How many dangerous goods classes are there




















The subsidiary class is the other class that further identifies the hazards of the dangerous goods. More than one subsidiary class is possible. For most of dangerous goods, the primary class and subsidary class can be found in Dangerous Goods List.

For goods having multiple risks which are not specifically mentioned by name in Dangerous Goods List, you have to follow the following hazard precedence rules to determine their primary hazard class and subsidiary class.

If above two rules do not apply, please refer to the following hazard precedence table to choose primary hazard. Some of these classes are subdivided into divisions:. Class 4: Flammable solids; substances liable to spontaneous combustion; substances which, on contact with water, emit flammable gases.

Some dangerous goods fall into one of 3 packing groups depending on the degree of danger they present to people and equipment:. The Australian Dangerous Goods Code provides more information about the classifications and divisions of dangerous goods, and if they are assigned to a packing group. Each dangerous goods class is represented by a placard - a distinctive and specific class label in the shape of a diamond.

For example:. The UN number can be found on the label, transport document or safety data sheet. Chemical oxygen generators, Ammonium nitrate fertilizers, Chlorates, Nitrates, Nitrites, Perchlorates, Permanganates, Persulphates, Aluminium nitrate, Ammonium dichromate, Ammonium nitrate, Ammonium persulphate, Calcium hypochlorite, Calcium nitrate, Calcium peroxide, Hydrogen peroxide, Magnesium peroxide, Lead nitrate, Lithium hypochlorite, Potassium chlorate, Potassium nitrate, Potassium chlorate, Potassium perchlorate, Potassium permanganate, Sodium nitrate, Sodium persulphate.

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. Division 6. 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.

DGI have the ability to service all customer requests pertaining to the logistics of radioactive material; packing, packaging, compliance, freight forwarding and training. Whilst undergoing radioactive decay radionuclides emit ionizing radiation, which presents potentially severe risks to human health. Commonly Transported Radioactive Material. Corrosives are substances which by chemical action degrade or disintegrate other materials upon contact. DGI have the ability to service all customer requests pertaining to the logistics of corrosives; packing, packaging, compliance, freight forwarding and training.

Corrosives cause severe damage when in contact with living tissue or, in the case of leakage, damage or destroy surrounding materials. Miscellaneous dangerous goods are substances and articles which during transport present a danger or hazard not covered by other classes. This class encompasses, but is not limited to, environmentally hazardous substances, substances that are transported at elevated temperatures, miscellaneous articles and substances, genetically modified organisms and micro-organisms and depending on the method of transport magnetized materials and aviation regulated substances.

DGI have the ability to service all customer requests pertaining to the logistics of miscellaneous dangerous goods; packing, packaging, compliance, freight forwarding and training.

No matter how cargo is being transported, it must comply with The United Nations UN nine hazard classes for dangerous goods. Class 1 items are not usually shipped by air and are divided into six subdivisions.

They cover substances that have an explosion hazard, explosions that may project fragments and firebrands, and fire hazards. This class is divided into three subdivisions that include flammable gases, toxic gases and gases that are neither flammable or toxic such as helium and oxygen.

Class 3 comprises liquids or mixtures of liquids that will give off flammable vapours at specific temperatures and have a flash point of not more than Flammable solids are divided into three subdivisions that include highly flammable solids, solids that are likely to spontaneously and substances that, if they come into contact with water, emit flammable gases.
