Sampling and Analysis of Multi-Layered Materials.This accreditation is required for analyses being performed in compliance with AHERA regulations. National Voluntary Laboratory Accreditation Program (NVLAP), (September 22, 2011). Polarized light microscopy of asbestos Non-mandatory (Shipyard Employment).

Polarized light microscopy of asbestos Non-mandatory (General Industry).

Describes the collection and analysis of asbestos bulk materials by light microscopy techniques including phase-polar illumination and central-stop dispersion microscopy.

Polarized Light Microscopy of Asbestos.

Bulk analysis results will likely apply to both OSHA and EPA regulations. 9002, (August 15, 1994).īulk sample analysis should be done by Polarized Light Microscopy (PLM). Uses TEM to identify fibers (OSHA will accept this TEM procedure, as it uses PCM to determine exposure). A PCM procedure, equivalent to the OSHA methods.

NMAM also includes chapters on quality assurance, sampling, portable instrumentation, etc. NMAM is a collection of methods for sampling and analysis of contaminants in workplace air, and in the blood and urine of workers who are occupationally exposed.

NIOSH Manual of Analytical Methods (NMAM).National Institute for Occupational Safety and Health (NIOSH) Exposures should be evaluated with standard total dust sampling techniques for comparison to the OSHA permissible exposure limits (PEL). The following method has been adopted by many laboratories for the analysis of chemical compounds. OSHA has developed and validated methods for use by the Salt Lake Technical Center (SLTC) laboratory. Detailed procedure for asbestos sampling and analysis Non-mandatory (Shipyard Employment).Detailed procedure for asbestos sampling and analysis Non-mandatory (General Industry).OSHA reference method Mandatory (Shipyard Employment).OSHA reference method Mandatory (General Industry).Information available on the pages includes chemical identification and physical properties, exposure limits, sampling information, and additional resources. It compiles information from several government agencies and organizations. OSHA's premier one-stop shop for occupational chemical information. Transmission Electron Microscopy (TEM) methods may be used to identify fibers, but may not be used to quantify air concentrations for occupational exposure. PCM methods accurately assess fiber exposure levels, but PCM can not differentiate between asbestos and non-asbestos fibers. Medical surveillance guidelines for asbestos Non-mandatory.Įxposure monitoring samples must be analyzed by Phase Contrast Microscopy (PCM) for OSHA purposes. Interpretation and classification of chest roentgenograms (x-ray) Mandatory. Medical surveillance guidelines for asbestos Non-mandatory. Interpretation and classification of chest roentgenograms Mandatory. Medical surveillance guidance is provided in the following appendices to the OSHA Standards: Evaluating and Controlling Exposure Evaluating Exposureĭeterminations of employee exposure shall be made from breathing zone air samples that are representative of the 8-hour TWA and 30-minute short-term exposures of each employee.
