1. Globally Harmonized System Hazard Communication

2. Introduction Introduction Instructor Program
Hazard Communication Standard (HCS)/Globally Harmonized System (GHS)

3. HCS/GHS Terminal Objective
The students will be able to identify the presence and classification of hazardous materials through documentation and observation.

4. ENABLING OBJECTIVES The students will:
Identify the impact of Globally Harmonized System (GHS).

5. Background OSHA Final Rule Published March, 2012
Primary focus on 29CFR Hazard Communication Standard (HCS) (HazCom)
Changed many other OSHA standards
HAZWOPER Health Hazard definition changed to match Hazardous Communication Standard
Many of the specific chemical (“1000 series”) hazards defined, sign changes, and notification changes
Definition changes within flammable liquids and other standards

6. OSHA Hazardous Communication Standard (HCS)(29CFR1910.1200)
Ensure chemical safety in the workplace
Information about the identities and hazards of the chemicals must be available and understandable to workers.

7. OSHA Hazardous Communication Standard (HCS)(29CFR1910.1200)
OSHA Standard (HCS) requires the development and dissemination of information:
Chemical manufacturers and importers are required to
evaluate the hazards of the chemicals they produce or import
prepare labels and safety data sheets to convey the hazard information to their downstream customers;
Employers with hazardous chemicals in their workplaces must
have labels and safety data sheets for their exposed workers
train them to handle the chemicals appropriately.

8. OSHA Hazardous Communication Standard (HCS)(29CFR1910.1200)
Major changes to the Hazard Communication Standard (meet GHS)
Hazard classification: Provides specific criteria for classification of health and physical hazards, as well as classification of mixtures.
Labels: Chemical manufacturers and importers will be required to provide a label that includes a harmonized signal word, pictogram, and hazard statement for each hazard class and category. Precautionary statements also must be provided.
Materials Safety Data Sheets (MSDS) now Safety Data Sheets (SDS): Will now have a specified 16-section format.
Information and training: Employers are required to train workers by December 1, 2013 on the new labels elements and safety data sheets format to facilitate recognition and understanding.

9. Globally Harmonized System (GHS)
Hazard Communication Standard (HCS) now aligned with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS).
Provides a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets
Primary purpose of revised Standard is to improve the quality and consistency of hazard information in the workplace by providing easily understandable information on appropriate handling and safe use of hazardous chemicals.
Another purpose of update is to help reduce trade barriers
Additional Information:

10. GHS of Classification and Labeling of Chemicals
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)

11. GHS (cont.)
Attempt to create international standard for hazard identification systems
Differences exist internationally and also within nations

12. GHS (cont.)
For Instance, in the U.S. all of the following have different systems and definitions:
Consumer Product Safety Commission (CPSC)
Department of Transportation (DOT)
Environmental Protection Agency (EPA)
Occupational Safety and Health Administration (OSHA)

13. Flammable/Combustible Liquids - Now
In flashpoint - minimum temperature in degrees Fahrenheit at which a liquid will give off sufficient vapors to form an ignitable mixture with air
OSHA HCS
Flammable = Degrees
Combustible = deg.
OSHA/NFPA
Combustible = degrees EU
Extremely/Highly/Flammable = Deg.
DOT
Flammable = Degrees
Combustible = deg.
IMO
ICAO/IATA
Flammable = Degrees
CPSC
Flammable = Degrees
Combustible = deg.
ANSI Z129.1
Extremely Flammable = Deg.
Combustible = deg.
GHS
Everything actually called Flammable Liquid

17. Category Defines degree of hazard/danger for a type of substance.
Flammable Liquid – Category 1
Flash point < 23°C (73°F) and initial boiling point ≤ 35°C (95°F)

22. Signal Words
The signal word indicates the relative degree of severity a hazard.
The signal words used in the GHS are
“Danger”
for the more severe hazards
“Warning”
for the less severe hazards.
Some lower level hazard categories do not use signal words.
Only one signal word corresponding to the class of the most severe hazard should be used on a label.
