FEAT combines large amounts of scientific insights and data into one simple tool for use in field-based situations. Assumptions are made in the FEAT, some of them approximate. FEAT was prepared as an account of work sponsored by the United Nations. Users of FEAT are responsible for their operations and functions. FEAT outputs will help to prioritize activities of relief and risk management teams, but cannot provide definitive scientific assessments or analysis. For example, FEAT cannot provide exact impact perimeters. Exact results will depend on individual cases and conditions. Users will need to set priorities based on actual field situations, which may differ from those presented.

FEAT is intended as guidance material only, and is not to be regarded as binding international regulation or legislation. FEAT does not reflect nor replace nor supersede national, regional or international legislation, regulations or policies. FEAT data have been derived from recognized scientific databanks of international authorities or institutions in good faith and on basis of information available at the date of publication. Resources include amongst others the European Chemicals Agency, UNECE Industrial Accidents Convention Directives and the US Environmental Protection Agency.

Neither the UN nor any of its agencies or employees make any warranty, expressed or implied, or assumes any legal liability or responsibility for the accuracy, completeness, or any third party's use or the results of such use of any information.
