Various exposure limits and analytical methods are recommended for hexavalent chromium exposures. While the OSHA standard is legally binding, NIOSH and ACGIH recommendations should be considered as well when determining personnel overexposures. Hexavalent chromium is linked to severe acute and chronic effects, including cancer. The United States Air Force currently uses NIOSH methods 7600 and 7605 to sample for hexavalent chromium. This research analyzed if personnel are being overexposed, in addition to comparing NIOSH 7600 and NIOSH 7605 results to determine if both methods are required, or if one can be used in place of both. The results of the sample data analysis indicated that hexavalent chromium samples obtained with both NIOSH methods exceeded the OSHA PEL of 5 ug/m3In addition, this study revealed that there were no significant differences in hexavalent chromium samples concentrations obtained with both methods.
