Process Fire Engineering
The application of risk-informed, performance-based fire protection in the process sector. An approach that uses risk assessment to design and implement fire protection measures rather than relying on often onerous prescriptive standards.

Quantitative Fire Escalation Risk Assessment Model
Utilising a quantitative, performance‑based fire escalation risk assessment for facilities handling flammable liquids and gas. This methodology delivers a defensible engineering basis for evaluating fire escalation potential, mitigation effectiveness, and the proportionality of fire protection investment.
The objective of the escalation model is to quantify credible fire escalation risk, comparing worst‑case (unmitigated) and mitigated outcomes in order to:
-
Identify time‑critical escalation mechanisms
-
Define required fire protection response performance
-
Quantify risk reduction achieved by mitigation
-
Establish a proportionate and defensible cost‑benefit basis for fire protection systems
​​​​
​
​
Proportionality and Cost‑Benefit Assessment
​
​​​Risk reduction is quantified as the difference between worst‑case and mitigated Expected Value (ΔEV). This is used to establish a proportional spend envelope, applying a defined proportionality factor to determine the maximum reasonable annualised investment in fire protection.
This framework enables demonstration that mitigation measures:
​
-
Deliver measurable risk reduction
-
Are not grossly disproportionate to the risk mitigated
-
Are appropriately targeted at time‑critical escalation scenarios
Where systems mitigate multiple scenarios, benefits are rationally apportioned to ensure transparent and auditable justification.
Guidance on the Fire Hazard Management Process
1. Define the Scope
Clearly define the scope and purpose before starting a fire hazard assessment. This ensures that time and resources are focused on elements that add value and that the chosen methodology directly supports the study’s objectives.
​
2. Scenario Development
A range of analytical tools, such as Quantitative Risk Assessment (QRA), Hazard and Operability Study (HAZOP), and event tree analysis are recommended for fire scenario analysis. Event tree analysis is particularly useful for illustrating how the success or failure of mitigation barriers can influence scenario outcomes and for evaluating the effectiveness of fire protection measures.
​
3. Risk and Protection Measures
Review approaches to fire risk reduction. While prescriptive measures are straightforward, they may not always be cost-effective relative to the risk reduction achieved. An often preferred approach is to use cost-benefit analysis to demonstrate that fire protection measures reduce risk to a level that is as low as reasonably practicable (ALARP).
​
4. Fire Hazard Management Plan (FHMP)
A Fire Hazard Management Plan is a structured, risk-based strategy for identifying, assessing, and controlling fire hazards within a facility or operation. The FHMP should document the assessment methods, rationale for decisions, and demonstrate that risks are managed appropriately. The plan should be integrated into the overall fire hazard management strategy of the organisation.
