CDC/NIOSH published a Federal Register notice opening a docketed public comment process (CDC-2024-0085; NIOSH-153-F) for five draft NIOSH Skin Notation Profiles: allyl alcohol (CAS 107-18-6), formamide (CAS 75-12-7), formic acid (CAS 64-18-6), phenothiazine (CAS 92-84-2), and picric acid (CAS 88-89-1). For compliance and EHS teams, this signals potential forthcoming updates to NIOSH skin notation determinations used in occupational hazard communication and exposure control programs. The notice also highlights a methodological/documentation change in the draft profiles (removal of skin-to-inhalation dose (SI) ratio content from individual profile documents based on reviewer feedback) and explicitly requests stakeholder input on whether SI ratio information should be removed or included going forward.
CDC/NIOSH published a Federal Register notice requesting stakeholder comments on draft skin notation (SK) assignments and Draft Skin Notation Profiles for five chemicals: allyl alcohol, formamide, formic acid, phenothiazine, and picric acid. The notice also solicits feedback on a methodological/document-structure issue—removal of the skin-to-inhalation dose (SI) ratio information from individual profile documents—and indicates drafts will be finalized after addressing comments. Compliance/IH teams may want to review draft SK assignments and anticipate potential updates to internal dermal hazard communication, PPE selection rationales, and chemical risk assessments that reference NIOSH skin notation rationale documents.
