The hazard changes while we are operating

Wind, release rate, product behavior, fire involvement, container condition and responder actions may all change the operational picture. Monitoring must continue after the initial characterization.

Technology approaches

Remote monitoring

Continued observation of the release without keeping people in position to make it.

Weather stations

On-scene wind and conditions, because the regional forecast is not the incident.

Continuous gas monitoring

Trend over time rather than the single reading taken on arrival.

ALOHA modeling

NOAA and EPA plume modeling. The output follows the inputs and assumptions, and is not an exact prediction.

UAS reassessment

Flying the scene again to see what has changed rather than assuming it has not.

GIS threat-zone updates

Redrawing the zones when the wind, the release or the container condition moves.

Plume modeling and monitoring

Modeled dispersion checked against monitoring, so the picture is corrected as conditions change.

Before you buy

  • A model is only as good as its weather input. Ask where that comes from.

Evidence and research

Government, standards and peer-reviewed sources on this problem. Every address here was checked before it was published.

Official resourceNOAA and EPA

ALOHA

The atmospheric dispersion model used to estimate threat zones from a chemical release.

Why it matters

Widely used, free, and worth understanding directly rather than through a product that embeds it.

Official resourceNOAA

ALOHA's Limitations

NOAA's own account of what ALOHA does not model well and where its estimates break down.

Why it matters

ALOHA is a model. Its output depends on the scenario inputs and assumptions you give it, and should never be represented as an exact prediction. Read this before a threat zone drawn on a screen is treated as a fact.

What departments are asking

Mutual Aid

Drone platform for hazmat monitoring — what are people flying?

Need something that can carry a four-gas meter and survive decon. Our current airframe is not rated for it. What sensor are you carrying, and has it been validated in that configuration rather than on a bench? How are readings transmitted, and at what stand-off distance? How does decon affect the aircraft, and is the platform treated as disposable once it is contaminated? What is your plan if communications fail while it is over the release?
