GHS specifies elements that are required to appear on certain chemical labels. For example, depending on the toxicity of a chemical, the pictograms and hazard statements may not be necessary.


For all chemicals, regardless of toxicity or hazards, the product identifiers, precautionary statements, and suppliers information are all required.


  • Hazard Statement: A universal phrase is assigned to hazard category; the phrase will describe how it is hazardous. (e.g., “Harmful to aquatic life”, “Harmful if swallowed”)
  • Pictogram: A diamond with a red border that has a symbol inside depicting a hazard class (e.g., skin irritation/corrosion).
  • Precautionary Statement: A statement with the recommended precautionary steps to prevent the negative effects that can result from exposure to a chemical or product. It may also be for prevention, storage, disposal, and response.
  • Product identifier: A method to identify a specific chemical or mixture usually through the use of names or numbers on the safety data sheet (SDS) or hazardous product label
  • Signal Word: A word used to describe the severity associated with the hazard and alert people using the product of the potential hazard. Currently, there are two signal words:
    • o Warning: less severe hazard
    • o Danger: more severe hazard
  • Supplier Identification: The name, address, and telephone number of the supplier of the chemical, mixture, or product must be on the GHS.
