One of the objectives of the work on the Globally Harmonized System (GHS) is the development of aharmonized communication system, including Labelling, Safety data sheets (SDS) and easily understandable symbols, based on classification criteria developed for the GHS.

Labelling : Target audiences

Labels communicate the hazard(s) according GHS classification to target audiences

-Workplace

- Consumers

- Emergency responders

- Transport

labelling target audiences 1
Labelling : Target audiences (1)
  • Workplace

Employers and workers need to know the hazards specific to the chemicals used and or handled in the workplace, as well as information about the specific protective measures required to avoid the adverse effects that might be caused by those hazards.

labelling target audiences 2
Labelling : Target audiences (2)

- Consumers

The label in most cases is likely to be the sole source of information readily

available to the consumer.

The label, therefore, will need to be sufficiently detailed and relevant to the use of the product.

labelling target audiences 3
Labelling : Target audiences (3)

- Emergency responders

Emergency responders need information on a range of levels.

To facilitate immediate responses, they need accurate, detailed and sufficiently clear information. This applies in the event of an accident during transportation, in storage facilities or at workplaces.

labelling target audiences 4

-Transport

The UN Recommendations on the Transport of Dangerous Goods, Model regulations, cater for a wide range of target audiences although transport workers and emergency responders are the principal ones. Others include employers, those who offer or accept dangerous goods for transport or load or unload packages of dangerous goods into or from transport vehicles, or freight containers.

  • Pictograms

Pictogram for flammable liquid in the UN Model Regulations (Symbol: Flame: Black or White background.)

Pictograms prescribed by the GHS should have a black symbol on a white background with a red frame sufficiently wide to be clearly visible.

Labelling
  • Signal Words:

“Danger”or“Warning”

are used to emphasis hazard and indicate the relative of severity of the hazard.

labelling1
Labelling
  • Hazard Statements:

Standard phrased assigned to a hazard class and category to specified the nature of the hazard.

Example : Acute Toxicity Oral ;

    • category 1

“Fatal if swallowed “

    • Category 2

“Fatal if swallowed ”

    • Category 3

“Toxic if swallowed”

    • Category 4

“Harmful if swallowed”

    • Category 5

“Maybe harmful if swallowed”

  • Precautionary Statements

GHS label should include appropriate precautionary information

GHS document contains examples of precautionary statements which can be used

The intent is to harmonize precautionary statements in the futureas Annex 3 to “Purple book”

labelling2
Labelling
  • Precautionary statements:

Measures to minimize or prevent adverse effects.

Example : (GHS Recommendation Annex 3)

A3.3.3.3Accident caused by ingestion

-If swallowed, seek medical advice immediately

and show this container or label.

-If swallowed, rinse mouth with water (only if the person is conscious).

-If swallowed, and the victim is conscious and

alert, induce vomiting immediately, as directed by medical personnel.

Labelling
  • Product Identifier

Name or number used for a hazardous product on a label or in the SDS.

Unique means by which the substance or mixture can be identified within the particular use setting

UN proper shipping name also to be used on the package when substance or mixture covered by the UN RTDG

labelling3
Labelling
  • Supplier Identification:

The name, address and telephone should be provided on the label.

  • Supplemental Information:

non-harmonized information.

precedence for the allocation of symbols 1
Precedence for the allocation of symbols (1)

For substances and mixtures covered bythe UN Recommendations on the Transport of Dangerous Goods, Model Regulations,the precedence of symbols for physical hazards should follow the rules ofthe UN Model Regulations.

precedence for the allocation of symbols 2
Precedence for the allocation of symbols (2)

For health hazards the following principles ofprecedence apply:

(a) if theSkull and crossbonesapplies,

theExclamation markshould not appear;

(b) if theCorrosive symbolapplies,

theExclamation markshould not appear

where it is used for skin or eye irritation;

(c) if theHealth hazard symbolappears for

respiratory sensitisation, theExclamation

markshould not appear where it is used

for skin sensitisation or for skin or eye

irritation.

role of the sds in the ghs
Role of the SDS in the GHS

SDS should provide comprehensive information about a chemical substance or mixture for use in workplace.

Both employers and workers use it as a source of information abouthazards, and to obtain advice on safety precautions.

target audiences
SDS Target audiences
  • Workplace
  • Consumers
  • Emergency responders
  • Transporters – TREM CARD
when is a sds required

When is a SDS required?

SDS should be produced for all substances and mixtures which meet the harmonized criteria under the GHS and for all mixtures which contain substances that meet the GHS criteria exceeding the cut-off limits for each

hazard class.

safety data sheets
