Chemical labels also need clear written information so that anyone handling the substance knows exactly what the risks are and how to deal with them safely. Under standards like OSHA’s Hazard Communication Standard and GHS/WHMIS, a compliant chemical label must include, in addition to the product identifier, signal word, and pictogram(s):

  1. Hazard statement(s)
    • Standardized phrases that describe the nature of the hazard and, where appropriate, the degree of hazard.
    • Example: “Causes serious eye damage” or “Highly flammable liquid and vapour.”
    • These statements are tied directly to the hazard classification of the chemical.
  2. Precautionary statement(s)
    • Instructions on how to prevent or minimize harmful effects, how to respond in an emergency, how to store the substance, and how to dispose of it.
    • Examples:
      • Prevention: “Keep away from heat/sparks/open flames.”
      • Response: “IF ON SKIN: Wash with plenty of water.”
      • Storage: “Store locked up.”
      • Disposal: “Dispose of contents/container in accordance with local regulations.”
  3. Supplier identification (responsible party details)
    • Name, address, and telephone number of the manufacturer, importer, or other responsible party.
    • This allows users and emergency responders to contact someone for more detailed information if needed.

These items (product identifier, pictogram(s), signal word, hazard statements, precautionary statements, and supplier identification) make up the core set of required label elements under GHS-aligned regulations such as OSHA HazCom and WHMIS.
