Chemical identification databases
Properties, hazards and protective actions for the product you think you have.

A meter reading, container marking, shipping document, weather observation and plume model each describe part of the incident. The challenge is turning those pieces into an actionable understanding of the hazard.
Properties, hazards and protective actions for the product you think you have.
The NOAA and EPA chemical database, including reactivity between products.
The Emergency Response Guidebook available where the identification is being made.
An estimate of where the product goes, built from inputs you supply.
Threat zones drawn against the actual streets, occupancies and populations at risk.
Readings collected into one record rather than written on a glove.
Listed alphabetically, not ranked. Everything below is reported by the company itself. Being listed is free and is not a recommendation — use the questions above when you talk to any of them.

Government, standards and peer-reviewed sources on this problem. Every address here was checked before it was published.
The current Emergency Response Guidebook, from the agency that publishes it.
Why it matters
The reference the initial isolation and protective action distances actually come from.
The chemical database, mapping and modeling tools NOAA and EPA provide to responders at no cost.
Why it matters
Free, government-maintained, and already the basis of what several commercial products present back to you.
Exposure limits, physical properties and protective equipment for several hundred substances.
Why it matters
The authority behind the numbers a detection product shows you.
Nothing here is paid placement. Links are chosen because they are the clearest explanation we could find, and labeled so you know who wrote them.
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?
