Asbestos Analysis: Airborne Fiber Count (NIOSH 7400)

Asbestos analysis includes testing of air sample for asbestos and other fibers by PCM. It is used primarily for estimating asbestos concentrations in air. It is used to show compliance with limits set by NIOSH, OSHA, and other regulatory agencies. The method does not differentiate between asbestos and other fibers and can also be used to estimate the airborne concentration of other, non-asbestos materials such as fibrous glass. Fibers less than 0.25 microns in diameter will not be detected with this method.
