2015 11 Baboo NFL Safe storage of AN Based Fertilizers

The paper is intended for the use of manufacturers and suppliers. It sets out recommendations for the handling and storage of straight ammonium nitrate fertilizers and compound fertilizers containing ammonium nitrate hereinafter called Ammonium Nitrate based Fertilizers. The recommendations are based on the specific properties of the fertilizers. The paper provides advice on conditions in which ammonium nitrate based fertilizers can be handled and stored safely in both bulk and packaged form. It does not recommend one form of storage in preference to the other. The issuing fertilizer organisations believe that if users of this paper carefully follow these recommendations the potential hazards of these fertilizers during storage and handling are minimised. Appropriate precautions should be taken to protect the product from moisture pick up, for example by air conditioning or covering with plastic. Wood or other readily combustible materials should not be used in the construction of new bays or bins. Where existing wood structures are used the exposed parts should be protected, for example by covering them permanently with tough resilient plastic sheeting. Silos must be provided with a venting device in order to prevent a vacuum being created during tapping operations. Silos should be constructed of plastic or steel such that moisture absorption and product contamination are avoided during storage.
