In government parlance, Boom is the detonation of an explosive device, initially used in speaking of a nuclear bomb. Those steeped in disaster preparedness and response now speak in terms of “left of boom” and “right of boom.” Left of boom is the planning and preparation that goes into ensuring that a device never detonates and right of boom deals with responding to a disaster, generally the man-made type. Much of what organizations do is to address left of boom.
