GHS is the international system — developed by the United Nations — for classifying chemical hazards and standardizing labels, pictograms, and safety data sheet formats across countries. OSHA's Hazard Communication Standard, 29 CFR 1910.1200, often just called "HazCom," is the actual US federal regulation that adopted GHS and made it enforceable on American worksites. GHS is the framework; HazCom is the law. There's no separate "GHS training" requirement apart from HazCom — training on GHS labels and pictograms in the US satisfies 1910.1200, not some additional international rule.
The confusion is understandable, since both names get used for what's functionally the same training. Here's what each one actually is and how they fit together.
What GHS Itself Standardizes
The Globally Harmonized System of Classification and Labeling of Chemicals sets common rules — across the countries that adopt it — for:
- Classifying a chemical's physical, health, and environmental hazards using consistent criteria
- Standardized label elements: pictograms, signal words ("Danger" or "Warning"), and hazard statements
- A uniform 16-section safety data sheet (SDS) format
Before GHS, different countries (and sometimes different companies) classified and labeled the same chemical differently. GHS exists so a hazard pictogram means the same thing whether the container came from a US supplier or an overseas one.
What 1910.1200 Actually Requires
OSHA's own regulation states its purpose directly: 29 CFR 1910.1200(a)(1) says the standard's requirements "are intended to be consistent with the provisions of the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS), primarily Revision 7." In practice, 1910.1200 requires a US employer to maintain:
- A written hazard communication program
- Properly classified and labeled chemical containers, using GHS pictograms and signal words
- Accessible safety data sheets for every hazardous chemical on site
- Employee training on reading labels and SDSs and understanding the hazards they describe
HazCom applies in general industry, and — through 1926.59, which incorporates 1910.1200 by reference — on construction sites too. One regulation, one training obligation, covering both.
Why "GHS Training or HazCom Training" Is a False Choice
Because GHS's classification and labeling system is what 1910.1200 adopted, there's no separate international-rule training layer sitting on top of US HazCom training. When a US employer trains workers to recognize GHS pictograms, read a GHS-format SDS, and understand hazard statements, that training is satisfying 1910.1200 directly — not a parallel GHS requirement. Anyone asking "do I need GHS training or HazCom training" is really asking about the same training under two different names.

What Hazard Communication Training Actually Covers
Hazard Communication Training Online — GHS HazCom walks through the label elements and pictograms GHS standardizes, how to read a 16-section safety data sheet, and the "right to know" obligations 1910.1200 places on employers. It runs about 1 hour online, self-paced, with a certificate of completion the same day, valid for two years, and it's accepted by construction and general-industry employers nationwide as proof of HazCom training.
Anyone working around labeled chemical containers — paints, solvents, fuels, cleaning agents, adhesives — needs this training regardless of whether their job title has "chemical" anywhere in it. GHS HazCom training is written for that broad audience, not just lab or chemical-handling specialists.
Frequently Asked Questions
Q: Is GHS a US law?
No. GHS is an international framework developed by the United Nations. In the US, it becomes enforceable through OSHA's Hazard Communication Standard, 29 CFR 1910.1200, which adopted GHS's classification and labeling rules.
Q: Do I need separate GHS training and HazCom training?
No. They're the same training under two names. US HazCom training already covers the GHS pictograms, labels, and SDS format that 1910.1200 adopted — there's no additional international-rule training required on top of it.
Q: Does HazCom apply to construction sites, or just factories?
Both. 1910.1200 is written as a general-industry standard, but 29 CFR 1926.59 incorporates it by reference for construction, so the same labeling, SDS, and training requirements apply on job sites.
Q: What's a GHS pictogram?
A standardized hazard symbol inside a red diamond border — flame, skull and crossbones, corrosion, exclamation mark, and others — that means the same thing on any properly labeled container, regardless of manufacturer or country of origin.
Q: How long does GHS HazCom training take?
About 1 hour online, self-paced, with a certificate of completion the same day, valid for two years and verifiable online by its own code.
Q: Who actually needs this training?
Anyone who works around labeled hazardous chemicals on site — not just people who handle them directly. That includes crews using paints, solvents, fuels, adhesives, or cleaning agents as part of routine work.
