Description and markings used on transport tanks such as tankers".We have to offer a comprehensive service related to the production, assembly and delivery of chemical-resistant tanks and equipping them with emptying and filling stations. The scope of our work includes: unloading and reloading stations, UDT chemical resistant tanks, pipelines and transfer to production lines. We provide full support in the investment process such as notification and agreement with the TDT Transport Technical Supervision unit. We do not supply the NO stations themselves. We carry out the design of the UNO loading station and the NO unit for hazardous liquids. We store them in our tanks for, among others, sulphuric acid, nitric acid, hydrochloric acid, water: ammoniacal, oxidised, sodium hypochlorite, soda lye and others.

Scope of work for UNO systems

  • tailoring of requirements for a given investment/project
  • design of UNO loading station
  • agreement and preparation of technical and registration documentation for the TDT unit
  • delivery of UNO equipment and installation of fittings on site

What is the filling process for storage tanks?

Filling takes place with additional arrangements and operations (especially in TIR tankers). Each filling and emptying equipment station (UNO) operates with a system of valve, pipe, hose and signal connections. The aforementioned installations and fittings are subject to the Regulation of the Minister of Transport of 20 September 2006 on the technical supervision conditions to be met by equipment for filling and emptying transport tanks (as amended) in agreement with and notification to the TDT unit.

NO equipment for unloading tanks (UNO station)

It is used for the unloading and loading of transport tanks with hazardous liquid raw materials (corrosive, poisonous, flammable). The purpose of this equipment is to safely ensure the process of emptying and filling tankers into storage tanks for liquid raw materials. The stations are equipped with a multitude of electronic and mechanical facilities to ensure high safety for both the installation itself and the personnel operating the station. The necessity of using appropriate installation safety devices during the unloading of liquid hazardous raw materials from tank trucks is stipulated in the Regulation of the Minister of Transport of 20 September 2006. The use of equipment and process safeguards in accordance with legal requirements is subject to notification to and agreement with the TDT unit.

Safeguards applied according to the hazard category building NO:

  • Automatic disconnection valve
  • Control cabinet with acoustic signalling of leakage
  • Measurement:
  • temperature and pressure of the medium
  • emissions and leaks
  • Connector:
  • emergency disconnection
  • dry-cutting

The most important legislation underpinning the technical supervision of equipment:

  • Act of 21 December 2000 on technical supervision
  • Regulations of:
  • 26 November 2010. Minister for the Economy
  • 7 December 2012. of the Council of Ministers
  • 21 May 2019. Minister of Entrepreneurship and Technology

When preparing the NO device for testing, the requirements of the device's operating instructions must be taken into account.

Classification and labelling in transport:

  • ADR by road
  • ADN inland
  • Railway RID

List of dangerous goods - ADR marking

Land transport is the most common mode of transport of hazardous materials. All regulations and standards related to the carriage of goods by road are defined by the European Agreement ADR (The European Agreement concerning the International Carriage of Dangerous Goods by Road). It is valid not only in Europe, but also worldwide. When importing goods from China to Poland, it is necessary to bear in mind the acts of local law, i.e. the Law on the Carriage of Dangerous Goods and the Law on Weapons and Ammunition. Packages containing dangerous goods must be appropriately labelled. The orange label bears the hazard identification number. This is usually two or three digits, preceded by a letter and a four-digit UN number. ADR stickers, on the other hand, are in the shape of a square rotated by 45 degrees. The markings should be located in a prominent position.

Miscellaneous hazardous materials and objects

Present a hazard during transport - other than the materials specified in the other classes.

  • M1 - fine dust which can be hazardous to health if inhaled
  • M2 - can form dioxins during a fire
  • M3 - emit inflammable vapours
  • M4 - lithium batteries
  • M5 - emergency items
  • M6-M8 - environmentally hazardous
  • M9-M10 - elevated temperature
  • M11 - hazard in transit not corresponding to the definitions of other classes

RID - Transport of dangerous goods by rail

This is a regulation for the international carriage of dangerous goods by rail. Appropriate safety precautions must be provided that are appropriate to the characteristics and extent of the hazards.

  1. Dangerous reactions include:
    • production of unstable and corrosive materials
    • dangerous increase in pressure,
    • release of inflammable, suffocating, oxidising or toxic gases
    • generating large amounts of heat or combustion
  1. For labelling, similar boards are used to those of the ADR. They are orange in colour, with the hazard number at the top and the UN code at the bottom, identifying the specific substance. They are placed on the sides of tanks or containers.
  2. The upper part of the board presents a two- or three-digit number indicating the risk of the load being carried:
    • 2 - gas emissions
    • 3 - self-heating or liquid flammable substance
    • 4 - flammable solid
    • 5 - oxidising properties
    • 6 - toxic or infectious
    • 7 - radioactive activity
    • 8 - corrosive
    • 9 - danger of spontaneous and violent reaction
  1. If the load can only cause one of the hazards, a '0' is added after the figure in question. If the hazard is very severe, then this digit is doubled.
  2. A number preceded by the letter 'X' - indicates that in a fire situation, the fire must not be extinguished with water.
  3. UN code number at the bottom with which the substance being transported is identified.

For example:

"1789" - acid: hydrochloric

"1805" - phosphoric

"1830" - sulphur with a concentration of more than 51%

"2031" - nitrogenous with a concentration below 55%

"1202" - fuel oils

"1203" - petrol

"1223" - paraffin

"1230" - methanol

"1266" - flammable perfume products

"1268" - petroleum distillates

UNO machine operation - filling machine

Course in filling and emptying transport tanks (tankers)

We provide training for individuals or companies. In the case of organised groups, we will carry out training throughout Poland if the training client provides stationary equipment for filling and emptying transport tanks with a current TDT examination for practical classes. We carry out all the formalities related to registering students for examinations and setting an examination date by the Transport Technical Supervision. We have the option of holding training courses at weekends.

What does a pouring course look like?

It is made up of a theoretical and practical part, which ends with a state examination before the Transport Commission of the Technical Supervisory Authority.

What does tank filling and emptying training cover?

  • general information on the physico-chemical properties of dangerous goods RID/ADR.
  • knowledge of dangerous goods carried in RID/ADR transport tanks
  • a set of rules according to the technical supervision of NO equipment and transport vessels
  • types of equipment for filling and emptying transport tanks, including the operation and inspection of such equipment
  • health and safety and fire regulations.
  • environmental protection
  • first aid
