XI. Non-Mandatory Appendix - Sampling and Analytical Methods

The sampling and analytical methods for the substances listed in this appendix are not mandatory. They are listed to inform the public of methods and indicate that methods are available (or not available in 7 cases). They are categorized into three groups: (1) Fully Validated Methods, (2) Other Methods, and (3) No Methods. These methods are indicated in the tables in this Appendix. The first table details fully validated methods, other methods, substances for which there are no identified methods, and detection limits. The second table identifies the most recent NIOSH Analytical methods.

A. Fully Validated Methods

Fully Validated methods were developed by either NIOSH or OSHA. The criteria used in validating these procedures were developed independently by each agency. There are some differences in validation protocol, but in general similar testing procedures were followed. These methods are widely accepted by the scientific community.

B. Other Methods

Methods in this category have not been subjected to all of the testing procedures required of fully validated methods. Some of these procedures have been taken directly from scientific literature and may not have been used by OSHA. Some are methods that were validated for a specific analyte and OSHA believes are applicable for similar analytes. OSHA has reviewed these methods and has concluded that they are of adequate quality to be used for assessing exposures and for enforcement.

C. No Methods

These analytes do not have an adequate sampling method available at OSHA, nor has an appropriate method been found in the available scientific literature.

D. Detection Limits

The values listed under Detection Limits are the lowest air concentrations that can be monitored, based on recommended sample air volumes. Detection limits for the OSHA validated methods are determined during the evaluation. The detection limits listed for the in-house methods are the estimates of OSHA.
