Limitations with respect to explosive substances and articles
Substances and quantities carried
The total net mass in kg of explosive substance (or in the case of explosive articles, the total net mass
of explosive substance contained in all the articles combined) which may be carried on one transport
unit shall be limited as indicated in the table below (see also 18.104.22.168 as regards the prohibition of
Maximum permissible net mass in kg of explosive in Class 1 goods per transport unit
Empty uncleaned packagings
Other than 1.1A
Other than 1.4S
a For the description of EX/II and EX/III vehicles see Part 9.
Where substances and articles of different divisions of Class 1 are loaded on one transport unit in
conformity with the prohibitions of mixed loading contained in 22.214.171.124, the load as a whole shall be
treated as if it belonged to the most dangerous division (in the order 1.1, 1.5, 1.2, 1.3, 1.6, 1.4).
However, the net mass of explosives of compatibility group S shall not count towards the limitation of
Where substances classified as 1.5D are carried on one transport unit together with substances or
articles of division 1.2, the entire load shall be treated for carriage as if it belonged to division 1.1.
Carriage of explosives on MEMUs
Carriage of explosives on MEMUs is only permitted subject to the following conditions:
(a) The competent authority shall authorize the transport operation within its territory;
(b) The type and quantity of packaged explosives carried shall be limited to those necessary for the
quantity of material to be manufactured on the MEMU, and in any case shall not exceed:
- 200 kg of explosives of compatibility group D; and
- a total of 400 units of detonators or detonator assemblies, or a mixture of both,
unless otherwise approved by the competent authority;
(c) Packaged explosives shall only be carried in compartments that meet the requirements of
(d) No other dangerous goods may be carried in the same compartment as the packaged
(e) Packaged explosives shall only be loaded onto the MEMU once the loading of other dangerous
goods has been completed and immediately prior to carriage;
(f) When mixed loading is permitted between explosives and substances of Class 5.1 (UN 1942
and UN 3375) the aggregate is treated as blasting explosives under Class 1 for the purposes of
segregation, stowage and maximum permissible load.
The maximum quantity of organic peroxides of Class 5.2 and self-reactive substances of Class 4.1 of
Types B, C, D, E or F and of polymerizing substances of Class 4.1 is limited to 20 000 kg per
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
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
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 126.96.36.199 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
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 188.8.131.52 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.
