The Dangerous Goods class is a number assigned to a group of dangerous goods which exhibit a single or most significant risk by certain criteria. Dangerous goods have immediate effects and are explosive, flammable, corrosive, chemically reactive, highly combustible, acutely toxic, radio active or infectious. (Some hazardous substances are also classified as dangerous goods.)
Indicating the hazard and the predominant risk, the class assists to determine the response required in the event of an emergency. It also provides a basis for packaging, labelling, storing and moving goods. The dangerous goods class is allocated to a substance under the Australian Code for the Transport of Dangerous Goods by Road and Rail (ADG Code).
Where the substance has hazards in more than one class. ADG Code, paragraph 2.4.5 (or this Guide page 371) determines precedence (and Sub-Risk). The other class(es) are the Sub-Risk(s) of the substance.
Classes 1, 5.2, 6.2 and 7 always take precedence over the other hazards (and hence not included in the table).
For multiple risks or where there are Sub-Risks, the lowest value (most severe) packaging group applies to the goods.

Explosive substances decompose when triggered by sparks or friction, causing a chain reaction. Although such a decomposition is often attended by fire, the reaction does not need an external source of oxygen. A flammable vapour/air mixture is not an explosive.
See Flammability Limits
The intensity, frequency and duration of any contact with an agent that is present in the environment.
Exposure standards detail levels of airborne concentrations of substances which, according to current knowledge, does not impair the health, or cause discomfort to the workers. Exposure standards are generally expressed as a time-weighted average (TWA) concentration of a substance over an eight-hour working shift, and applied to an eight-hour day, for a five-day working week over an entire working lifetime. TWA permit excursions above the limit provided that they are compensated by equivalent excursions below the limit during the workday.
Worksafe has produced the publication, Exposure Standards for Atmospheric Contaminants in the Occupational Environment. Where no exposure standards have been allocated, acceptable overseas exposure standards may be used with the source clearly identified. It should be clearly recorded if no exposure standard has (yet) been allocated for the substance (and it should be understood that this does not mean that the product has a low hazard).

The concentration range of a flammable vapour in air at which a flame can be propagated or an explosion will occur, with an ignition source. There is always an upper (too rich) and a lower limit (too lean) that should be included. The wider the flammability limits, the more violent is the explosion of a cloud of vapour reaches a source of ignition. The terms flammability limits and explosive limits mean the same.
The flashpoint is the lowest temperature at atmospheric pressure (101.3 kPa) at which a liquid gives off so much combustible vapour at the liquid surface that this vapour, when mixed intimately with air, can be ignited by a flame or spark.
A specific definition for the purposes of classifying substances is provided in AS 2106. The flashpoint is determined by the closed cup (c.c.). The lower the flashpoint, the higher the risk of ignition and fire.
The majority of flammable gases have flash points far below 0EC and the indication 'flammable gas' is used instead.

Are liquids which can dissolve substances. Organic solvents are also used in paints and adhesives and include;
aromatic solvents eg. xylene and toluene;
aliphatic hydrocarbons eg. kerosene and n-heptane;
alcohols eg. ethanol and isopropanol;
glycols eg. ethylene glycol;
esters eg. iso-propyl acetate;
chlorohydrocarbons eg. methylene chloride;
ethers eg. diethylene glycol;
ketones and aldehydes eg. acetone and MEK.
The amount of a substance which may be dissolved in water. Solubility in water should be expressed in grams/litre (g/l), or parts per million (ppm) parts of water may also be used. The temperature, in EC, at which the solubility was measured should be stated if known.
Indicates whether the substance floats on water or sinks. For gases condensed to the liquid phase, the density of the liquid phase is given. As a ratio, the specific gravity of the product (also, and more properly, known as the relative density), is its mass compared to the mass of an equal volume of water. The Specific Gravity of water is therefore by definition equal to one.
See bunding
Solids or liquids which spontaneously heat and ignite in contact with air. (eg. white phosphorus.)
The Standard for the Uniform Scheduling of Drugs and Poisons (SUSDP) as produced by the National Health and Medical Research Council (NHMRC) is the basis for State and Territory Poisons Act legislation (which may differ between regions in detail). The legislation applies restrictions at the point of sale.
There are nine Poisons Schedules listing substances or types of substances which require certain labelling and description, packaging (inner and outer), controls on advertising and supply, storage, and for some, the permitted level of impurities.
See Bulk Store
A person other than the an employee who is engaged by a prime contractor to transport the goods.
A substance sublimes if on heating it passes directly from the solid to the vapour phase, without melting or passing through the liquid phase. This should be mentioned under boiling point.
A risk, indicated by reference to a Dangerous Goods class, in addition, by the rules of precedence, (refer section 2 of ADG Code) to the principal class to which the product is assigned.
See Subsidiary Risk.
Term used to describe Chemicals, materials, goods, products, formulations and preparations, ie. whether or not pure or single substances. A term used for any natural or artificial substance whether as a solid, liquid, gas or vapour form, but excluding articles.
Packages as approved by the Competent Authorities as superior packages.
Means importers, manufacturers, wholesalers and distributors of workplace substances.
The National Standard for Plant defines supplier as including a person who supplies a plant for use in a workplace by way of sale, lease, exchange or hire, whether as a principal or agent for another.
An abbreviation, refer Standard for the Uniform Scheduling of Drugs and Poisons.
The combined toxic effect is greater than the sum of each agent alone (ie. 1+2=5). An example is carbon tetrachloride and ethanol.
A tank is a receptacle with a capacity of liquids of more than 250 litres and of gases with more than 500 litres (ie. a tank is not a packaging).
See teratogenic.
Able to produce abnormalities in a developing foetus, that is, causing birth defects. The EEC now refers to toxic to reproduction.
Threshold limit value. In three categories, these values are an exposure standard determined by the American Conference of Governmental Industrial Hygienists (ACGIH). It is the airborne concentration of substances at which persons may be exposed in the course of their daily work, on an indefinite basis without adverse effect. (Refer Appendix 5)
Not used in the National Commission publications, it approximates the Exposure Standard TWA basis for most substances.
See Threshold Limit Value
The ability of a substance to cause damage to cells or tissue whether or not at the point of contact. Refer also Appendix 2 for definition when used to describe a substance in terms of its health effects.
Refers to the potential ability of a substance to cause deleterious (toxic) effects.
Low; causes readily reversible changes which disappear after exposure stops. Causes some discomfort.
Moderate; may cause reversible or irreversible changes to exposed tissue but not permanent injury. Causes considerable discomfort.
High; capable of causing death or permanent injury in normal use.
The study or relating to toxic effects
A registered product name used by the manufacturer or supplier. The name need not relate to the chemical name of the product or its ingredients.
Transport containers includes freight containers, portable tanks, tank containers, demountable tanks and Intermediate Bulk Containers used in connection with the transport of dangerous goods.
An expression to indicate the extent to which a container is filled. Often expressed as a percentage of free space of the capacity of the container.
A device for transporting as a unit consisting of a number of packages which are those which are;
< stacked and secured (by strapping, wrapping etc.) to a load board such as a pallet;
< placed in a protective outer receptacle such as a pallet box;
< permanently secured in a sling.
Excludes single large receptacles such as a portable tank and freight containers etc.
Also less commonly known as the Substance Identification Number (SI) and UN Transport Number, it is a system of four digit numbers, assigned to a substance, or a group of chemicals with similar hazardous properties (eg. cresols).
Based on a common characteristic, the UN number provides a very useful and important link (via sub-section 9 of the ADG Code) to the Hazchem Code, Emergency Procedure Guides (to provide emergency information), dangerous goods class (to assist for safe handling and storage), the packaging group (to indicate the degree of hazard) and the method for safe packaging.
Where the substance is not listed (ie. under its Correct Shipping Name in sub-section 9.4 of the ADG Code), the UN number may be deduced (ADG Code sections 2.6.1 and 2.6.2 by matching the class, sub-risk and packaging group of the substance with the listed substances of sub-section 9.4, each of which have corresponding UN numbers. ADG Code sub-section 2.4 should be used to determine the class, sub-risk and packaging group.
A substance which can undergo changes by way of decomposition, condensation, self-reaction or polymerisation.
Use is defined to mean for the National Model Regulation as the production, handling, storage, transport or disposal of substances in the workplace. Excludes transport where carried in compliance with the ADG Code or where held in transit for longer than two working days. Use also excludes the transport of substances carried in compliance with the International Maritime Dangerous Goods Code, the Technical Instructions for the safe Transport of Dangerous Goods by Air or relevant Commonwealth, State or Territory legislation.
Use is also defined in the National Standard for Plant as to work from, operate, maintain, inspect and clean.
The gas of a substance which is normally a solid or a liquid, and is also formed above a liquid or solid by evaporation.
The mass (density) of vapour compared to an equal mass (density) of air. With air assumed to be 1.0, vapours with a density greater than 1.0 will sink (staying close to floor.
The pressure over a liquid created by its vapour. The higher the vapour pressure, the more volatile the substance.
The mobility (thickness) of a liquid. Usually provided in technical measurements but for the MSDS may be described in common descriptive terms such as 'like water', `oil', `syrup', `paste' etc.
Readily able to pass into the vapour state.
A term which can mean practical or reasonably practical.
Any place, including aircraft, ship or vehicle, where a person works, likely to work, or goes while at work.
Worksafe Australia, (the National Occupational Health and Safety Commission), under Commonwealth law is a tripartite body only authorised to disseminate information for use at workplace level. That information may be adopted or formally referenced by State Government legislation.
