COA MUNNITY WARNING SYSTEM DESCRIPTION
The Community Warning System(CWS) is an emergency warning system that consists of alert
and notification features. The alert and notification features,'linked by a radio frequency
backbone, function even when the telephone system fails. Signals carried by radio frequency
activate every part of the emergency system. The system's design features multiple back-ups
so that there is an excellent chance of the system surviving an earthquake; back-up power
supports each broadcast point, multiple radio frequencies carry activation signals and four
broadcast towers within the county microwave will carry broadcast signals.
ALERT PORTION
1. Sirens will be placed in the industrial corridor of the county. They will be used for
chemical accidents only.
2. Emergency Alert Receivers (EARS) will be placed in all schools (public and private),
hospitals, daycare canters, convalescent hospitals and other sensitive receptors in the..
industrial corridor of the county. The EARs can be used for any emergency. If a
school is in a flood plain during a flash flood alert, the county can send them a message
to evacuate, or that evacuation busses will be coming to get them.
I Pagers for emergency response personnel which operate via the radio_backbone
(independent of die phone system)can be used for any emergency. The County can
order a coordinated deployment of emergency responders via CWS to area of need
during a disaster.
NOTMCATION PORTION
CWS will interface with radio and television stations and transmit Contra Costa-specific
information to instruct citizens about the disaster and necessary actions to be taken by the
public. This part of CWS can be used for any emergency. In addition, if the radio stations in
San Francisco are destroyed and not able to broadcast the necessary information, CWS can
access rebroadcast points in this county and inform Contra Costa citizens via this route. These
features are particularly important to inform citizens about necessary actions after a devastating
earthquake.
It is possible to preprogram the system for potential disasters. Each chemical company,
refinery and water or waste water treatment plant(using acutely hazardous materials) will
participate in determining potential accidents and the proper emergency responses and public
notification plans will be programmed into the warning system.
Education of the Contra Costa citizens about CWS will have a general emergency preparedness
theme. All education efforts will focus on CWS and how it will inform the citizens, and
preparedness for: EARTHQUAKES, CHEMICAL ACCIDENTS, FIM, FLOODS, AND
THE PROPER USE OF 911.
