Abstract
During risk assessment exercises, it is often identified that current independent layers of protection are insufficient. Process safety managers are left searching for ways to achieve required IPL compliance without extremely costly or invasive solutions in a facility. Looking to borrow best practices from other parts of the globe is a useful resource. One simple practice that has proven to be a very effective tool is a captive key/lock system. This best practice has been recognized in the book by CCPS regarding layers of protection.
With the use of Captive Key Systems, 2 IPL credits can be easily obtained with no changes to current piping or infrastructure. Dangerous process can range from simple PSV isolation systems to more complex procedures like pipeline pigging, chemical regeneration processes or furnace de-coking. Learning from worldwide best practices can add useful tools in the PSM’s playbook. This presentation will explain Data Table 5.35 and the benefits of implementing a Captive Key/Lock System during a LOPA exercise.
