Environmental samples to measure airborne particulates and lead (7439921), and blood samples to assess lead and free erythrocyte protoporphyrin (FEP) content were taken at the Baumer Radiator Works (SIC-7539) in Denver, Colorado, on August 7, 1979. An evaluation request came from the owner and manager of the facility to determine the hazards from lead fumes and nuisance dust for an unspecified number of employees. One worker and the manager were exposed to airborne lead concentrations of 100 and 50 micrograms per cubic meter, respectively. The OSHA standard for lead is 50 micrograms per cubic meter. Blood lead concentrations ranged from 29 to 65 micrograms per 100 milliliters (ml), and FEP concentrations ranged from 926 to 2,212 micrograms per liter of red blood cells. The normal range for blood lead is below 40 micrograms per 100 ml, and for FEP it is 220 to 870 micrograms per liter of red blood cells. Airborne particulate concentrations were below the OSHA standard of 15 milligrams per cubic meter. The author concludes that a health hazard due to lead exposure existed at this facility, and had existed for the past several months. Recommendations resulting from the evaluation include improvements to housekeeping and personal hygiene practices, and use of local exhaust ventilation during the soldering process.
