Investigate uncertainty quantification in the health consequences of the BLEVE in Feyzin disaster

On January 4th 1966, there has a severe blast occurred at the Feyzin refinery in France, killing 18 people, injuring 84, 49 of whom were hospitalized. The accident also resulted extensive damage both inside and outside of the site. This tragedy happened when an operator was draining water from 1200 m pressurized propane sphere lead to LPG spill. The resultant cloud of propane vapour spread 150 m and suddenly it has been ignited by a car at an adjoining road. The storage sphere T61443 had be engulfed in flame due the pool of propane in the bund. The vessel become overheated due to the exposed in fire and fails catastrophically. This result to BLEVE (Boiling Liquid Expanding Vapour Explosion) and lead to the sphere ruptured. The BLEVE producing large fireball which killed and injured fireman and workers. In the era of 60’s BLEVE was poorly understood, thus pressurized tanks were not protected against this phenomenon. The objective of this paper is to present a methodology for assessing the uncertainties quantification in the health consequence of the BLEVE in the Feyzin disaster. The consequences are considered conditional on the BLEVE when occurring. There has two consequence that considered, first is thermal radiation towards structure and human. Second is blast wave effect towards structure and human. In this research we will see all those uncertainty will effect in the health consequence of the BLEVE in Feyzin disaster.
