Abstract
A Health Hazard Evaluation investigation was conducted by NIOSH in the chromium nitrate production (SIC-2819) area of the Allied Chemical Corporation facility in Marcus Hook, Pa., on November 21, 1976. An authorized representative of the employees requested the investigation in order to determine whether any substances normally found in the work areas had potentially toxic effects in the prevailing concentrations. The employee exposure to hexavalent chromium, as measured during the survey, did constitute a potential health hazard, both samples taken exceeding the OSHA ceiling standards of 100 micrograms of hexavalent chromium per cubic meter of air for chromic-acid (7738945) and chromates, as well as the NIOSH recommended ceiling of 50 micrograms per cubic meter for noncarcinogenic hexavalent chromium. Neither sample exceeded the recommended standard of 25 micrograms per cubic meter of breathing zone. The interview of one "affected" employee failed to reveal any health complaints. Recommended engineering controls to eliminate the potential health hazard include capture velocities of 100 to 200 feet per minute to control the dust release, a lateral local exhaust system around the rim of the material addition porthole, and improved respiratory protection program. A medical surveillance program that will allow the monitoring of chronic diseases, especially cancer, is also recommended.
