e-LOPA 104-2: Workshop for Layer of Protection Analysis (LOPA)

COURSE DESCRIPTION                                                                                 DURATION: 1 Day, 9AM-4PM

In this course, the participant will work on multiple Process Hazard Analysis (PHA) worksheets and apply Layer of Protection Analysis (LOPA) concepts presented in the Introduction to LOPA course.  Participants are encouraged to send their own PHA worksheets ahead of time so that a LOPA worksheet can be developed for an example that they are familiar with.  This course will be completely hands-on except a brief reminder of the LOPA methodology as the workshop progresses.  Participants without any prior experience with LOPA should first attend the Introduction to LOPA e-Training course.
