On March 26, 2012, the Federal Register published the final rule of the revised Hazard Communication Standards. These standards were revised to better protect employees from hazardous chemicals in the workplace environment as well as aligning the U.S. Hazard Communication standards with the United Nation’s Globally Harmonized System of classification and labeling of chemicals. Starting in 2016, this program will be fully implemented. Labs should replace their old MSDS sheets with the new SDS sheets that each manufacturer should be providing. If you do not have a copy of these new Safety Data Sheets, it is suggested you contact the manufacturer.
