This case study covers a Quantitative Risk Assessment (QRA) at a gas distribution station in Pune — the same facility covered by this batch’s companion HAZOP study, with the pressure-regulation and odorisation hazard scenarios identified there feeding into this QRA’s numerical risk calculation. Gas distribution station QRA carries a consequence-modeling consideration that echoes the LPG bottling plant content covered in an earlier batch: distribution stations, by the nature of serving local end-user networks, are frequently sited closer to residential and commercial development than upstream compression or processing facilities, meaning societal risk calculations (accounting for the number of people potentially affected) carry particular weight here relative to a more isolated upstream facility’s assessment. The assessment calculated risk contours across the pressure regulation, metering, and odorisation systems identified in the companion HAZOP study, modeling consequence scenarios for both a contained station-level release and — reflecting the regulator failure risk identified in that HAZOP — a downstream over-pressurisation event affecting the broader distribution network, comparing results against risk tolerability criteria with particular attention to the station’s proximity to surrounding development. NCRB recorded 7,566 fire accidents in India in 2022, and gas distribution stations combine a smaller individual gas inventory than upstream facilities with the specific consequence-propagation and proximity-to-development considerations this QRA specifically addressed. A QRA study for a gas distribution station of this scale typically costs ₹7–16 lakh. This case study covers what the QRA calculated and how the station’s proximity to surrounding development and its network-propagation risk shaped the consequence modeling approach.
This QRA at a Pune gas distribution station weighted societal risk particularly heavily, echoing the LPG bottling plant content covered elsewhere in this project — distribution stations are frequently sited closer to residential development than upstream facilities, given their role serving local end-user networks.

FAQs
Q1: How much does this QRA study cost?
The available source material does not provide a verified project-specific fee for this QRA. QRA pricing depends on facility size, hazardous inventory, number of credible scenarios, consequence modelling requirements, surrounding population/development, documentation available, and reporting scope. Elion’s QRA framework indicates that small single-hazard facilities can require less effort, while facilities with multiple process units require substantially more modelling and analysis.
Q2: How does this relate to Elion’s HAZOP at the same facility?
The HAZOP and QRA are complementary. HAZOP identifies process deviations, causes, consequences, and safeguards, while QRA quantitatively evaluates credible hazardous scenarios using frequency and consequence modelling. Elion’s QRA methodology specifically describes QRA as taking credible scenarios, many of which can originate from HAZOP, and quantifying their frequency and consequences.
Q3: Why does proximity to development matter for this QRA?
Nearby residential, commercial, industrial, or other occupied development matters because QRA evaluates not only risk to people inside the facility but also potential off-site population exposure. Elion’s QRA framework includes individual and societal risk, risk contours, Emergency Planning Zone (EPZ) delineation, and land-use planning decisions.
This means changes or existing development around the facility can materially affect the interpretation of risk and the need for additional safeguards or emergency-planning measures.
Q4: How does this compare to Elion’s LPG bottling plant QRA?
Both assessments use the same fundamental QRA framework—hazard scenario identification, frequency analysis, consequence modelling, and individual/societal risk evaluation—but the hazard sources differ by facility type. LPG bottling plants are specifically covered under OISD-STD-144, while other petroleum and LPG installations may fall under different OISD standards.
For an LPG bottling plant, the analysis is typically centred on LPG storage, filling, transfer and release scenarios. The present facility should be compared based on its actual inventory, process configuration and modelled scenarios rather than assuming the LPG bottling scenario set applies unchanged.
Q5: What consequence scenarios were modeled?
The exact scenario register for this particular QRA is not available in the retrieved source material, so specific scenarios should not be presented as confirmed findings. Elion’s general QRA methodology identifies consequence modelling for scenarios such as fires, explosions and toxic releases, with outputs including thermal-radiation zones, overpressure contours and toxic-dispersion footprints where applicable.
