Abstract:
OSHA proposes to amend its existing air contaminant standards [1910.
1000, Tables Z-1, Z-2, Z-3, and add a new Table Z-4. The amendments
reduce permissible exposure limits for approximately 100 substances
now listed in the "Z-tables," raise the permissible exposure limit
for 1 substance, set permissible exposure limits for 205 substances
currently not regulated by OSHA, add or change STEL's for 70
substances, and, as appropriate, set skin, short-term or ceiling
limits.

Abstract:
On June 7, 1988, Federal Register 53:20960, OSHA proposed to amend
its Air Contaminants standards, 29 CFR 1910.1000, Tables Z-1, Z-2,
and Z-3, and to add a Table Z-4. Notice is given that the Secretary
of Labor has changed the dates for submission of post-hearing

Notice that OSHA intends to file its final action in its pending
rulemaking [50 FR 50412, December 10, 1985] concerning Occupational
Exposure to Formaldehyde on December 2, 1987.

Abstract:
Revision of the Occupational Exposure to Formaldehyde standard
(1910.1048) by reducing the permissible exposure limits (PELs) from
3 parts formaldehyde per million parts of air (ppm) to 1 ppm as an
8-hour time-weighted average (TWA).

Abstract:
OSHA is extending the dates for submissions and comments and
changing the hearing dates on the proposal to amend the Air
Contaminants standard, 29 CFR 1910.1000. In addition, several
corrections are made to the proposal as it appeared in the Federal

Abstract:
OSHA is amending its existing Air Contaminants standard, [1910.
1000] including Tables Z-1, Z-2, and Z3. This amendment is limited
to making more protective 212 Permissible Exposure Limits (PEL)
listed in these Tables; setting new PEL's for 164 substances not
currently regulated by OSHA; and maintaining other PELs unchanged.
Changes include revision of the PEL; inclusion of Short Term
Exposure Limits (STEL) to complement 8 hour time weighted average
(TWA) limits; establishment of skin designation; and addition of
ceiling limits as appropriate.

Abstract:
This notice provides indexes to facilitate use of the Z-tables
published in the amendments to the Air Contaminants Standard (1910.

Abstract:
OSHA proposes to modify the existing provisions for controlling
employee exposures to toxic substances found in 1910.1000(e) and
1910. 134(a)(1). OSHA proposes to incorporate additional flexibility
in its methods of compliance requirements by more explicitly setting
forth the circumstances under which respiratory protection may be
used in lieu of engineering controls.
