanical switches. Five workers were interviewed to determine if they experienced any symptoms of overexposure to solvents. All mineral spirits and methyl-chloroform concentrations were below their relevant standards. No benzene was detected. Two workers reported dizziness, headache, or finger numbness about 15 minutes after using methyl-chloroform to clean rotary switches. One worker reported white fingers after using methyl-chloroform. None of the workers were wearing protective equipment or clothing. The author concludes that no overexposure to organic solvents is occurring. The reported symptoms are consistent with solvent exposure, most probably dermal exposure to methyl-chloroform while cleaning rotary switches. Recommendations include providing periodic training in chemical handling and instructing workers on how to use barrier cream when handling methyl-chloroform.
