Health Hazard Evaluation Determination Report No. 79-73-601, Rocky Mountain Bank Note Company, Wheat Ridge, Colorado

摘要

Breathing zone and general air samples were taken on May 8, 1979 in the work areas of linotype and lead (7439921) melting operations at the Rocky Mountain Bank Note Company in Wheat Ridge, Colorado. Most of the 20 workers in these areas also were interviewed and monitored for possible lead exposure. The evaluation resulted from a request to NIOSH from company management. Breathing zone and general air samples were taken on AA filters using vacuum pumps. Samples were analyzed using atomic absorption techniques. The highest concentration of airborne lead observed (0.02 milligrams of substance per cubic meter of air) was less than the OSHA standard of 0.05 milligrams. Results of employee interviews and a review of the physical conditions of the workplace also revealed no health hazards. It is recommended that the workers continue the practice of washing their hands before eating and that no eating, drinking, or smoking be allowed at the work station.
