Assessment and Control of Chrysotile Asbestos Emissions

Chrysotile fibers were positively identified by morphology and by selected area electron diffraction (SAED). Chrysotile fibers have a unique tubular morphology that can be easily distinguished from other types of asbestos. Nearly all the Chrysotile fibers observed were shorter than 5.0 urn in length and less than 1.0 urn in diameter.
