Article
Accés obertJet fires are often considered to be a minor fire accident, as compared to pool or tank fires. However, if there is flames impingement on an equipment very high heat flux densities will be reached, which can originate its ... -
Domino effect in chemical accidents: main features and accident sequences
Casal Fàbrega, Joaquim; Darbra Roman, Rosa Maria (Elsevier, 2010-09-06)
Article
Accés restringit per política de l'editorialThe main features of domino accidents in process/storage plants and in the transportation of hazardous materials were studied through an analysis of 225 accidents involving this effect. Data on these accidents, which ... -
