Natural hazards triggering accidents
Flood, earthquake, lightning and extreme heat scenarios are screened against hazardous energy sites to find where one event could disable several barriers together, known as Natech risk.

Process safety at energy facilities
Process safety engineering covers the hazards of energy facilities: refineries, gas terminals, hydrogen plants, battery storage sites and nuclear installations. It explains how layered barriers prevent fires, explosions and toxic or radioactive releases, and how a natural hazard can defeat several barriers at once.

02Application
What process and industrial safety engineering does here.
Process and industrial safety engineering prevents and mitigates fires, explosions and toxic releases in industrial facilities. It addresses hazards that can affect workers, surrounding communities and connected supply chains. In energy, critical infrastructure and climate and hazards, process safety analysis shows how industrial failures affect health, environment and supply of essential goods. It informs land use planning around hazardous sites. The canonical description is on the STEM Commons.
Layers of protection review
Published safety reports and incident investigations are used to show how independent barriers are arranged and where they share a common cause.
Land use around hazardous sites
Consequence zones for fire, explosion and toxic release are compared with nearby housing, schools and critical services, as planning authorities do under major hazard regulation.

06Validation
How results are checked.
Safety measures are verified through audits, inspection and proof testing. Incident investigations test whether barriers performed as intended.
| Check | How it is done |
|---|---|
| Incident learning check | Scenarios are tested against barrier failures documented in published investigations |
| Independence of barriers | Each barrier is checked for shared dependence on power, cooling water or staff |
| Regulatory boundary | Outputs are framed as context and never as a safety case, which remains the operator's duty and the regulator's judgement |
Natural hazards triggering industrial accidents are often not considered in design. Organisational drift can erode barriers over time.
07Simulator
A cascade through interdependent networks.
A hazard footprint takes out co-located assets in every layer; fragmentation, dependency between layers and overload of the survivors then spread the failure. The 3D view separates the layers by depth. Teaching model with stated illustrative values, not a prediction. The map on this page shows Europe; the model itself is not tied to a place.

Model process safety at energy facilities as a system. Run the cascade.
Assembled from the Nexus Standards area profile Energy risk standards: the hazards it names, the systems and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.
