OSHA requires that all individuals performing analysis for air-borne Asbestos dust take the NIOSH 582 Equivalency Course. This 4-day program includes the setup, calibration and use of the Phase Contrast Microscope (PCM) to evaluate air-borne Asbestos Samples. This course also includes substantial field activities training. This course is recommended for all site technicians and consultants who routinely perform field activities.
