| Abstract |
Worker exposures to chromic-acid (CrO3) were surveyed at Ohio Valley Graphic Arts (SIC-3471) in Cincinnati, Ohio, on November 20, 1973. No preemployment or periodic physical examinations were required. Serious injuries were treated at the local hospital. Production employees were given safety glasses and gloves. Air samples to measure chromic-acid exposures, chemical wipe samples to detect hexavalent chromium (7440473) (CrVI) and ventilation measurements were taken. The OSHA 8-hour time weighted standard for CrO3 is 0.1 milligram per cubic meter (mg/cu m). Concentrations of CrVI ranged from 0.0091 to 0.4825mg/cu m and CrO3 concentrations ranged from 0.0174 to 0.9264mg/cu m. Ventilation rates ranged from 500 to 1000 feet per minute. The author recommends implementation of appropriate safety, hygiene and medical programs. |
