GHS03 have you seen the “O” in Oxidizer’s


The dangerous materials definition of an oxidizing agent is a substance that can cause or contribute to the combustion of other material.

  • Oxidizing gases, category 1
  • Oxidizing liquids, categories 1, 2, 3
  • Oxidizing solids, categories 1, 2, 3


The GHS pictogram for an OXIDIZER HAZARD, has an “O” in the middle of the pictogram that represents “OXYGEN” being supplied to feed the fire by the oxidizing agent.

The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an internationally agreed-upon standard managed by the United Nations that was set up to replace the assortment of hazardous material classification and labelling schemes previously used around the world. “GLOBAL HARMONIZED SAFETY SYSTEM for CLASSIFIED CHEMICAL LABELLING” – Core elements of the GHS include standardized hazard testing criteria, universal warning pictograms, and harmonized safety data sheets which provide users of dangerous goods with a host of information. The system acts as a complement to the UN Numbered system of regulated hazardous material transport. Implementation is managed through the UN Secretariat.
