PHA and Risk Assessments
Trinity’s team of experts understand the PHA (Process Hazard Analysis) is vital in assessing risks in industries like chemical, oil, and manufacturing, identifying potential hazards and implementing preventive measures for safety. Accurate application of risk tolerance criteria is critical for our clients to properly steward their resources. We recognize applying the most appropriate risk identification and evaluation techniques is critical to a successful study.
Trinity has facilitated Process Hazard Analyses (PHAs) for many oil and gas processing technologies, as well as many specialized chemical processes unique to specific clients. The quality and comprehensiveness of each risk study drives many other aspects of your overall Process Safety Management (PSM) program – our facilitators perform every study with this in mind.
Over the years, our dedicated PSM/RMP team has completed hundreds of PHAs, Layers of Protection Analysis (LOPA), and other hazard evaluation studies. From nearly every sector, our experts have worked with some of the largest companies in the petrochemical industry.
Additionally, we are well-versed in how to apply PHAs to the life-cycle stage of a plant – including design, startup, projects, initial unit PHAs, unit revalidations, and decommissioning studies.
