The Flash Environmental Assessment Tool (FEAT) is a tool created by the UN Environment/OCHA Joint Unit and its partners, notably the Netherlands National Institute for Public Health and the Environment.

FEAT is used to identify existing or potential acute impacts posed by chemical substances. It flags the spatial, human health and environmental impacts of chemical releases and allows responders to take quick action and alleviate human suffering. 

The is used by humanitarians, national authorities, industrial actors, regional responders and search and rescue teams. It identifies priority chemical risks following a disaster or conflict and provides advice on how to mitigate the human, livelihoods and environmental impacts of these events. 

FEAT can be used remotely and in the field by individuals with no environmental background. It combines scientific rigor with the practical needs of non-environmentalists operating in disaster settings. It is available in English, French, Spanish and Russian. A detailed FEAT Reference Guide provides advice on how to use FEAT for , as well as information on the underlying science.

The UN Environment/OCHA Joint Unit also hosts a free online course to introduce the FEAT. You can take the course at the following link:

Quantity - Exposure - Hazard

The FEAT uses a basic formula of quantity, exposure and hazard. FEAT works according to the hazard classification system of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), which is also included in the FEAT guide. It also provides a basic checklist to simplify the impact . This enables humanitarians with no scientific or environmental background to make a rapid assessment of the environmental impacts of emergencies, which may trigger human health in the long term.
