Air Sampling for Asbestos and Fibers

  • Asbestos and Other Fibers by Phase Contrast Microscopy (PCM) - NIOSH Method 7400

    This method is for the analysis of asbestos in air by Phase Contrast Microscopy. Results are reported as fibers per cubic centimeter and depend on the volume of air sampled. PCM analysis is not asbestos fiber specific and will count all fibers meeting the methods criteria for fiber determination.

  • Appendix A to Subpart E of Part 763, Interim Transmission Electron Microscopy (TEM) Analytical Methods

    Mandatory, Nonmandatory and Mandatory Sections to determine completion of response actions. This method is for the analysis of asbestos in air by Transmission Electron Microscopy. Results are reported as structures per square millimeter and are specific for the determination of asbestos fibers present in the sample. This procedure is typically required in Schools K-12 after completion of an asbestos abatement project, for final re-occupancy criteria.
