off spec ammonium nitrate


Explanation:
Declasate in sensul ca au fost etichitate gresit si dintr-un ingrasamant cu grad mare de risc a fost transformat intr-un compus care nu prezinta risc de explozie.

http://en.wikipedia.org/wiki/AZF_(factory)

Specifically it is believed by mandated official experts that "a mislabeled 500kg bin of sodium dichloroisocyanurate mistakenly thought to be ammonium nitrate was dumped in the off spec ammonium nitrate warehouse. Here under sufficiently hot and humid conditions it could have reacted with the ammonium nitrate to form nitrogen trichloride which is an exceedingly unstable compound. The decomposition of the nitrogen trichloride could have provided the heat and pressure required to detonate the ammonium nitrate which when used as an industrial explosive typically requires detonators."

http://fr.wikipedia.org/wiki/Usine_AZF_de_Toulouse

L'usine AZF de Toulouse était une usine chimique (AZote Fertilisants) certifiée ISO 14001 et 9002, et classée Seveso, située à Toulouse, en Haute-Garonne. Un de ses hangars, contenant des nitrates déclassés, a explosé le 21 septembre 2001 à 10h17. Elle appartenait à la société Grande Paroisse, filiale d'Atofina. Depuis la fusion en avril 2000 de Total et d'Elf-Aquitaine, Atofina regroupait toutes les activités chimiques du groupe: ARKEMA, GPN, SOFERTI, etc.
