Competency can help organizations better manage chemical process risks
A new topic has been added to the workshop for the National Chemical Safety Symposium on October 11 in Houston, TX. In addition to talking about Operational Excellence in environmental, health and safety, the workshop also includes discussions on the Layer of Protection Analysis (LOPA), facilitated by Arthur M. Dowell III, PE Chemical Process Safety Consultant.
How safe is safe enough? Additional safeguards, or independent protection layers, can always be added, but how can your team decide and defend how many and what type of safeguards or barriers are enough to prevent or mitigate a chemical process event?
LOPA is a tool that focuses risk reduction efforts toward the impact events with the highest risks. It provides a rational basis to allocate risk reduction resources efficiently for a specific scenario.
Scenarios are identified typically using a scenario-based process hazard analysis (PHA) evaluation procedure. For selected higher risk scenarios, LOPA is an analysis tool/approach that can be used to analyze one incident scenario (cause-consequence pair) at a time, using values for the initiating event frequency, independent protection layer failure probabilities, and consequence severity, in order to compare a scenario risk estimate to risk criteria for determining where additional risk reduction or more detailed analysis is needed.
A case study of a scenario will be presented to guide attendees to illustrate how a LOPA is done to help a team with risk-based decisions for a process. To confirm your attendance for this educational event, register today and take advantage of our early bird rate!
