Vehicles and containers containing substances used for cooling or conditioning purposes (other than
fumigation) during carriage are not subject to any provisions of ADR other than those of this section.
When dangerous goods are loaded in vehicles or containers containing substances used for cooling or
conditioning purposes any provisions of ADR relevant to these dangerous goods apply in addition to
the provisions of this section.
Persons engaged in the handling or carriage of vehicles and containers containing substances used for
cooling or conditioning purposes shall be trained commensurate with their responsibilities.
Packages containing a coolant or conditioner
Packaged dangerous goods requiring cooling or conditioning assigned to packing instructions P203,
P620, P650, P800, P901 or P904 of 126.96.36.199 shall meet the appropriate requirements of that packing
For packaged dangerous goods requiring cooling or conditioning assigned to other packing
instructions, the packages shall be capable of withstanding very low temperatures and shall not be
affected or significantly weakened by the coolant or conditioner. Packages shall be designed and
constructed to permit the release of gas to prevent a build-up of pressure that could rupture the
packaging. The dangerous goods shall be packed in such a way as to prevent movement after the
dissipation of any coolant or conditioner.
Packages containing a coolant or conditioner shall be carried in well ventilated vehicles and
containers. Marking according to 188.8.131.52 is not required in this case.
Ventilation is not required, and marking according to 184.108.40.206 is required, if:
- gas exchange between the load compartment and the driver’s cab is prevented; or
- the load compartment is insulated, refrigerated or mechanically refrigerated equipment, for
example as defined in the Agreement on the International Carriage of Perishable Foodstuffs
and on the Special Equipment to be Used for such Carriage (ATP) and separated from the
NOTE: In this context "well ventilated" means there is an atmosphere where the carbon dioxide
concentration is below 0.5% by volume and the oxygen concentration is above 19.5% by volume.
Marking of packages containing a coolant or conditioner
Packages containing dangerous goods used for cooling or conditioning shall be marked with the name
indicated in Column (2) of Table A of Chapter 3.2 of these dangerous goods followed by the words
"AS COOLANT" or "AS CONDITIONER" as appropriate in an official language of the country of
origin and also, if that language is not English, French or German, in English, French or German,
unless agreements concluded between the countries concerned in the transport operation provide
The marks shall be durable, legible and placed in such a location and of such a size relative to the
package as to be readily visible.
Vehicles and containers containing unpackaged dry ice
If dry ice in unpackaged form is used, it shall not come into direct contact with the metal structure of a
vehicle or container to avoid embrittlement of the metal. Measures shall be taken to provide adequate
insulation between the dry ice and the vehicle or container by providing a minimum of 30 mm
separation (e.g. by using suitable low heat conducting materials such as timber planks, pallets etc).
Where dry ice is placed around packages, measures shall be taken to ensure that packages remain in
the original position during carriage after the dry ice has dissipated.
