At 6 p.m. , an explosion occurred in an ammunition neutralizing plant, causing 1 death and 1 injury among personnel and damage to the building and to equipment (pressure wave caused by the detonation of 1 kg of PETN and 0.4 kg mercury fulminate). The technicians were running a pilot-scale testing of a process for ammunition neutralization and wet chemical destruction of priming charges. According to press reports, the 58-year-old deceased worker was dismantling a detonator after a chemical treatment (supposedly to have rendered it harmless).
