Background – Scope and Development of the GHS as an International System Hazard Classification – Physical Hazards – Health Hazards – Environmental Hazards Hazard Communication Elements Labeling – Pictograms – Signal Words – Hazard Statements – Precautionary Statements Safety Data Sheets

A set of guidelines developed by the UN to ensure safe production, transport, handling, use and disposal of hazardous materials. (1992 Earth Summit) US (OSHA) officially adopted 3/26/12 as HazCom 2012 Target Audience - workers, employers, consumers, transport workers and emergency responders GHS is NOT a law or regulation. It is a logical and comprehensive system intended to harmonize definition, classification and communication of hazard.

Hazard Criteria, Class and Category Hazard Class – The nature of the physical or health hazard (environmental not in OSHA scope) Hazard Category – The division of the criteria within each hazard class – Categories compare hazard severity within the class

Explosives Flammable gases / Chemically Unstable Gases Flammable and Non- Flammable aerosols Oxidizing gases Gases under pressure Flammable liquids Flammable solids Self-reactive substances Pyrophoric liquids Pyrophoric solids Self-heating substances Substances which, in contact with water, emit flammable gases Oxidizing liquids Oxidizing solids Organic peroxides Corrosive to metals

Substances and Mixtures – generally same criteria Same criteria as current for transport classes (some additional categories added) Most hazard classes are divided into categories In general categories = transport packing groups

Acute toxicity Skin corrosion/ Irritation Serious eye damage/ Eye irritation Sensitization Germ cell mutagenicity Reproductive toxicity Carcinogenicity Specific target organ toxicity (STOT) – Single Exposure – Repeat Exposure Aspiration Toxicity

Currently only Aquatic Toxicity (acute and chronic) and Hazardous to the Ozone Layer

A composition that is intended to convey specific physical, health, and environmental hazard information (GHS hazard class and category) Eight pictograms are adopted in Hazcom 2012 – Red border, black symbol, white background

Unstable Explosives Explosives (Divisions ) Self-reactives (Type A and Type B with Flame) Organic Peroxides (Type A and Type B with Flame

Flammable Gases Flammable Aerosols Flammable Liquids (Categories 1-3) Flammable Solids Self-Reactives (Type B with bomb, Types C-F) Pyrophoric liquids and solids Self-heating substances Substances which in contact with water emit flammable gases Organic Peroxides (Type B with bomb, Types C-F)

Oxidizing Gases Oxidizing Liquids Oxidizing Solids

Compressed Gas Liquefied Gas Refrigerated Liquefied Gas Dissolved Gas

Corrosive to Metals (steel or aluminum >6.25 mm/year at 55C) Skin corrosion/ irritation – category 1 (A, B and C) Serious eye damage/irritation – Category 1

Acute Toxicity –Categories 1-3 (oral, inhalation or dermal routes)

Acute Toxicity – Category 4 (oral, inhalation or dermal routes) Skin Irritation/ Corrosion – Category 2 Serious Eye damage/ irritation – Category 2A Skin Sensitizer STOST (single exposure) – Category 3 (respiratory tract irritation, narcotic effects) Hazardous to the Ozone Layer

Respiratory Sensitizer Germ Cell Mutagenicity Carcinogenicity Toxic to Reproduction STOST (single exposure) – Categories 1-2 STOST (repeated exposure) – Categories 1-2 Aspiration Hazard

Acute hazards to the aquatic environment – Category 1 (Categories 2 and 3 no symbol or signal word) Chronic hazards to the aquatic environment – Categories 1 and 2 (Categories 3 and 4 no symbol or signal word)

A word used to indicate the relative level of severity of hazard and alert the reader to a potential hazard on the label “Danger” – used for the more severe hazards “Warning” – used for the less severe hazards

Hazard statement for each level of hazard (category) within each hazard class HAZARD: Category 1 highest 2 high 3 medium 4 low Example: Flammable liquids Category 1: Extremely flammable liquid and vapour Category 2: Highly flammable liquid and vapour Category 3: Flammable liquid and vapour Category 4: Combustible liquid Note: This is in reverse order to NMIS/NFPA

Precautionary statement means a phrase that describes recommended measures that should be taken to minimize or prevent adverse effects. There are 4 types of precautionary statements – Prevention – Response – Storage – Disposal The precautionary phrases are numbered in the GHS but not the Hazcom Standard.

Symbols (hazard pictograms) assigned to GHS hazard class and category Signal words (danger or warning) Hazard statements Precautionary statements Product identifier (ingredient disclosure) Supplier identification Supplemental information

Label elements located together on the label, tag or mark Pictograms must have red border wide enough to be visible and must not be blank Where a DOT label appears on a shipped container, the same OSHA pictogram shall not appear. Must not conflict with DOT regulations. Labels must be in English (other languages also permitted)

Chemical manufacturers and importers shall obtain or develop a safety data sheet for each hazardous chemical they produce or import. Employers shall have a safety data sheet in the workplace for each hazardous chemical which they use. Must be in English (additional languages permitted) If no relevant information for a sub-heading, must be marked to indicate no data SDS can cover similar mixtures
