Don’t Let Your Safe Operating Limits Leave You S-O-L (Out of Luck)

Recording Date: May 2019

Collection of process safety leading and lagging indicators is an important tool for driving improved safety. Tier 3 leading indicators (challenges to safety systems) indicate failures of process safety management systems and highlight areas that should be improved to prevent a more serious event. Safe Operating Limit (SOL) exceedances are a commonly used Tier 3 leading indicator (per API 754). Despite the broad applicability across industry, the determination and application of SOLs often varies from company to company.

This webinar discusses current industry practices around the determination and application of safe operating limits as established by a recent benchmark survey of over 150 safety practitioners from around the world. Areas explored in the survey of SOLs include; methodology for calculating, how / where information is stored, how / when established values are reviewed and audited, usage as a Process Safety Management Leading indicator, integration with operations (training, documentation), identification and tracking of when exceedances have occurred, and actions taken on exceedance. Key results and conclusions will be presented as well as recommendations on where industry should focus on improvement.
