Globally Harmonized System (GHS)
The GHS includes criteria for the classification of health, physical and environmental
hazards, as well as specifying what information should be included on labels of hazardous
chemicals as well as safety data sheets. GHS classifications are ranked in categories
1-4 with 1 being the most hazardous and 4 being the least hazardous. More details
about the classification are provided via H-codes and can be found in the SDS section of the CHP. For more information that is beyond the scope of this section: https://www.osha.gov/hazcom/global
