Operation

The thickness of the walls of the shell shall not, throughout its use, fall below the minimum figure
prescribed in:
 
6.8.2.1.17 to 6.8.2.1.21.                               |                              6.8.2.1.17 to 6.8.1.20.

                                                                         
During carriage tank-containers/MEGCs shall be
loaded on the carrying vehicle in such a way as to
be adequately protected by the fittings of the
carrying vehicle or of the tank-container/MEGC
itself against lateral and longitudinal impact and
against overturning3. If the tankcontainers/
MEGCs, including the service
equipment, are so constructed as to withstand
impact or overturning they need not be protected in
this way.

 

During filling and discharge of tanks, battery-vehicles and MEGCs, appropriate measures shall be
taken to prevent the release of dangerous quantities of gases and vapours. Tanks, battery-vehicles and
MEGCs shall be closed so that the contents cannot spill out uncontrolled. The openings of bottomdischarge
tanks shall be closed by means of screw-threaded plugs, blank flanges or other equally
effective devices. After filling, the filler shall ensure that all the closures of the tanks, battery-vehicles
and MEGCs are in the closed position and there is no leakage. This also applies to the upper part of
the dip tube.
 
 
 
3 Examples of protection of shells:
- protection against lateral impact may, for example, consist of longitudinal bars protecting the shell on
both sides at the level of the median line;
- protection against overturning may, for example, consist of reinforcing rings or bars fixed transversally
in relation to the frame;
- protection against rear impact, may, for example, consist of a bumper or frame.

 

Where several closure systems are fitted in series, that nearest to the substance being carried shall be
closed first.

No dangerous residue of the filling substance shall adhere to the outside of the tank during carriage.

Substances which may react dangerously with each other shall not be carried in adjoining
compartments of tanks.
Substances which may react dangerously with each other may be carried in adjoining compartments of
tanks, when these compartments are separated by a partition with a wall thickness equal to or greater
than that of the tank itself. They may also be carried separated by an empty space or an empty
compartment between loaded compartments.

Fixed tanks (tank-vehicles), demountable tanks, battery-vehicles, tank-containers, tank swap bodies
and MEGCs may not be filled or offered for carriage after the deadline for the test or inspection
required by 6.8.2.4.2, 6.8.3.4.6 and 6.8.3.4.10 has expired.
However, fixed tanks (tank-vehicles), demountable tanks, battery-vehicles, tank-containers, tank swap
bodies and MEGCs filled prior to the date of expiry of the last periodic inspection may be carried:
(a) for a period not to exceed one month after the expiry of these deadlines;
(b) unless otherwise approved by the competent authority, for a period not to exceed three months
after the expiry of these deadlines in order to allow the return of dangerous goods for proper
disposal or recycling. Reference to this exemption shall be mentioned in the transport
document.

Empty tanks, battery-vehicles and MEGCs, uncleaned

NOTE: For empty tanks, battery-vehicles and MEGCs, uncleaned, special provisions TU1, TU2,
TU4, TU16 and TU35 of 4.3.5 may apply.

No dangerous residue of the filling substance shall adhere to the outside of the tank during carriage.

To be accepted for carriage, empty tanks, battery-vehicles and MEGCs, uncleaned, shall be closed in
the same manner and be leakproof to the same degree as if they were full.

Where empty tanks, battery-vehicles and MEGCs, uncleaned, are not closed in the same manner and
are not leakproof to the same degree as if they were full and where the provisions of ADR cannot be
complied with, they shall be carried, with due regard to adequate safety, to the nearest suitable place
where cleaning or repair can be carried out. Carriage is adequately safe if suitable measures have been
taken to ensure equivalent safety commensurate with the provisions of ADR and to prevent the
uncontrolled release of the dangerous goods.

Empty fixed tanks (tank-vehicles), demountable tanks, battery-vehicles, tank-containers, tank swap
bodies and MEGCs, uncleaned, may also be carried after the expiry of the periods established in
6.8.2.4.2 and 6.8.2.4.3 for undergoing the inspection.
