Health Hazard Evaluation Determination Report No. HE 80-99-707, Denver Dry Goods, Denver, Colorado

摘要

An environmental survey was conducted on April 15, 1980, to evaluate lithium (7439932) and lead (7439921) exposures resulting from the repair of the air conditioning system at Denver Dry Goods (SIC-5311) in Denver, Colorado. The evaluation was requested by an operating engineer on behalf of an unspecified number of workers. Exposures to lead and lithium were 0.03 and 0.008 milligrams per cubic meter (mg/cu m), respectively. General room air samples ranged from 0.008 to 0.01 mg/cu m for lithium and 0.01 to 0.02 mg/cu m for lead. All samples were well within the recommended OSHA concentration of 0.05 mg/cu m for lead and the threshold limit value of 0.025 mg/cu m for lithium. The author concludes that no hazardous exposures existed from exposure to lithium and lead. He recommends that smoking, eating, and drinking be prohibited in the work area, that workers wash hands thoroughly before eating, smoking, and snuff usage, that adequate respiratory protection be provided to all workers during the yearly cleaning of the air conditioning heat exchanger, and that workers be given clean clothes at the beginning of each shift.
