The Revised Hazard Communication StandardThe Globally Harmonized System (GHS) for

Hazard Classification and Labeling

Page 2: Revised hazard communication standard

Course Objectives

• Inform employees of changes to the Hazard Communication Standard (HCS).

• Discuss how the Global System of Classification affects this change.

• Provide employees with transitional training required by the revised HCS.

• Alert employees to new hazard classifications, labeling elements and Safety Data sheet requirements.

Page 3: Revised hazard communication standard

The New HazCom Standard

• The Hazard Communication Standard, which gives us the ‘Right to Know’ about chemicals we use in the workplace has been revised.

• Changes have brought the HCS into alignment with the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals.

Page 4: Revised hazard communication standard

About the GHS

• The Global Harmonized System of Classification is a system for standardizing the classification and labeling of chemicals around the world.

• It is a logical and comprehensive approach for:– Defining health, physical and environmental hazards of

chemicals; – Creating classification processes that use available data on

chemicals for comparison with the defined hazard criteria; and

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

Page 5: Revised hazard communication standard

Why the GHS Affects Us!

• Every year, the U.S. imports tens of thousands of chemicals from around the globe.

• In the past, chemical standards, classifications and labels have varied from country to country.

• Material safety data sheets (MSDS) lacked a standard format.

• Multiple types of labeling and classifying systems were confusing to end-users.

• These deficiencies put workers handling imported chemicals at greater risk.

Page 7: Revised hazard communication standard

RTK vs. Right to Understand

• The original the Hazard Communication Standard gave us the ‘Right to Know’ about the chemicals we work with.

• The new Globally Harmonized System gives workers the ‘Right to Understand’ that information better.

Page 8: Revised hazard communication standard

So what has Changed?• Labeling requirements:– The revised standard requires information to be

conveyed with quick visual notations to alert the user, providing immediate hazard recognition.

– Labels must also provide handling instructions so that users are informed on how to protect themselves.

• Safety Data Sheet format– Information is largely the same, but presented in a

consistent user-friendly 16 section format.

Page 9: Revised hazard communication standard

GHS Label Features

• Labels now must have:1. Product identifiers2. Signal words3. Pictograms4. Hazard statements5. Precautionary statements6. Name, address and phone number of the

manufacturer, distributor or importer

Page 10: Revised hazard communication standard

Product Identifiers

• How the hazardous chemical is identified.– Chemical name– Chemical code number– Batch number.

• The manufacturer, importer or distributer must decide on appropriate identifier AND assure that it is on both the label and Section 1 of the Safety Data Sheet.

1

Page 11: Revised hazard communication standard

Signal Word

• Used to indicate the relative level of severity of hazard and alert the reader to a potential hazard on the label.

• There are only two (2) signal words:– DANGER is used for the more severe hazards.– WARNING is used for less severe hazards.

2

Page 12: Revised hazard communication standard

Pictograms

• A pictogram is a symbol that is intended to convey specific information about the hazards of a chemical.

• There are nine pictograms under the GHS. However, only eight pictograms are required under the HCS.

• OSHA required pictograms must have all of the following features:– Square set on end (diamond shaped)– Red frame– White background– Black hazard symbol

Environment

Page 14: Revised hazard communication standard

Hazard Statements

• Must describe the nature of a chemical’s hazards, including the degree of hazard.

• All applicable hazard statements must appear on the label.

• Chemical users should always see the same statement for the same hazards:– No matter what the chemical is.– Or, who produces it.

Page 15: Revised hazard communication standard

Precautionary Statement

• A phrase that describes recommended precautionary measures that should be taken for:– General precautions– Preventive precautions– Response precautions– Storage precautions– Disposal precautions

• Each precautionary statement has an alphanumeric code. (Click link below)

• Explore Precautionary Statement and Hazard Codes

Safety Data Sheets

• The word ‘Material’ has been eliminated as a Hazard Communication descriptor.

• Safety Data Sheets (SDS) contain much of the same info as MSDSs, but are now presented in a consistent user-friendly, 16 section format.

Material

Page 19: Revised hazard communication standard

Section 1: Identification

• An SDS must have the same product identifier used on the label and any other common names by which the substance is known.

• Name, address and phone number of the manufacturer or importer, AND emergency phone number.

• Recommended use of the chemical with any restrictions on use.

Page 20: Revised hazard communication standard

Section 2: Hazard Identification

• This section identifies the chemical hazards and the associated warning information.– Hazard classification (e.g., flammable).– Signal word (DANGER or WARNING).– Pictograms. – Precautionary statements.– Description of any unclassified hazards.– Percentages of hazardous mixture ingredients.

Page 21: Revised hazard communication standard

Section 3: Ingredients

• Chemical name, common name and synonyms.

• CAS (Chemical Abstract Service) number and other unique identifiers.

• Impurities and stabilizing additives.• For mixtures, chemical names and

concentrations.• Trade secret disclaimers.

Page 22: Revised hazard communication standard

Section 4: First Aid Measures

• Necessary first-aid instructions by relevant routes of exposure.

• Description of important symptoms or effects, and whether they are acute or delayed.

• Recommendations for immediate medical care and special treatment needed.

Page 24: Revised hazard communication standard

Section 6: Accidental Release Measures

• Pertains to appropriate responses to spills or leaks.– Personal precautions, such as removal of

ignition sources and protective equipment needed to prevent exposure and contamination.

– Emergency procedures, including instructions for evacuations and protective clothing

– Methods and materials used for containment.– Cleanup procedures.

Page 25: Revised hazard communication standard

Section 7: Handling and Storage

incompatibilities.– Advice on specific storage requirements (e.g.

ventilation).– Minimizing releases into the environment.– Advice on general hygiene practices (e.g., work

area prohibitions on eating, drinking, etc.)
