2:00 p.m. – 4:30 p.m. Eastern Time

1:00 p.m. – 3:30 p.m. Central Time

12:00 p.m. – 2:30 p.m. Mountain Time

Attend as many as you’d like or attend all five and get one FREE!

This five session webinar series will provide attendees with an understanding and background of the criteria needed to classify hazardous products. Understanding the information presented on Safety Data Sheets is essential in responding to potentially hazardous products found in the workplace. After participating in this webinar series, attendees will have acquired the knowledge necessary to evaluate the information presented on SDS and give appropriate feedback to suppliers to improve the quality of information provided.

Session 1 – Introduction to GHS: Tips and Tricks for Evaluating SDS and Labels (October 2, 2018) – Safety Data Sheets are everywhere. Having a basic comprehension of SDS and hazard communication is no longer sufficient to understand and evaluate the hazards of chemicals. With the relatively new standards, information appearing on SDS has changed and the knowledge required to properly translate information on the SDS to workplace hazard control has increased.

After successful completion of Session 1, attendees will:

  • Be able to identify the key components of a compliant SDS
  • Know where to find the most important information on the SDS
  • Know how to provide appropriate feedback to suppliers
  • Know how to translate information on SDS to workplace hazard control
  • Be able to use SDS for workplace labeling

Session 2 – GHS: Physical Hazards (October 9, 2018)  – This session will review the physical hazard classes covered by the GHS including flammable gases, oxidizing liquids, corrosive to metals, etc. An overview of the data points needed for classification of physical hazards and an explanation on how to handle substances and mixtures will be presented. Label elements associated with each physical hazard will be reviewed.

After successful completion of Session 2, attendees will:

  • Understand the types of data used for each physical hazard classification
  • Know which questions to ask a supplier to better understand hazard classifications
  • Understand how GHS hazard classifications reflect relative hazards
  • Be able to identify label elements associated with each physical hazard
  • Be able to identify sources of independently available physical hazard data

Session 3 – GHS: Health Hazards (October 16, 2018) – This session will review the health hazard classes covered by the GHS. Acute toxicity, chronic health hazards such as reproductive toxicity and carcinogenicity, and low- and high-level health hazards will be discussed. An overview of the data points required for substance classification and the various mixture rules for all of the GHS health hazards will be presented. This session will also cover the nuances of health hazard classification that will allow participants to better understand the information conveyed on the SDS.

After successful completion of Session 3, attendees will:

  • Understand the different health hazards covered by the GHS
  • Understand the interaction between data points and classification
  • Know what data are required on the SDS to support health hazard classification
  • Understand how health hazard classifications are reflected in labeling
  • Be able to identify sources of independently available health hazard data

Session 4 – GHS: Environmental Hazards (October 23, 2018) – Optional in the U.S. and Canada, most international regulations have adopted the GHS Environmental Hazard Classification. This session will review the environmental hazard classes (hazardous to aquatic environment, hazardous to the ozone layer) covered by the GHS.

After successful completion of Session 4, attendees will:

  • Understand the different environmental hazards covered by the GHS
  • Know where to find environmental hazard data
  • Understand the interaction between GHS environmental hazard classification and transport
  • Understand the difference between acute and chronic environmental hazards

Session 5 – GHS Around the World (October 30, 2018) – Shipping to and receiving products from different regions of the world require knowledge of that region’s regulatory framework. Since the GHS has a building block approach, different countries may have implemented different hazard classes or hazard categories when incorporating GHS into their regulations. This session will provide an overview of where the GHS has been formally adopted and in what context. 

After successful completion of Session 5, attendees will:

  • Be able to identify the many countries where the GHS has been adopted
  • Understand the building block approach of GHS adoption
  • Understand the effect of GHS revisions on GHS adoption
  • Know the key deadlines for major country GHS adoption
