About PHA Comp

PHA Comp – The Process Hazard Analysis Compliance Tool is part of the ProSET® software suite for use in PHA studies such as Hazard and Operability studies (HAZOP studies).  Engineering Safety Consultants (ESC) has applied its 100+ combined years of technical safety know-how to develop the ProSET® family of tools.

Conducting hazard and risk assessments is a requirement of Phase 1 of the IEC 61508 and IEC 61511 Functional Safety Lifecycle.

PHA Comp covers all major PHA methods such as HAZOP, Hazard Identification (HAZID) and Control Hazard and Operability (CHAZOP).

Why PHA Comp?

Setup default deviations to your company standards which are configurable to add, removed and/or modify deviations based on a particular PHA study
Setup default risk matrix to your company standard
Conduct both batch and continuous processes studies, not limiting the type of studies you can conduct
Risk Ranking tool allows the likelihood and severity of the hazardous consequence to be set before and after safeguards are applied. This helps to identify where an additional action, such as a Quantitative Risk Assessment (QRA), is required
Review Actions taken in the PHA study through the Actions Manager in one place without having to go through each node
Generate an Actions only report, allowing participants of the PHA study to know instantly what Actions are required and who is responsible for each
Provide an Actions response to track how each action is being resolved
Export of information from PHA Comp to prepopulate information in the SIL Comp® module as part of a SIL Determination or SRS and/or CBA
Maintain a consistent approach by reusing Actions and Safeguards
Available in multiple languages including English, German, Chinese (simplified), Arabic, Spanish and French


Flexibility in modifying PHA Comp to your company standards as well as the different PHA studies that can be conducted
Studies conducted using PHA Comp become quicker, easier and more cost effective leading to a reduction in project man-hours
Ensures consistency in approach and methodology, aiding in improving the quality of studies performed
User friendly and easy to navigate, allowing PHA Comp® to be used by the inexperienced and tech savvy


ProSET® is licensed to an individual machine but can be deactivated to be used on another, great when, for example, one department would carry out a SIL Determination and another department the SIL Verification.
