Yes, all IBC approved containers - such as the QUADRO-C with a volume of 700 litres or more - must be tested on a recurring basis according with ADR. The situation is different with containers approved as drums or packaging such as the CONTY-B or the CONTY-ECO. These are not subject to the obligation to carry out recurring inspections. Other possibly required tests such as UVV (Waste Catalogue Ordinance), explosion protection for petrol solutions, etc. shall also be carried out under the operator’s responsibility at the prescribed intervals.

No. Plastic or combination IBCs with a plastic inner container may be used according to the ADR paragraph 4.1.1.15 for a maximum of five years. But: the plastic container can be replaced by means of repair by a recognised qualified company and be used for another five years after a subsequent inspection. 

No! As long as the required inspections have been carried out, IBCS as well as drums and packaging are approved for transport for an unlimited period of time.

According to the ADR, inspections must be carried out at intervals of no more than 2.5 years from e date of manufacture

.

This is regulated in rule BAM-GGR 002 on hazardous goods issued by the Federal Institute for Materials and Research (BAM). This defines who is authorised to carry out repeat checks and inspections on IBCs.

Inspection after  2 ½ years
By a level II inspection body registered with the BAM, pursuant to BAM-GGR 002 – Part B, Paragraphs B 1.2.1, B 2.1 and B 3.1

Inspection after  5 years
By a level I inspection body registered with the BAM, pursuant to BAM-GGR 002 – Part A, Paragraphs A 1.2.1, A 2.1 and A 3.1

Details are defined in ADR/RID sections 6.5.4.4. and 6.5.6.7. These include the following tasks:
 
Inspection after 2 ½ years

• Inspection of the exteernal condition
• Inspection of the identification marking
• Testing the function of the operating equipment
• Leak test using air at 0.2 bar excess pressure

 
Inspection after 5 years

• Scope of the inspection after 2 ½ years
• Checking concordance with the model type
• Internal inspection

Make sure that the labelling and identification marks on the container are complete and legible. As long as goods are transported under "simplified conditions" (without exceeding the permitted limits according to ADR section 1.1.3.6, 1000 points rule), they must only be accompanied by one 2 kg fire extinguisher and a shipping document. Please bear in mind: It goes without saying that the mandatory inspections have been carried out according to schedule. Even the container itself must be intact and all openings on the container tightly sealed.

Mobile tanks that are approved as packaging or IBCs may be transported under “simplified conditions”. This is always possible if the permitted limits (1000 points rule) specified in ADR section 1.1.3.6 are not exceeded. In case of transport under "simplified conditions", specific ADR regulations do not need to be observed.

Here are the most important regulations at a glance

• the requirements regarding the vehicle and its equipment. In detail: No orange warning signs in the front and rear!
• Special training of the vehicle driver. In detail: No ADR (hazardous goods driver) licence!

The permitted limit for diesel is 1000 litres (= 1000 points), for petrol 333 litres (= 999 points) per transport unit (vehicle with/without trailer). Provided that no other hazardous goods are transported. Larger quantities may, of course, also be transported with approved containers, however, all ADR regulations for transporting hazardous goods must then be complied with.

A shipping document is ultimately nothing more than a delivery note, on which, however, the following mandatory information must be present in accordance with ADR Section 5.4.1.
The information in [brackets] are for diesel, as an example:

The shipping document is not bound to any layout and the position and order of the information may be freely selected. The information about a), b), c), d) and k) however, must be specified in this order without any additional information, i.e. for diesel:

UN 1202 DIESEL FUEL, 3, III, (D/E)

Pursuant to ADR Chapter 5.2, transport items (packaging and IBCs) must be marked and labelled to enable identification of the material being transported from the outside. In case of IBCs with a capacity of more than 450 litres, this must be done on two opposite sides. In case of IBCs with a capacity of up to 450 litres as well as packaging, this is only required on one side.

The following labelling is an example for transporting petrol:

In addition, substance-related safety information according to GHS must be attached once. An IBC properly prepared for transport could thus look like this (Kraftstoffcontainer Kennzeichnung - Download (pdf, 274 KB)).
Incidentally: each Rietberg IBC/packaging includes a set of stickers for initial marking.

Our tank containers may be used for the transportation and storage of flammable liquids. If you want to use our models as discharge containers at the location of storage, these must not be refilled at the same location. This must be done at a filling area such as a fuel station. In addition, filling the container must always be done through the dedicated filler neck either from a tanker vehicle with connection of the fill limit indicator or at a fuel station or filling station for private consumption with automatically locking pump nozzle.

Rietberg fuel containers are largely maintenance-free. Irrespective of the inspections according to ADR, however, containers and equipment have to be regularly checked for potential damage. The fuel container may only be used in a technically faultless condition. The leakage indicator on a double-walled fuel container, any limit indicator present as well as a potentially fitted pump require inspection according to the relevant operating instructions.

Diesel tank systems with a capacity of more than 1,000 litres require inspection by a qualified professional prior to commissioning. There is no need for the inspection, however, if the system was installed by a qualified company.

A diesel tank system up to a capacity of 10,000 litres does not need to be repeatedly inspected (5 m³ in water protection areas). Local authorities may specify further requirements, however.

Double-walled units within the meaning of AwSV Section 2 (17) consist of two independent walls. The space between them is equipped with a leakage indicator system, which shows leaky points on the inner and outer walls. All Rietberg fuel tank systems are double-walled units. This also applies, incidentally, to all Rietberg fuel containers consisting of two walls. Containers in or on a collection tray, on the other hand, are not double-walled units according to AwSV.

According to TRwS 781 , a filling area is required for filling the container as well as for fuelling the vehicles. For units below 1000 litres of storage capacity, simplified conditions apply. Rietbergwerke offer a ready-made solution with the fuel filling bay .

• For the size of the filling area, the following aspects must be taken into account:

  a) Filling of the storage container
  The working area for filling covers the horizontal hose guide line around the connection fitting of the storage container plus 2.5 m in all directions.

  b) Delivery – fuelling of vehicles
  Here, the rule of discharge hose length including nozzle plus 1 m in all directions applies. The respective circle can be reduced to a semi-circle by means of a splash guard wall. For this purpose, a splash guard wall with a minimum height of 1 m and sufficient width is required.

Rietberg fuel tank systems are largely maintenance-free. Containers and equipment, on the other hand, must be regularly checked for potential damage and the fuel tank system may only be used in perfect condition. The leakage indicator and any limit indicator present as well as a potentially fitted pump require inspection according to the operating instructions.

Yes, inspection by a qualified professional prior to commissioning is required.

According to operational safety regulations, inspections must be repeated at intervals of five years.

Double-walled units within the meaning of AwSV Section 2 (17) consist of two independent walls. The space between them is equipped with a leakage indicator system, which shows leaky points on the inner and outer walls. All Rietberg fuel storage tanks are double-walled units. This also applies, incidentally, to all Rietberg fuel containers consisting of two walls. Containers in or on a collection tray, on the other hand, are not double-walled units according to AwSV.

According to TRbF20, the storage of flame-retardant liquids of hazard class AIII (flash point above 55°C) and of non-flammable substances does not require notice nor approval.

For the size of the filling area, the following aspects must be taken into account:

a) Filling of the storage container
The working area for filling covers the horizontal hose guide line around the connection fitting of the storage container plus 2.5 m in all directions.

b) Delivery – fuelling of vehicles
Here, the rule of discharge hose length including nozzle plus 1 m in all directions applies. The respective circle can be reduced to a semi-circle by means of a splash guard wall. For this purpose, a splash guard wall with a minimum height of 1 m and sufficient width is required.

When designing the filling area, the retention capacity must also be taken into account - the following applies here:

a) Filling the storage container
For filling of the storage container, the retention capacity is defined by the fuel volume that may be discharged within the time until automatic activation of safety equipment.
This means that if a filling hose protection mechanism (ASS) is used, a retention capacity of 100 litres is required.
If equipment with an attention button and emergency off switch (ANA) is used when filling, a retention capacity of 900 litres is required.

b) Delivery – fuelling of vehicles
For delivery, the maximum retention capacity is calculated from the maximum pumping capacity of the fuel pump in 3 minutes, i.e. a nominal pumping capacity of 50 litres/min leads to a retention capacity of 150 litres.

The Rietberg fuel filling bay is not approved for petrol.

Rietberg fuel tank systems are largely maintenance-free. However, containers and equipment have to be regularly checked for potential damage, as the fuel tank system may only be used in perfect condition. The leakage indicator and any limit indicator present as well as a potentially fitted pump require inspection according to the relevant operating instructions.

Units with a capacity of more than 1,000 litres must be inspected by a qualified professional prior to commissioning. Up to a unit capacity of 10 m³, there is no need for the inspection as long as the unit was installed by a qualified company. Incidentally, the inspection obligations are governed in the Ordinance on Installations for the Handling of Substances Hazardous to Water (AwSV).

Units up to a capacity of 10,000 litres do not require repeated inspection (5 m³ in water protection areas). Units with a capacity of more than 10 m³ (content of all containers) require inspection by a qualified professional at intervals of five years. Local authorities may specify further requirements.

Double-walled units within the meaning of AwSV Section 2 (17) consist of two independent walls.

This also applies, incidentally, to all Rietberg fuel containers consisting of two walls. Containers in or on a collection tray, on the other hand, are not double-walled units according to AwSV.

For double-walled units within the meaning of AwSV, no collection trays are required – otherwise, the following applies:

Mixtures that may containing water-polluting substances and leak in case of damage have to be able to be retained. The collection capacity of the storage space has to correspond to the maximum volume of the substances that may leak in case of malfunctions. For units with a capacity below 1 m³ and for liquids of WGK1, no retention capacity is required.

Rietberg storage and collection containers are largely maintenance-free. However, containers and equipment have to be regularly checked for potential damage. The unit must only be used in perfect condition. The leakage indicator and any overfill protection device present as well as any other equipment parts require inspection according to the relevant operating instructions.

Yes, inspection by a qualified professional prior to commissioning is required.

Storage and collection containers for flammable substances must be inspected at intervals of 5 years.

A minimum distance of 10 m to buildings must be observed if these are not sufficiently protected against fire (F90 according to DIN 4102). In case of indoor installation, walls, ceilings and doors must be made of non-flammable building materials. Between storage spaces and neighbouring rooms, fire-resistant (F90 according to DIN 4102) partitions are required. In addition, ventilation has to permanently ensure at least a 5-fold exchange of air.
