Globally Harmonized System


The Health, Safety and Environment (HSE) resource library provides health and safety online courses and certificates for different industries to meet the demand in workplace occupational health and safety for a more skilled, competent, and safe workforce. This Library offers over 80 online courses and was designed to meet the different requirements of provincial and federal government legislation as well as to provide an incremental learning path leading towards three competency-based online certificates.


GHS stands for the Globally Harmonized System of Classification and Labelling of Chemicals. GHS is a system that defines and classifies the hazards of chemical products, and communicates health and safety information on labels and material safety data sheets (called Safety Data Sheets, or SDSs, in GHS). The goal is that the same set of rules for classifying hazards, and the same format and content for labels and safety data sheets (SDS) will be adopted and used around the world. An international team of hazard communication experts developed GHS.

Learning about GHS is part of the knowledge that you need to protect yourself and coworkers from hazardous products. The 16 Sections of a Safety Data Sheet (SDS) and the use of the SDS to identify hazards are taught so that you and your coworkers can work safely.


This is a three hour online course.
