Abstract
Environmental and personal air samples were analyzed for the presence of free silica (7631869) at the Redfield Company (SIC-3832) in Denver, Colorado on September 26 and 27, 1977. The survey was requested by the employer on behalf of about 320 employees. Air samples were analyzed for total nuisance particles, respirable particles, and silica. No exposures exceeded the OSHA criteria of 5 milligrams per cubic meter for respirable or total nuisance particles, and no free silica was detected. High volume air samples detected silica as 23 percent of total dust and 16 percent of respirable dust, which exceed the OSHA criteria. The author concludes that a potential hazard exists from silica exposure and recommends that a medical and environmental monitoring program be established, the working environment be evaluated every 6 months, and a respirator use and care program be developed. Improved ventilation, housekeeping procedures, and worker protection practices also are recommended.
