Process Hazards Analysis (PHA)

Safety Integrity Level Tool (SIL) - SIL Verification Software

Understanding PHA


Process hazards analysis (PHA) is a critical component within the safety lifecycle and most crucially takes place in the design or initial plan of a facility. These studies will identify and discuss risks found within the study and determine whether sufficient safeguards are in place.


Hazard and Operability Studies (HAZOP)

One of the most popular and widely used methods of process hazards analysis is Hazard and Operability Studies, otherwise known as HAZOP. The systematic and rigorous procedure used in the examination of the P&IDs is utilised in breaking down the potential hazards that may arise from any deviations in process operations and parameters.

With extensive experience in HAZOP, xSeriCon is your ideal guide to smoothly navigate through a resource heavy workshop, saving time and delivering work of the utmost quality.

Hazard Identification (HAZID)

Hazard Identification, HAZID, is an effective tool in systematically identifying potential hazards associated with operations, facility, and occupation by personnel at an early stage in the design process. This allows the project team to focus its safety spend on the most sensitive issues of concern.

At xSeriCon with our experience in HAZID we are well-suited to guiding one through the process of HAZID quickly and effectively.

Electrical HAZOP

Similar in operation to a HAZOP study, Electrical HAZOP scrutinises the on-site power distribution for any potential deviations that may arise in the electrical supply. Potential impacts on the process are assessed and existing safeguards evaluated.

xSeriCon's prior experience of leading Electrical HAZOP makes us well placed to guide your team through this specialised and important PHA study.

Checklist

A systematic study focusing on a specific aspect of process safety such as human factors and facility siting. A workshop team assesses an extensive list of items of potential concern, and gathers evidence that each item has been sufficiently addressed.

Drawing on our experience, xSeriCon can provide comprehensive checklists and guide the team to efficient completion of the PHA task.

What-if

A more flexible method of Process Hazards Analysis that is excellent at identifying non-typical potential hazardous events. As the name suggests the procedure involves guided brainstorming through various scenarios by asking questions beginning with “What-if?”. This approach is well suited to Management Of Change (MOC) studies.

xSeriCon’s industry experience in this area allows us to conduct the team through this form of PHA to deliver quality results.
