OSHA reopens comment period for 13 proposed rules

OSHA has reopened the comment period for 13 chemical-specific proposed rules. The August 21 deadline provides the public 30 days to comment on recommendations made by OSHA’s Advisory Committee on Construction Safety and Health (ACCSH). The rules are:

• 1,2-dibromo-3-chloropropane
• 1, 3- Butadiene
• 13 Carcinogens (4- Nitrobiphenyl, etc.)
• Acrylonitrile
• Asbestos
• Cadmium
• Ethylene Oxide
• Formaldehyde
• Inorganic Arsenic
• Lead
• Methylene Chloride
• Methylenedianiline
• Vinyl Chloride

The proposed rules were originally published in the Federal Register on July 1, 2025. At that time, OSHA was in the process of appointing members to ACCSH. The agency stated that it would present the proposed rules to ACCSH once that process was complete and would allow the public time to provide comments on the recommendations.
