1. HAZARD COMMUNICATION

2. “Hazcom”
Purpose …”Ensure that the hazards of all chemicals produced or imported are evaluated, and that information concerning their hazards is transmitted to employers and employees.”

3. Development of a Worldwide System for Hazard Communication
The Globally Harmonized System (GHS) for Hazard Classification and Labeling
Development of a Worldwide System for Hazard Communication

4. What is the GHS?
A common set of guidelines to standardize the way chemical hazards are classified.
Target audiences include workers, consumers, transport workers, and emergency responders.
Provides the underlying infrastructure for establishment of national, comprehensive chemical safety programs.

5. Why is the GHS needed?
Countries with systems have different requirements for hazard definitions as well as information to be included on a label or material safety data sheet.
For example, a liquid may be considered flammable in one country, but not in another to which it is being shipped.

8. OSHA and GHS
OSHA’s part in this is a revision of the Hazard Communication Standard to align with the GHS. OSHA calls this
HazCom 2012

9. GHS Hazard Classification
Defined criteria are used to assign a hazard classification
