OSHA Issues Final Rule on HazCom Standard to Align with Revised GHS In July, OSHA’s final rule on the Hazard Communication Standard for classifying and labeling chemicals went into effect, and will be phased in over a four year period. Changes were made to the standard so that it will align with the 7th revision of the UN’s Globally Harmonized System (GHS), and will impact chemical manufacturers, importers, distributors and employers utilizing hazardous chemicals. The updated standard includes changes to definitions that will impact labeling, handling and classification of hazardous chemicals. Here are some high points: • Additions the definition of Bulk shipment, Combustible dust, Gas, Immediate outer package, Liquid, Physician or other licensed health-care professional (PLHCP), Released for shipment, and Solids. • Clarifications to the definition of Exposure or Exposed, Pyrophoric gas • An addition to Section (f)(5) Transportation clarifying labeling for bulk shipments and pictograms to align with Department of Transportation (DOT) requirements. This solves the issue of having to use both HCS and DOT pictograms for the same hazard. • Smaller containers may utilize special labelling. Capacities under 100 ml will have minimum labeling requirements of a product identifier, applicable pictograms, signal word, manufacturer’s name and phone numb
