Respirator approval rules updated to recognize CSA Group certification alongside NIOSH

Plain-language summary · AI-assisted · not legal advice

Starting mid-2026, respirators provided to workers can be approved by the CSA Group (CSA) as an alternative to NIOSH approval, not just by NIOSH or a qualified-opinion-backed third party. The amendment adds CSA as a recognized certifying body in the respirator selection requirements and updates the filter designation codes for asbestos work (e.g., 'N-100' becomes 'N100' or 'CA-N100', and equivalent changes for R and P series filters). Employers who select and provide respirators will need to ensure their equipment meets the updated approval and filter labelling standards. Anyone currently specifying respirators for workers—particularly for asbestos exposure—should check that the filter designations in their written programs match the new codes.

Who this affects: employers with respiratory protection programs · occupational health and safety managers · industrial hygienists · contractors performing asbestos work · workers required to use respirators
