General tab
| Field | Description |
|---|---|
| Study title | Full label (e.g.: Risk analysis — Ammonia storage unit) |
| Studied system | Name of the site, facility or system |
| Unit / Subsystem | Subset if the study is partial |
| Organization / Engineering firm | Company or department responsible for the study |
| Study manager | Name of the project lead |
| Facility manager | Operator or owner of the facility |
| Document reference | Report number (e.g.: RI-2026-001) |
| Version | Increment at each revision (e.g.: 1.0, 1.1, 2.0) |
| Start date / Planned end date | Study planning |
| General description | Brief description of the process or facility |
| General notes | Free remarks about the study |
Methods tab
Hazard study mode (toggle) — enables the PHA-EDD, the PIGC metrics (SEVESO/ICPE) and forces the advanced Bow Tie. Enable it for any SEVESO or ICPE study.
PIGC metrics (sub-option) — enables the regulatory Probability/Intensity/Severity/Kinetics grids. These grids are fixed (compliant with the SEVESO decree) and are not editable.
Analysis methods — check the methods you will use. Only the corresponding pages appear in the side menu:
- PHA — Physical risks
- PHA — Hazard study (requires Hazard study mode)
- FMEA
- HAZOP
- LOPA
Bow Tie type:
- None — no Bow Tie page
- Simple — qualitative cause/barrier/consequence representation
- Advanced — probabilistic quantification, AND/OR gates, MOCUS calculation
Scope & Objectives tab
| Field | Description |
|---|---|
| Objectives | Purpose of the study (e.g.: Identify major SEVESO scenarios) |
| Functional scope | Functions and processes covered |
| Geographical scope | Physical areas included (buildings, units, battery limits) |
| Exclusions | Elements explicitly out of scope — to document for regulatory justification |
| Applicable regulations | Reference texts (SEVESO III, ATEX, prefectural orders…) |
| Assumptions | Conditions assumed true throughout the study |
Team tab
List the study participants:
- First / Last name
- Role — process engineer, HSE, maintenance manager, external expert…
- Role in the study — facilitator, secretary, expert, approver
Sessions tab
Record each work session:
- Date and duration
- Participants present
- Agenda
- Minutes / decisions made
Documents tab
List the input documents used: P&ID, PFD, MSDS, previous studies, site plans…
Revalidation tab
Plan the review of the study:
- Revalidation frequency (e.g.: every 5 years)
- Trigger criteria (facility change, incident, regulatory change…)
- Person responsible for revalidation
- History of past revalidations
