New Brunswick begins full enforcement of amended rules
WorkSafeNB began full enforcement of the General Regulation 91-191 amendments on January 9, 2025. The checked regulation uses the 2016 ACGIH edition for its exposure-limit definition, subject to explicit exceptions.
January 9, 2025 is an enforcement milestone. It does not establish the original commencement date of every amendment or the first adoption of the 2016 edition.
