Wildfire & Smoke Resources


  • COVID-19 & Wildfire & Masks.  The combination of wildfire and COVID-19 is a brand-new phenomenon.  Please be aware that cloth masks used to slow the spread of COVID-19 do not catch small, harmful particles in smoke that can harm your health.  The best way to protect yourself is to stay indoors if possible during wildfire events.  If you must remain outdoors in unhealthy air for extended periods due to work or other factors you may particularly benefit from an N-95 mask or respirator if approved by your physician.  Always wear a mask or facial covering to prevent the spread of COVID when you go outside your home.  KQED provides an excellent overview, and as always, please consult with your physician regarding what is appropriate for your health and situation.
