This handbook is designed to assist persons who are concerned with preventing or minimizing property damage to schools through vandalism, arson, and theft, and with avoiding bodily injuries in and around school buildings. Many of the suggestions, while directed at the planning of new buildings, can be adapted to lessen the incidence of vandalism and injury in existing buildings. The guide treats six aspects of a total security system: the school site, including grounds, roads, parking lots, and play areas; the exteriors of buildings, including hidden spaces, doors, windows, locks, and lights; the interiors of buildings, including community areas, laboratories, shops, and classrooms; the location and protection of fire alarms, exits, trash containers, mirrors, and lockers; internal security, including alarm systems; and deterrent programs such as school watchers, security officers, and live-in or 24-hour custodial services.
