Dangerous goods are goods that are harmful (to the environment, people and animals) and require special attention during transportation. The company Trans-Tur provides services for the transportation of dangerous goods in the territory Ukraine, Europe, CIS. To order the service, contact us in any way convenient for you in the contacts section.
Useful information to know about similar types of cargo
To reduce the negative impact and safely transport dangerous goods, they are placed in containers, tanks, boxes with increased density, etc. Also, for safety, trucks that transport explosive gases are designed so that the exhaust pipe does not pass near the container to exclude the possibility of heating. The vehicle is marked with special signs.
Cargo danger signs
All detailed instructions are available in three documents:
-
ADR is an international document on the transport of dangerous goods between countries.
-
POGAT applies exclusively to road transport.
-
GOST 19433-88 - classification of dangerous goods.
In addition, dangerous goods are divided into hazard types:
Cargo is divided into ADR (ADR) classes. All rules are published in ADR.
Classes of dangerous goods
1. Explosive chemical products, as well as mechanisms.
They emit a large amount of heat or gases under high pressure. Heat, light and sound may be present without detonation. Explosive products can be based on the explosive chemical elements that make up their composition.
2. Gases. The degree of danger varies:
-
They can sustain combustion better than oxygen.
-
Ignite quickly at temperatures up to 20 degrees Celsius.
-
May be poisonous to humans.
Corrosive effect is damage to the mucous membrane of the eye or a negative effect on the skin. To indicate the degree of danger, a car that transports hazardous substances has a special sign with the letters:
-
A - gas prevents breathing,
-
O - promotes combustion,
-
F - danger of fire, propane,
-
T - poisonous substances, poison.
Also, types can be combined. You can see on trucks both two and three letters at the same time, depending on the properties of the substance.
3. Explosive liquids.
These also include solid chemical formulations brought to a liquid state and kept in this form during transportation.
4. Flammable substances and materials
4.1. The class includes:
-
Solid chemical elements, as well as mechanisms that lead to an explosion. Solids are easily ignited, ignited by friction or in contact with other chemical elements or reagents. So, sodium as a powder can more actively react with moisture, catching fire. They carry a particular danger because the addition of water does not extinguish the flame, along with carbon dioxide. On the contrary, reacting with water, sodium only ignites more strongly.
-
Chemical elements in a solid and liquid state that are capable of producing a reaction without additional catalysts.
-
Cargoes that remain inactive thanks to dihydrogen monoxide.
-
Polymerizing weights without additional catalysts can actively release heat, producing polymers.
4.2 Self-igniting substances
They are also called pyrophoric. They are characterized by the fact that they enter into an active reaction with air, leading to an explosion, not immediately. And after large intervals of time from the beginning of the reaction. And at the same time, the amount of cargo should be large.
These include iron sulfide and mixtures with its participation. It ignites on contact with oxygen. Therefore, the entire surface of the container is carefully disinfected with steam before loading. Or the tank is filled with water, and then it is poured out at a speed sufficient to clear the remaining substances.
4.3 Substances releasing no flammable gases during contact with water.
After being released, the gas is able to react with air, which leads to an explosion. Some gases of this type require a spark to ignite. Therefore, the gas cloud is able to spread over a long distance until it finds a source of fire to react.
So, if sodium gets into water, it releases a lot of heat and hydrogen gas, which ignites instantly. Cabride, which is used to extract rubber. But on contact with water, it releases C2H2 gas, which is capable of spontaneous combustion.
5. Oxidizing agents and organic peroxides
5.1 Oxidizers
They don't burn. However, they support combustion much more actively than oxygen. An example is hydrogen peroxide and bleach. For example, when hydrogen peroxide and sodium are combined, combustion will continue until both elements burn out without residue.
5.2 Organic self-igniting elements.
They can explode and ignite upon friction, elevated temperature, contact with other elements and impurities. Can explode in a closed box. Therefore, either a solvent is added to them, or they are placed in a special container. Therefore, peroxides should be transported only in vehicles with artificial temperature stabilization.
Especially flammable - chlorine trifluoride, oxygen fluoride, etc.
6. Poisonous and infectious substances
6.1 Toxic Substances
The harmfulness of such products for animals has been experimentally proven. Their harmful effects are manifested by inhalation of vapors, ingestion and even contact with the skin. Therefore, the loading and unloading of such radicals must be carried out in special suits and in compliance with safety rules.
6.2 Infectious substances
Infectious substances are substances that contain pathogenic microorganisms or infectious agents. For example, prions.
-
“Biological products” contain pathogens and agents. But they are either distributed to produce a vaccine, or they themselves are a vaccine. They also require a certain temperature regime and an increased level of packaging tightness.
-
“Crops” are artificially grown pathogens that have not had contact with living organisms and are bred solely for research purposes.
-
“Medical/clinical waste” waste left after the treatment of people or animals.
-
“Samples taken from humans and animals” - this can be taken from blood samples, epithelial samples, as well as excrement, saliva and sweat.
These are the Ebola virus, Malaria, etc.
7. Radioactive materials
These are the elements that spread alpha, beta and gamma rays.
The consequence of their impact on the body can be cancer, leukemia, hepatitis, etc. Must be stored and transported in containers that prevent their radioactive impact on the environment: Potassium, Calcium, Vanadium, Germanium, etc.
8. Corrosive substances
These substances negatively affect the skin. mucous membrane of the eye and mouth. They also negatively affect all elements that corrode due to contact with moisture.
This includes batteries, electrolytes, etc.
9. Other products
These include substances that are harmful to humans, animals and the environment, although they do not fit into any of the eight classes. They have a low degree of harm. However, they require careful storage and transportation under certain conditions.
How to determine the number for dangerous goods?
According to the class, subsidiary risk and type of packaging, the number assigned by the UN is established. The United Nations, at one of its meetings, compiled a complete list of hazardous substances that must be identified for control. This allows you to develop special rules of behavior for security purposes.
To identify a cargo by name, you can search for it using three parameters:
-
Name of the main substance.
-
Name of the cargo according to its commercial name.
-
Search by synonyms.
Safety and type of packaging of dangerous goods
The label also includes an indication of how the packaging protects the product from the impact on others. The shipper is responsible for the safety of the packaging. Most often, this is a container up to 3000 liters. It can be unparsed or parsed. The second type is called “combined”.
-
X is the most reliable type of packaging, which is divided into three groups and marked with Roman numerals.
-
Y - the second degree of reliability, medium. It is divided into two types.
-
Z - satisfactory type of packaging.
