The document discusses the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). GHS aims to standardize chemical hazard classification and communication globally. It establishes internationally understood definitions for chemical hazards and standardized labels, safety data sheets and other forms of hazard communication. The document outlines the key components of GHS including physical and health hazard classification criteria, GHS label elements, and guidance for implementation of GHS in workplaces.
HAZCOM
- 2. GHS • Globally Harmonized System of Classification & Labeling of Chemicals
- 3. GHS • A system for standardizing and harmonizing the classification and labeling of chemicals • Defines health, physical and environmental hazards of chemicals • Communicates hazard information, as well as protective measures, on labels and Safety Data Sheets (SDS).
- 4. Current Systems • Differences in systems within different countries and within different regulatory agencies within the same government leads to inconsistent protection for those potentially exposed to the chemicals as well as creating extensive regulatory burdens on companies producing chemicals
- 5. GHS • The GHS itself is not a regulation or a standard • Establishes agreed hazard classification and communication provisions with explanatory information on how to apply the system
- 6. Why Was GHS Developed? • To provide sound management of chemicals that includes a system through which chemical hazards are identified and communicated to all who are potentially exposed
- 7. International Mandate •Adopted in the 1992 United Nations Conference on Environment and Development (UNCED), often called the "Earth Summit". •It was recognized that an internationally harmonized approach to classification and labeling would provide the foundation for all countries to develop comprehensive national programs to ensure the safe use of chemicals.
- 8. GHS History • GHS formally adopted by the UN Committee of Experts - The Transport of Dangerous Goods and GHS in December 2002 • OSHA ANPR on GHS 2006 • OSHA NPRM on GHS 2009
- 9. GHS History • OSHA revised the Hazard Communication Standard, aligning it with the GHS March 26, 2012 • Rule effective 60 days after publication in the Federal Register • Estimated to prevent 43 fatalities and 521 injuries & illnesses annually
- 10. December 1, 2013 – • Employers must train employees on how to read GHS formatted labels and SDS’s. • Changes to labels are probably more substantial, however, employees need to understand where to find information on the SDS. Implementation
- 11. Implementation 2013 – 2015 On an Ongoing Basis – • Employers should replace existing MSDSs with new SDSs as they become available.
- 12. Implementation June 1, 2015– • Chemical manufacturers and distributors should have completed their reclassification of chemicals and be shipping GHS formatted SDS and labels with their shipments.
- 13. Implementation December 1, 2015 – • Distributors have an additional 6 months beyond the June 1, 2015 date to pass along manufacturer labels and SDSs in the older formats. However, beyond December 1, 2015, all MSDSs and labels in the U.S. should be in compliance with HazCom 2012 provisions.
- 14. Implementation June 1, 2016 – • Employers should be fully compliant with HazCom 2012. That includes making any necessary updates to their HazCom program, training employees on any newly identified chemical hazards (identification of new hazards is likely during the reclassification process chemical manufacturers undertake), and updating SDS libraries and secondary labels.
- 15. Application of GHS •Enhance the protection of human health and the environment by providing an internationally comprehensible system •Provide a recognized framework to develop regulations for those countries without existing systems •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
- 16. Overall Benefits of GHS • To ensure that employers, employees and the public are provided with adequate, practical, reliable and comprehensible information on the hazards of chemicals, so that they can take effective preventive and protective measure for their health and safety
- 17. Benefits to Workers/Public • Improved safety for workers and others through consistent and simplified communications on chemical hazards and practices to follow for safe handling and use, • Greater awareness of hazards, resulting in safer use of chemicals in the workplace and in the home
- 18. GHS & Existing Regulations • The specific hazard criteria, classification processes, label elements and SDS requirements within an existing regulation will need to be modified to be consistent with the harmonized elements of the GHS • ALL existing hazard communication systems will need to be changed in order to apply the GHS
- 19. Classification • Classification is the starting point for hazard communication • Involves the identification of the hazard(s) of a chemical or mixture by assigning a category of hazard/danger using defined criteria
- 20. Hazard Classes • 16 classes of physical hazards • 10 classes of health hazards • 3 classes of environmental hazards
- 21. GHS Physical Hazards • Explosives • Flammable Gases • 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
- 22. GHS Health Hazards • Acute Toxicity • Skin Corrosion/Irritation • Serious Eye Damage/Eye Irritation • Respiratory or Skin Sensitization • Germ Cell Mutagenicity • Carcinogenicity • Reproductive Toxicology • Target Organ Systemic Toxicity - Single Exposure • Target Organ Systemic Toxicity - Repeated Exposure • Aspiration Toxicity
- 23. GHS Environmental Hazards • Hazardous to the Aquatic Environment • Acute aquatic toxicity • Chronic aquatic toxicity • Bioaccumulation potential • Rapid degradability
- 24. GHS Hazard Communication • Once a chemical has been classified, the hazard(s) must be communicated to target audiences • Labels and Safety Data Sheets are the main tools for chemical hazard communication
- 25. GHS Label Elements • Product Identifier • Signal Word (Danger, Warning) • Hazard Statement (for each hazard class and category) • Pictogram(s) • Precautionary Statement (for each hazard class and category) • Name, Address and Tele. # of chemical manufacturer
- 26. Signal Words "Danger" or "Warning" are used to emphasize hazards and indicate the relative level of severity of the hazard, assigned to a GHS hazard class and category. • "Danger" for the more severe hazards • "Warning" for the less severe hazards.
- 27. Hazard Statements • Hazard statements are standardized and assigned phrases that describe the hazard(s) as determined by hazard classification
- 28. Hazard Statement Examples • “Causes eye irritation” • “Toxic if inhaled” • “Flammable aerosol” • “May cause cancer” • “May cause respiratory irritation” • “Harmful to aquatic life” • “Contains gas under pressure; may explode if heated”
- 29. Symbols/Pictograms • Convey health, physical and environmental hazard information, assigned to a GHS hazard class and category. • The GHS symbols have been incorporated into pictograms for use on the GHS label • Pictograms will have a black symbol on a white background with a red diamond frame
- 30. Health Hazard Carcinogen Mutagenicity Reproductive Toxicity Respiratory Sensitizer Target Organ Toxicity Aspiration Toxicity
- 32. Exclamation Mark Irritant (skin and eye) Skin Sensitizer Acute Toxicity Narcotic Effects Respiratory Tract Irritant Hazardous to Ozone Layer (Non-Mandatory)
- 33. Skull & Crossbones Acute toxicity (fatal or toxic)
- 35. Corrosion Skin Corrosion/Burns Eye Damage Corrosive to Metals

- 47. Secondary Containers • Employers must ensure that each container of hazardous chemicals in the workplace is labeled, tagged, or marked with either the information specified under (i) through (v) for labels on shipped containers
- 48. Secondary Containers • (i) Product identifier; • (ii) Signal word; • (iii) Hazard statement(s); • (iv) Pictogram(s); • (v) Precautionary statement(s); OR
- 49. Secondary Containers •Product identifier and words, pictures, symbols, or combination thereof, which provide at least general information regarding the hazards of the chemicals, and which, in conjunction with the other information immediately available to employees under the hazard communication program, will provide employees with the specific information regarding the physical and health hazards of the hazardous chemical.
- 50. Why the switch from MSDS to SDS? • Under the HazCom 2012, the MSDS will be replaced with a Safety Data Sheet (SDS). • Before the HazCom 2012, there were several acceptable MSDS formats. OSHA’s adoption of Global Harmonization Standards (GHS) requires the use of a single format. • All SDS will have 16 sections that appear in a specific order.

- 69. Section 16 - Other information Indicates when the SDS was prepared or when the last known revision was made. Other useful information also may be included here
- 70. Will the change require that both and MSDS and an SDS be kept for the same product? • For compliance with the new OSHA HazCom 2012 regulatory requirements, maintaining both an MSDS and a SDS for the same chemical is not necessary. • As the SDS becomes available for individual products, they will replace the existing MSDSs. • Although there is no requirement to keep the older MSDS once it is replaced with an SDS, a good management practice would be to keep an electronic copy on file, especially if existing stocks of the chemical were purchased under the older MSDS.
- 71. Key Points to Remember •It is essential to have complete and accurate information about the substances you use •The SDS helps prevent accidents and exposures •Always consult the SDS for the substances you use on the job.
