  3. Definition of a Class 5.1 • A class 5.1 product is defined as • Class 5.1 dangerous goods are those substances which, although not necessarily combustible themselves, may readily liberate oxygen, or be the cause of oxidation of other materials. As a result, they may start or contribute to the start of a fire and increase the violence of a fire. • (Note 1) • Note (1) NT Worksafe Bulletin – Storage of minor quantities of class 5.1 oxidising agents

  4. Properties of Class 5.1 • Oxidising agents may also react violently or even explosively with other substances, a well known example of this being calcium hypochlorite and brake fluid. Oxidising agents must be kept away from all flammable and combustible materials, and most other dangerous goods. Since oxidising agents supply oxygen to a fire, it is not usually possible to fight fires involving Class 5.1 substances by depriving the fire of air eg, the use of fire blankets, carbon dioxide and Halon fire extinguishers. Another hazard posed by oxidising agents is their ability to cause corrosion of many materials, and stores for Class 5.1 dangerous goods should be designed with this in mind. • Many oxidising agents are also hazardous to people through inhalation of dusts and vapours, skin and eye contact and ingestion. • (Note 1) • Note (1) NT Worksafe Bulletin - Storage of minor quantities of class 5.1 oxidising agents

  5. Class 5.1 Label for Oxidising Agents Note 1 * Hazard description on No. 5.1 label (Division 5.1) may alternatively read “OXIDISING AGENT” Note(1) Source the Australian Dangerous Goods Code 7th Edition page 426

  6. Classification of Class 5.1 Products • Oxidising Solids • A solid substance is classified in Division 5.1 if the 4:1 or 1:1 sample-to-cellulose ratio (by mass) tested, exhibits a mean burning time equal to or less than the mean burning time of a 3:7 mixture (by mass) of potassium bromate and cellulose. • Oxidising Liquids • A liquid substance is classified in Division 5.1 if the 1:1 mixture, by mass, of substance and cellulose tested, exhibits a mean pressure rise time less than or equal to the mean pressure rise time of a 1:1 mixture, by mass, of 65% aqueous nitric acid and cellulose. • (Note 1) • Note (1) Source the Australian Dangerous Goods Code 7th Edition page 76 & 77

  7. Storage • STACKS • Where packages of oxidizing agents are kept in stacks (i.e. pallet racking is not used), the maximum capacities of such stacks shall be as set out in Table 4.1. Where pallet racking is not used— • (a) stacks of packages shall be limited to 3 m in height; and • (b) a free air space of not less than 1.2 m shall be maintained between stacks of oxidizing agents and the outer walls of the building. • The requirements of Items (a) and (b) do not apply where pallet racking is used. • NOTE: Where containers are to be stacked, the relevant MSDS or the supplier of the oxidizing agent should be consulted for further advice on maximum stacking heights. Stacks shall be separated from each other by at least 3 m or by concrete walls of not less than 100 mm thickness.
