Throughout the summer, several accidents continued to affect the production of the factory. The nasty fate of dynamite production in Ascona culminated with a major explosion on December 13, 1874, when houses were shaken as if by a big earthquake, with cracking in walls and ceilings. A subsequent great fire took place in which 4000 kilograms of nitroglycerin were inflamed with a terrible echo of successive explosions, heard in a radius of six km. Worker Federico Cattomio, aged of 23, born in Paris, France, was actively engaged in the prevention of the inflammation and reported killed.
