GHS Hazard Communication
Starting in 2013, OSHA began the phased implementation of new a Hazard Communication Standard (HCS) aligned with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Under the new rules, workers must be trained to understand and apply GHS-compliant labels and safety data sheets (SDSs), and chemical manufacturers, distributors, and importers must label have GHS-compliant labels and SDSs for their products. The new GHS HCS rules are intended to ensure that workers understand and can identify any potential hazards associated with the use of or exposure to chemical materials in the workplace. Although the general premise of the standard has not changed, the types of hazards identified and the way those hazards are communicated has. The revisions to OSHA's standard aim to ensure that true potential hazards are identified, helping to minimize workplace complacency associated with the over-warning that accompanied the previous material safety data sheet (MSDS).
