package may have leaked or been damaged, access to the package shall be restricted and a
qualified person shall, as soon as possible, assess the extent of contamination and the resultant
radiation level of the package. The scope of the assessment shall include the package, the vehicle,
the adjacent loading and unloading areas, and, if necessary, all other material which has been
carried in the vehicle. When necessary, additional steps for the protection of persons property and
the environment, in accordance with provisions established by the competent authority, shall be
taken to overcome and minimize the consequences of such leakage or damage.
(5.2) Packages damaged or leaking radioactive contents in excess of allowable limits for normal
conditions of carriage may be removed to an acceptable interim location under supervision, but

further action.
CV34 Prior to carriage of pressure receptacles it shall be ensured that the pressure has not
risen due to potential hydrogen generation.
CV35 If bags are used as single packagings, they shall be adequately separated to allow for the
dissipation of heat.
CV36 Packages shall preferably be loaded in open or ventilated vehicles or open or ventilated
containers. If this is not feasible and packages are carried in other closed vehicles or
containers, the cargo doors of the vehicles or containers shall be marked with the following in
letters not less than 25 mm high:
"WARNING NO VENTILATION
OPEN WITH CAUTION"
This shall be in a language considered appropriate by the consignor.
For UN Nos. 2211 and 3314 this mark is not required when the vehicle or container is already marked
according to special provision 965 of the IMDG Code3.
CV37 Before loading, these by-products shall be cooled to ambient temperature, unless they have
been calcined to remove moisture. Vehicles and containers containing bulk loads shall be adequately
ventilated and protected against ingress of water throughout the journey. The cargo doors of the
closed vehicles and closed containers shall be marked with the following in letters not less than
25 mm high:
"WARNING
CLOSED MEANS OF CONTAINMENT OPEN WITH CAUTION"
This shall be in a language considered appropriate by the consignor.
3 Warning mark including the words “CAUTION – MAY CONTAIN FLAMMABLE VAPOUR” with lettering not
less than 25 mm high, affixed at each access point in a location where it will be easily seen by persons prior to opening
or entering the vehicle or container.
