OSHA's Hazard Communication Standard (HCS) is part of the Code of Federal Regulations (CFR) used to convey occupational safety and health risks associated with chemicals and toxic substance hazards in the workplace, during manufacturing or transportation, as well as during releases or exposures. The HCS requires labels and pictograms be placed on chemicals and other substances to communicate the hazards to which users may be exposed. The goal of this course is to provide all staff with a review of hazardous chemical labels, pictograms, and Safety Data Sheets (SDSs). Unless otherwise stated, the information in this course was sourced from the Hazard Communication Standard (29 C.F.R. §1910.1200, 2017).
