In a PVC plant, an MVC leak ignited causing a (UVCE-type) explosion. The plant comprised 2 production buildings, one housing a boiler room and maintenance workshop, the other the laboratory, offices and warehouse, along with a series of MVC tanks (four with 180-m³ capacity) and a warehouse annex. The buildings were all equipped with sprinklers. Building V-1 had 20 7.5-m3 capacity polymerisation reactors, each fitted with a window. During this Sunday's daytime shift, the opaque window glass on Reactor 4 was replaced. The reactor was reloaded wit [...]
At 10:39 pm, the landslide of a portion of Mount Toc sent 260 million m3 of earth and rock hurtling at more than 90 km/h into the full reservoir adjoining the Vajont Dam. The falling rock nearly instantaneously filled the storage reservoir. Two waves, containing 25 million m3 of water each, unfurled both downstream and upstream of the reservoir. The water rose above the dam crest, forming a wave higher than 150 metres that rushed into the gorge in the direction of downstream, town of Longarone.
The thrust of this water mass into the very narrow [...]
At a chemical plant, an explosion destroyed a building storing 4,500 tonnes of a 50-50 composition of ammonium sulphate-nitrate, forming a crater 90 m wide, 125 m long and 20 m deep. Shortly thereafter, a series of fires broke out on the facilities, caused by a domino effect, amidst other explosions of lesser intensity. Heard more than 275 km away, the detonation created panic among the local population. A dark green cloud blanketed the sky over the region, and the telegraph and telecommunications infrastructure was destroyed. The extent of dam [...]
