Description:In response to a confidential employee request, an investigation was begun into possible exposures to solvents at Automotive Controls Corporation (SIC-3694), Independence, Kansas. Workers were concerned about exposure to solvents, including dioxane (123911) and 1,1,1-trichloroethane (71556) (TCE) used to wash parts in the Hybrid Department. Problems included weakness, shakiness, blurred vision and eye irritation, inability to think or talk, depression, and respiratory and thyroid problems. The Hybrid Department produced ignitions, regulators, and distributorless ignition systems, and had 60 workers on two shifts. Full shift personal breathing zone (PBZ) exposure for TCE ranged from 69 to 198 parts per million (ppm), all below the OSHA exposure limit of 350ppm. PBZ exposure for dioxane ranged from 1.5 to 13.3ppm
all 21 samples taken exceeding the NIOSH recommended ceiling of 1ppm. Short term PBZ exposures were 422ppm for TCE and 11.8ppm for dioxane. Full shift area concentrations ranged from 92 to 1517ppm for TCE and from 2.5 to 51ppm for dioxane. These were highest for both compounds inside the storage room at the wash sink and at each degreasing tank at breathing zone level for the workers. The authors conclude that a health hazard existed from dioxane and TCE exposures at the time of the survey. The authors recommend that solvent concentrations in the Hybrid Department be reduced
the local exhaust ventilation system should be improved, and work practices should be used to reduce exposures.
