Picard Catholic Schools Client: Alberta Infrastructure DST File No.: BE-ED Lab Report #: LR-ED Risk Level: High-risk - Second Floor Contractor: APSI Analysis Date: Air sampling cassettes were submitted to DST's laboratory for determination of fibre concentrations by Phase Contrast Microscopy (PCM). Samples were prepared and analyzed in accordance with the National Institute of Occupational Safety and Health (NIOSH) Method 7400, dated August 15, Analysis was performed using the "A" counting Rules. It should be noted that NIOSH Method 7400 does not differentiate between asbestos and other fibres. Only fibres with a length greater than 5 µm and a length-to-width ratio equal or greater than 3:1 were counted. Fibres with a diameter smaller than 0.25 µm cannot be detected using this method.
