A health hazard evaluation to determine possible hazardous exposure to monoethanolamine (141435) (MEA) and carbon-monoxide (630080) (CO) through leakage at Wheeling Pittsburgh Steel Corporation, (SIC-3312) Yorkville, Ohio was made. The plant is involved in treating and finishing steel produced in other facilities. The study was requested after sore throat complaints from workers in the HNX area where carbon-monoxide is oxidized to carbon-dioxide and removed using an MEA solution. MEA samples were collected on silica (7631869) gel. CO samples were collected using certified length of stain detector tubes. Employees were interviewed regarding work histories and health problems. Sixteen of 18 atmospheric samples of MEA were below the limits of detection by current techniques. The remaining two breathing zone samples of HNX operators were 2.1ppm and 1.0ppm. Such exposure might contribute to frequent sore throat complaints in employees. CO samples were below the recommended 8 hour time weighted average environmental limits. It was concluded that MEA exposure is a possible contributor to frequent sore throats among workers. Drying up standing MEA puddles, cleaning the substance from pipes and machinery, and reducing leakage were recommended.
