EXPLOSIVES HUT just the other side of the Bridge with a green door.  The explosives for the fog signal was stored in this concrete hut with a steel lined door. The fog signal started 3rd May 1909. On May 21st, 1920, Mizen Head was raided by armed men and practically all the explosives were removed. As no protection was offered to the station by the Government, the Board stated that all Explosive Fog Signal Stations around the coast would be closed down. The fog signal was re-established on February 29th, 1924. The Fog Signal was an explosive charge of aluminium tonite which was attached to a harness outside the Fog Signal House which was the house at the very end of the Mizen and detonated two explosions in quick succession at 7 ½ minute intervals throughout fog. The explosive fog signal was withdrawn finally in 1969 with the troubles in the North and more importantly the rise of satellite and racon navigation.
