Major accidents in process industries and an analysis of causes and consequences

This paper briefly recapitulates some of the major accidents in chemical process industries which occurred during 1926-1997. These case studies have been analysed with a view to understand the damage potential of various types of accidents, and the common causes or errors which have led to disasters. An analysis of different types of accidental events such as fire, explosion and toxic release has also been done to assess the damage potential of such events. It is revealed that vapour cloud explosion (VCE) poses the greatest risk of damage. The study highlights the need for risk assessment in chemical process industries. (C) 1999 Elsevier Science Ltd.
