Environmental and medical surveys were conducted on April 11, 1978, to evaluate exposures to Freon-11R (75694), hydrofluoric-acid (7664393), nitric-acid (7697372), and acetone (67641) during the etching and polishing of components at the FMC Corporation in Broomfield, Colorado. The evaluation was requested by a management representative on behalf of approximately 25 affected employees. Environmental air samples were all within the most recent evaluation criteria. Confidential employee interviews showed no health complaints or symptoms. The author concludes that a health hazard did not exist at the time of the evaluation. The author recommends that adequate protection be provided against accidental exposure to hydrofluoric-acid and that all ventilation hoods be checked frequently to ensure proper air flow.
