Introduction to HazCom
The OSHA Hazard Communication Standard (HazCom) is designed to ensure that information about chemical hazards and associated protective measures is disseminated to workers. This "Right to Know" standard requires employers to provide workers with effective information and training on hazardous chemicals in their work area. In 2026, OSHA’s adoption of GHS Revision 7 (HCS 2026) adds transition deadlines: manufacturers by May 2026, employers (labeling, training) by November 20, 2026—so keeping SDSs and labels current is more important than ever.
Key Requirements
The HazCom standard has four main requirements:
Written Hazard Communication Program: A written plan describing how your company will implement HazCom requirements
Safety Data Sheets (SDS): Detailed information sheets for each hazardous chemical
Container Labels: GHS-compliant labels on all chemical containers
Employee Training: Initial and ongoing training on chemical hazardsSDS Management Best Practices
Safety Data Sheets must be readily accessible to all employees during their work shift. Best practices include:
Maintain an up-to-date SDS for every hazardous chemical in the workplace
Ensure SDSs are available in a language workers can understand
Make SDSs accessible electronically and in print (as backup)
Review and update SDSs when new chemicals are introducedGHS Label Requirements
All hazardous chemical containers must have GHS-compliant labels including:
Product identifier (chemical name or code)
Signal word (Danger or Warning)
Hazard pictograms
Hazard statements (H-codes)
