On June 17, 1986, OSHA issued revised standards governing occupational exposure to asbestos for general industry (29 CFR 1910. 1001) and construction (29 CFR 1926.58), (51 FR 22612). These standards reduced the 8-hour time weighted average (TWA) permissible exposure limit (PEL) tenfold to 0.2 fibers per cubic centimeter of air (f/cc). On July 20, 1990, OSHA proposed revisions addressing the remaining remand issues.

Occupational Exposure to Asbestos

AGENCY: Occupational Safety and Health Administration, Department of Labor.

ACTION: Final rule.

Abstract:
Amendment of the Occupational Exposure to Asbestos, Tremolite,
Anthophyllite, and Actinolite standard (1910.1001). establishes a
permissible exposure limit of 0.2 fiber per cubic centimeter of air
(f/ cc), determined as an 8-hour time-weighted average airborne.
Applies to all industries covered by the Occupational Safety and
Health Act including the construction and maritime industries and
general industries.

Abstract:
Occupational exposure to asbestos, tremolite, anthophyllite and
actinolite for general industry (1910.1001) and construction
(1926.58) which were promulgated on June 17, 1986 and were published
on June 20, 1986 and became effective on July 21, 1986 (51 FR
22612).

Abstract:
Extension of partial administrative stay of the revised final
standards for occupational exposure to asbestos, tremolite,
anthophyllite, and actinolite for general industry (1910.1001) and
construction (1926.58), insofar as they apply to occupational
exposure to non-asbestiform tremolite, anthophyllite and actinolite.
The current partial stay which expired on April 21, 1987 is being
extended until July 21, 1988. Minor conforming amendments to notes
to the affected standards are also being made.

Abstract:
Corrections to the preamble of the final rules for Occupational
Exposure to Asbestos, Tremolite, Anthophyllite, and Actinolite (51
FR 22612, June 20, 1986) and technical amendments to 29 CFR Parts
1910 and 1926.

Abstract:
OSHA is hereby extending the partial administrative stay of the
revised final standards for occupational exposure to asbestos,
tremolite, anthophyllite and actinolite for general industry [1910.
1001] and construction [1926.58], insofar as they apply to
occupational exposure to non-asbestiform tremolite, anthophyllite
and actinolite.

Abstract:
On June 20, 1986, OSHA published revised standards governing
occupational exposure to asbestos, tremolite, anthophyllite and
actinolite in general industry and construction. In these standards,
OSHA reduced the 8-hour time weighted average (TWA) permissible
exposure limit (PEL) to 0.2 f/cc but did not issue a short term
exposure limit (STEL) or excursion limit for exposure to these
materials. OSHA is now amending these rules by adding an excursion
limit of 1 f/cc average over a sampling period of 30 minutes.

OSHA is conducting supplemental rulemaking on its standards, issued 6/17/86, for occupational exposure to asbestos, tremolite, anthophyllite, and actinolite in general industry and in the construction industry. The rulemaking record was reopened 7/18/86 to reconsider OSHA''s decision to regulate the substances in the same manner as asbestos.
