Chemical safety during plant shut-downs

Research output: Contribution to journalArticleProfessional


Major chemical installations are designed to run for months without any stoppages. Still, well planned maintenance shut-downs are needed in order to avoid unwanted disturbances at the plants. Until now, research on shutdowns has mainly been focusing on risks caused by the contractors, while the aim of a study led by VTT was to investigate, if the safety management systems of the production companies were such that they ensured the safety of the contractor workers during shut-downs. The study was restricted to risks caused by process chemicals. In a vast majority of cases, process chemicals are present at the site also during shut-downs and many times parts of the process plant are still in operation during the shut-down. In order to highlight the issue of hazards caused by process chemicals, the VTT led research project produced material in Finnish, which is available on the Internet at The results of the study may in part or as a whole be taken into use by any organisation without any charge
