SLi Asbestos Department

The Asbestos Department offers asbestos analysis of bulk materials by Polarized Light Asbestos and Fiber Count analysis of air samples by Phase Contrast Asbestos.  The foundation of our asbestos department is a strong training program for analysts.  In addition to extensive training for new analysts, we support regular training for all analysts. We continuously look for ways to improve our analysis, especially in the identification of the atypical asbestos minerals including Tremolite, Anthophyllite, and Actinolite.  Nikon Microscopes are used for all analyses.  Samples not consumed in testing (air samples and bulk samples) are maintained on premises for a minimum of 60 days before disposal by a hazardous waste contractor.  Client requests for returned samples are honored; likewise, samples may be held longer upon request.
