484 - 08/06 - Carriage of Dangerous Goods - IMDG Code Amendment - Worldwide
· There are seven new UN Numbers, going up to 3474, and 18 current Numbers are deleted.
· There are numerous detailed changes to the Dangerous Goods List, the special provisions, packing instructions and provisions, and to most of the chapters of the code.
· The details on the dangerous goods transport document must be given with the UN Number first. The alternate format with the name first is no longer allowed. See 188.8.131.52.
· UN 1950 aerosols are no longer 'class 2' when in limited quantities. They are class 2.1 or 2.2 as appropriate. There is a new classification of 'waste aerosols', which applies to short voyages only, and must be on deck only and not in a closed CTU. See SPs 327 and 959. More detailed rules are given in 6.2.4 for the testing of aerosols.
· With flammable liquids, the upper limit on flashpoint for them to be classified as hazardous is reduced from 61 to 60°C c.c.
· For fireworks there is a new several-page section 184.108.40.206 describing how they are allocated to the divisions and compatibility groups of class 1.
· There is a new yellow and red label for class 5.2, organic peroxides. The present all-yellow label can be used until 1 January 2011.
· Fumigated units UN 3359 can no longer have their labels removed after they have been ventilated. Instead, the date of ventilation is written on the label, which stays on until the unit has been unloaded.
· Segregation is not required between defined groups of substances which are chemically similar but are allocated to different, conflicting, classes. One table lists six UN Numbers of peroxides, and another lists three compounds of silicon and chlorine. See 220.127.116.11.1.
· Between a class 8 acid and a class 8 alkali, the usual requirements of 'separated from' alkalis and 'separated from' acids can be ignored provided both substances are of packing groups II or III, in packages not exceeding 30 kg or 30 litres, and provided a test report says the substances do not react dangerously.
