Straight from the horses mouth:
[quote:094d7]In the event of a terrorist attack,
natural disaster or other large-scale emergency, the
Department of Homeland Security will assume primary responsibility on March 1st for ensuring that emergency response professionals are prepared for any situation. This will entail providing a coordinated, comprehensive federal response to any large-scale crisis and mounting a swift and effective recovery effort. The new Department will also prioritize the important issue of citizen preparedness. Educating America's families on how best to prepare their homes for a disaster and tips for citizens on how to respond in a crisis will be given special attention at DHS.[/quote:094d7]
