"Public information efforts should begin well in advance of an incident or planned event and may involve a combination of planning, resource gathering, organizing, and training and exercises. Public information planning allows for lifesaving measures such as evacuation routes, alert systems, and other public safety information, to be coordinated and communicated to diverse audiences in a timely, consistent manner. Public education contributes to preparing citizens to respond to a variety of hazards". (FEMA, FEMA 517, Nov 2007, p. 4)
