Pictogram Shape & Colour

  • Recommendation from ILO Group is that all pictograms should be in shape of a square set at a point (diamond)
  • For transport, pictograms will use the background and symbol colour specified in the UNRTDG Model regulations
  • For supply, pictograms will have a black symbol on a white background with a red frame

Some points on GHS Pictograms

  • UNRTDG will cover the transport area as they have been.
  • Competent authority may choose to give suppliers and employers discretion to use a black border for domestic use.
  • Competent authority may allow the use of UNRTDG pictograms in other use settings
slide13

Signal Word

  • “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”
slide14

Hazard Statements

  • A single harmonised hazard statement for each hazard category within each hazard class
  • e.g. Flammable liquid
    • - Category 1
    • “Extremely flammable liquid and vapour ”
    • - Category 2
    • “Highly flammable liquid and vapour”
    • - Category 3
    • “Flammable liquid and vapour”
    • - Category 4
    • “Combustible liquid”
hazard statements cont
Hazard Statements (cont.)

e.g. Oral Acute Toxicity

  • 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”

slide16

Precautionary Statements

  • GHS label should include appropriate precautionary information
  • The intent is to harmonise precautionary statements in the future
slide17

Examples of Precautionary Pictograms

From European Union (COUNCIL DIRECTIVE

92/58/EEC of 24 June 1992)

slide18

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

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
  • Competent authority rules for CBI take priority
slide21

Confidential Business Information

  • Competent authorities should establish appropriate mechanisms for CBI protection. CBI will not be harmonized under the GHS.
  • The provisions for CBI protection should not compromise the health and safety of users.
  • CBI claims should be limited to the names of chemicals and their concentrations in mixtures.
  • Mechanisms should be established for disclosure in emergency and non-emergency situations.
slide22

Other (Non-GHS) Information

  • Supplemental information
  • Competent authority may choose to specify where information should appear on the label or allow supplier discretion
  • Must not impede identification of GHS information

Physical Data

Boiling Point -The temperature at which a liquid turns to a vapour

slide40

Freezing Point

- Temperature at which the liquid form of a chemical will turn into the solid form

Melting Point

- Temperature at which the solid form of a chemical will turn into the liquid form

Vapour pressure

- The higher the vapour pressure,the more rapidly the material will change from liquid form to o vapour when released to the environment.

slide41

Vapour pressure

The amount of released harmful vapors in based on the chemical’s vapor pressure. The greater the vapor pressure, the greater the yield of hazardous vapors . Acetone will give off more vapors then gasoline. Sulfuric acid has a low vapor pressure and gives off little vapor.

slide42

Vapour density

- Density of a gas compared to the density of air

slide43

Specific gravity - density of a chemical compared to the density of water. If the specific gravity is less than one, the chemical will float on water. If the specific gravity is greater than one, the chemical will sink.

slide47

Water solubility of a chemical the quantity of a chemical that will mix with or dissolve in water. Helps to determine many of its toxic effects on living tissues / Chemicals that are very water soluble, lead to cellular injury.

slide48

Liquid - gas ratios. The volume of gas produced by the vaporization of a given volume of liquid . The volume of gas produced is always greater than the volume of liquid before vaporization.

slide49

Different chemicals have different expansion ratios. Liquified gases and cryogenics have the greatest

The expansion ratio of a chemical helps to determine the extent of hazard that the chemical poses.
