This Field Operations Guide for Disaster Assessment and Response (FOG) was developed by the U.S. Agency for International Development/Bureau for Humanitarian Response/Office of Foreign Disaster Assistance (OFDA) as a reference tool for individuals sent to disaster sites to perform initial assessments or to participate as members of an OFDA Disaster Assistance Response Team (DART). The FOG contains information on general responsibilities for disaster responders, formats and reference material for assessing and reporting on populations at risk, DART position descriptions and duty checklists, sample tracking and accounting forms, descriptions of OFDA stockpile commodities, general information related to disaster activities, information on working with the military in the field, and a glossary of acronyms and terms used by OFDA and other organizations with which OFDA works.
