The procedures leading to the disaster had actually been
However, according to modern sources and contrary to the above-mentioned 1919 tests, the "less than 60% nitrate = safe" criterion is inaccurate; in mixtures containing 50% nitrate, any explosion of the mixture is confined to a small volume around the initiating charge, but increasing the proportion of nitrate to 55–60% greatly increases the explosive properties and creates a mixture whose detonation is sufficiently powerful to initiate detonation in a surrounding mixture of a lower nitrate concentration which would normally be considered minimally explosive. For a real world example of dynamite detonating 500 tons of ammonium nitrate (with no fuel), look up the “Oppau Explosion.” The French Miistry of Environment describes it in a publication that you can find if you google: “FD_14373_oppau_1921_ang.pdf”
It has therefore been proposed that one of the charges had been placed in or near such a pocket, exploding with sufficient violence to set off some of the surrounding lower-nitrate mixture.Two explosions, half a second apart, occurred at 7:32 am on September 21, 1921, at Silo 110 of the plant, forming a The damage to property was valued in 1922 at 321 million Five hundred bodies were recovered within the first 48 hours,(slides for a talk given at UKELG (United Kingdom Explosion Liaison Group), Loughborough University) There is also evidence that the lot in question was not of uniform composition and contained pockets of up to several dozen tonnes of mixture enriched in ammonium nitrate. The objective of the present report is to clarify actualities and to ascertain the chemical-technical

The explosion occurred on September 21, 1921, when a silo that was storing 4,500 tonnes of ammonium sulfate and ammonium nitrate fertilizer mixture exploded at the Oppau plant in Germany.

The blast was felt for miles, damaging the factory […] causes of the tragedy at Oppau, with the highest degree of certainty possible. Changes in humidity, density, particle size in the mixture and homogeneity of crystal structure also affect the explosive properties.A few months before the incident, the manufacturing process had been changed in such a way as to lower the humidity level of the mixture from 3–4% to 2%, and also to lower the apparent density.
