Letters of Interpretation
- Use of "objective data" to accurately characterize employee exposures to hexavalent chromium during welding operations. (November 14, 2006).
- Maintenance and preservation of employee exposure records. (April 1, 1999).
- Clarification of the requirements of the Hazardous Waste Operations and Emergency Response Standard. (October 31, 1997).
- The appropriate method for assessing hydrogen sulfide peak exposure levels. (September 28, 1995). Describes the appropriate method for assessing hydrogen sulfide peak exposure levels.
- Sampling for benzidine congener dyes. (January 18, 1991). Describes sampling and shipping methods applicable to these dyes.
- Use of X-ray fluorescence (XRF) is not acceptable to determine employee lead exposures. (May 8, 2000). Provides an explanation of why OSHA does not use XRF in the evaluation of lead exposures, clarifying that OSHA does not rely on bulk and surface measurements for evaluating employee exposures.
- Wood dust sampling. (April 22, 1993). Clarifies that respirable sampling is not recommended for wood dust.
- Sampling Procedures for Employees Using Air-Supplied Respirators. (June 27, 1989). Clarifies that employee exposure samples are not to be collected inside the hood of an air-supplied respirator.
