Preparing for the 2026 OSHA HazCom Deadline

The Occupational Safety and Health Administration’s (OSHA) revised Hazard Communication Standard (HCS), often referred to as “HazCom,” generally requires employers to update workplace chemical labels, written hazard communication programs, and employee training for newly identified hazards by November 20, 2026. As HazCom is one of the most heavily enforced OSHA rules, employers with employees who work with covered substances should ensure compliance.

Employers also must maintain a separate compliance timeline and checklist for chemical mixtures to avoid compliance gaps. Further, employers operating in jurisdictions with OSHA State Plans must verify specific compliance deadlines and requirements established by their state agencies, as they may differ from federal timelines.
