“…Further light on BLEVE mechanism, which provides useful insights for BLEVE prevention, has been shed by the recent fire tests, on PLG-containing vessels, by Birk et al [23], Birk and VanderSteen [64], Roberts et al [29], Stawczyk [58] and VanderSteen and Birk [61]. The tests of Birk and VanderSteen, which augment the ones done earlier by Birk and Cunningham [2], and Kielec and Birk [60], indicate that for a BLEVE to occur, the tank must first be weakened to the point where an initial pin hole rupture is formed.…”
