What is it and how will it affect me?

By Sheryl Hoffmann

What is the ghs

What is the GHS?

The GHS is an acronym for The Globally Harmonized System of Classification and Labelling of Chemicals.

The GHS is a single internationally agreed system of classification and labelling of chemicals, which was developed under the auspices of the United Nations.

The GHS includes harmonised criteria for:

  • the classification of physical hazards (such as flammability),

  • health hazards (such as carcinogenicity) and

  • environmental hazards

How will i be affected

How will I be affected?

On 1 st january 2012

On 1st January 2012

  • The new Work Health and Safety Act, Regulations & Codes of Practice will come into effect, in all states in Australia.

  • All states will have the same legislation.

  • The Hazardous Substances part of this new legislation is based on GHS.

Why was the ghs developed

Why was the GHS Developed?

  • Different countries have different laws and regulations, as well as different definitions of what is hazardous, thus manufacturers need to produce different labels & MSDS’s for different countries. This is complex and costly and impacts on both protection for chemicals users and to trade.

What will be achieved

What will be achieved?

  • enhance the protection of people and the environment by providing an internationally comprehensive system for chemical hazard communication;

  • provide a recognised framework for those countries without an existing system;

  • reduce the need for duplicative testing and evaluation of chemicals; and

  • facilitate international trade in chemicals whose hazards have been properly assessed and identified on an international basis.

How is the ghs to be applied

Label information

Label Information

  • Product Identifier (eg name)

  • Proper Shipping name & UN Number (if Dangerous Good)

  • The name, address & phone number of the Australian importer or manufacturer

  • Identity & proportions (if a mixture)

  • Signal Word eg Danger or Warning

  • Hazard Statement

  • Hazard Pictogram

  • Precautionary Statements

  • Any other info eg first aid, emergency procedures

  • Expiry date of the chemical if applicable

Decanted substances

Decanted Substances

The label must be written in English and include the following:

  • the product identifier, and

  • a hazard pictogram and hazard statement that are consistent with the correct classification of the chemical.

Decanted label


Containers found without correct labelling

Containers found without correct labelling

If the product identifier of an unlabelled chemical is not known, this should be clearly marked on the container, for example by attaching a label to the container with the statement: Caution - Do Not Use - Unknown Substance.

Consumer products

Consumer Products

Original label on a consumer is sufficient if it is reasonably foreseeable that the hazardous chemical will be used in the workplace only:

  • in a quantity that is consistent with consumer household use, and

  • in a way that is consistent with consumer household use, and

  • in a way that is incidental to the nature of the work carried out by a worker using the chemical

7.1.23 Hazardous chemicals register

(1)A person conducting a business or undertaking at a workplace must maintain a register of hazardous chemicals used, handled or stored at the workplace.



(2)The register must include:

(a) a list of hazardous chemicals used, handled or stored; and

(b) the current safety data sheet for each chemical listed.



(3)The person must ensure that the register is readily available to:

(a) a worker involved in using, handling or storing a hazardous chemical; and

(b) anyone else who is likely to be affected by a hazardous chemical at the workplace.

Safety Data Sheets (SDS)

Code of Practice

Preparation of Safety Data Sheets for Hazardous Chemicals Code of Practice


ChemWatch can produce GHS Safety Data Sheet but WHS Regulations 7.1.21 clearly state the SDS must be obtained from the Australian manufacturer or importer.

A safety data sheet must include

A safety data sheet must include:

Section 1 - Identification: Product identifier and identity for the chemical;

Section 2 – Hazard(s) identification;

Section 3 - Composition and information on ingredients;

Section 4 - First-aid measures;

Section 5 - Fire-fighting measures;

Section 6 - Accidental release measures;

Section 7 - Handling and storage, including how the chemical may be safely used;

Section 8 - Exposure controls and personal protection;

A safety data sheet must include1

A safety data sheet must include:

  • Section 9 - Physical and chemical properties;

  • Section 10 - Stability and reactivity;

  • Section 11 - Toxicological information;

  • Section 12 - Ecological information;

  • Section 13 - Disposal considerations;

  • Section 14 - Transport information;

  • Section 15 - Regulatory information;

  • Section 16 - Any other relevant information.



Manufacturers and importers

  • Ensure that the chemical is correctly labelled.

  • However, you may not need to relabel a hazardous chemical if it is a consumer product that retains its original label, and the chemical is only used in workplaces in household quantities and in a way that is incidental to the nature of the work activities undertaken by any worker who uses the chemical.




  • Must not supply a hazardous chemical to a workplace if the supplier knows, or ought reasonably to know, that the chemical is not correctly labelled.



Person who is conducting a business or undertaking

  • Ensure that any hazardous chemical that is used, handled or stored at the workplace is correctly labelled, in accordance with Schedule 9 of the WHS Regulations, except where:

    • the hazardous chemical is a consumer product, retaining its original label and only used in workplaces in household quantities and in a way that is incidental to the nature of the work, or

    • a hazardous chemical is in transit.



Person who is conducting a business or undertaking

  • Ensure that a hazardous chemical is correctly labelled if the chemical is manufactured at the workplace; or transferred or decanted from the chemical’s original container at the workplace.

    NB: Manufacture includes the activities of packing, repacking, formulating, blending, mixing, making, remaking and synthesising.



Person who is conducting a business or undertaking

  • Ensure, so far as reasonably practicable, that containers are correctly labelled while holding a hazardous chemical.

  • Ensure that containers that are labelled for holding a hazardous chemical are used only for the use, handling or storage of the hazardous chemical.



Person who is conducting a business or undertaking

  • The above three duties do not apply if the hazardous chemical is used immediately after being put into the container and the container is thoroughly cleaned after the chemical has been used, handled or stored so it is in a condition it would be in if the container had never contained the chemical.

  • Ensure, so far as is reasonably practicable, that a hazardous chemical in pipe work is identified by a label, sign or another way on or near the pipe work.
