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.
Marking of vehicles and containers
Vehicles and containers containing dangerous goods used for cooling or conditioning purposes that
are not well ventilated shall be marked with a warning mark, as specified in 188.8.131.52.2, affixed at each
access point in a location where it will be easily seen by persons opening or entering the vehicle or
container. This mark shall remain on the vehicle or container until the following provisions are met:
(a) The vehicle or container has been well ventilated to remove harmful concentrations of coolant
or conditioner; and
(b) The cooled or conditioned goods have been unloaded.
As long as the vehicle or container is marked, the necessary precautions have to be taken before
entering it. The necessity of ventilating through the cargo doors or other means (e.g. forced
ventilation) has to be evaluated and included in training of the involved persons.
The warning mark shall be as shown in Figure 184.108.40.206.2.
Coolant/conditioning warning mark for vehicles and containers
Insert the name indicated in Column (2) of Table A of Chapter 3.2 of the
coolant/conditioner. The lettering shall be in capitals, all be on one line and shall be at least 25 mm
high. If the length of the proper shipping name is too long to fit in the space provided, the lettering
may be reduced to the maximum size possible to fit. For example: "CARBON DIOXIDE, SOLID".
Insert "AS COOLANT" or "AS CONDITIONER" as appropriate. The lettering shall be in
capitals, all be on one line and be at least 25 mm high.
The mark shall be a rectangle. The minimum dimensions shall be 150 mm wide x 250 mm high. The
word "WARNING" shall be in red or white and be at least 25 mm high. Where dimensions are not
specified, all features shall be in approximate proportion to those shown.
The word "WARNING" and the words "AS COOLANT" or "AS CONDITIONER", as appropriate,
shall be 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 otherwise.
Documents (such as a bill of lading, cargo manifest or CMR/CIM consignment note) associated with
the carriage of vehicles or containers containing or having contained substances used for cooling
or conditioning purposes and have not been completely ventilated before carriage shall include the
(a) The UN number preceded by the letters "UN"; and
(b) The name indicated in Column (2) of Table A of Chapter 3.2 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, if
any, concluded between the countries concerned in the transport operation provide otherwise.
For example: UN 1845, CARBON DIOXIDE, SOLID, AS COOLANT.
The transport document may be in any form, provided it contains the information required in
220.127.116.11.1. This information shall be easy to identify, legible and durable.
Requirements for the construction and testing of packagings, intermediate bulk containers (IBCs), large packagings, tanks and bulk containers
REQUIREMENTS FOR THE CONSTRUCTION AND TESTING OF PACKAGINGS
The requirements of this Chapter do not apply to:
(a) Packages containing radioactive material of Class 7, unless otherwise provided (see 4.1.9);
(b) Packages containing infectious substances of Class 6.2, unless otherwise provided
(see Chapter 6.3, Note and packing instruction P621 of 18.104.22.168);
(c) Pressure receptacles containing gases of Class 2;
(d) Packages whose net mass exceeds 400 kg;
(e) Packagings for liquids, other than combination packagings, with a capacity exceeding
The requirements for packagings in 6.1.4 are based on packagings currently used. In order to take into
account progress in science and technology, there is no objection to the use of packagings having
specifications different from those in 6.1.4, provided that they are equally effective, acceptable to the
competent authority and able successfully to withstand the tests described in 22.214.171.124 and 6.1.5.
Methods of testing other than those described in this Chapter are acceptable, provided they are
equivalent, and are recognized by the competent authority.
Every packaging intended to contain liquids shall successfully undergo a suitable leakproofness test.
This test is part of a quality assurance programme as stipulated in 126.96.36.199 which shows the capability
of meeting the appropriate test level indicated in 188.8.131.52.3:
(a) Before it is first used for carriage;
(b) After remanufacturing or reconditioning, before it is re-used for carriage;
For this test, packagings need not have their own closures fitted.
The inner receptacle of composite packagings may be tested without the outer packaging provided the
test results are not affected.
This test is not necessary for:
- Inner packagings of combination packagings;
- Inner receptacles of composite packagings (glass, porcelain or stoneware), marked with the
symbol "RID/ADR" according to 184.108.40.206 (a) (ii);
- Light gauge metal packagings, marked with the symbol "RID/ADR" according to
220.127.116.11 (a) (ii).
