Dangerous Goods Labels

Dangerous goods are substances or articles with hazardous properties which may, if handled incorrectly, explode, asphyxiate (choke), burn, make explosive mixtures, poison, eat skin or metal, pollute the environment or become unstable if mixed with other products.

For ease of identification of dangerous goods, the international community has created a classification system. All dangerous goods are included in one of nine primary classes. In some cases it has also been necessary to sub-divide some of the classes into divisions in order to adequately provide articulations for the dangers of the individual goods.

The 9 Classes of Dangerous Goods

The transportation of dangerous goods is controlled and governed by a variety of different regulatory regimes, operating at both the national and international levels. Prominent regulatory frameworks for the transportation of dangerous goods include the United Nations Recommendations on the Transport of Dangerous Goods, ICAO’s Technical Instructions, IATA’s Dangerous Goods Regulations and the IMO’s International Maritime Dangerous Goods Code. Collectively, these regulatory regimes mandate the means by which dangerous goods are to be handled, packaged, labelled and transported.

Regulatory frameworks incorporate comprehensive classification systems of hazards to provide a taxonomy of dangerous goods. Classification of dangerous goods is broken down into nine classes according to the type of danger materials or items present ie; Explosives, Gases, Flammable Liquids, Flammable Solids, Oxidizing Substances, Toxic & Infectious Substances, Radioactive Material, Corrosives and Miscellaneous Dangerous Goods.

Class 1 - Explosive Class 1.4 - Explosive

Class 1 - Explosives
Explosives are materials or items which have the ability to rapidly conflagrate or detonate as a consequence of chemical reaction. Explosives are capable by chemical reaction of producing gases at temperatures, pressures and speeds as to cause catastrophic damage through force and/or of producing otherwise hazardous amounts of heat, light, sound, gas or smoke.

  • 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
  • Division 1.4: Substances and articles which present no significant hazard; only a small hazard in the event of ignition or initiation during transport with any effects largely confined to the package
  • Division 1.5: Very insensitive substances which have a mass explosion hazard
  • Division 1.6: Extremely insensitive articles which do not have a mass explosion hazard

Commonly Transported Explosives
Ammunition & Cartridges, Fireworks & Pyrotechnics, Flares, Blasting caps & detonators, Fuse, Primers, Explosive charges (blasting, demolition etc), Detonating Cord, Air Bag Inflators, Igniters, Rockets, TNT & compositions, RDX & compositions, PETN & compositions.

Class 2.1 - Flammable Gas Class 2.2 - Non-flammable-Non-Toxic-Gas Class 2.3 - Toxic Gas

Class 2 - Gasses
Gases are defined by dangerous goods regulations as substances which have a vapour pressure of 300 kPa or greater at 50°c or which are completely gaseous at 20°c at standard atmospheric pressure, and items containing these substances. The class encompasses compressed gases, liquefied gases, dissolved gases, refrigerated liquefied gases, mixtures of one or more gases with one or more vapours of substances of other classes, articles charged with a gas and aerosols.

Gases are capable of posing serious hazards due to their flammability, potential as asphyxiants, ability to oxidize and/or their toxicity or corrosives to humans.

  • Division 2.1: Flammable gases
  • Division 2.2: Non-flammable, non-toxic gases
  • Division 2.3: Toxic gases

Commonly Transported Gases
Aerosols, Compressed Air, Hydrocarbon Gas-Powered Devices, Fire Extinguishers, Gas Cartridges, Fertilizer Ammoniating Solution, Insecticide Gases, Refrigerant Gases, Lighters, Acetylene & Oxyacetylene, Carbon dioxide, Helium & Helium Compounds, Hydrogen & Hydrogen Compounds, Oxygen & Oxygen Compounds, Nitrogen & Nitrogen Compounds, Natural Gas, Oil Gas, Petroleum gases, Butane, Propane, Ethane, Methane, Dim ethyl Ether, Propane & Propylene and Ethylene.

Class 3 - Flammable Liquid

Class 3 - Flammable Liquids
Flammable liquids are defined by dangerous goods regulations as liquids, mixtures of liquids or liquids containing solids in solution or suspension which give off a flammable vapour (have a flash point) at temperatures of not more than 60-65°C, liquids offered for transport at temperatures at or above their flash point or substances transported at elevated temperatures in a liquid state and which give off a flammable vapour at a temperature at or below the maximum transport temperature.

Flammable liquids are capable of posing serious hazards due to their volatility, combustibility and potential in causing or propagating severe conflagrations.

Commonly Transported Flammable Liquids
Acetone & acetone oils, Adhesives, Paints & lacquers & varnishes, Alcohols, Perfumery products, Gasoline & Petrol, Diesel fuel, Aviation fuel, Liquid bio-fuels, Coal tar & coal tar distillates, Petroleum crude oil, Petroleum distillates, Gas oil, Shale oil, Heating oil, Kerosene, Resins, Tars, Turpentine, Carbamate insecticides, Organochlorine pesticides, Organophosphorus pesticides, Copper based pesticides, Esters, Ethers, Ethanol, Benzene, Butanols, Dichloropropenes, Diethyl ether, Isobutanols, Isopropyls, Methanol, Octanes.

Class 4.1 - Flammable Solid Class 4.2 - Spontaneously Combustible Class 4.3 - Dangerous When Wet

Class 4 - Flammable Solids
Flammable solids are materials 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 or solid desensitized explosives. Also included are substances which are liable to spontaneous heating under normal transport conditions, or to heating up in contact with air, and are consequently liable to catch fire and substances which emit flammable gases or become spontaneously flammable when in contact with water.

Flammable solids are capable of posing serious hazards due to their volatility, combustibility and potential in causing or propagating severe conflagrations.

Division 4.1: Flammable solids

Division 4.2: Substances liable to spontaneous combustion

Class 5.1 - Oxidizing Agent Class 5.2 - Organic Peroxide

Class 5 - Oxidizing Substances
Oxidizers are defined by dangerous goods regulations as substances which may cause or contribute to combustion, generally by yielding oxygen as a result of a redox chemical reaction. Organic peroxides are substances which may be considered derivatives of hydrogen peroxide where one or both hydrogen atoms of the chemical structure have been replaced by organic radicals.

Oxidizers, although not necessarily combustible in themselves, can yield oxygen and in so doing cause or contribute to the combustion of other materials. Organic peroxides are thermally unstable and may exude heat whilst undergoing exothermic autocatalytic decomposition. Additionally, organic peroxides may be liable to explosive decomposition, burn rapidly, be sensitive to impact or friction, react dangerously with other substances or cause damage to eyes.

Class 6.1 - Toxic Class 6.2 - Infectious Substances

Class 6 - Toxic Substances
Toxic substances are those which are liable either to cause death or serious injury or to harm human health if swallowed, inhaled or by skin contact. Infectious substances are those which are known or can be reasonably expected to contain pathogens. Dangerous goods regulations define pathogens as microorganisms, such as bacteria, viruses, rickettsiae, parasites and fungi, or other agents which can cause disease in humans or animals.

Toxic and infectious substances can pose significant risks to human and animal health upon contact.

Class 7 - Radioactive

Class 7 - Radioactive Materials

Dangerous goods regulations define radioactive material as any material containing radionuclides where both the activity concentration and the total activity exceeds certain pre-defined values. A radionuclide is an atom with an unstable nucleus and which consequently is subject to radioactive decay.

Whilst undergoing radioactive decay radionuclides emit ionizing radiation, which presents potentially severe risks to human health.

Environment Hazard

Environment Hazard
Some chemicals pose a danger to aquatic life. The International Maritime Dangerous Goods code part states that all marine pollutants must be labelled for transport by sea, with the exception of packages containing less than or equal to 5L or 5kg. This is a sub-risk label only and is used with the other primary classes of labels.

Elevated Temperature

Elevated Temperature
Transport units and placard units containing a substance that is transported or offered for transport in a liquid state at a temperature equal to or exceeding 100°C, or in a solid state at a temperature equal to or exceeding 240°C. Used in conjunction with Dangerous Goods Class Labels for substances requiring storage or transport at elevated temperatures.

Limited Quantity (AIR)

Limited Quantity (AIR)
Limited Quantity labels are used for the transport of dangerous goods packaged in limited quantities. Labels with the ‘Y’ are used for transportation by AIR.

Limited Quantity (ROAD, RAIL & SEA)

Limited Quantity (ROAD,RAIL & SEA)
Limited Quantity labels are used for the transport of dangerous goods packaged in limited quantities. Labels WITHOUT the ‘Y’ are used for transportation by road, rail and sea.

The Australian Code for the Transport of Dangerous Goods by Road and Rail (ADG Code) offers reduced regulatory requirements for transporting dangerous goods in limited quantity packaging. Which are relatively small packages containing selected low hazard dangerous goods. Even for dangerous goods transported in limited quantities, there are some packaging and labelling requirements you need to follow:

  • Goods must be carried in small containers (e.g., bottles), which are then packed in boxes or on shrink-wrapped trays
  • Packages must pass certain performance tests requirements
  • The maximum gross weight is 30kg for boxes or 20kg for shrink wrapped trays
  • Outer packages must bear limited quantities mark and hazard symbols
  • Dangerous goods transported in limited quantities must be communicated in a shipping document

Limited quantity placards applied to cargo transport units are required to be a minimum of 250mm x 250mm in size.

The limited quantity mark applied to packages is required to be a minimum of 100mm x 100mm. If the size of the package requires, the dimensions may be reduced to not less than 50 mm x 50 mm.
