On 6/20/86 OSHA published revised standards governing occupational exposure to asbestos in general industry and construction. On 2/2/88, a U.S. Court of Appeals upheld the standard in most respects but remanded the case to OSHA on nine issues. OSHA issued its response on the first 3 remand issues on 12/10/90 (54 FR 52024). The present document constitutes OSHA''s response on the second group of remand issues: OSHA is (1) expandingits ban on workplace smoking and adding training requirements covering the availability of smoking control programs; (2) explaining how and why OSHA''s respirator requirements will result in employee risk being reduced below that remaining at the PEL; and (3) adding a requirement that employers assure that employees working in or contiguous to regulated areas comprehend required warning signs, and requiring that training programs specifically instruct employees about the content and presence of signs and labels. OSHA intends to publish a notice of proposed rulemaking by 2/27/90 covering the third (final) group of issues. Amendments to the standard will become effective May 7, 1990.
