Forms Of Communication

During a major emergency, City of Chicago officials will work to provide timely, accurate information to the public. The City has several public information procedures and/or tools in place that may be used during a major emergency or disaster.

City of Chicago officials will coordinate with all members of the media, radio and television, to deliver accurate information to the public.

This system will send a recorded message to telephones in a geographically specified area or to a pre-programmed list of contacts

Emergency Warning System (EWS):
EWS an outdoor, all-hazards siren system that is used to warn the general population of a potential danger in a short amount of time and to notify them that the emergency has passed.
