Screening answers, in your browser
Every safety study starts with a screening calculation: a first, fast estimate that tells you whether the question is serious enough to deserve a proper one.
These run entirely on your own machine. Nothing you type is sent anywhere and nothing is stored, so a scenario you try here stays yours.
They are not the product. The platform AgniKawach builds is a separate thing, with its own address and its own name, and it is in development. What the platform does.
Life-threatening concentrations reach 120 m downwind.
- DiscomfortAEGL-1to 910 mNoticeable irritation. Reversible once the cloud passes.
- Escape impairedAEGL-2to 350 mSerious, lasting effects. People here may not be able to walk out.
- Life-threateningAEGL-3to 120 mAn hour in here is expected to kill.
One fixed case at 4 m/s under overcast skies — computed here, not drawn. The zones are where the concentration crosses each threshold.

If this leaks, how far does it reach?
A vapour release through a hole in a pipe or a vessel. Set the substance, the size of the hole and the weather, and see how far the flammable cloud or the toxic concentrations travel downwind, and what is inside that boundary.
Choked-orifice discharge into a Pasquill-Gifford Gaussian plume, on Briggs (1973) open-country coefficients.

What these are, and are not
These are screening models: point sources on flat open ground, with no terrain, no buildings, no pipe racks and no jet momentum. Each one states its own range and warns you when your settings fall outside it.
They are demonstrations, not deliverables. Do not use a figure from this page for design, siting, emergency planning or a safety report — a screening correlation used outside its range is the most common way a consequence number goes wrong, which is the whole reason the platform exists.
