4 1. Introduction
5 What is the GHS? Objective Historical Background
6 What is the GHS? A common and coherent approach –To define and classify hazards –To communicate information on labels and safety data sheets (SDS) A simple and transparent method guided by Classification criteria Label requirements SDS requirements
7 What is the objective of the GHS? To enhance the protection of human health and the environment
8 Benefits of GHS Adoption Protection of humans and environment around the world will be enhanced. International trade in chemicals will be facilitated. An internationally maintained system will be made available to all nations. Avoidance of duplication of testing and evaluation of chemicals to determine their hazardous effects will be ensured.
9 Situation analysis of chemical Use Why is there a need for the GHS to address the issues of chemical safety?
10 (Insert pictures of modernized society or utilizing chemicals.)
11 (Insert pictures of disasters by chemicals.)
12 Magnitude of Chemical Use More than 27 million chemicals in the world CAS million work-related deaths every year ILO –1/4 caused by chemicals
13 Issues in Hazard information No one country has the ability to identify and regulate ALL hazardous chemicals and chemical products. Requirements for hazard definition, label or safety data sheet may differ from country to country.

16 Historical Background The Past That Defined GHS
17 A Chronology of Initiatives in Developing the GHS 1950s - United Nations issued Recommendations on the Transport of Dangerous Goods (UNRTDG). The GHS criteria for physical hazards based on UNRTDG.
18 A Chronology of Initiatives in Developing the GHS ILO adopted a Resolution concerning a Convention on safety in the use of chemicals at work ILO Convention 170 and Recommendation 177 on safety in the use of chemicals at work These instruments require countries to adopt a system for hazard classification and labelling UNRTDG
19 A Chronology of Initiatives in Developing the GHS ILO Resolution ILO Convention 170 and Recommendation United Nations Conference on the Environment and Development (UNCED) in Brazil: Established 6 programme areas in Chapter 19, Agenda 21 Chapter 19, Agenda 21, seeks to strengthen national and international efforts related to the environmentally sound management of chemicals UNRTDG

28 Target Audience of GHS Employers Workers Transport workers Consumers Emergency responders
29 Roles and Responsibilities of Major Stakeholders
30 Stakeholders Roles and Responsibilities Manufacturer or Supplier –To classify chemicals and make labels and SDSs Employer –To provide opportunities to educate and train workers on GHS –To ensure successful implementation of GHS in the workplace Worker –To understand value and implication of information on label and SDS and to improve attitudes and practices towards chemical management
31 Stakeholders Roles and Responsibilities Consumer –To understand the meaning of contents of a label Government –To harmonize the domestic regulations in order to implement GHS Academe, Scientific Institutions, Professional Organizations, etc. –To do hazard assessment, information dissemination, education and information campaign, etc.
32 Classification Criteria
33 Principles of Harmonized Classification System Classification is based on the hazards resulting from intrinsic properties of chemicals. Classification is based on currently acceptable and available data. –no test requirement in GHS
34 Classification Criteria for Hazards Physical Hazard Health Hazard Environmental Hazard
35 Physical Hazards
36 Harmonized Criteria for Physical Hazards Explosives Flammable gases Flammable aerosols Oxidizing gases Gases under pressure Flammable liquids Flammable solids Self-reactive substances and mixtures Pyrophoric liquids Pyrophoric solids Self-heating substances and mixtures Substances and mixtures which, in contact with water, emit flammable gases Oxidizing liquids Oxidizing solids Organic peroxide Compressed gas Corrosive to metal
37 Flammable Liquids CategoryCriteria 1Flash point < 23 o C and initial boiling point 35 o C 2Flash point 35 o C 3 Flash point 23 o C and 60 o C 4 Flash point > 60 o C and 93 o C
38 Health Hazards
39 Harmonized Criteria for Health Hazards Acute toxicity Skin corrosion/ irritation Serious eye damage/ eye irritation Respiratory or skin sensitization Germ cell mutagenicity Reproductive toxicity Carcinogenicity Specific target organ toxicity (single exposure) Specific target organ toxicity (repeated exposure) Aspiration hazard
40 Classification criteria for acute toxicity Acute toxicity estimate: LD 50 /LC 50 Category 1 Category 2 Category 3 Category 4 Category 5 Oral (mg/kg) See detailed criteria Dermal (mg/kg) Gases (ppm/4h) Vapours (mg/l/4h) Dusts and Mists (mg/l/4h) (LD 50 /LC 50 : lethal dose/lethal concentration causing death of 50% of test animals)
41 Classification Criteria for Carcinogens Category 1 Known or presumed carcinogen Category 2 Suspected carcinogen Limited evidence of human or animal carcinogenicity Subcategory 1A Known human carcinogen based on human evidence Subcategory 1B Presumed human carcinogen based on demonstrated animal carcinogenicity
42 Environmental Hazards
43 Harmonized Criteria for Environmental Hazards Hazardous to the aquatic environment
44 Classification Criteria for Substances Hazardous to Aquatic Environment Acute Category 1 Acute toxicity 1 mg/l Acute Category 2 Acute toxicity 1 but 10 mg/l Acute Category 3 Acute toxicity 10 but 100 mg/l Chronic Category 1 Acute toxicity <1mg/l and lack of rapid degradability and/or BCF > 500 (or, log Kow > 4) Chronic Category 2 Acute toxicity > 1 but < 10 mg/l and lack of rapid degradability and/or BCF > 500 (or, log Kow > 4) and unless chronic toxicity > 1 mg/l Chronic Category 3 Acute toxicity > 10 but < 100 mg/l and lack of rapid degradability and/or BCF > 500 (or, log Kow > 4) and unless chronic toxicity > 1 mg/l Chronic Category 4 No acute toxicity and lack of rapid degradability and BCF > 500 (or, log Kow > 4) and unless chronic toxicity >1 mg/l BCF: Bioconcentration Factor Kow: octanol/water partition coefficient
45 Classification of Mixtures
46 Classification of Mixtures Where test data are available for the complete mixture, the classification of the mixture will always be based on that data. Physical hazards: For physical hazards, test results of mixtures should be used for classification. However classification of Flammable Gases, Flammable Aerosols, Flammable Liquids and Oxidizing Gases may be determined by calculations in a specific cases.
47 Classification of mixtures (cont.) Health and Environmental Hazards: Where test data are not available for the mixture itself, then bridging principles included and explained in each specific chapter should be considered to see whether they permit classification of the mixture. When classifying an untested mixture based on the hazards of its ingredients, generic cut- off values or concentration limits for the classified ingredients of the mixture are used for several hazard classes in the GHS.
48 Hazard Communication
49 The sequence of chemical lifecycle
50 What is harmonized? Labels Safety Data Sheets (SDS)
51 Target Groups & Sectors Workplace including pesticides and pharmaceuticals –labels and safety data sheets Consumers –labels Transport –labels, placards, transport documents Emergency responders
53 Labels lThe Essential Tools 1.Symbols, Pictograms and colour 2.Signal words 3.Hazard statements 4.Precautionary statements and pictograms 5.Product identifiers/declaration of ingredients 6.Supplier identification
54 GHS Symbols Gas cylinderSkull & crossbones Exclamation Mark Health Hazard Environmental Hazard FlameFlame over circle Exploding bomb Corrosion
58 Signal Word Danger or Warning Used to emphasis hazard and to discriminate between hazard categories (level of hazard) Example: Acute toxicity Category 1, 2, 3 Danger, Category 4 Warning Danger Warning
59 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
60 Hazard Statements (cont.) e.g. 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
61 Precautionary Statements A precautionary statement means a phrase that describes recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure to hazardous product, or improper storage or handling of a hazardous product.
62 Precautionary Statements (cont.)
63 Examples of Precautionary Pictograms From European Union (COUNCIL DIRECTIVE 92/58/EEC of 24 June 1992)
64 Product Identifier 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, mutagenicity, carcinogenicity, reproductive toxicity, skin or respiratory sensitisation or Target Organ Toxicity UN proper shipping name also to be used on the package when substance or mixture covered by the UN RTDG
65 Other Points to Consider
66 Declaration of Ingredients Competent authorities should establish appropriate mechanisms for CBI (Confidential Business Information) protection. CBI will not be harmonized under the GHS. 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.
67 Supplementary Information Information on labels not harmonized under the GHS but are important may be placed on labels. Competent authorities determines if additional information are needed. Suppliers may choose to add supplementary information on their own initiative.
68 Category 1 Category 2 Category 3 Category 4 Category 5 Danger Fatal if swallowed Danger Fatal if swallowed Danger Toxic if swallowed Warning Harmful if Swallowed No Symbol Warning May be harmful if swallowed Allocation of Label Elements Example : Acute Toxicity (Oral)

74 Factors to Consider in the GHS Implementation
75 Points to implement GHS Harmonization Building Block Approach Translation into the local language Comprehensibility test Risk-based labelling
76 Harmonization Harmonization means establishing a common and coherent basis for chemical hazard classification and communication, from which the appropriate elements relevant to means of transport, consumer, worker and environment protection can be selected.
78 Building Block Approach Category 1Category 2Category 3Category 4Category 5 Danger Fatal if swallowed Danger Fatal if swallowed Danger Toxic if swallowed Warning Harmful if Swallowed No Symbol Warning May be harmful if swallowed Not required under the UNRTDG Example : Acute Toxicity (Oral)
79 Translation The GHS will be the basis for chemical management in the country or region. Without the GHS document in the local language, without GHS implementation. Translation should be harmonized in different sectors.
80 Comprehensibility Test Some information, like pictograms, on a GHS label may be very new to the public. Comprehensibility test on the GHS label or SDS can be recommended before implementing the GHS.
81 Risk-based Labelling All systems should use the GHS classification criteria based on hazard. However, competent authorities may authorize consumer labelling systems to provide information based on the likelihood of harm (risk-based labelling). Risk-based labelling maybe done only on chronic health effects (e.g. Specific Target Organ Toxicity following repeated exposure, reproductive toxicity and carcinogenicity).
82 Other Issues
83 Plans for International Implementation The GHS: will be a non-mandatory recommendation available to countries to implement, but once implemented in the local regulations, it will be mandatory. will be operational in every country before 2008.
84 ECOSOC GHS Structure UN ECOSOC Committee of Expert on TDG/GHS Sub-Committee of Experts on TDG Sub-Committee of Experts on GHS
85 Technical work concerning GHS Classification –Physical hazards TDG –Health hazard OECD –Environmental hazards OECD Supports to implement GHS in developing countries or countries with economy in transition UNITAR
86 Revision of GHS document The GHS document is regularly revised and updated to reflect national, regional and international experiences in implementing requirements into national, regional and international laws, as well as experiences of those doing the classification and labelling.
87 Updating of information Suppliers should respond to new and significant information they receive about a chemical hazard by updating the label and safety data sheet for that chemical.
