HAZARD PICTOGRAMS

GHS pictogram codes and descriptons

The Globally Harmonized System of Classification and Labeling of Chemicals or GHS includes the following hazard pictograms which are for workplace hazard warnings including the labeling of containers and for the transport of dangerous goods.

TRANSPORTATION PICTOGRAMS

GHS Image/Pictogram Hazard Class & Hazard Category
ExplosivesExplosives
  • Division 1.1: Substances and articles which have a mass explosion hazard
  • Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard
  • Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard
Flammable GasesFlammable Gases
  • Gases which at 20 °C and a standard pressure of 101.3 kPa:
  • -are ignitable when in a mixture of 13 per cent or less by volume with air; or
  • -have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit.
Non-flammable non-toxic gasesNon-flammable Non-toxic Gases
  • Gases which:
  • are asphyxiant - gases which dilute or replace the oxygen normally in the atmosphere; or
  • are oxidizing - gases which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does; or
  • do not come under the other divisions
Toxic gasesToxic Gases
  • Gases which:
  • are known to be so toxic or corrosive to humans as to pose a hazard to health; or
  • are presumed to be toxic or corrosive to humans because they have an LC50 value equal to or less than 5000 ml/m3 (ppm).
Flammable LiquidsFlammable Liquids
  • Liquids which have a flash point of less than 60 °C and which are capable of sustaining combustion
Flammable SolidsFlammable Solids self-reactive substances and solid desensitized explosives
  • Solids which, under conditions encountered in transport, are readily combustible or may cause or contribute to fire through friction; self-reactive substances which are liable to undergo a strongly exothermic reaction; solid desensitized explosives which may explode if not diluted sufficiently
Substances liable to spontaneous combustionSubstances Liable to Spontaneous Combustion
  • Substances which are liable to spontaneous heating under normal conditions encountered in transport, or to heating up in contact with air, and being then liable to catch fire
Substances which in contact with water emit flammable gasesSubstances which in contact with water emit flammable gases
  • Substances which, by interaction with water, are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities
Oxidizing SubstancesOxidizing Substances
  • Substances which, while in themselves not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material
Organic PeroxidesOrganic Peroxides
  • Organic substances which contain the bivalent -O-O- structure and may be considered derivatives of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic radicals
Corrosive SubstancesCorrosive Substances
  • Substances which:
  • exhibit a corrosion rate of more than 6.25 mm per year on either steel or aluminium surfaces at 55 °C
