    Grain dust explosions have been recorded as far back as December 1785, when one of the first documented cases occurred at a bakery warehouse in Turin, Italy. Count Morozzo investigated the explosion and found that a portion of bakery flour, which was exceptionally dry, created a dust cloud when it dropped from an upper portion of the warehouse. Heat from a mounted lamp ignited the flour, causing an explosion that propagated in multiple directions and injured two people.

    Over the ensuing three centuries, similar incidents followed.
