Process Hazard Analysis
Identify risks, sharpen decisions, and protect your operations with DEKRA-led PHA services
A process hazard analysis (PHA) is more than a regulatory requirement, it’s a vital tool for identifying and mitigating risks that could lead to fires, explosions, toxic releases, or other catastrophic incidents.
At DEKRA, we help organizations across industries conduct comprehensive, efficient PHAs that improve safety, ensure compliance, and strengthen decision-making.
Whether you're conducting a new study, revalidation, or management of change (MOC) assessment, our team brings the expertise, structure, and insight needed to uncover hazards and guide smart, practical risk controls.
