Introduction of GHS

What is GHS

1. Globally Harmonized System for Classification and Labeling of Chemicals, in short GHS. It is mainly aimed at chemical classification, labeling and content of material safety data sheet to enact globally harmonized standards. It is the important foundation of global chemical safety using.

2. Building Block Approach

3. GHS sets up the hazard classification criteria for substances and mixtures in the aspects of health, environment, and physical hazards,

4. GHS supplies the regulations of the important hazard communication element of the conciliation.


2)Material Safety Data Sheet, MSDS or SDS

5. Classification Categories

6. Parameter of GHS

GHS covers all hazardous chemicals. Because of products group and life cycle, the use of hazard communication element in GHS will be different, such as labeling and MSDS or SDS.

The development of GHS is exclusive of building a single test method or lining out the effect of health hazard by popularizing test.

Except animal experiment and clear in vitro test, human experience, epidemiology and clinical test are all applied to GHS system.

7. The Chinese guide of GHS

The Chinese guide of GHS is translated according to Purple Book, published in 2005 by the United Nations, ST/SG/AC.10/30/Rev. 1, ISBN 92-1-116927-5.


Classification of GHS

1. Harmonized hazard communication elements, including labels and MSDS/SDS

2. Unified classification standards of material and mixture, according to Health, Environment, and Physical Hazards.

a. Physical Hazards(16 classes)

Explosive-not classified

Gases under pressure-liquefied gas

Pyrophoric liquids-not classified

Oxidizing liquids-not classified

Flammable liquids-not classified

Flammable gases-not classified

Pyrophoric solids-not classified

Oxidizing solids-not classified

Flammable solids-not classified

Gases-not classified

Self-heating substances and mixtures-not classified

Organic peroxides-not classified

Flammable aerosols-1

Self-reactive substances and mixtures-not classified

Substances and mixtures, which in contact with water, emit flammable

Corrosive to metals-not classified


b. Health Hazards(10 classes)

Acute toxicity-not classified

Respiratory or skin sensitizer-not classified

Toxic to reproduction-Category 1B

Aspiration hazard-2

Skin corrosion / irritation-Category 2

Germ cell mutagenicity-Category 1B

Specific target organ toxicity - single exposure-Category 3(respiratory tract irritation, narcotic effects)


Serious eye damage / eye irritation-Category 2A

Carcinogenicity-Category 1B

Specific target organ toxicity - repeated exposure-Category 2(Blood, respiratory organs, nervous system)



c. Environmental Hazards(1class)

Acute hazards to the aquatic environment-not classified

Chronic hazard to the aquatic environment-not classified

Hazard to the ozone layer-not classified


Who does GHS apply to?

1. Consumers

2. Workers

3. Transport Workers

4. Emergency Responders


Why do we use GHS

1. To supply a global and easy understanding of hazard communication element, improving the protection of human health and environment.

2. To supply an accredited framework to countries which do not have any related system.

3. To reduce the requirements of chemicals test and assessment

4. To promote international trades between countries that has related chemical assessment.

5. To establish the basis of laboratory chemical management, and to promote the understanding of chemical hazard.

6. School strengthens laboratory safety and health management to protect people’s safety and health.


How to perform GHS?

1. The classification of hazard materials and mixture, physical hazards, health and environment hazards.

2. Labeling of hazard materials, such as schematism, warnings and hazard warning

3. MSDS/SDS of hazard materials, including 16 contents

4. Health and safety education and training to prevent chemical hazard

5. GHS application model

  On transport, the use of GHS is similar to transport requirement. It does not use warning and hazard captions which are required by GHS.

 On workplace, except environment hazard, all GHS elements should be accepted.

6. Marks of transport and workplace (laboratory)

 Outer packing: flammable liquid transport logo attaches on the box;

 Inner packing: GHS hazard warning mark attaches on the plastic bottles.
