Process Hazards Analysis is the first step in the functional safety lifecycle with the objective to identify potential hazards posed by the process and associated equipment. The step is critical, as adequate risk reduction measures cannot be implemented for hazards that are not identified or not identified correctly.

The exSILentia — PHAx tool is based on the Hazard and Operability (HAZOP) methodology, allowing users to identify cause-consequence pairs that lead to hazard scenarios. The software allows users to assign multiple cause-consequence pairs to a single hazard scenario.

The exSILentia — PHAx tool allows the definition of units within a plant and nodes within units. Deviations which are the cornerstone of the HAZOP methodology can be pre-defined for each node type. Subsequently a cause with associated consequence, safeguards, and recommendations can end up defined for each deviation. As part of this, Hazard Scenarios can be documented to facility subsequent phases in the lifecycle including the layer of protection analysis.

exSILentia – PHAx supports compliance with industry regulations (e.g. OSHA PSM, Seveso III Directive, SA OSHA, etc.) and best practices, forming the foundation of a process safety management system.

PHAx is a Process Hazards Analysis (PHA) tool that can be used by engineering personnel in project, process, process safety, and control, as well as plant management, and operations personnel.

PHAx guides users through the PHA process, effectively focusing the user on the task at hand, identifying hazards, hazardous events, and associated sequence of events, allowing the user to easily document the relevant and important facts for process hazards.
