Creating one global standard to classify and label hazardous chemicals has been a topic of international negotiations since the process began in Brazil in 1992. Now, the long-awaited and much-discussed Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is beginning to appear in the American workplace. December 1, 2013, was the deadline for the initial required employee training about the changes the GHS will bring to OSHA’s Hazard Communication Standard (HCS), which is used to ensure chemical safety in the workplace. The GHS will affect current HCS labeling requirements with the addition of new signal words, hazard and precautionary statements, and pictograms. One of the most noticeable changes is that material safety data sheets, or MSDS, will now be referred to as safety data sheets, or SDS.
