HHS-OASH-2026-0397-5527 https://www.regulations.gov/comment/HHS-OASH-2026-0397-5527 inventhealth.care respectfully request The Department of HHS to extend the comment deadline by 30 days. The RFI requests evidence across distinct scientific, technical, public-health, and regulatory issues, including exposure measurement, existing safety standards, vulnerable populations, environmental effects, cumulative exposure, and federal research priorities. It expressly invites supporting studies, datasets, technical reports, and regulatory analyses. The current 30-day period is insufficient to permit interested parties to assemble and verify such materials and submit a technically grounded response. Thirty additional calendar days would permit respondents to verify sources, assess the relevance and limitations of technical evidence, consult appropriate subject-matter experts, and submit better-supported information. The requested extension would provide 60 calendar days in total from publication of the RFI, while leaving the Department free to continue reviewing materials already received. An extension would improve the quality of the record available to the Department before it uses these submissions to inform future recommendations or policies. The request is limited to 30 additional days and does not seek to delay the Department's review of comments already received. Respectfully Submitted, inventhealth.care
