Hazard Statements

J&K Scientific uses GHS (Globally Harmonized System of Classification and Labeling of Chemicals) hazard statements. Hazard statements are assigned a unique alphanumeric code which consists of one letter and three numbers as follows:

  • The letter "H" (for "hazard statement")
  • A number designating the type of hazard as follows:
    "2" for physical hazards
    "3" for health hazards
    "4" for environmental hazards
  • Two numbers corresponding to the sequential numbering of hazards arising from the intrinsic properties of the substance or mixture, such as explosive properties (codes from 200 to 210), flammability (codes from 220 to 230), etc.
