What is GHS? - GHS (Globally Harmonized System) is a worldwide program developed by the United Nations which strives to provide a consistent, globally harmonized system of classifying chemical hazards on labels and safety data sheets through standardizing: how hazards are classified; hazard statements; hazard symbols; and hazard signal words. Why is GHS important? Chemicals are a fundamental part of the world economy. But currently, each country and each industry sector have a unique set of regulations. Not only can a lack of uniformity result in additional paperwork, but also misunderstood labels can lead to mishandling of chemicals. When global trade follows the same guidelines, we can be better assured of safe handling that protects both human health and the environment.
