Description:In response to a request from Alma American Labs (SIC-1041), Fairplay, Colorado, an investigation was made of possible hazardous working conditions at the site, specifically employee exposures to lead (7439921). The company used a fire assaying process to separate noble metals from their ores using dry reagents and heat. Two assistants, one sample preparation employee, one chemist and two office workers were employed at the laboratory. Personal breathing zone and area air samples were collected, and employees completed a self-administered questionnaire regarding personal medical and occupational histories. Each employee was also subjected to a limited physical examination and a blood analysis for lead and free erythrocyte protoporphyrin. Two assay workers had full shift personal breathing zone air lead concentrations of 120 and 200 micrograms/cubic meter (microg/m3), compared to the OSHA permissible exposure limit of 50microg/m3. The blood lead levels for these workers were 39 and 55 micrograms/deciliter, respectively. Short term air sampling revealed that dispensing the flux contributed significantly to employee exposure. The authors conclude that a health hazard existed from exposure to lead in fire assay operations at this facility. The investigators offer recommendations designed to reduce the hazardous exposures.
