Abstract
Worker exposures to lead (7439921) and copper (7440508) were surveyed on November 7, 1983 at Stuart Manufacturing Company (SIC- 3714) in Denver, Colorado. The evaluation was requested by the United Auto Workers Local 186 on behalf of 14 employees involved in heavy duty radiator production. Personal and area air samples were collected for lead and copper. Employees were questioned about work and medical histories, and blood samples were taken for lead and free erythrocyte protoporphyrin determinations. Local exhaust ventilation was measured on the dip tank hood. Three of seven personal air samples exceeded the 50 microgram per cubic meter (microg/m3) limit for lead, but all samples were below the 100microg/m3 limit for copper. The average capture velocity of the ventilation system was 250 to 300 linear feet per minute, which was considered adequate. Blood lead values averaged 37.2microg per deciliter for exposed workers compared to 18.6microg for unexposed subjects. Protoporphyrin values over 50microg per deciliter occurred in two of nine lead exposed workers, and these two workers also had elevated blood lead values. The worker with the highest blood lead value (52microg) and one other worker complained of symptoms such as headache, fatigue, irritability, metallic taste, and respiratory irritation. The authors conclude that a lead exposure hazard exists at this facility. They recommend improved housekeeping and personal monitoring for lead exposure.
