In a toy factory, a series of violent explosions, accompanied by a flash, occurred subsequent to a malfunction of the machine used to package detonators in retractable plastic film. Four employees were killed by the shockwave and flying debris, while another 25 were injured. Two women had to be hospitalised due to their wounds and burns (one had burns covering 30% to 50% of her body). The automatic extinction system (sprinklers) combined with fire-fighter intervention brought the incident under control. The factory’s windows were shattered and debris was ejected into the street.
