Review: Hydrogen Tank Explosion in Gangneung, South Korea
A devastating hydrogen tank explosion occurred in Gangneung, South Korea on May of 2019. Two men died and several buildings including even for more than 100 meters away, have been seriously damaged. The cause of the explosion has been found that oxygen is permeated into the hydrogen storage tank. It was a P2G testing site and a hydrogen is ...
Modeling the consequences of gas leakage and explosion fire in liquefied petroleum gas storage tank in Istanbul technical university, Maslak ...
In case of LPG leakage from the storage tank, the concentration of LPG was about 2100 ppm which is equal to the lower explosive limit at the distance of 187 m. The consequences of combustion and explosion of LPG gas at a distance of 65 m from the storage tank were the most serious danger that threatens humans.

University of Hawaii lab explosion caused by inappropriate gauge
The 16 March explosion that maimed postdoc Thea Ekins-Coward at the University of Hawaii (UH), Manoa, resulted from her using a pressure gauge "not rated or designed" for use in a "flammable gaseous atmosphere," according to a report issued on Monday by the Honolulu Fire Department. She used a digital gauge "to check the …
Solved When a compressed gas storage tank fails, the | Chegg
When a compressed gas storage tank fails, the resultant explosion occurs so rapidly that the gas cloud can be considered adiabatic and assumed to not mix appreciably with the surrounding atmosphere. Consider the failure of a 2.5 m3 air storage tank initially at 15 bar. a) Calculate the work done on the atmosphere, assuming reversibility.
