GHS Hazard Communication: Pictograms of Hazards

In 2012, OSHA incorporated the Global Harmonized System (GHS) into the existing Hazard Communication regulation (1910.1200). The intent behind its addition was: (1) to provide employers and employees with additional tools to recognize chemical hazards and (2) to allow the USA to import/export products with uniform labeling and safety data sheets. In General Industry, Hazard Communication (HazCom) has been the most frequently cited law for over ten years. With the addition of hazard “Pictograms”, the worker, both on-or-off the job, will be able to quickly recognize potential chemical hazards. This lesson will walk users through how to identify them and their meanings.
