General safety measures

The participants in the carriage of dangerous goods shall take appropriate measures according to the
nature and the extent of foreseeable dangers, so as to avoid damage or injury and, if necessary, to
minimize their effects. They shall, in all events, comply with the requirements of ADR in their
respective fields.

When there is an immediate risk that public safety may be jeopardized, the participants shall
immediately notify the emergency services and shall make available to them the information they
require to take action.

ADR may specify certain of the obligations falling to the various participants.
If a Contracting Party considers that no lessening of safety is involved, it may in its domestic
legislation transfer the obligations falling to a specific participant to one or several other participants,
provided that the obligations of 1.4.2 and 1.4.3 are met. These derogations shall be communicated by
the Contracting Party to the Secretariat of the United Nations Economic Commission for Europe
which will bring them to the attention of the Contracting Parties.
The requirements of 1.2.1, 1.4.2 and 1.4.3 concerning the definitions of participants and their
respective obligations shall not affect the provisions of domestic law concerning the legal
consequences (criminal nature, liability, etc.) stemming from the fact that the participant in question is
e.g. a legal entity, a self-employed worker, an employer or an employee.

Obligations of the main participants

NOTE 1: Several participants to which safety obligations are assigned in this section may be one and
the same enterprise. Also, the activities and the corresponding safety obligations of a participant can
be assumed by several enterprises.
NOTE 2: For radioactive material, see also 1.7.6.


The consignor of dangerous goods is required to hand over for carriage only consignments which

empty uncleaned tanks are closed and present the same degree of leakproofness as if they were

If the consignor uses the services of other participants (packer, loader, filler, etc.), he shall take
appropriate measures to ensure that the consignment meets the requirements of ADR. He may, 
however, in the case of (a), (b), (c) and (e), rely on the information and data made available
to him by other participants.

transport in a manner at least equivalent to that of paper documentation;
(c) Ascertain visually that the vehicles and loads have no obvious defects, leakages or cracks,
missing equipment, etc.;
(d) Ascertain that the deadline for the next test for tank-vehicles, battery-vehicles, demountable

made available to him by other participants.

shall not forward the consignment until the matter has been rectified.

If, during the journey, an infringement which could jeopardize the safety of the operation is observed,
the consignment shall be halted as soon as possible bearing in mind the requirements of traffic safety,
of the safe immobilisation of the consignment, and of public safety. The transport operation may only
be continued once the consignment complies with applicable regulations. The competent
