The risks posed by poor conditions of storage of this common compound, which is used extensively in the Fertilisers and Explosives industries, have been well documented but awareness of the dangers of fire during transportation by sea is less well known. The objective of this guide, entitled ‘Ammonium Nitrate Fire Risk on Board Ships’ is to outline best practice with respect to the management of risk on vessels chartered to ship the compound through ports around the world.
Ammonium Nitrate (NH₄NO₃), a white to grey odourless chemical has a melting point of 169 degrees C and decomposes at 210 degrees C. While it does not burn by itself, significantly it will accelerate burning of combustible material, producing toxic oxides of nitrogen and ammonia, which will support combustion, even in the absence of oxygen.
