The Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS), 29 CFR 1910.1200(g) (as revised in 2012) aligns the HCS with the United Nations (UN) Globally Harmonized System of Classification and Labeling of Chemicals (GHS). To enhance hazard communication practices the current HCS standard provides the requirements for use of the Safety Data Sheet (SDS) in the workplace. The HCS requires new labels and pictograms on chemicals to communicate the hazards to which users may be exposed. This course provides the learner with a survey of hazardous chemical labels, pictograms and the SDS. This course is intended for any employee of any profession. What was once a standard for the worker’s right-to-know, the new HCS provides workers with the right-to-understand.
