This case study covers a Quantitative Risk Assessment (QRA) at an aviation fuel depot in Delhi — the same facility covered by this batch’s companion HAZOP case study, with HAZOP identifying hazard scenarios that this QRA subsequently quantified numerically, consistent with the sequential relationship covered in this project’s offshore platform and refinery HAZOP/QRA pairs. As explained in those companion pieces, QRA calculates individual risk (the probability a specific person at a specific location faces harm within a given time period) and societal risk (the relationship between the number of people affected and event frequency), using frequency analysis combined with consequence modeling specific to the facility’s hazard inventory and layout. For an aviation fuel depot, consequence modeling needs to account for the depot’s proximity to airport operations and, depending on location, surrounding urban development — a large flammable liquid release scenario’s consequence severity depends heavily on what’s actually near the depot, making site-specific consequence modeling particularly important rather than a generic template calculation. The assessment calculated risk contours across the depot’s storage and handling areas, comparing results against risk tolerability criteria to identify which risk-reduction measures — physical protection, procedural controls, or operational restrictions — would deliver the greatest safety improvement per unit of investment. NCRB recorded 7,566 fire accidents in India in 2022, and aviation fuel facilities, like the offshore platforms and refineries covered elsewhere in this project’s QRA content, carry disproportionate consequence severity relative to incident frequency given concentrated flammable liquid inventory. A QRA study for an aviation fuel depot of this scale typically costs ₹8–18 lakh. This case study covers what the QRA calculated and how site-specific consequence modeling shaped the findings.
This QRA at a Delhi aviation fuel depot built on the hazard scenarios identified in this batch’s companion HAZOP study, calculating individual and societal risk with consequence modeling that accounts for the depot’s proximity to airport operations and surrounding development — a site-specific factor that shapes results significantly.

Q5: What is individual vs. societal risk?
A Quantitative Risk Assessment (QRA) typically evaluates two important types of risk:
- Individual Risk (IR): The probability that a specific person at a particular location could be fatally affected by a hazardous event over a defined period. It is commonly represented using risk contour maps around the facility.
- Societal Risk (SR): The probability of an incident affecting multiple people simultaneously. It considers both the likelihood of an event and the number of people potentially exposed, helping assess the potential impact on workers, nearby communities, and surrounding infrastructure.
Evaluating both individual and societal risk enables organisations to understand not only the risk to individuals working at or near the facility but also the potential consequences of major accident scenarios involving multiple people.
