The significance of accidental releases has increased during the past few years. The reason for this is that the level of continuous process emission has gone down, partly due to more stringent environmental regulations and partly due to technical improvements. The aim of the study was to minimize accidental releases from a sulphate pulp mill. Some well-known methods of risk analysis were used as a tool. This article presents the application of risk analysis to reduce accidental releases of concentrated malodorous gases from a sulphate pulp mill. This particular objective was chosen not only because of the inconvenience caused by the smell but also the possible health hazards which have been of growing concern recently. In this study, risk analysis has proved to be a recommendable tool in environmental protection of sulphate pulp mills. However, only thorough advance planning before analysis begins can guarantee the most efficient and beneficial results of risk analysis. The aim of the examination and the resources available have an effect on the selection of the method and also on the level of examination.
