• Description:
  Environmental air samples of airborne dusts, metals, gases, vapors, and fumes were collected, and a medical evaluation was conducted on November 29, 30, and December 1, 1978 and February 12 to 14, 1979 at the Arapahoe Aluminum and Brass Foundry, Inc. (SIC-3361), in Englewood, Colorado. The evaluation request to identify any potentially toxic workplace exposures for approximately 50 employees came from an employer representative. Concentration of inorganic lead (7439921) ranged from 0.03 to 3.2 milligrams per cubic meter (mg/cum) and exceeded the OSHA standard of 0.05mg/cum in 44 percent of the samples. Crystalline silica (14808607) concentrations exceeded the OSHA standard of 0.29mg/cum in 77 percent of the samples. All other sample concentrations were below criteria. Blood lead concentrations exceeded the OSHA standard of 40 micrograms per 100 grams of whole blood in 81 percent of the workers, and 72 percent had free erythrocyte protoporphyrin determinations above the normal range of 356 to 662 micrograms per liter of red blood cells. The investigator concludes that workers were exposed to hazardous concentrations of inorganic lead and crystalline silica, and other toxic exposures could occur if production conditions change without corresponding ventilation improvements. The use of respirators, protective hearing devices and clothing
  
  improvements of workplace hygiene and ventilation systems
  
  and periodic medical surveillance until all exposures are below criteria are recommended. [Description provided by NIOSH]
