General information - dangerous goods
A substance or a product can be dangerous or not dangerous. A substance or a product that is not dangerous per se may become dangerous, depending on the means of transportation and if the substance or the product is transported together with other substances.
In transport situations, the concept of dangerous goods includes a variety of different substances and products that in one way or the other may imply risks for health, safety, property, or the environment when transported or used. There are substances and products that are so dangerous that they cannot be transported by air under any circumstance.
In general, a transport means varying strains on the goods because of variations in temperature and pressure but also vibrations. It means that the risk for damages increases in proportion to the risk when the goods are handled on one location. The reason transportation is allowed is because the modern industry society cannot function without the dangerous goods, and thereby cannot do without transporting it. Most types of goods are dangerous. That means that they have deleterious characteristics, depending on disadvantageous external factors. Some risks and dangers may be predicted in some types of goods, while others cannot be predicted without special knowledge of the characteristics of the goods. Some dangerous goods are forbidden for airtransport.
Dangerous goods are categorized in different classes depending on their specific characteristics, and with that, their level of dangerousness. Every class has a number of subcategories. The content of the subcategories is not exhaustive, but it covers the main part of the commercially most significant substances with dangerous characteristics.
Class 1: Explosive substances and objects
Ammunition, explosives, ignition substances and pyrotechnical products. The most common pyrotechnical products are fireworks and pyrotechnical safety equipment.

Class 5: Oxidizing substances and organic peroxides
Bleaching agents, certain hair products and acids etc.
Class 6: Toxic and infectious substances
Toxic substances such as mercurial combinations and cyanides, but also contagious substances such as bacteria, living viruses and laboratory samples.
Class 7: Radioactive material
Certain measuring instruments and certain pacemakers.
Class 8: Corrosive substances
