Revised hazard communication standard

  1. 1. The Revised HazardCommunication StandardThe Globally Harmonized System (GHS) forHazard Classification and LabelingPresented by Oswego County BOCES Safetyand Risk Department
  2. 2. Course Objectives• Inform employees of changes to the HazardCommunication Standard (HCS).• Discuss how the Global System ofClassification affects this change.• Provide employees with transitional trainingrequired by the revised HCS.• Alert employees to new hazardclassifications, labeling elements and SafetyData sheet requirements.
  3. 3. The New HazCom Standard• The Hazard Communication Standard, whichgives us the ‘Right to Know’ about chemicalswe use in the workplace has been revised.• Changes have brought the HCS into alignmentwith the Globally Harmonized System (GHS) ofClassification and Labeling of Chemicals.
  4. 4. About the GHS• The Global Harmonized System of Classification isa system for standardizing the classification andlabeling of chemicals around the world.• It is a logical and comprehensive approach for:– Defining health, physical and environmental hazardsof chemicals;– Creating classification processes that use availabledata on chemicals for comparison with the definedhazard criteria; and– Communicating hazard information, as well asprotective measures, on labels and Safety Data Sheets(SDS)
  5. 5. Why the GHS Affects Us!• Every year, the U.S. imports tens of thousands ofchemicals from around the globe.• In the past, chemical standards, classifications andlabels have varied from country to country.• Material safety data sheets (MSDS) lacked a standardformat.• Multiple types of labeling and classifying systemswere confusing to end-users.• These deficiencies put workers handling importedchemicals at greater risk.
  6. 6. In Other Words . . .In order to keep you safe, labels and safety datasheets all around the world will use the sameprecautionary statements, pictograms and signalwords to warn you about chemical hazards.
  7. 7. RTK vs. Right to Understand• The original the Hazard CommunicationStandard gave us the ‘Right to Know’ aboutthe chemicals we work with.• The new Globally Harmonized System givesworkers the ‘Right to Understand’ thatinformation better.
  8. 8. So what has Changed?• Labeling requirements:– The revised standard requires information to beconveyed with quick visual notations to alert theuser, providing immediate hazard recognition.– Labels must also provide handling instructions sothat users are informed on how to protectthemselves.• Safety Data Sheet format– Information is largely the same, but presented in aconsistent user-friendly 16 section format.
  9. 9. GHS Label Features• Labels now must have:1. Product identifiers2. Signal words3. Pictograms4. Hazard statements5. Precautionary statements6. Name, address and phone number of themanufacturer, distributor or importer
  10. 10. Product Identifiers• How the hazardous chemical is identified.– Chemical name– Chemical code number– Batch number.• The manufacturer, importer or distributermust decide on appropriate identifier ANDassure that it is on both the label and Section1 of the Safety Data Sheet.1
  11. 11. Signal Word• Used to indicate the relative level of severityof hazard and alert the reader to a potentialhazard 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
  12. 12. Pictograms• A pictogram is a symbol that is intended to conveyspecific information about the hazards of a chemical.• There are nine pictograms under the GHS.However, only eight pictograms are required under theHCS.• OSHA required pictograms must have all of thefollowing features:– Square set on end (diamond shaped)– Red frame– White background– Black hazard symbol3
  13. 13. Environment
  14. 14. Hazard Statements• Must describe the nature of a chemical’shazards, including the degree of hazard.• All applicable hazard statements must appearon the label.• Chemical users should always see the samestatement for the same hazards:– No matter what the chemical is.– Or, who produces it.4
  15. 15. Precautionary Statement• A phrase that describes recommendedprecautionary measures that should be taken for:– General precautions– Preventive precautions– Response precautions– Storage precautions– Disposal precautions• Each precautionary statement has analphanumeric code. (Click link below)• Explore Precautionary Statement and HazardCodes5
  16. 16. Contact Info• Name, address and phone number of thechemical manufacturer, distributor orimporter.6
  17. 17. Product IdentifiersSignal WordPictogramHazard StatementPrecautionary StatementName, Address, PhoneNew Label Example
  18. 18. Safety Data Sheets• The word ‘Material’ has been eliminated as aHazard Communication descriptor.• Safety Data Sheets (SDS) contain much of thesame info as MSDSs, but are now presented ina consistent user-friendly, 16 section format.Material
  19. 19. Section 1: Identification• An SDS must have the same product identifierused on the label and any other commonnames by which the substance is known.• Name, address and phone number of themanufacturer or importer, AND emergencyphone number.• Recommended use of the chemical with anyrestrictions on use.
  20. 20. Section 2: Hazard Identification• This section identifies the chemical hazardsand 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.
  21. 21. Section 3: Ingredients• Chemical name, common name andsynonyms.• CAS (Chemical Abstract Service) number andother unique identifiers.• Impurities and stabilizing additives.• For mixtures, chemical names andconcentrations.• Trade secret disclaimers.
  22. 22. Section 4: First Aid Measures• Necessary first-aid instructions by relevantroutes of exposure.• Description of important symptoms or effects,and whether they are acute or delayed.• Recommendations for immediate medical careand special treatment needed.
  23. 23. Section 5: Fire-fighting Measures• Recommendations for suitable extinguishingequipment.• Advice on specific hazards that develop fromthe chemical during the fire (e.g. hazardousbyproducts of combustion)• Recommendations on special protectiveequipment or precautions for firefighters.
  24. 24. Section 6: Accidental Release Measures• Pertains to appropriate responses tospills or leaks.– Personal precautions, such as removal ofignition sources and protectiveequipment needed to prevent exposureand contamination.– Emergency procedures, includinginstructions for evacuations andprotective clothing– Methods and materials used forcontainment.– Cleanup procedures.
  25. 25. Section 7: Handling and Storage• Precautions for safe handling, including:– Conditions for safe storage, including anyincompatibilities.– Advice on specific storage requirements (e.g.ventilation).– Minimizing releases into the environment.– Advice on general hygiene practices (e.g., workarea prohibitions on eating, drinking, etc.)
  26. 26. Section 8: Exposure Controls/PPE• Info on Permissible Exposure Limits(PELs), Threshold Limit Values (TLVs), etc.• Appropriate engineering controls .• Recommendations for personal protectiveequipment (PPE).• Special requirements for PPE (e.g., type ofglove material and breakthrough time of glovematerial).
  27. 27. Section 9: Physical and ChemicalProperties• Appearance• Odor• pH• Melting/freezing point• Boiling point and range• Flash point• Evaporation rate• Flammability• Flammable limits• Vapor pressure• Relative density• Solubility• Auto-ignitiontemperature• Decompositiontemperature• Viscosity
