| Abstract |
On January 4, 1979, the National Institute for Occupational Safety and Health received a request to provide sampling and analytical assistance to the State of Ohio, Division of Occupational Health, for a determination of iodine vapor in the photopolymer plate processing area of the Container Graphics Corporation, Toledo, Ohio. The request generated the development of a new and reliable method for sampling and analysis of iodine. The conclusions and recommendations presented in this report are based on environmental measurements, observation of the work practices, ventilation measurements, professional judgement, and review of medical data and current literature. On April 5, 1979, airborne concentrations of iodine were measured in the workers' breathing zone and in the general work area. Two of five short-term iodine samples were above the Threshold Limit Value of the American Conference of Governmental Hygienists, and the Permissable Exposure Limit of OSHA. In addition, perchloroethylene, a solvent used by plate processors, was measured with values of 100-125 ppm, which is in excess of NIOSH's recommended ceiling value of 100 ppm. |
