- The first class includes explosives and items containing them.
- second class - compressed gases, liquefied, cooled, dissolved under pressure.They are considered hazardous in the event that the absolute vapor pressure of 300 kPa at a temperature of 50 c.Celsius.For cooling - the critical temperature of -50 c.
- Flammable liquids, and mixtures thereof.In addition, the category of "dangerous goods" are those substances that, if the solution contains solid elements that emit vapors that can fire (flash with 61 gr. Closed cup).
- flammable substance (other than explosive) which during transportation can ignite due to the heat, friction, moisture absorption, independent chemical reactions relate to the fourth grade.
- Organic peroxides and oxidants.They emit flammable oxygen.In addition, under certain conditions, interacting with other substances can cause fire.
- Toxic substances.Classified as dangerous goods and substances that can cause infections and poisoning in humans.
- Radioactive substances (with the activity of 2 nCi / g).
- Caustic and corrosive.Anything that can cause damage to the respiratory tract, skin, eyes, and is considered to be dangerous goods.Furthermore, the substances causing corrosion of metals that could damage a vehicle other cargo, etc.
- substances are not dangerous for humans and plants, but must be handled and treated with care.
