Runaway reactions part 2 Causes of accidents in selected CSB case histories - issue 256

Issue Number: 256


Part 1 briefly discussed the basic thermochemistry of reactive chemicals, the statistics of accidents involving runaway reactions, and general control measures to minimise risk and mitigate the consequences. The present paper highlights the main causes of major accidents from runaway reactions with illustrative case histories to link theory and practice. It also discusses lessons learned from these accidents, which are very similar in the cases studied. The main causes are management deficiencies, inadequate understanding of the process chemistry and thermochemistry, inadequate design for heat removal, inadequate control and safety systems, inadequate operational procedures, including training and human factors.
