Human Error Probability Analysis in Process Safety Management: A Comprehensive White Paper for OSHA PSM Compliance
This white paper explains how Human Error Probability Analysis (HEPA) strengthens OSHA Process Safety Management by quantifying human error risk, detailing proven methods (THERP, HEART, SPAR-H), real-world case studies and practical integration into PHAs, procedures, training, alarms and digital safety systems. It shows how aligning HEPA with regulatory requirements, modern technologies, and performance metrics improves audit readiness, reduces catastrophic risk and embeds human factors as a core pillar of resilient, compliant process safety programs.
