Trasporto su strada di merci pericolose effettuate conformemente alle disposizioni del trattato di paesi europei per il trasporto internazionale di merci pericolose su strada (ADR.)

Ogni classe di merci pericolose in base alla loro proprietà fisico-chimiche, specie, e il grado di pericolo durante il trasporto sono divisi in sotto-classi, categorie e gruppi (secondo la classificazione ADR del contratto).

CLASSE 1 – materiale esplosivo la cui proprietà potrebbe esplodere e causare un incendio con effetto esplosivo, così come i dispositivi contenenti materie esplosive ed esplosive destinate a produrre effetti pirotecnici;

Divisione 1.1 – Esplosivi e sostanze pirotecniche e di prodotti a rischio di esplosione in massa quando l’esplosione copre istantaneamente l’intero carico;
Divisione 1.2 – Esplosivi e sostanze pirotecniche e gli oggetti non esplodono di massa;
Divisione 1.3 – Esplosivi e sostanze pirotecniche e oggetti comportanti un rischio d’incendio con un piccolo effetto esplosivo o senza di essa;
Divisione 1.4 – Esplosivi e sostanze pirotecnici e articoli che presentano un leggero pericolo durante il trasporto solo in caso di accensione o innesco, che non è la distruzione di dispositivi e pacchetti;
Divisione 1.5 – Esplosivi con un rischio di esplosione in massa la cui sensibilità è che l’inizio di trasporto o di passaggio dalla combustione alla detonazione è improbabile;
Divisione 1.6 – prodotti contenenti sostanze detonanti poche sensibili probabilità frantumi di massa e basso livello d’innesco accidentale;

CLASS 2 – gases, including compressed, dissolved under pressure gases and vapours that are in compliance to at least one of the following conditions:
– absolutely pressure of vapours by the temperature 50 degrees.
– critical temperature less than 50 degrees.

According to physical condition gases are divided into:
– compressed , that critical temperature is less than –10 degree;
– liquefied gas, that critical temperature is equals or more than –10 degrees, but less than 70 degrees;
– dissolved under pressure;
– liquefied under cooling;
– aerosol and compressed gas that are under action of special regulation.

• Subclass 2.1. – non-flammable gases
  
• Subclass 2.2. – non-flammable toxic gases
  
• Subclass 2.3. – highly inflammable gases
  
• Subclass 2.4. – highly inflammable toxic gases
  
• Subclass 2.5. – chemically unstable toxic gases

CLASS 3 – highly inflammable liquid, mixes of liquids and liquids, contained rough substances in it and suspension, that release highly inflammable vapours, that has the temperature of flash in close capsule 61 degrees and lower.

• Subclass 3.1. – highly inflammable liquids with low temperature of liquid flash, that has the temperature of flash in close capsule lower than –18 degrees, or that has the temperature of flash in aggregate with another dangerous features, except highly inflammable;
  
• Subclass 3.2. – highly inflammable liquids with average temperature of liquid flash in close capsule ranging from –18 to +23 degrees.
  
• Subclass 3.3. – highly inflammable liquids with high temperature of flash-are liquids with temperature of flash ranging from 23 to 61 degrees, including in a close capsule.

CLASS 4 – highly inflammable substances and materials (except qualified as inflammable), that can inflame during the transportation because of outer sources as a result of friction, liquid absorption, spontaneous chemical transformations and while heating;

• Subclass 4.1. – highly inflammable rough substances, that can inflame because of external influence (such as spark, flame or friction) and actively burn.
  
• Subclass 4.2. – self-ignitable substances, that in usual conditions of transportation can heat and inflame self-ignitable.
  
• Subclass 4.3. – substances that in cooperation with water can emit inflammable gases.

CLASS 5 – oxidizing agents and organic peroxides that are able easily to emit oxygen, to maintain burning process, and also in corresponding conditions or in mixtures with other substances can make self-ignition or explosion;

• Subclass 5.1. – oxidizing agents, that are not inflammable themselves, but promote the inflammination of other substances and emits oxygen while burning, that makes the flame more intensive.
  
• Subclass 5.2. – organic peroxides, that in majority of cases are combustible, can act as oxidizing agents and dangerous in action with another substances. The majority of them are easily inflammable and sensitive to knocks and frictions
  

CLASS 6 – toxic and infectious substances, that can be the reason of death, poisoning or deceases that while coming inside of the organism or while contact with skin and mucous tunic.

• Subclass 6.1. – toxic substances, that can be the reason of poisoning while breathing the vapours or dust, hitting inside or in contact with skin.
  
• Subclass 6.2. – substances and materials, containing pathogenic bacteria, that are dangerous for people and animal.

CLASS 8 caustic and corrosive substances, that damage the skin, damaging of mucous membrane of eyes and breathing passages, metal corrosion and damages of vehicles, buildings or cargoes; also can be the reason of flame while interaction with organic materials and several chemical substances.

• Subclass 8.1. – acid;
  
• Subclass 8.2. – alkali;
  
• Subclass 8.3. – different caustic and corrosion substance.
  

• Subclass 9.1. – rough and liquid burning substances and materials, that in compliance to their features are not referred to 3rd and 4th classes of dangerous, but in special conditions can be dangerous and inflammable (inflammable liquids with the temperature of flash ranging from +61 degrees to +100 degrees in clause capsule and other similar materials);
  
• Subclass 9.2. – Substances those become caustic and corrosive under special condition.
