Implementing SIS Metrics for Process Safety Events

This paper will overview the key elements of implementing a Process Safety Event Log.   The key elements of implementing this type of system are:

• Identifying equipment performing Safety Integrity Functions (SIF) in the Process Control Layer
• Identifying the equipment in the Enterprise Management System
• Creating the Process Safety Event Log
• Documenting Process Safety Events
• Documenting Process Safety Event Investigation Classification and Details
• Generating Metrics
• Driving action with the information

Each of these elements are essential to an effective SIS Metric Implementation … whether for one or for many metrics.   These elements can be aggregated into the categories:  1) Business justification, 2) System Implementation and 3) Action Execution.   Implementation of SIS Metrics aligns to the CCPS Vision 20/20 (American Institute for Chemical Engineers 2014) initiative by supporting the Industrial Tenant of Disciplined Adherence to Standards and the Societal Themes of Harmonization of Standards and Meticulous Verification.
