What the HazCom 2024 update dates actually require

Employers must, as necessary, update workplace labels, the written Hazard Communication program and employee training for newly identified hazards: by 20 November 2026 for substances and by 19 May 2028 for mixtures (29 CFR 1910.1200(j)). Most everyday workplace products, such as cleaners, paints and disinfectants, are mixtures. The audit above checks each of those; both dates are explained here.
