The IMO has developed a circular (CCC.1/Circ.2/Rev.1) on the carriage of Bauxit which may liquefy. The circular concerns the risk that Bauxit may assume liquid form if carried in bulk. This circular will be incorporated into the IMSBC Code at the next revision.
Furthermore, the IMO has developed a circular (CCC.1/Circ.4) on the carriage of Ammonium Nitrate Based Fertilizer in bulk. Though it is possible to declare Ammonium Nitrate Based Fertilizer as non-hazardous, it can - if carried in bulk and under special circumstances where it undergoes a mechanical or chemical heat reaction - release hazardous gases.
The two circulars:
- CCC.1/Circ.2/Rev.1, "Carriage of Bauxit which may liquefy"
- CCC.1/Circ.4, "Carriage of Ammonium Nitrate Based Fertilizer (non-hazardous)"
are available from the IMO website.
