A walk through survey was undertaken to document and evaluate effective techniques for the control of potential health hazards at Widmer's Dry Cleaning (SIC-7216), Cincinnati, Ohio. There were about 85 employees at the facility. Closed loop, dry to dry machines and process isolation were in use to control exposures. The company appeared to have control methods in place which were able to maintain 8 hour time weighted average exposures to perchloroethylene (127184) to below 25 parts per million (ppm). The highest level reported was 20.5ppm for a machine operator. This level may have resulted from ineffective solvent recovery during the dry cycle. Better maintenance or more effective cooling coil performance could probably improve the recovery system. One practice observed at the site which could become a problem was allowing still runoff to remain exposed to the atmosphere until it cooled. Spotters were not using personal protective equipment during the use of hazardous chemicals. The authors recommend several other measures which could be adapted by the company for reducing even further the hazardous exposures to perchloroethylene. The authors conclude that an in depth study of this facility could be of value.
