OSHA’s Hazard Communication Standard (HCS or Right-to-Know Rule) has been revised to align with requirements of the EU’s (European Union’s) Global Harmonization Standard (GHS). There are several deadlines from December 1, 2013 through June 1, 2016. The 2013 deadline was to train all employees on the new labels and Safety Data Sheets (SDS, formerly known as Material Safety Data Sheets or MSDS) that will be forthcoming with chemical products. There are nine hazard classifications and pictograms to universally communicate the hazards around the globe. The later deadlines concern revising your specific program and providing additional employee training for health or physical hazards.
