DANGERGHS Hazard Pictogram Quick Reference
All nine Globally Harmonised System pictograms with associated hazard classes, signal words, and regulatory requirements. Mandatory for chemical labels and Safety Data Sheets under OSHA HazCom 2012.
UN GHS Rev.9
OSHA 29 CFR 1910.1200
ISO 11014:2009 (SDS)
Signal Words
DANGER
Used for the more severe hazard categories (typically Category 1 and 2 of most hazard classes). Indicates a higher level of risk requiring immediate attention.
WARNING
Used for the less severe hazard categories (typically Category 3 and above). Indicates a lower level of risk compared to DANGER but still requires precaution.
Only one signal word appears on a label. If a substance warrants both DANGER and WARNING, only DANGER is used.

16Other Information — revision date, changes from previous version, H-statement full text
6 Required GHS Label Elements
Per OSHA 29 CFR 1910.1200(f), all six elements must appear on every shipped container label. Workplace labels must include at minimum a product identifier, words/pictograms/statements for hazards, and first-aid information.
Element 1
Product Identifier
Chemical name, code number, or batch number by which the hazardous chemical is known. Must match the identifier used in Section 1 of the SDS.
Element 2
Signal Word
Either DANGER (more severe) or WARNING (less severe). Only one signal word per label. If no hazard category requires one, no signal word is used.
Element 3
Hazard Statements
Standardised H-code phrases assigned to each hazard category. Example: H225 — Highly flammable liquid and vapour. All applicable H-statements must be listed.
Element 4
Precautionary Statements
Standardised P-code phrases describing measures to minimise or prevent adverse effects. Example: P210 — Keep away from heat, sparks, open flames, and hot surfaces.
Element 5
Pictogram(s)
One or more of GHS01–GHS09 pictograms within a red diamond border. All applicable pictograms must appear. GHS09 (Environmental) is voluntary under OSHA HazCom.
Element 6
Supplier Information
Name, address, and telephone number of the chemical manufacturer, importer, or other responsible party. Emergency contact number must be available 24 hours/day.
Notes & References
Regulatory note: OSHA HazCom 2012 (29 CFR 1910.1200) adopted GHS Rev.3 as its basis. Subsequent UN GHS revisions (currently Rev.9) may include additional hazard classes not yet incorporated into US federal law. Always verify current requirements with OSHA and your chemical supplier. GHS09 Environmental pictogram is not required by OSHA HazCom but may be required by other regulations (DOT, EPA). For EU requirements, refer to the CLP Regulation (EC) No 1272/2008.
