Classification of Chemical (GHS)
Globally Harmonized System of Classification and Labeling of Chemical (GHS) is a global system or method for the classification of chemical hazards (substances, mixtures, solutions, and alloys) and a way to communicate chemical hazards through Safety data sheets and labels (SDS).
The hazard classification of the GHS is divided into 17 physical hazards, 10 health hazards, and 2 environmental hazards.
Classification based on physical hazards
Can be divided into 17 types as follows:
2. Flammable Gases
4. Oxidizing Gases
5. Gases Under Pressure
6. Flammable Liquids
7. Flammable Solids
8. Self-Reactive Substances and Mixtures
9. Pyrophoric Liquids
10. Pyrophoric Solids
11. Self-Heating Substances and Mixtures
12. Substances and Mixtures which,
in Contact with Water, Emit Flammable Gases
13. Oxidizing Liquids
14. Oxidizing Solids
15. Organic Peroxides
16. Corrosive to Metals
17. Desensitized explosive
Classification based on health hazards
Can be divided into 10 types as follows:
1. Acute toxicity
2. Skin corrosion/irritation
3. Serious eye damage/eye irritation
4. Respiratory/skin sensitization
5. Germ cell mutagenicity
7. Reproductive toxicity
8. Specific target organ toxicity-single exposure
9. Specific target toxicity-repeated exposure
10. Aspiration hazard
Classification based on environmental hazards
Can be divided into 2 types as follows:
1. Hazardous to the aquatic environment
2. Hazardous to the ozone in the atmosphere
Hazardous Chemical Label (NFPA)
NFPA sign Indicates chemical hazardous in accordance with the NFPA (National Fire Protection Association) standards. It is a diamond shape sign which is divided into 4 sections, which are 4 adjacent diamonds with different colors as in the picture.
- – Red color section located at the top of the diamond indicates flammability.
- – Blue color section located on the left of the diamond indicates the level of health hazards of the chemicals.
- – Yellow color section on the right of the diamond indicates the level of chemical reactivity.
- – White color section at the bottom of the diamond is for additional important information such as water reactivity.
