Layer of Protection Analysis with LOPAx™

Recording Date: April 2015

There is no doubt that Layer of Protection Analysis (LOPA) has been widely accepted as the method to use for detailed accident likelihood evaluations. exida has released a new tool, LOPAx™, that allows advanced likelihood evaluations. More importantly the tool is tightly integrated with the exida Process Hazard Analysis (PHAx™) tool. Both PHAx and LOPAx are modules within the exSILentia® safety lifecycle software. The integration of safety lifecycle phases is the key to consistency and efficiency. This webinar will discuss the principles of LOPA and show a live demo of the exida LOPAx software and its integration with the PHAx software.
