How AgniKawach output is mapped to the major regulatory frameworks. Every QRA bundle can be exported to one of four packs; the pack is responsible for formatting and table layout, not for solver math.

India · PNGRB India · OISD UK / NI · COMAH EU · Seveso-III All four packs implemented

Solver outputs are framework-agnostic. Tier-1 + Tier-2 produce the same physical quantities (concentration, flux, overpressure, probit dose). The pack adapter formats them into the table layout each regulator expects. Module list lives at solvers/tier1/regulatory/.

INDIA · PNGRB ERDMP — Emergency Response & Disaster Management Plan IMPLEMENTED

Mandated by the Petroleum & Natural Gas Regulatory Board (Technical Standard TS-ERDMP-001) for all petroleum, natural gas, and LPG pipelines > 25 mm under ERDMP 2010 (amended 2019). AgniKawach generates the consequence-modelling annex.

What the pack produces

ERDMP requirement	AgniKawach output
Maximum credible accident (MCA) consequence distance	Tier-2 dispersion / fire / VCE distance to threshold (ERPG-2, 5 kW/m², 0.07 bar). Casebook ↗
Probit dose & fatality distance	Tier-1 `qra.py` — thermal (Eisenberg), overpressure (HSE 2010), toxic (TNO Green Book).
Land-use compatibility table	Risk-contour grid + receptor zone mapping → ERDMP Table 5 layout.
Branded PDF report	`solvers/tier1/regulatory/pngrb.py` · 11 unit tests · snapshot diff in CI.

INDIA · OISD OISD — Oil Industry Safety Directorate (116 / 118) IMPLEMENTED

Minimum-distance lookup based on inventory tonnage. AgniKawach reports both the regulatory minimum and the simulation-derived distance side by side, so the regulator can see the margin.

What the pack produces

OISD requirement	AgniKawach output
OISD-116 — Fire-protection distance	Inventory → table lookup + Tier-1 pool / jet-fire flux distances.
OISD-118 — Plant layout	Receptor zone + obstruction map; cross-references the geometry pipeline (Geometry Viewer ↗).
Cross-check	`solvers/tier1/regulatory/oisd.py` · 7 unit tests.

UK / NI · COMAH COMAH 2015 — Control of Major Accident Hazards IMPLEMENTED

Lower- vs upper-tier classification by substance × inventory; supporting consequence analysis attached to the COMAH Safety Report.

What the pack produces

COMAH requirement	AgniKawach output
Tier classification	Substance × inventory threshold lookup → Lower / Upper / Out-of-scope.
Predictable major accident (PMA) consequence	Tier-2 CFD result for each PMA; receptor flux / dose in COMAH-prescribed units.
Cross-check	`solvers/tier1/regulatory/comah.py` · 9 unit tests.

EU · SEVESO Seveso-III — Directive 2012/18/EU IMPLEMENTED

Substance-threshold lookup, additive aggregation rule, domino-effect grouping by neighbour distance.

What the pack produces

Seveso requirement	AgniKawach output
Lower- / upper-tier classification	Multi-substance additive aggregation rule.
Domino grouping	Neighbour-distance table; consequences propagated through receptor zones.
Notification document	Branded PDF; same Tier-2 input, regulator-specific layout.
Cross-check	`solvers/tier1/regulatory/seveso.py` · 14 unit tests.
