CDC/NIOSH opened public comment period on five draft Skin Notation Profiles (Allyl alcohol, Formamide, Formic acid, Phenothiazine, Picric acid)

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.
