“Great! The breakdown of each analysis/test was very helpful in trying to master asbestos identification.” — Megan M.

“This class helped with the technical aspect of asbestos analysis” — Meredith O.

“Course was extremely well put together. There was no wasted time of effort.” — Ricky L.

“The staff is very excellent, professional, and knowledgeable. I knew I would learn what I came here to learn. — Jeff M.


Course schedule: 8:00 a.m. – 5:00 p.m. Monday – Thursday, and 8:00 a.m. – 12:00 p.m. Friday

Using polarized light microscopy (PLM), students study crystallographic and optical properties of asbestos minerals, the various substances likely to occur (and often confused) with asbestos and the procedures for sample preparation and fiber identification. Serpentine (chrysotile) and amphibole (amosite, crocidolite, tremolite, actinolite, and anthophyllite) asbestos varieties are included.
