Barium Nitrate: IMSBC Schedule and Carriage
IMSBC Code schedule for BARIUM NITRATE UN 1446: Group B, IMDG Class 5.1 oxidiser with a 6.1 subsidiary hazard, toxic by ingestion and dust inhalation.
BARIUM NITRATE UN 1446 is a Group B solid bulk cargo under the IMSBC Code, classified as an IMDG Class 5.1 oxidising substance with a subsidiary hazard of 6.1. The Code describes it as glossy white crystals or powder, soluble in water, and its hazard field reads that the cargo is toxic if swallowed or by dust inhalation and that if involved in a fire the mixture with combustible materials is readily ignited and may burn fiercely.
It shares an element and nothing else with barytes . The distinction that matters is solubility rather than the element: barium sulphate is effectively insoluble and therefore chemically inert, while soluble barium salts such as the nitrate are toxic. A cargo offered only as a barium cargo tells the master nothing useful about which of the three barium entries in the Code applies.
The full article will cover the schedule, the segregation requirements that follow from Class 5.1 , the emergency procedures, and the stowage away from combustible material and foodstuffs.
