Characteristics of Controlled Waste

From the National Environment Protection (Movement of Controlled Wastes between States and Territories) Measure.

Dangerous Goods Class (UN Class*) UN Code Category
1 H1 Explosive
An explosive substance or waste is a solid or liquid substance or waste (or mixture of substances or waste) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
3 H3 Flammable Liquids
The word "flammable" has the same meaning as 'inflammable". Flammable liquids are liquids, or mixtures of liquids, or liquids containing solids in solution or suspension (for example paints, varnishes, lacquers etc, but not including substances or wastes otherwise classified on account of their dangerous characteristics) which give off flammable vapour at temperatures of not more than 60.5 Celsius, closed cup test, or not more than 65.6 Celsius, open-cup test.
(Since the results of open-cup tests and of closed-cup tests are not strictly comparable and even individual results by the same test are often variable, regulations varying from the above figures to make allowances for such differences would be within the spirit of the definition).
4.1 H4.1 Flammable Solids
Solids or waste solids, other than those classified as explosives, which under conditions encountered in transport are readily combustible, or may cause or contribute to fire through friction.
4.2 H4.2 Substances or wastes liable to spontaneous combustion
Substances or wastes which are liable to spontaneous heating under normal conditions encountered in transport, or to heating up in contact with air, and then being liable to catch fire.
4.3 H4.3 Substances or wastes which, in contact with water, emit flammable gases
Substances or wastes, which, by interaction with water, are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities.
5.1 H5.1 Oxidising
Substances or wastes, which, while in themselves not necessarily combustible, may, generally by yielding oxygen, cause or contribute to, the combustion of other materials.
5.2 H5.2 Organic Peroxides
Organic substances or wastes which contain the bivalent -O-O- structure are thermally unstable substances which may undergo exothermic self-accelerating decomposition.
6.1 H6.1 Poisonous (acute)
Substances or wastes liable either to cause death or serious injury or to harm human health if swallowed or inhaled or by skin contact.
6.2 H6.2 Infectious substances
Substances or wastes containing viable microorganisms or their toxins which are known or suspected to cause disease in animals or humans.
8 H8 Corrosives
Substances or wastes which, by chemical action, will cause severe damage when in contact with living tissue, or in the case of leakage, will materially damage, or even destroy, other goods or the means of transport; they may also cause other hazards.
9 H10 Liberation of toxic gases in contact with air or water
Substances or wastes which, by liberation with air or water, are liable to give off toxic gases in dangerous quantities.
9 H11 Toxic (delayed or chronic)
Substances or wastes which, if they are inhaled or ingested or if they penetrate the skin, may involve delayed or chronic effects, including carcinogenicity.
9 H12 Ecotoxic
Substances or wastes which if released present or may present immediate or delayed adverse impacts to the environment by means of bioaccumulation and/or toxic effects upon biotic systems.
9 H13 Capable of yielding another material which posses H1-H12
Capable by any means, after disposal, of yielding another materials e.g. leachate, which possesses any of the characteristics listed above.
    Other Reasons
Potential to have a significant adverse impact on ambient air quality.
Potential to have a significantly adverse impact on ambient marine, estuarine or fresh water quality.
