Globally Harmonized System of Classification & Labeling of Chemicals

About GHS

Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS) incorporates the United Nations’ Globally Harmonized System of Classification and Labeling of Chemicals (GHS) to improve safety and protect the health of anyone working with chemicals.

The Final Rule states that all chemical manufacturers, importers, distributors and employers must comply with all modified provisions. All distributors can no longer ship chemicals labeled under the old HCS. Employers must update alternative workplace labeling and hazard communication program and provide additional employee training for newly identified physical or health hazards.

A GHS-compliant label must contain these six elements:

• • Product name or identifier
  • Signal word
  • Hazard statements
• • Precautionary statements
  • Supplier identification
  • Pictograms

On May 20, 2024, OSHA issued a final rule that updates the HCS to align with the seventh revision of GHS and better protect workers. The updated standard requires labels on small packaging to be clearer and easier to read and allows workers and first responders to react faster in emergencies. The updates took effect on July 19, 2024.
