All-Hazards Warning Law and Legal Definition
All-hazards warning is a system that serves as the link between the technical groups that have knowledge about a hazard and those that need the information. In other words it means the ability to broadcast emergency information to the public before, during, and after disaster. A unified warning system will provide the public, companies, and emergency responders with a single source of information on all hazards. Such a system can help the technical groups to take advantage of the current ideas about how best to convey warnings to the entire population. In order to provide emergency alerts that reach the right people, in a timely manner and in a way that is meaningful and understood by all, the advocates of all-hazards warning systems seek interoperability among warning systems, standardized terminology, and operating procedures.
