Just three years later two men were injured when another mill exploded. One man had his clothing burned, the other received a severe back injury when he was hit by flying timber. On 15 April 1847, the military were called in to help contain a fire at the cooperage in the mill complex. Their efforts to prevent the fire spreading to the neighbouring powder store were successful, but the cooperage itself was reduced to ashes. Again, in June 1858, an explosion demolished a small mill in Ballincollig, but no injuries were reported.
