A person must not offer for transport, handle or transport these dangerous goods in a large means of containment if they are in direct contact with the large means of containment.
If these dangerous goods are stabilized by temperature control, they must be offered for transport, handled or transported in accordance with section 7.1.5 of the UN Recommendations.
If chemical stabilization is employed, the person offering the means of containment for transport must ensure that the level of stabilization will prevent a dangerous polymerization of the dangerous goods at a bulk mean temperature of 50 °C in the case of a small means of containment or an intermediate bulk container (IBC) or, in the case of a large means of containment that is not an IBC, at a bulk mean temperature of 45 °C.
If chemical stabilization may become ineffective at lower temperatures within the anticipated duration of transport, temperature control is required. In determining whether chemical stabilization may become ineffective at lower temperatures, the person offering the means of containment for transport must take at least the following the factors into consideration:
the capacity and geometry of the means of containment and the effect of any insulation;
the temperature of the dangerous goods when offered for transport;
the duration of the transport and the seasonal ambient temperature conditions typically encountered during transport; and
the effectiveness and other physical or chemical properties of the stabilizer employed.
Dangerous goods that are included in Class 6.1 due to inhalation toxicity in accordance with paragraph 2.28(c) of Part 2 (Classification) must, as applicable, be offered for transport, handled or transported under UN3381, UN3382, UN3383, UN3384, UN3385, UN3386, UN3387, UN3388, UN3389, UN3390, UN3488, UN3489, UN3490 or UN3491.
