NIOSH Testimony on Occupational Exposure to Asbestos, Tremolite, Anthophyllite, and Actinolite by R. W. Niemeier, January 4, 1993.
NIOSH 1993 Apr:5 pages
This testimony provided comments to OSHA from NIOSH regarding supplemental information on issues related to occupational exposure to asbestos (1332214). One of the concerns was a lack of a definition from OSHA of asbestos containing material (ACM). If this designation indicated the presence of at least 1% asbestos, there was no available method to accurately measure low levels. NIOSH also testified that building records may be unreliable or incomplete and that building owners should not be allowed to use these records to rebut the presumption that building materials contain asbestos. The exemption of buildings constructed before 1920 was also questioned, since most such buildings would have had major renovations which could have included asbestos containing materials. No studies have been conducted by NIOSH of exposure during small scale, short duration maintenance or custodial operations. NIOSH studies on the effectiveness of negative pressure glove bags, and control technology for asbestos removal activities were cited. Other published studies on asbestos exposure during maintenance activities were also cited.
