What GHS?Logical and comprehensive approach to:

• Defining health, physical and environmental hazards of chemicals

• Creating classification processes that use available data on chemicals for comparison with the defined hazard criteria

• Communicating hazard information, as well as protective measures, on Labels and Safety Data Sheets (SDS)

The GHS itself is not a standard or a regulation.

The GHS document (referred to as “the purple book”) establishes agreed hazard classification and

communication provisions with explanatory

information on how to apply the system

What is GHS?

Why is GHS Necessary?

• The primary purpose of GHS is to reduce illness and injury caused by chemicals

• OSHA’s Hazard Communication Standard was published in 1983 • Resulted in a <42% in acute illness and

injuries from chemicals

Why is GHS Necessary?

• In the US alone there are many different classification systems used by various authorities.

This means that the same product can be non-hazardous or hazardous with

different labels and SDS

GHS BenefitsOverall

• Enhance the protection of human health and the environment

• Provide a recognized framework to develop regulations

• Facilitate international trade in chemicals whose hazards have been identified on an international basis

• Reduce the need for testing and evaluation against multiple classification systems

GHS Timeline in US

• December 1, 2013 train employees on the new label system

• June 1, 2015 comply with all modified provisions of the final rule, except:

Distributers may ship products labeled under the old system until Dec 1, 2015

• During transition may comply with 29CFR1910.1200 or current standard

GHS Major Elements

• Classification- Physical- Health- Environmental

• Communication- Labels- Safety Data Sheets

GHS Classification

• Definitions changed to provide specific criteria for classification: – health and physical hazards – Classifications of mixtures

• Specific Criteria will help ensure: – Evaluations of hazardous effects are

consistent across manufacturers – Labels and SDS’s are more accurate

GHS Classification

• Chemicals are first classified by one or more of three Hazard Classes: – Physical, Health or Environmental

• Each Hazard Class is divided onto hazard categories– Hazard categories may be further divided

into • divisions, types, groups etc..

Physical Hazards

• Explosives• Flammable gasses• Flammable aerosols• Oxidizing gasses• Gasses under pressure• Flammable liquids• Flammable solids• Self-reactive substances

Physical Hazards

• Pyrophoric liquids• Pyrophoric solids• Self heating substances• Substances which in contact with water

emit flammable gasses• Oxidizing liquids• Oxidizing solids• Organic peroxides• Corrosive to metal

Health Hazards

• Acute toxicity• Skin corrosion/irritation• Serious eye damage/eye irritation• Respiratory or skin sensitive• Germ cell mutantgency• Carcinogenicity• Reproductive toxicity

Health Hazards

• Target organ/systemic toxicity-single dose

• Target organ/systemic toxicity-repeated exposure

• Aspiration toxicity

Environmental Hazards

• Hazardous to aquatic environment– Acute aquatic toxicity– Chronic aquatic toxicity• Bioaccumulation• Rapid degradability

Hazard Communication

• Once the chemical has been classified, the hazard(s) MUST be communicated to target audiences

• The international mandate for the GHS included to development of a harmonized communication system including:– Labels– Safety Data Sheets (SDS)– Easily understandable symbols

Pictograms

• Pictogram is a communication:– Intended to convey specific information– 9 pictograms to convey:• Health hazards• Physical hazards• Environmental hazards

Pictograms

Health Hazard• Carcinogen• Mutagen• Respiratory sensitizer• Reproductive toxicity• Target organ toxicity• Aspiration toxicity

Pictograms

Flame• Flammables• Pryophorics• Self-Heating• Emits flammable gas• Self-reactive• Organic peroxides

Pictograms

Exclamation mark• Irritant (skin and eye)• Skin sensitizer• Acute toxicity (harmful)• Narcotic effects• Respiratory tract irritant• Hazardous to ozone

layer

Pictograms

Gas cylinder• Gas under pressure

Flame over circle•Oxidizers

Pictograms

Corrosion• Skin corrosion/burns• Eye damage• Corrosive to metals

Exploding bomb•Explosives•Self-reactives•Organic peroxides

PictogramsSkull and crossbones• Acute toxicity (fatal or

toxic)

Environment(non-mandatory)•Aquatic toxicity

Labels

Existing systems have labels that look different for the same product. Which leads to confusion, consumer uncertainty and the need for additional resources to maintain different systems

Label Elements• Signal word: is a word that typically

appears near the top of a label. Final rule requires the use of 1 of 2 signal words– DANGER– WARNING

• Hazard Statements describe the hazards associated with a chemical. – Intended to form a set of standardized

phrases about the hazards of chemical substances
