## What is Visual Accident Perimeter?

The Visual accident Perimeter helps emergency responders to quickly evaluate dangerous situations. VAP will create a dispersion model based on your input on the Map.
All the different zones of the model are color-coded and the distance to each zone is displayed on-screen, in the corresponding color.
The extensive database from BIG can be used to select the dangerous substance in question. (There is also an option to enter these parameters manually.)
The entire app and all the data is available in four languages: English, German, French and Dutch.
Use our Kaleidos app to gain access to even more useful data regarding the substance.
