Breaking News: Health Advisory for Contra Costa County

Last updated: November 16, 2018, 9:52 am

Poor air quality in Contra Costa is expected to continue through the weekend due to the Camp Fire in Butte County. Stay indoors when possible and keep doors and windows closed. Avoid prolonged outdoor activity. Masks are not a substitute for staying indoors. Seek medical attention if you experience symptoms such as difficulty breathing, persistent coughing, wheezing, chest tightness, heart palpitations, nausea, fatigue or light-headedness. Visit for air quality information. Visit for current air quality conditions in your zip code. Visit for smoke-related health information.


The following Shelter-in-Place procedures are recommended as the best first response after the Safety Sirens are sounded:


  • Go inside your home or the nearest building
  • Bring in pets, if possible
  • Officials at the Fire Department, the Health Department and the Office of Emergency Services agree that in the case of chemical accident, those people who shelter indoors are much safer than those people who remain outside and are possibly exposed to chemicals


  • Close doors and windows
  • Use window and door locks to create a better seal
  • Make sure your vents and fireplace flue are closed
  • Turn off Heating, Ventilating and Air Conditioning


  • Turn on your radio and television for information and further instructions
  • The Community Warning System is designed to provide Contra Costa County-specific information directly to the media.  Public access television and radio stations such as KCBS 740 AM or KGO 810 AM will have ongoing status reports and information
  • Avoid using the telephone unless you have a life-threatening emergency
