An Integrated System for all Emergencies

LARGE FIRESIn the event of a large fire, emergency crews can use the Community Warning System to communicate with each other, with the public, with county officials, and with members of the media to keep everyone informed.

CHEMICAL ACCIDENTSDuring a chemical accident, the Community Warning System is used to notify emergency centers throughout the county. The system simultaneously notifies emergency crews, the media and local schools and hospitals. Safety sirens near the accident site are also activated to immediately warn local residents to “Shelter, Shut & Listen.”

EARTH QUAKESAfter an earthquake, the Community Warning System’s television, radio and media links can be used to provide residents with up-to-date local status reports regarding the availability of services, road conditions and resources throughout the county.

COMMUNITY WARNING SYSTEMTogether, these make up an all-hazard Community Warning System. Sirens are activated in the event of a chemical accident; the digital and radio communication links tie our county’s emergency services together to form one of the most sophisticated safety systems in the United States.

Second EditionRev. July, 2006

The following Shelter-In-Place procedures are recommended

as the best first response after the Safety Sirens are Sounded

Siren testing is scheduled for the first Wednesday of each month at 11:00 a.m. For more information about the “Shelter, shut & Listen” response, call (925) 313-9622

Program History1998 CAER begins donation of CWS to County

2001 CWS transfer to County complete; operation assigned to Health Services

All-Hazard Alerting

DHS “Target Capabilities List” (per HSPD-8):

Members of the public receive prompt, accurate and useful information regarding threats to their health, safety and property…

Performance Objectives:

• Time from incident to public alert < 30 min

• 90 percent of affected notified within 15 minutes

Contra Costa County Office of the Sheriff

Implications of All-Hazard Alerting• Challenge to hazard-specific semantics:

• E.g., what does a siren mean?

• Variety of public attitudes and experience

• Multiplicity of alert sources and alert targets

• Communicating uncertainty

• Heightened need for corroboration as messages become more unexpected…

The Common Alerting Protocol

• An international standard data format (XML) for coordinating multiple alerting systems

• Adopted by DHS, NOAA, USGS, California

• Consistent message across all systems

• Precise geographic targeting

• Basic text plus multilingual and “rich media”
