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

Hazard Communication In The GHS Document

• Ch. 1.4, Hazard Communication Labelling
• Target audiences
• comprehensibility
• translation
• standardization
• supplemental information
• updating
• confidential business information
• training

4
Labelling Target audiences

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

- Workplace - Consumers - Emergency
responders - Transport
5
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.

6
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.

7
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.

8
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.

Target audiences Needs

• Workplace including pesticides and
  pharmaceuticals
• Labels and Safety data sheets
• Consumers
• Labels
• Transport
• Labels, Placards, Transport documents (TREM Card)
• Emergency responders
• Labels, Placards

Pictograms prescribed by the GHS should have a
black symbol on a white background with a red
frame sufficiently wide to be clearly visible.
12
Labelling Pictograms Convey health, physical

Labelling

• Signal Words
• Danger or Warning
• are used to emphasis hazard and indicate the
  relative of severity of the hazard.

16
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

• Labellining
• 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 future as Annex 3 to Purple
book
21
Labelling

• Precautionary statements
• Measures to minimize or prevent adverse
  effects.
• Example (GHS Recommendation Annex 3)
• A3.3.3.3 Accident 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
24
Labelling

• Supplier Identification
• The name, address and telephone should be
  provided on the label.
• Supplemental Information
• non-harmonized information.

25
Label example
26
Precedence for the allocation of symbols (1)

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

27
Precedence for the allocation of symbols (2)

• For health hazards the following principles of
  precedence apply
• (a) if the Skull and crossbones applies,
• the Exclamation mark should not
  appear
• (b) if the Corrosive symbol applies,
• the Exclamation mark should not appear
• where it is used for skin or eye
  irritation
• (c) if the Health hazard symbol appears for
• respiratory sensitisation, the
  Exclamation
• mark should not appear where it is used
• for skin sensitisation or for skin or
  eye
• irritation.

28
Precedence for the allocation of symbols (3)

• Precedence for allocation of signal words If the
  signal word Danger applies, the signal word
  Warning should not appear.

GHSHazard Communication Safety Data Sheet
(SDS)
38
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 about hazards, and to obtain advice
  on safety precautions.

39
SDS Target audiences

• Workplace
• Consumers
• Emergency responders
• Transporters TREM CARD

40
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.

41
Cut-off values/Concentration limits for each
health and environmental hazard class

  similar to the ILO and ISO format, but sections 2
  and 3 reversed
