This method is not applicable to samples containing large amounts of fine tilers below the resolution of the light microscope. The value of this method Is limited to the quantitative Idendflcation of asbestos and the semi-quamtutdve determination of asbestos content of bulk samples, expressed as a percentage of the protected area. Quandtaiion of asbestos content was determined with a visual volume estimate. a calibrated visual area esdtpats, and/or point counting procedure. CAUTION: Other fibers with optical properties similar to asbestos may give positive Interferences and will be considered asbestos under this methodology. Also, PLM le not consistently reliable in detecting asbestos in floor coverings and sirrdlar noMrlable organIcabllybound materials. Quantltagve transmission electron microscopy Is currently the only method that can be used to determine If (We material can be considered or treated as nonasbealos containing.
