OSHA HazCom November 20, 2026: What Employers Should Check on Workplace and Secondary Container Labels

Short answer: Under OSHA's updated Hazard Communication Standard, employers have until November 20, 2026 to update workplace labels, their written hazard communication program and training, as needed, for chemical substances classified under the revised rule (29 CFR 1910.1200(j)(2)(ii)). For most plants, that means checking that secondary container and workplace labels match the current safety data sheet and stay readable where they are used.

What the November 20, 2026 date means for employers

OSHA updated its Hazard Communication Standard to align with GHS Revision 7. In January 2026, OSHA extended the compliance dates (FR Doc. 2026-00653). The current dates are:

Who	Substances	Mixtures
Manufacturers, importers, distributors	May 19, 2026	November 19, 2027
Employers	November 20, 2026	May 19, 2028

For employers, the November 20, 2026 date covers substances. By then, employers should update workplace labels, the written program and employee training as needed. Mixtures follow later, on May 19, 2028.

GHS is the Globally Harmonized System of Classification and Labeling of Chemicals. It standardizes how hazardous materials are classified and labeled, with common language and symbols for each hazard. The EPA, OSHA and the U.S. Department of Transportation have adopted GHS for use in the USA.

Workplace labels and secondary containers

Chemicals often leave the original shipping container. They get poured into drums, spray bottles, totes and smaller containers on the floor. Those secondary containers and workplace labels are the ones your team reads every day.

As updated labels and safety data sheets arrive from suppliers, your in-house labels can fall out of step. A drum label printed last year may no longer match the hazard wording on the current SDS.

Start with the SDS match

The first check is simple: does the label say the same thing as the current safety data sheet? A full GHS label carries six parts:

• Signal word: "Danger" for more severe hazards, "Warning" for less severe ones.
• Product name or identifiers.
• Hazard statements: phrases that describe the nature of the hazard and often the degree.
• Pictograms: red diamond symbols for health, physical and environmental hazards. A label may use one to five.
• Precautionary statements: prevention, response, storage or disposal precautions tied to each hazard.
• Manufacturer info: company name, address and phone.

Compare each part on your workplace labels with the current SDS. Your compliance team decides exactly what each workplace label must carry under your program.

Will the label stay readable in the real room?

A correct label only helps if people can read it. Labels on chemical containers deal with spills, cold, moisture, oil and handling. If the print rubs off or the label lifts, the information is gone.

When you pick label stock for workplace and secondary containers, think about where the container lives: cold storage, wet wash-down areas, oily machine zones or outdoor yards. Match the material and print method to that space.

For containers shipped over water, BS5609 applies. Labels that meet this standard are tested for harsh marine conditions. CIS's UV printed labels are certified for BS5609 Section 2 and 3 compliance, which means the media, text, coloring and images passed standardized testing for resistance to abrasion, UV exposure and sea water immersion, as well as other qualifications.

A quick checklist before November 20

• List the chemical substances in use and where secondary containers are filled.
• Pull the current SDS for each one.
• Check each workplace label against the SDS: signal word, identifiers, hazard statements, pictograms, precautionary statements.
• Flag labels that are faded, peeling or hard to read.
• Confirm your label stock and printing setup can produce the updated labels.
• Update your written hazard communication program as needed.
• Plan training for employees on any label changes.
• Note the May 19, 2028 date for mixtures so the next round is on the calendar.
