Abstract
Airborne fiber identification and size distribution were studied in samples from an asbestos (1332214) insulation manufacturing facility (SIC-3292) of the Pittsburgh Corning Corporation in Tyler, Texas. Fibers were identified using a dispersion staining technique; fiber length distributions were determined using optical and electron microscopy. Sample fibers were identified as amosite (12172735) asbestos. Fiber size distribution data indicated that large quantities of the airborne amosite fibers in the facility were shorter than 5 micrometers. The authors note that when counting fibers using optical microscope techniques similar to those recommended by NIOSH, fibers less than 5 micrometers in length are not counted. They conclude that these techniques consequently provide only an index of asbestos exposure.
