Help identify causes of process industry accidents

摘要

Industrial accidents due to material failure,human error or external perturbation can cause great personal injury,properly damage and financial loss.Therefore,risk management has become much more important to the process industry to meet process safety objectives.Fault tree analysis(FTA)has been applied in the process industry to identify probable causes of accidents and to estimate the probability of future accidents.It can also be adapted in the quantitative risk analysis(QRA)program.However,manual FTA construction is difficult and time-consuming.Many FTA software programs are available commercially but these are very expensive and many companies need to rely on consultants for risk assessment.The following FTA tool was developed using Microsoft Excel and implemented for use in process safety design.
