Description:Environmental and breathing zone samples were analyzed for chlorine (7782505) (Cl), asbestos (1332214), and chromium (7440473) and nickel (7440020) welding fumes at Pennwalt Corporation (SIC-2812), Portland, Oregon in March, September, and October 1979, and April 1980. Evaluation was requested by the International Chemical Workers Union to evaluate possible work-related pulmonary disease and excess morbidity and mortality from cancer and heart disease among employees. Medical questionnaires were administered to 150 workers. Company medical records were examined. Cl concentrations ranged from 0.01 to over 1.5 parts per million (ppm). The OSHA standard is 0.5ppm. Asbestos and welding fume exposures were below the OSHA standards. Company records showed no evidence of an increased incidence of abnormal chest X-rays, electrocardiograms or pulmonary function tests. No evidence of an excessive incidence of heart disease was found. The authors conclude that there is no work-related excessive incidence of pulmonary or heart disease. The number of cancer deaths is too small to determine if there is a significantly increased incidence. Recommendations include use of NIOSH approved cartridge respirators, and local exhaust ventilation in welding operations.
