The maximum quantity of organic peroxides of Class 5.2 and self-reactive substances of Class 4.1 of

(Reserved)
Handling and stowage
Where appropriate the vehicle or container shall be fitted with devices to facilitate securing and
handling of the dangerous goods. Packages containing dangerous substances and unpackaged
dangerous articles shall be secured by suitable means capable of restraining the goods (such as
fastening straps, sliding slatboards, adjustable brackets) in the vehicle or container in a manner that
will prevent any movement during carriage which would change the orientation of the packages or
cause them to be damaged. When dangerous goods are carried with other goods (e.g. heavy machinery
or crates), all goods shall be securely fixed or packed in the vehicles or containers so as to prevent the
release of dangerous goods. Movement of packages may also be prevented by filling any voids by the
use of dunnage or by blocking and bracing. Where restraints such as banding or straps are used, these
shall not be over-tightened to cause damage or deformation of the package1. The requirements of this
paragraph are deemed to be complied with if the cargo is secured in accordance with standard
EN 12195-1:2010.
1 Guidance on the stowage of dangerous goods can be found in the European Best Practice Guidelines on
Cargo Securing for Road Transport published by the European Commission. Other guidance is also available from
competent authorities and industry bodies.
Packages shall not be stacked unless designed for that purpose. Where different design types of
packages that have been designed for stacking are to be loaded together, consideration shall be given
to their compatibility for stacking with each other. Where necessary, stacked packages shall be
prevented from damaging the package below by the use of load-bearing devices.
During loading and unloading, packages containing dangerous goods shall be protected from being
damaged.
NOTE: Particular attention shall be paid to the handling of packages during their preparation for
carriage, the type of vehicle or container on which they are to be carried and to the method of loading
or unloading, so that accidental damage is not caused through dragging or mishandling the packages.
The provisions of 7.5.7.1 also apply to the loading, stowage and removal of containers, tankcontainers,
portable tanks and MEGCs on to and from vehicles.
Members of the vehicle crew may not open a package containing dangerous goods.
Loading of flexible bulk containers
Flexible bulk containers shall be carried within a vehicle or container with rigid sides and ends that
extend at least two-thirds of the height of the flexible bulk container. The vehicles used for carriage
shall be equipped with a vehicle stability function approved in accordance with ECE Regulation
No. 132.
NOTE: When loading flexible bulk containers in a vehicle or container particular attention shall be
paid to the guidance on the handling and stowage of dangerous goods referred to in 7.5.7.1 and to the
IMO/ILO/UNECE Code of Practice for Packing of Cargo Transport Units (CTU Code).
Flexible bulk containers shall be secured by suitable means capable of restraining them in the vehicle
or container in a manner that will prevent any movement during carriage which would change the
position of the flexible bulk container or cause it to be damaged. Movement of the flexible bulk
containers may also be prevented by filling any voids by the use of dunnage or by blocking and
bracing. Where restraints such as banding or straps are used, these shall not be over-tightened to cause
damage or deformation to the flexible bulk containers.
Flexible bulk containers shall not be stacked.
Cleaning after unloading
If, when a vehicle or container which has contained packaged dangerous goods is unloaded, some of
the contents are found to have escaped, the vehicle or container shall be cleaned as soon as possible
and in any case before reloading.
If it is not possible to do the cleaning locally, the vehicle or container shall be carried, with due regard
to adequate safety, to the nearest suitable place where cleaning can be carried out.
Carriage is adequately safe if suitable measures have been taken to prevent the uncontrolled release of
the dangerous goods that have escaped.
Vehicles or containers which have been loaded with dangerous goods in bulk shall be properly
cleaned before reloading unless the new load consists of the same dangerous goods as the preceding
load.
