Chromate Sampling Methods and Data Analysis
Abstract
The major health issues surrounding occupational exposure to chromates is very well summarized in the National Institute for Occupational Safety and Health (NIOSH) publications. The OSHA Ceiling Standard, 29 CFR 1910.1000 Table Z-2, for chromic acid and chromate is 1.0 mg/cu m. The ACGIH Standard is more complex, it considers chromates 'Confirmed Human Carcinogens' based upon epidemiological studies. There are two analytical methods typically used when quantifying chromate exposures. The first method is a general metals screen, NIOSH Method 7300. The second method is a specific analysis for hexavalent chrome, NIOSH Method 7600. There are three different calculations depending upon the analytical method used. Methods for reducing chromate exposures follows classical industrial hygiene protocols: Substitution, Engineering, and Administrative controls.
