Around 9 pm, an explosion involving 29 kg of explosives and 1,720 kg of fireworks stars struck in the storage area of a pyrotechnic facility. The storage depot, built with 40-cm thick reinforced concrete walls covered by earth, was entirely blown apart. Damage both inside and outside the plant were estimated respectively at 2 million and 770,000. The explosion caused no casualties; the cause remained unknown. Subsequent to this accident, it was decided to limit the quantities of products stored in the depots to 2,000 kg as well as to isolate the units with sand walls.
