Hasard Class


Class 1


Explosive materials whose properties can explode, cause a fire with explosive action, as well as devices containing explosives and explosive designed to produce a pyrotechnic effect;


1.1 explosive and pyrotechnic substances and products with a mass explosion hazard when the explosion instantly covers the entire load;

1.2 explosive and pyrotechnic substances and articles that are not mass explosion hazard;

1.3 explosive and pyrotechnic substances and articles which have a fire hazard with a small explosive action or without;

1.4 explosive and pyrotechnic substances and articles which present a minor explosion hazard 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 when transporting initiation or transition from burning to detonation is unlikely;

1.6 Products containing extremely insensitive detonating substances without exploding mass and characterized by a low probability of accidental initiation;

The main danger - the explosion.


Class 2


Gases, compressed, liquefied cooled and dissolved under pressure, meet at least one of the following conditions are met: absolute vapor pressure at a temperature of 50C or higher is equal to 3 kgf / cm ZOO kPa); critical temperature below 50 ° C; short, critical temperature below -10 ° C; liquefied, the critical temperature is equal to or higher than 10C but below 70C; liquefied, the critical temperature is at or above 70 ° C; dissolved under pressure; Liquefied hypothermia; aerosols and compressed gases that fall under special regulations.


2.1 Flammable gases;

2.2 non-flammable and poisonous gases;

2.3 Toxic gases;

2.4 Flammable toxic gases;

2.5 The chemically unstable;

2.6 The chemically unstable toxic.

There is the main danger, as there are various dangerous properties.


Class 3


Flammable liquids, mixtures of liquids and liquids containing solids in solution or suspension, which emit flammable vapors having a flash point in closed crucible 60C and below;


3.1 Flammable liquids with a low flash point and liquid having a flash point in closed crucible below minus 18C or with a flash in combination with other hazardous characteristics, in addition to flammability;

3.2 Flammable liquids with medium flash point - a liquid with a flash point in closed crucible from minus 18 to plus 23 ° C;

3.3 Flammable liquids with a high flash point - a liquid with a flash point of 23 to 60C inclusive in a closed crucible.

The main danger - fire.


Class 4


Flammable materials and substances (other than those classified as explosives), which during transportation easily ignited by an external source of ignition through friction, moisture absorption, spontaneous chemical reactions, and heating;


4.1 Flammable solids, can easily be ignited by brief exposure to external sources of ignition (spark, flame or friction), and actively burning;

The main danger - the danger of fire and more - thermal instability - explosion.


4.2 pyrophoric substances, which under normal conditions of transport can spontaneously heat and ignite;

The main danger - spontaneous combustion.


4.3 Substances which emit flammable gases. The main danger - flammable gases (eg, calcium carbide).


Class 5


Oxidizing agents and organic peroxides which can easily release oxygen to support combustion, and can, in appropriate circumstances, or in admixture with other substances, to cause spontaneous ignition and explosion;


5.1 oxidizing agents, which themselves are not combustible, but contribute to the easy flammability of other substances and release oxygen during combustion, thereby increasing the intensity of the fire;

The main danger - oxidation.


5.2 Organic peroxides, which in most cases are combustible, may act as oxidizing agents and dangerous to interact with other substances. Many of them are easy to light and sensitive to shock and friction.

The main danger - thermal instability, that is, during the heating of explosion.


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 cause poisoning by inhalation (vapor, dust), ingestion or skin contact;

The main danger - toxic.


6.2 Substances and materials containing pathogens dangerous to humans and animals.

The main danger - infection.


Class 7


Radioactive substances with specific activity of more than 70 kBq / kg. The main danger - a strong radioactivity.


Class 8


Caustic and corrosive substances that cause damage to the skin, mucous membranes of 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 Alkalis;

8.3 Miscellaneous caustic and corrosive substances.

The main danger - bite (corrosiveness).


Class 9


Substances with relatively low risks in the transportation are not preceded by one of the previous classes, but require application to them of certain rules of transportation and storage;


9.1 Solid and liquid combustible substances and materials whose properties do not belong to the 3 rd and 4 th grade, but under certain conditions can be a fire hazard (flammable liquids with a flash point of +60 ° C to +100 ° C in closed vessel, fiber, and other similar materials);

9.2 The substances that become caustic and corrosive under certain conditions.

In this class there is a dominant main danger (eg plastic, which when burned releases a strong poison - dioxin).
