Air sampling for asbestos (1332214) dust was conducted at the Johns- Manville Textile Facility (SIC-2221) in Manville, New Jersey, during January, 1965. All samples were collected with an impinger and a membrane filter sampler. Breathing zone samples collected with the impinger contained 0.2 to 10.6 million particles per cubic foot (mppcf). Unattended samples taken by a sequential impinger ranged from 0.2 to 1.8mppcf. Membrane filter breathing zone samples contained up to 22.4 fibers greater than 10 microns in length per cubic centimeter (f/cc). Personal air samples taken with the membrane filter ranged from unmeasurable to 16.4f/cc, while sequential samples contained up to 2.5f/cc.
