Dangerous goods are classified into one of nine hazard classes as the United Nations (UN - United Nations). Nine classes of danger.
These classes are listed below with some typical examples and example marking:
CLASS 1 - explosive materials whose properties can explode, cause fire with explosive effect, as well as devices containing explosive substances and explosive intended for pyrotechnic effect .
1.1 - Explosives and pyrotechnic substances and products with a mass explosion hazard when the explosion instantly covers the entire load;
1.2 - Explosives and pyrotechnic substances and articles not exploding mass;
1.3 - Explosives and pyrotechnic substances and articles which have a fire hazard with a small explosive effect or without it;
1.4 - Explosives and pyrotechnic substances and articles which present a slight risk during transport only in the event of ignition or initiation, not giving the destruction of devices and packages;
1.5 - Explosives with a mass explosion hazard which are so insensitive that Transport initiation or transition from burning to detonation is unlikely
1.6 - products containing extremely insensitive detonating substances shatter mass and low probability of accidental initiation.
CLASS 2 - Gases compressed, liquefied, cooled and dissolved under pressure, meet at least one of the following conditions :
- absolute vapor pressure at 50 oC is equal to or greater than 3 kgf / cm kPa);
- critical temperature is below 50 oC
The physical condition gases are divided into:
- compressed, critical temperature below -10 oC;
- liquefied, the critical temperature is equal to or higher than -10 oC and below 70 oC;
- liquefied, the critical temperature is at or above 70 °C;
- dissolved under pressure;
- liquefied hypothermia;
- aerosols and compressed gases, are subject to special regulations.
2.1 - flammable gases;
2.2 - flammable, poisonous gas;
2.3 - flammable gases;
2.4 - flammable toxic gases;
2.5 - chemically unstable;
2.6 - chemically unstable toxic.
CLASS 3 - flammable liquids, mixtures of liquids or liquids containing solids in solution or suspension, which emit flammable vapors having Flash Point 61 oC and below.
3.1 - flammable liquid with a low flash point and a liquid with a flash point in closed crucible below minus 18 oC or with a flash in conjunction with other hazardous properties, except flammable;
3.2 - flammable liquid with a flash point average - liquid with a closed cup flash point of - 18 to + 23 oC;
3.3 - highly flammable liquid with a high flash point - a liquid with a flash point from 23 to 61 oC inclusive closed cup.
CLASS 4 - flammable substances and materials (other than those classed as explosives), which during transportation can easily catch fire from external ignition sources due to friction , absorption of moisture, spontaneous chemical reactions, as well as heating.
4.1 - flammable solids which are easily ignited by brief exposure to external sources of ignition (spark, flame or friction) and actively burn;
4.2 - pyrophoric substances, which under normal conditions of transport can spontaneously heat and ignite;
4.3 - substances that emit flammable gases in contact with water.
CLASS 5 - Oxidizing substances and organic peroxides, which can lay down to release oxygen to support
combustion, and may, in appropriate circumstances,
or mixed with other substances, to cause ignition and explosion.
5.1 - oxidizing agents, which by themselves are not combustible, but contribute to the combustibility of other substances and release oxygen during combustion, thereby increasing the intensity of the fire;
5.2 - Organic peroxides, which in most cases are combustible, may act as oxidizing agents and react dangerously with other substances. Many of them are easily ignited and sensitive to shock and friction.
CLASS 6 - Toxic and infectious substances which can cause death, poisoning or illness if swallowed or in contact
with skin and mucous membranes.
6.1 - poisonous (toxic) substances that can be toxic if inhaled (vapor, dust), ingestion or skin contact;
6.2 - substances and materials containing pathogens affecting humans and animals.
CLASS 7 - radioactive material with a specific activity of more than 70 kBq / kg (2 nCi / g).
CLASS 8 - corrosive substances that cause damage to the skin, mucous membranes of the eyes and respiratory
tract, metal corrosion and damage
to vehicles, buildings or goods and may cause fire in contact with organic materials or certain chemicals .
8.1 - acid;
8.2 - alkali;
8.3 - various corrosive substances.
CLASS 9 - substances with relatively low risks in the transportation referred to any of the previous classes,
but require the application to them
of certain rules for the transport and storage .
9. 1 - solid and liquid combustible substances and materials, whose properties do not belong to the 3rd and 4th CLASS, but under certain conditions, can be dangerous in a fire on (flammable liquid with a flash point of +61 oC to +100 oC in a closed container, fiber and other similar materials);
9.2 - substances that become corrosive and corrosive under certain conditions.
To dangerous goods that require special care during transport, the substances and materials with physic-chemical properties of a high degree of risk in accordance with GOST 19433-88, hereinafter referred to as "particularly dangerous goods":

Types of packaging
Each hazard class has its own packaging. Should be very careful in choosing a package, because it affects the safety and security of your goods. Some species do not require special packaging and other prohibited for carriage in bulk. Do not forget the special packaging - it's not just plastic or cardboard, this is a special certified labeling.
Types of packaging:
- Biomedical packaging;
- Import packing for all classes of dangerous goods.
Domestic combination packagings:
- Fibrokarton 4G;
- Inner packagings IP2 and IP1;
- Steel barrels and drums 1A1 and 1A2 for the transport of dangerous goods.
