Purpose of the Standard

The purpose of the HCS is to ensure that:

  1. the hazards of all chemicals produced or imported are classified, and
  2. information about the classified hazards is transmitted to employers and employees.

Classifying the potential hazards of chemicals, and communicating information concerning hazards and appropriate protective measures to employees, may include:

Sample GHS Compliant Label
Globally Harmonized System sample compliant chemical label
  • developing and maintaining a written hazard communication program;
  • listing hazardous chemicals present;
  • labeling containers of chemicals in the workplace;
  • labeling containers of chemicals being shipped to other workplaces;
  • preparing and distributing SDSs to employees and downstream employers;
  • developing and implementing employee training programs.
