Direct answer: Build and audit all sixteen headings as a connected document.
Headings 1–3 establish the product
Identification, hazard identification and composition connect the commercial product to its classification and disclosed ingredients.
Headings 4–8 support action
First aid, fire response, accidental release, handling, storage and exposure controls translate hazards into operational information.
Headings 9–11 preserve evidence
Properties, stability and toxicology should support or challenge the Section 2 result.
Headings 12–15 retain broader context
Ecology, disposal, transport and regulatory information follow the standardized order and require appropriate source ownership.
Heading 16 controls revision
The latest revision date should correspond to a documented internal change and approval record.
Practical example
Section 9 reports a low flash point while Section 2 and the bilingual label show no flammability conclusion. The release check blocks both language versions for technical review.
