On 28th August 1992, in a food factory, a liquefied nitrogen storage tank catastrophically failed, causing the destruction of the upper half of the factory as well as damaging other factories and structures partially, including the outer walls, window glass, and shutters of 25 buildings, 39 parked vehicles consisting of busses, trucks and cars, and electric poles in a circle with radius of 1,304’ (400 meter). Fragments of the vessel were projected up to 1,150′ (350 meters), the largest of which, a section of the outer shell head was 5’ (1.5 meters) wide and 8mm thick. The tank was a vertical type, double shell, vacuum insulating vessel (model CE-7500). The piece of the vessel that flew the furthest was the top dish plate of the outer vessel, 1.5m in diameter and 8mm in thickness that reached a distance of 1,148′ (350m). The insulator composed of pearlite scattered over a circular area with a radius of 328′ (100m). The direct cost of the damage was estimated to be about 440 million yen ($443K).
