Hiring the right independent person for your HAZOP study is crucial. Process Hazard Analysis (PHA) is required for all industrial-scale plants that store or process flammable, toxic or environmentally hazardous materials. HAZOP is a common method used to check for hazards and operability issues for new or changed designs using a multi-discipline team.
Frequently Asked Questions about HAZOP Study
Process hazards analysis (PHA) is a general term used in the process industry sector for any kind of study that identifies hazards and potential sources of harm to people, environment and assets. A PHA can be done in many different ways.
HAZOP is short for a Hazard and Operability Study. This is a systematic technique used to identify hazards, consequences and safeguards for industrial processes.
The timing of a HAZOP can vary, but it is often best approached when there is sufficient design information; when piping and instrumentation diagrams are available with a meaningful level of detail.
- The duty holder should get someone experienced to lead the HAZOP activity and record team findings.
- Plant operators and maintenance personnel.
- Process experts.
- Electrical, control and instrumentation.
- Process safety / HSE representative.
Layer of Protection Analysis (LOPA) can be combined with a HAZOP study provided this is decided in advance. LOPA takes selected HAZOP scenarios and determines the effectiveness of safeguards as truly independent protection layers (IPL).
In-Person or Remote HAZOP study
eFunctionalSafety has completed many HAZOP studies followed by Layer Of Protection Analysis (LOPA).
