IBCs shall be provided with a device to allow venting during carriage. The inlet to the pressurerelief device shall be sited in the vapour space of the IBC under maximum filling conditions during carriage. 2. To prevent explosive rupture of metal IBCs or composite IBCs with complete metal casing, the emergencyrelief devices shall be designed to vent all the decomposition products and vapours evolved during selfaccelerating decomposition or during a period of not less than one hour of fireengulfment as calculated by the formula in 4.2.1.13.8. The control and emergency temperatures specified in this packing instruction are based on a noninsulated IBC. When consigning an organic peroxide in an IBC in accordance with this instruction, it is the responsibility of the consignor to ensure that: (a) The pressure and emergency relief devices installed on the IBC are designed to take appropriate account of the selfaccelerating decomposition of the organic peroxide and of fireengulfment; and (b) When applicable, the control and emergency temperatures indicated are appropriate, taking into account the design (e.g. insulation) of the IBC to be used.
