Abstract:

On June 20, 1986, OSHA published revised standards governing
occupational exposure to asbestos, tremolite, anthophyllite and
actinolite in general industry and construction reducing the 8-hour
TWA PEL to 0.2 f/cc and establishing other protective provisions.
OSHA promulgated an excursion limit limit as 1 f/cc averaged over a
30- minute sampling period which was published as an amendment on
September 14, 1988 (53:35610). Now, OMB has approved the collection
of information requirements as they apply to the excursion limit.
