GHS, an acronym for Globally Harmonized System of Classification and Labeling of Chemicals, is a system aiming to standardize and harmonize the classification and labeling of chemicals. Although many countries follow regulatory systems for the safe handling and transport of chemicals through labels and safety data sheets, there is no standard approach. So while the formats are similar in different countries, the differences are significant enough to warrant different labeling and safety data sheets for the same product in different markets. With the gradual implementation of the GHS worldwide, countries have consistent and appropriate information on the chemicals they import or produce, and the infrastructure to control chemical exposures and protect people and the environment can be established in a comprehensive manner. This course introduces the GHS and explains how hazards are classified and communicated through the use of labels and safety data sheets. The course was developed and reviewed with subject matter support provided by certified subject matter experts and industry professionals. Please note, the course materials and content were current with the laws and regulations at the time of the last expert review, however, they may not reflect the most current legal developments. Nothing herein, or in the course materials, shall be construed as professional advice as to any particular situation with respect to compliance with legal statutes or requirements.
