GHS Chemical Labeling Guide for Industrial Sites
A labeling checklist for chemical managers and EHS teams.
Overview
The Globally Harmonized System (GHS) standardizes chemical hazard labels using pictograms, signal words, and standardized statements. Proper labels are required for hazardous chemical storage, handling, and shipping.
Required label elements
GHS labels must include product identifier, supplier information, signal word, hazard statements, precautionary statements, and applicable pictograms.
Common GHS pictograms
| Pictogram name | Hazard class | Typical example |
|---|---|---|
| Flame | Flammables | Solvents, fuels |
| Skull and crossbones | Acute toxicity | Highly toxic chemicals |
| Corrosion | Skin or metal corrosion | Acids, alkalis |
| Health hazard | Chronic toxicity | Carcinogens, respiratory sensitizers |
| Exclamation mark | Irritants | Mild acids, cleaners |
Labeling workflow
Verify labels on incoming containers, then ensure secondary containers are labeled before use. Store SDS documents with easy access for operators.
Common compliance gaps
Unlabeled spray bottles, faded hazard statements, and missing pictograms are frequent issues. Use durable materials and schedule periodic checks.
