Globally Harmonized System for Classification & Labeling of Chemicals (GHS)

Keywords:  Substance and mixture classification, Safety Data Sheet content, Label elements, implementation updates

Brochure - Course available September 30 - October 2, 2023

Course Description and Objectives

This course is designed to be a comprehensive summary of the hazard classification and communication requirements in the Globally Harmonized System (GHS). Emphasis will be placed on:
  • Substance and mixtures classification criteria for physical, health, and environmental hazards,
    - Key concepts will be illustrated with examples,
  • Safety Data Sheet content,
  • Label elements, and
  • Implementation updates, including GHS Revision 10, as available, EU, CLP, OSHA HCS, and selected countries
The impact of the GHS on hazard communication requirements will be described. Specifically, the course will help students:
  • Understand the GHS, 
  • Understand the potential changes to their existing company products,
  • Develop a GHS compliance strategy, 
  • Keep informed about GHS implementation status, and facilitate informed comments to government agencies as the system is implemented.
  • Practice doing hands-on classification using provided mixtures examples.  Examples can also be used to assess electronic classification applications.

Intended Audience


This is considered an intermediate course. While there are no specific prerequisites, it is strongly recommended that participants have a working knowledge of EU and USA hazard communication principles.

Paul W. Brigandi

Paul W. Brigandi is a recognized expert in US and international hazard communication regulations.  The early part of Paul’s career was with Mobil Oil Corporation (20 years), where he was involved in a wide variety of research assignments.  He spent 10 years in the Product Safety group where he led multi-disciplinary teams, on the planning and implementation of global product safety compliance programs, not to mention writing thousands of SDS along the way.  While at Mobil Paul was a member of the OECD Expert Group on classification criteria for mixtures and he chaired both the BIAC to the OECD Expert Mixtures Group and the American Chemistry Council Global Harmonization Task Force. Paul retired from CGI Technologies and Solutions Inc. in 2020 where he led the design phase of projects which delivered commercial software supporting compliance with GHS hazard communication requirements and with the REACH Regulation. Paul also provided subject matter expertise to EPA in support of the design and development of the new electronic Chemical Data Reporting web tool (eCDR).  That successful project led to further development of a suite of web-based submission modules for electronic reporting under TSCA.  Paul also participated in a consortium of industry and software providers supporting the definition and implementation of an electronic data exchange standard for exposure scenario data throughout the supply chain under REACH.  He holds a BS in chemistry from Rutgers University.
