The GHS 7 is an international hazard classification system for chemicals created by the United Nations. The hazards are communicated on labels and safety data sheets including the safe way to store, use and dispose of chemicals.

Adopting the new classification system means:

  • the existing HSNO hazard classification system will no longer be used
  • the introduction of the Hazard Classification Notice 2020 incorporating the new GHS 7 classifications. A framework is established to classify substances that are hazardous to the terrestrial environment
