Globally Harmonized System of Classification and Labelling of

Chemicals

Hazard Communication in the GHS




» Fifth level



Labels and label elements

Safety Data Sheets




» Fifth level


Hazard Communication background

Task undertaken by the ILO tri-partite group (governments, labor and industry)

To develop an internationally-comprehensible system for hazard communication

Hazard communication elements for each agreed classification category




» Fifth level


Harmonization of the major international systems

Transport and supply (as far as possible)

Three major systems (US, Canada, European Union)

Others (Japan, China, Australia, Brazil, etc.)




» Fifth level


Target groups/ sectors/needs

Workplace including pesticides and pharmaceuticals - labels and safety data sheets

Consumers - labels

Transport - labels, placards, transport documents

Emergency responders - labels, placards




» Fifth level


Labels

The ILO Work Group identified about 35 different types of information that are required on labels by different systems.

Key information elements harmonized

Additional harmonization in future




» Fifth level


Key harmonized label elements

Symbols/pictograms

Signal Words

Hazard Statements

Product identifier/ingredient disclosure

[Precautionary information]




» Fifth level


Symbols/pictograms in the GHS

Same symbols (where there is commonality) and pictogram shape for transport and supply (square on point)

Transport pictograms will use the background and symbol colour specified in the UN RTDG Model regulations

For supply, pictograms will contain a black symbol on a white background with a red frame

5.1




» Fifth level


Supply symbols in the GHS Fish and tree symbol for environmental hazard (under

consideration for transport)

Exclamation mark for “low level” health hazard

New symbol for chronic health hazards




» Fifth level


Transport pictograms

» Fifth level


GHS pictograms

!




» Fifth level


Signal words“Danger” or “Warning”

Used to emphasis hazard and to discriminate between hazard categories (level of hazard)

e.g. Acute toxicity category 1 will require “Danger”, category 4 will require “Warning”




» Fifth level


Hazard statements A single harmonised hazard statement for each hazard

category within each hazard class

e.g.Category 1 Flammable liquid

“extremely flammable liquid and vapour”Category 2

“Highly flammable liquid and vapour”Category 3 - “flammable liquid and vapour”Category 4 - “combustible liquid”




» Fifth level


Precautionary statements

GHS label should include appropriate precautionary information

GHS document contains examples of precautionary statements which can be used




» Fifth level


Precautionary statements

SCE GHS Intersessional Group on harmonisation of precautionary statements

ICSC compilers guide is likely to be used as a major source for selection of PS (will be harmonised with GHS)

Hierarchy for PS




» Fifth level


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




» Fifth level


Declaration of ingredients Substances

chemical identity (name as determined by IUPAC, ISO, CAS or technical name)

Mixtures chemical identities of all ingredients contributing to acute

toxicity, skin or eye corrosion, germ cell mutagenicity, carcinogenicity, reproductive toxicity, skin or respiratory sensitisation or TOST




» Fifth level


Confidential business information National authorities to establish appropriate mechanisms

for CBI

Competent authority rules for CBI take priority in relation to ingredient declaration

Principles established, particularly “right-to-know”




» Fifth level


What will GHS label look like?(Acute toxicity oral, cat.2)

Product identifier: “GREAT-STUFF”contains X, Y, Z

Symbol or

Signal Word

Hazard Statement: “Fatal if swallowed”

Precautionary information




» Fifth level


Examples of arrangements of GHS elements (GHS, Annex 6)

A6.1.1 Label for large receptacle (200 litre drum) for transport, emergency response and workplace audiences

UN 2920 2-methyl tetramethylenexxxxxCorrosive liquid, flammable, N.O.S. Danger(2-methyl tetramethylenexxxxx) Causes severe skin burns and

serious eye damageHighly flammable liquid and vapourAvoid contact with skin and eyesKeep away from heat and ignition sources

First aid:For skin contact, remove contaminated clothing and wash affected area thoroughly with

water. If irritation develops, seek medical attention.For eye contact, immediately flush eyes with flowing water for at least 15 minutes and seek

medical attention.GHS Example Company, Akron, NWT, Canada. Telephone (888) 888-8888




» Fifth level


Other information (Non- GHS)

Supplemental information

National authority may choose to specify where information should appear on the label or allow supplier discretion

Must not impede identification of GHS information




» Fifth level



Labels and label elements

Safety Data Sheets




» Fifth level


Safety Data Sheets

Primarily workplace use

16 heading format agreed

Minimum additional information specified, where applicable or available, under the relevant headings




» Fifth level


Safety Data Sheets (cont’d)

Potential for overlap with ISO 11 014-1:1994, currently being updated

Need for consistency between ISO and GHS requirements

SCE GHS Intersessional Group to further develop GHS guidance on SDS




» Fifth level


Other issues Training

Comprehensibility

Consumer product labelling based on likelihood of injury Competent authority discretion Annex 4 to GHS provides guidance




» Fifth level


Dual labelling for transport and supply

Concern about GHS supply pictograms appearing on single packages which also are labelled with UN pictograms, potential for confusion, e.g. in postal sorting offices

Study carried out by US

Conclusion: clearer guidance needed in GHS to ensure differentiation between transport-regulated classes and other classes




» Fifth level


SCE GHS Intersessional Group on labelling

Development of additional guidance to clarify labelling provisions and to ensure consistent implementation of the GHS Size and placement of the GHS pictograms

Ensure clear distinction between label elements for transport and those for other sectors

Precedence of hazard in application of GHS pictograms




» Fifth level


Competent authority options

Updating labels for new information, CA to specify time limit

Review of labels content, CA to specify review period required

GHS label pictograms, permission to use a black, not red, frame




» Fifth level


Competent authority options (cont’d)

Hazard Statements, CA may specify sequence on label

Label format, CA may specify format

Use of colour on label, CA may stipulate own provisions

Workplace labelling, CA may allow alternative means




» Fifth level


Conclusions

Difficult, long-term process, much work still to be done By UN SCE GHS Subcommittee By countries when GHS is introduced

Significant benefits more logical system economic

Will be easier for small businesses to comply and will improve comprehensibility for users
