At the moment, a lot of substances are used in industry, everyday life and other areas, which, if mishandled, pose a danger to human he alth and life. It is necessary to use and store them, observing certain established rules. In addition, dangerous goods must also be transported with appropriate safety measures.
In the latter case, compliance with the prescribed norms and rules is especially important. After all, transportation in itself is a rather responsible and complex process. The following classification of dangerous goods is provided in order to classify them according to the degree of danger.
- The first class includes explosives and items containing them.
- Second class - compressed gases, liquefied, cooled, dissolved under pressure. They are considered dangerous if the absolute vapor pressure is 300 kPa at a temperature of 50 g. on the Celsius scale. For chilled - critical temperature from -50 gr.
- Flammable liquids and their mixtures. In addition, these substances are classified as "dangerous goods" if the solution contains solid elements,emitting flammable vapors (flash at 61 degrees in a closed cup).
-
dangerous goods classification Flammable substances (other than explosives), which during transportation can ignite as a result of heating, friction, absorption of moisture, independent chemical transformations, belong to the fourth class.
- Organic peroxides and oxidizers. They give off flammable oxygen. In addition, under certain conditions, interacting with other substances, they can cause a fire.
- Poisonous substances. Substances capable of causing infection and poisoning in humans are also classified as dangerous goods.
- Radioactive substances (with activity from 2 nCi/g).
- Corrosive and corrosive. Anything that can cause damage to the respiratory tract, skin, eyes, is also considered dangerous goods. In addition, these are substances that cause rusting of metals, which can damage the vehicle, other cargo, etc.
- Substances that are not dangerous to humans and structures, but require careful and careful handling.
Such goods can be transported by any mode of transport: rail, road, sea, air. However, each case has its own specific rules. For example, sea transportation of dangerous goods, carried out both in bulk and in packages, provides for their mandatory labeling. It is permissible to use only high-quality packaging that can withstand the processes of loading and unloading. Bulk cargo,must be fixed in such a way as to prevent its spontaneous movement.
These are just the basic rules. There are plenty of others. In any case, dangerous goods must only be transported by personnel with the appropriate level of qualifications.
Summing up, we can say that the delivery of hazardous substances and items safe and sound without causing harm to people, animals and property is possible only if all established safety measures are observed and awareness of their classification.
