Evaluation of airborne asbestos () fibers by the membrane filter method (NIOSH Analytical Method Number P/CAM ) is described. The purpose of the method is to determine worker exposure to airborne asbestos fibers as referenced in the Federal standard on occupational exposure to asbestos and the Mine Safety and Health Administration air quality standards.

Cincinnati, Ohio: U.S. Dept. of Health, Education, and Welfare, Public Health Service, Center for Disease Control, National Institute for Occupational Safety and Health ; Springfield, Va.: Available from National Technical Information Service, (OCoLC) Air is drawn through a MCE filter to capture airborne asbestos fibers.

A wedge shaped portion of the filter is removed, placed on a glass microscope slide and made transparent.

A measured area (field) is viewed by PCM. All the fibers meeting defined criteria for asbestos are counted and considered a measure of the airborne asbestos concentration.

NIOSH's air monitoring method involves drawing a measured amount of air through a filter and counting the fibers on the filter using a technique called Phase Contrast Microscopy.

Early researchers looking at asbestos exposure in buildings with friable asbestos-containing material attempted to use air monitoring with the NIOSH technique.

A minimum length for asbestos fibers ( μm) was specified for the first time to improve the reproducibility of fiber counts. This analytical method is widely used in the United States. Not all airborne fibers are asbestos and, inNIOSH issued its first TEM asbestos method (NIOSH, ).

Me thod is an optical counting procedure for airborne fibers in personal samples. Methods (Asbestos by Transmission El ectron Microscopy) and (Asbestos by Polarized Light Microscopy) are also useful for positive. To measure airborne asbestos and other fibers, an air sample must represent the actual number and size of fibers.

Typically, mixed cellulose ester (MCE, or microm pore size) and, to a.

The sampling pro- cedure conforms to the method described in USPHS/NIOSH Membrane Filter Method for Evaluating Airborne Asbestos Fibers (DHEW/NIOSH Publications Number ) in all of its major aspects except that Nuclepore® (poly- carbonate) filters are used in lieu of cellulose ester filters.The USPHS/NIOSH Membrane Filter Method is used to monitor for asbestos in occupational and mining atmospheres, and employs the phase-contrast optical microscope (PCM) that .The method gives an index of airborne fibers.

It is primarily used for estimation asbestos concentrations, though PCM does not differentiate between asbestos and other fibers. Use this method in conjunction with electron microscopy (e.g.
