In response to a request from an employee representative, a hazard evaluation was conducted at LTV Steel (SIC-3312), East Chicago, Indiana, concerning machine shop exposures to a solvent containing 1,1,1-trichloroethane (71556) and dioxane (123911). Two 15 minute personal air samples yielded concentrations of 1,1,1-trichloroethane of 15.2 and 36.0 parts per million (ppm). Only one of five samples produced a detectable amount of dioxane, but it was still too low a concentration to be quantifiable. No health problems related to the use of solvents in the machine shop were reported by eight of ten employees interviewed. Symptoms in the other two workers were not what would be expected from the exposure levels found. The author concludes that no unacceptable hazardous conditions were identified during this investigation. The author recommends actions to be taken to further reduce exposures. Protective gloves should be used by those who would otherwise experience skin contact with the solvents. Workers should also wear splash proof safety goggles. Unnecessary use of the solvents should be avoided and skin which has come into contact with the solvents should be washed with soap and water as quickly as possible. Solvent should not contact flames or red hot surfaces. Ventilation should be adequate in any area where solvents are used.
