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 industry and robotics, work and skills and trade, resources and supply chains, 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.
Layer of protection analysis
The independence and reliability of safeguards against each hazardous scenario are assessed to decide whether more protection is needed.
Management of change
Modifications to plant, procedures and staffing are reviewed for safety effects before they are made, preventing drift.

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 |
|---|---|
| Study team competence | Hazard studies are led by qualified facilitators |
| Independence of layers | Safeguards are checked for shared failure causes |
| Action closure | Study recommendations are tracked to completion |
Natural hazards triggering industrial accidents are often not considered in design. Organisational drift can erode barriers over time.
07Twin and cascade simulator
Model process safety engineering as a system. Run the cascade.
Assembled from the Nexus Standards area profile Industry and manufacturing: 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.

How process safety engineering is modelled, measured and tested.
The model, its assumptions, its data and its uncertainty, in the form a scientist or engineer would check. Structures follow published methods. The values drawn are illustrative, not findings.
System model
The couplings between the systems in process safety engineering: signs of influence, a reinforcing and a balancing loop, and cross-links where stress jumps.

10Stewardship
Who maintains the method.
Advanced Industry and Robotics stewards process and industrial safety engineering for the Consortium and reviews how it is applied across platforms.
11Process
How the process runs.
Process
Process safety engineering: Risk management process
ISO 31000:2018 sets out an iterative risk management process, from scope, context and criteria through assessment and treatment to monitoring, review and reporting.
01 Frame
- 01Scope, context and criteriaDataset · Automation engineerThe frame for the process: the scope, the external and internal context, and the risk criteria. Later steps are read against this frame.
02 Risk assessment
- 04Risk identificationStep · Automation engineerThe first part of risk assessment. Risk is usually expressed by risk sources, potential events, their consequences and likelihood.
- 05Risk analysisModel · Automation engineerThe second part of risk assessment. It considers consequences and likelihood of the identified risks, with guidelines, not a formula.
- 06Risk evaluationStep · Automation engineerThe last part of risk assessment. Results of the analysis are compared with the risk criteria to see where more action is needed.
03 Treatment
- 07Risk treatmentStep · Automation engineerTreatment options are selected, then plans are prepared and implemented. Residual risk is documented and goes to monitoring and review.
04 Across the process
- 02Communication and consultationStep · Automation engineerCommunication and consultation with stakeholders is its own process element. The standard draws it alongside the others, not in sequence.
- 03Monitoring and reviewStep · Automation engineerMonitoring and review take place at every stage. New experience, knowledge and analysis can revise elements, actions and controls.
05 Record and report
- 08Recording and reportingRecord · Automation engineerThe process and its outcomes are documented and reported. The standard does not name who receives the report in the clauses read.
Outline of an external standard or method, from its public sources. It describes what the framework says, not a record of any run. It does not show that Nexus or any partner performs, certifies or approves a step. A gate is a step of the method, never a Nexus approval.
12Questions
Questions and answers.
What are the limits of process and industrial safety engineering in this field?
Natural hazards triggering industrial accidents are often not considered in design. Organisational drift can erode barriers over time.
How are results checked?
Safety measures are verified through audits, inspection and proof testing. Incident investigations test whether barriers performed as intended.
Are the values on this page real?
The data names, roles and checks are real descriptions of practice. The canvas shows a design of the method’s use, not a run; no result is reported here.
Where else is this method applied?
