⚙ Industrial Risk Module

1Module overview

The module Industrial Risk in Polyodos covers the entire industrial-risk analysis lifecycle, from context description to Word-report export.

Typical workflow

2Create an Industrial Risk project

From the home page, click New project. Enter a name and select the project type.

3Assessment context

The Context is the required starting point. It defines study metadata and methods to use.

Information to enter

Select methods

Select only the methods you want to use. Only corresponding pages will appear in the navigation menu.

4Model the facility

Modelling structures the facility into a three-level hierarchy: systems → components → functions. This structure is reused across analysis pages to link every scenario to specific equipment.

Hierarchy

Add elements

1. Click + Add a system —enter a name and short description
2. Select the created system, then click + Composant to attach equipment
3. For each component, add one or more functions
4. Repeat for each subsystem in your facility

5PHA—Preliminary Hazard Analysis

Polyodos provides two PHA variants based on your facility's regulatory context:

Physical-Risk PHA columns

Enter a scenario

1. Click + Add a row at the bottom of the table
2. Select the system andequipment involved
3. Enter the hazard, hazardous event, causes, and consequences
4. Assign inherent S and L ratings—the criticality cell is coloured automatically
5. Enter preventive measures and residual ratings

6FMEA—Failure Modes, Effects and Criticality Analysis

FMEA identifies failure modes for each component, evaluates criticality through theRPN (Risk Priority Number = Severity × Occurrence × Detectability), and defines corrective actions.

Colonnes AMDEC

Filter and sort

Use the column-header filters to quickly isolate critical failure modes or focus on a particular system. Sorting by decreasing RPN identifies action priorities in one click.

7HAZOP — Hazard and Operability Study

HAZOP analyzes process-parameter deviations from nominal conditions by combining guide words (No, More, Less, Reverse…) with parameters (flow, pressure, temperature, level…).

Colonnes HAZOP

8LOPA — Layer Of Protection Analysis

LOPA quantifies the frequency of hazardous events by accounting for independent protection layers (IPLs) and checks whether the residual risk is tolerable.

Colonnes LOPA

Add IPLs

1. In a LOPA row, click + IPL to add a protection layer
2. Select the type IPL type (BPCS, SIS, relief valve, dike, procedure…)
3. Enter the PFD (e.g. 0.1 for a SIL 1 SIS)
4. The residual frequency is recalculated automatically after every change

9Bow-Tie

The bow-tie graphically represents a top event, with causes on the left and consequences on the right, showing prevention and protection barriers.

Two diagram modes

Create a diagram

1. In the side panel, click + Simple or + Advanced as required
2. Name the diagram and define thetop event in the center
3. Add the causes on the left (right-click the top-event node → Add a cause)
4. Add the consequences on the right
5. Place barriers on the links (click a link → Add a barrier)

10Metrics and risk matrix

The Metrics defines the rating scales (Severity, Likelihood) and criticality matrix used throughout the project analyses.

Configurable elements

11Generate the report

Polyodos provides two complementary reporting pages:

Generate the Word report

1. Open the Industrial Risk report from the navigation menu
2. Check the sections to include (context, tables, matrix…)
3. Click ⬇ Exporter Word (.docx) —the file is generated directly in your browser
4. The report is automatically named using the study title and date

Custom report generator

The generator creates tailored reports for each method. Each section contains Markdown text with variables automatically replaced by project data:
