Ouendtadon of asbestos content was determined with a visual volume estimate, a calibrated visual area eaUingte, and/or point counting procedure, CAUTION: Other fibers with optical propefGas similar to asbestc may give positive IMerfereneas and will be considered asbestos under this methodology. Also, PLM is not consistently reliable In detecting asbestos in floor coverings and stmgar non-friable of anlcagybatnd maletiels.
