SaaS Platform for Industrial Quantitative Risk Analysis

## What is TekRisk PRO?

TekRisk PRO is a web-based quantitative risk analysis (QRA) platform designed for industrial safety engineers, environmental consultants, and decision-makers in the chemical and oil & gas industries.

The platform centralizes consequence modeling, individual and societal risk analysis, and professional report generation in a single tool — eliminating the need for scattered spreadsheets and specialized desktop software.

## Consequence Models

TekRisk PRO includes 6 simulation models covering the main industrial hazard phenomena:

| Model | Phenomenon | Typical Application |
|-------|-----------|---------------------|
| **BLEVE / Fireball** | Fireball from catastrophic vessel rupture | Pressurized LPG tanks, liquefied gases |
| **Pool Fire** | Flammable liquid pool fire | Hydrocarbon spills, solvents, fuels |
| **Jet Fire** | Pressurized jet fire | Leaks from pipelines, valves, flanges, and fittings |
| **VCE** | Confined vapor cloud explosion | Flammable clouds in confined or semi-confined areas |
| **Flash Fire** | Flammable cloud ignition without overpressure | Flammable gas dispersion in open field |
| **Toxic Dispersion** | Atmospheric toxic gas dispersion (SLAB model) | Chlorine, ammonia, H₂S, hydrofluoric acid releases |

Each model calculates impact zones at different damage levels, allowing assessment of the reach of an accidental scenario and its effects on people, equipment, and structures.

## Risk Analysis Workflow

Risk analysis in TekRisk PRO follows a structured 7-step workflow:

1. **Create project** — Define geographic location, facility data, and study context
2. **Define risk sources** — Register equipment, pipelines, or process areas and assign chemical substances
3. **Configure weather scenarios** — Set wind conditions, temperature, humidity, and atmospheric stability class
4. **Run consequence models** — Simulate accidental scenarios and obtain impact zones
5. **Define receivers** — Locate populations, buildings, equipment, and infrastructure in the area of influence
6. **Evaluate risk** — Calculate individual risk (IR) by location and societal risk (F-N curve)
7. **Generate reports** — Produce professional PDF documents with complete results

## Interactive Map Visualization

TekRisk PRO integrates interactive maps with multiple geospatial visualization capabilities:

- **Multiple map styles**: satellite, dark, streets, and outdoors
- **Overlaid risk zones**: visualization of impact areas directly on the map
- **Wind rose**: directional petals for flash fire scenarios based on wind direction probability
- **Differentiated markers**: risk sources, receivers, and ignition points with distinctive iconography
- **Measurement tool**: distance measurement directly on the map
- **KML export**: download geospatial data for use in Google Earth and GIS systems

## Risk Criteria & Standards

### Individual Risk

TekRisk PRO allows evaluation of individual risk against internationally recognized acceptability criteria:

| Criterion | Country / Organization |
|----------|----------------------|
| **HSE** | United Kingdom — Health and Safety Executive |
| **ASEA** | Mexico — Agency for Safety, Energy, and Environment |
| **RIVM** | Netherlands — National Institute for Public Health |
| **HIPAP No. 4** | Australia — Hazardous Industry Planning Advisory Paper |
| **Hong Kong** | Hong Kong — Risk Guidelines |
| **EPA** | United States — Environmental Protection Agency |

### Societal Risk

- F-N curve with acceptability zones: **acceptable**, **ALARP** (as low as reasonably practicable), and **unacceptable**

- Graphical visualization of the frequency-number of fatalities relationship

### Probit Effects

- Thermal radiation (first, second, and third degree burns)
- Overpressure (blast wave damage)
- Toxicity (concentration-time exposure)
- Domino effect (damage to adjacent equipment)

## Professional Reports

TekRisk PRO generates comprehensive PDF reports ready for submission to regulatory authorities and clients:

- **Scenario data**: chemical substance, physicochemical properties, environmental conditions
- **Risk zones**: tables and diagrams with impact distances by damage level
- **Model-specific diagrams**: visual representation for each phenomenon type (fireball, jet fire, pool fire, VCE, flash fire)
- **Fatality tables**: casualty estimation by zone and effect level
- **Individual Risk Report**: individual risk contours and average individual risk results
- **Societal Risk Report**: F-N curve with acceptability zones

## Chemical Substance Database

TekRisk PRO includes an integrated database with over 1,300 chemical substances and the properties needed for consequence modeling:

- **General properties**: molecular weight, boiling point, melting point, flash point, autoignition temperature, density
- **Thermal properties**: heat of combustion, heat of vaporization, heat capacity (gas and liquid)
- **Flammability limits**: LFL (lower flammable limit) and UFL (upper flammable limit)
- **Toxicity indices**: IDLH, ERPG-1, ERPG-2, ERPG-3
- **Hydrocarbon mixtures**: support for custom blends (Standard plan and above)
- **Search**: by substance name or CAS number
