Civil defense is a planned, coordinated action to protect the population during any emergency whether arising from thermonuclear attack or natural disaster. The Federal Government has assumed four responsibilities--(1) to keep track of the nature of the threat which the civil defense program must meet, (2) to prepare and disseminate information about the threat and how it can be met, (3) to bear a major part of the costs of certain kinds of civil defense activities, and (4) to provide technical assistance through state and local channels for civil defense planning. A protection program in the school is an essential instructional and administrative element. Major aspects of a survey of school locale include--(1) survey of existing shelter potential, (2) man-made hazards, (3) natural disasters, and (4) human resources. (LD)
