Chapter 1the SSD of NPK does not lead to detonation. SSD might lead to the release of large amounts oftoxic gases and vapour (such as NO x up to 300 times the volume of the solid fertiliser). Thiscould theoretically lead to a physical explosion when the gases cannot escape from a closedobject.After solidification of the fresh fertiliser, heat development in some cases is still rather high. Afew days after solidification, some of the fertilisers (e.g. SSP and TSP) are still curing. Some ofthe processes taking place during curing are exothermic (e.g. neutralisation). Generally, thetemperature rises less than 10 ºC [154, TWG on LVIC-AAF, 2006].See Section 9.2.2 about the safety issues of AN production.Deposits of AN in HNO 3 plantsFor safety concerns related to deposits of AN in HNO 3 plants, see Sections 3.4.1, 3.4.10, 3.4.11and 3.5.6 Large Volume Inorganic Chemicals – Ammonia, Acids and Fertilisers
