Introduction
1983: OSHA’s Mandates the Hazard Communication Standard - 1910.1200. Written Program Inventory List Labeling MSDS Employee Training & Information
2015, Major Overhaul to the Standard !

GHS Overview “Globally Harmonized System of the
Classification & Labeling of Chemicals and Safety Data Sheets”
United Nations guidance for a uniform (harmonized) hazard communication system• Initiated at the 1992 United Nations Conference on
Environment and Development (UNCED) Based on ”major” existing systems
• USA and Canadian systems for the workplace, workplace, consumers and pesticides
• European Union directives for classification and labeling of substances and preparations
• United Nations Recommendations on the Transport of Dangerous Goods.
6
OSHA rule
Major changes to the Hazard Communication Standards
Changed “hazard determination” to “hazard classification”
Changed “MSDS” to “SDS” Changed definitions to comply with GHS Labels for shipped containers must have
GHS information• Workplace labels may be GHS labels, or other
labels that identify the material and hazards that are as effective as the GHS labels.
Safety Data Sheets with 16 sections• Will include guidance for transportation
information and environmental hazards.
7
OSHA rule
Other OSHA standards will be affected where applicable (incorporated by reference)• New wording on warning signs for
asbestos and other health hazards.
• Affected standards include: HAZWOPER, Combustible and Flammable Liquids, Welding, Cutting and Brazing, Chemical Hygiene Plan, Permit-Required Confined Space Entry, etc.
8
GHS Overview Elements
Harmonized criteria for classifying substances and mixtures according to their health, environmental and physical hazards
Harmonized hazard communication elements, including requirements for labeling and safety data sheets.

GHS Overview
Justification Label requirements differ, requiring
multiple labels for the same product Hazard definitions are not consistent
• Toxicity, Flammability Over 100 diverse hazard
communication regulations for manufacturer’s products globally.• Regulatory compliance is complex and
costly• Barrier to international trade in chemicals

GHS Overview
Key Guiding Principles of the Harmonization Process
Protection will not be reduced
Will be based on intrinsic properties (hazards) of chemicals
All types of chemicals will be covered
13
I. GHS - Hazard Classification
Defined criteria are used to assign a hazard classification
Physical Hazards• 16 categories
Health Hazards• 10 categories
Environmental Hazards
Mixtures GHS classification guidance for when chemicals
are mixed for in house use or when exported.
GHS - Hazard Classification
Physical Hazards (16)
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
15
GHS - Hazard Classification
Health Hazards (10) 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
16
GHS - Hazard Classification
Hazardous to the Aquatic Environment -
Acute aquatic toxicity
Chronic aquatic toxicity• Bioaccumulation potential• Rapid degradability
Labels Symbols (hazard pictograms) with red
border• Examples:
17
II. GHS - LABELS
18
GHS - LABELS
Nine Symbols• Includes
“Environment”
Signal Words• “Danger” or “Warning”
Hazard Statements• Example: “Toxic if swallowed”
Other• Precautions, identification, supplier,
supplemental
19
GHS - LABELS
GHS Flammability Rating
1 = EXTREME ( FL. Class IA) “DANGER”
2 = MODERATE ( FL. Class IB) “DANGER”
3 = SLIGHT ( FL. Class IC / Comb. Class II) “WARNING”
4 = COMBUSTIBLE ( Comb. Class IIIA) “WARNING”
(No Rating for Combustible Class IIIB or lower)
20
GHS - Label Elements for Flammable Liquids
21
GHS - LABELS
NFPA - Flammability
4 = Will rapidly or completely vaporize at normal pressure and temperature, or is readily dispersed in air and will burn readily.
3 = Liquids and solids that can be ignited under almost all ambient conditions.
2 = Must be moderately heated or exposed to relatively high temperature before ignition can occur.
1 = Must be preheated before ignition can occur.
0 = Materials that will not burn.
The next slide shows the difference, very slight difference, in regards to the temperature change from the NFPA Classes to the GHS flammability ratings.
Example: where the Class IA and IB = 73.0 degrees F and under GHS the rating of 1 = 73.4 degrees F
The other temperature’s are about the same difference = 0.3 or 0.4 degrees F

III. GHS – Safety Data Sheets
16 headings
Similar to ISO, EU, and ANSI MSDS/SDS requirements
2828
OSHA MSDS format (old)
OSHA-174 (1989), 8 sections (non-mandatory)
1. Manufacturer information2. Hazard Ingredients/Identity Information 3. Physical/chemical properties4. Fire and Explosion Hazard Data 5. Reactivity Data 6. Health Hazard Data 7. Precautions for Safe Handling and Use 8. Control Measures
2929
ANSI MSDS format (GHS)
ANSI Z400.1-20041. Product and Company
Identification
2. Hazard Identification
3. Composition / Information On Ingredients
4. First Aid Measures
5. Fire Fighting Measures
6. Accidental Release Measures
7. Handling and Storage
8. Exposure Control / Personal Protection
9. Physical and Chemical Properties
10. Stability and Reactivity 11. Toxicological Information 12. Ecological Information 13. Disposal Considerations 14. Transport Information15. Regulatory Information 16. Other Information

EFFECTIVE DATES - OSHA rule
Federal & State Effective Completion Dates:
December 1, 2013: Employers must inform employees on the new label elements and SDS format.
June 1, 2015* Chemical manufacturers, importers, distributors and employers must comply with all modified provisions of this final rule.
Distributors may ship products labeled by manufacturers under the old system until December 1, 2015.
* This date coincides with the European Union implementation date for classification of mixtures.
June 1, 2016: Employer’s Must update alternative workplace labeling and hazard communication program as necessary, and provide additional employee training for newly identified physical or health hazards.
Transition Period Must Comply with either 29 CFR 1910.1200 (the final standard), or the current standard, or both for all chemical manufacturers, importers, distributors and employers.
31
The Impact on Safety and IH Professionals
Become familiar with the new system. Collect new SDS’s as provided by suppliers
and incorporate them into the existing MSDS system (or use a commercial service)
Get new GHS labels for “shipped containers”
Employers can use other systems for workplace labeling that are effective as the GHS labels.
Inform employees about new labels and SDS by December 1, 2013.
Impact on Chemical Manufacturers and
Distributors
Prepare and use new GHS compatible labels
Prepare and distribute new GHS compatible Safety Data Sheets
Commercial “authoring” firms are ready and willing to help
