VAIL-PHA Software Solutions | PHA HAZOP: Process Hazard Analysis

Process Hazard Analysis (PHA) is defined as the analysis of potential causes and consequences of fires, explosions, releases of toxic or flammable chemicals and major spills of hazardous chemicals. It focuses on instrumentation, equipment, utilities, human interference, and external elements that can possibly impact the process.

It is a key element of every Process Safety Management (PSM) program. The main objective of such analysis is to identify hazards within the subject process by systematically reviewing the process and subsequently eliminating or controlling conditions that could lead to hazardous events.

VAIL- PHA SIL software is Velosi’s proprietary software and is built to execute all stages of SIL Classification, SIL Verification and preparation of Safety Requirement Specifications (SRS). The software also supports testing interval and Spurious Trip Rate (STR) calculations of SIFs.

The software product is developed in compliance with ANSI/ISA TR84.00.02, IEC – 615011 and IEC 61508. Various methodologies are available for assessment of target SILs.
