CLASS 5 – DIVISION 5.1 - OXIDISING SUBSTANCES

Oxidising substances pose a hazard because of their ability to chemically oxidise matter, including living tissue. Strong oxidisers can greatly enhance the flammability of other material. Although these substances are not necessarily combustible in themselves, they may readily yield oxygen and in so doing cause or contribute to the combustion of other materials.

 

Division 5.1 substances can be in UN Packing Groups I, II, or III.

Note: Ammonium Nitrate and mixtures or emulsions containing more than 45% ammonium nitrate are prescribed as a Security Sensitive Dangerous Substances (SSDS) due to being an explosive precursor and are classified as Class 5.1 dangerous goods. Ammonium nitrate substances are Division 1.5 and Ammonium nitrate fertilizers are Class 9 substances. Transportation of Class 5.1 Security Sensitive Ammonium Nitrate (SSAN) falls under Australian Explosives legislation and requires additional licensing to handle, transport and store. Ammonium nitrate solutions (fully dissolved in water) and ammonium nitrate products that are Class 1 explosives are not SSDS.

PACKING GROUPS

  • Packing Group I, for any material which, in either concentration tested, exhibits a mean burning time less than the mean burning time of a 3:2 potassium bromate/cellulose mixture.

  • Packing Group II, for any material which, in either concentration tested, exhibits a mean burning time less than or equal to the mean burning time of a 2:3 potassium bromate/cellulose mixture and the criteria for Packing Group I are not met.

  • Packing Group III for any material which, in either concentration tested, exhibits a mean burning time less than or equal to the mean burning time of a 3:7 potassium bromate/cellulose mixture and the criteria for Packing Group I and II are not met.
