The American Red Cross is an independent, voluntary body dedicated to performing the relief obligations entrusted to it by the Congress of the United States. The American Red Cross is required by congressional charter (Act of Congress of January 5, 1905, as amended, 36 U.S. Code 3, Fifth) to undertake relief activities for the purpose of mitigating the suffering caused by disasters. A disaster is an occurrence such as a hurricane, tornado, storm, flood, highwater, wind-driven water, tidal wave, earthquake, drought, blizzard, pestilence, famine, fire, explosion, building collapse, transportation wreck, or other situation that causes human suffering or creates human needs that victims cannot alleviate without assistance.

Through internal planning, policy setting, and implementation, and cooperation with private and governmental bodies, the American Red Cross at all levels gives priority to preparing for and providing assistance in disasters of any size.
