Smoke from numerous wildfires has created poor air quality in many parts of California.
The South Coast Air Quality Management District has warned that smoke and ash are probably blanketing much of Los Angeles, Orange, Riverside and San Bernardino counties because of two major fires in Southern California as well as several Northern California blazes.
The air district’s smoke advisory said that most of Southern California will be affected by smoke, with the highest readings of fine-particle pollution, tiny lung-damaging particles known as PM2.5, in areas closest to the Bobcat and El Dorado fires.

People with heart or lung disease (including asthma), the elderly and children should take extra precautions as they may be more likely to experience poor health if they breathe in wildfire smoke.
Avoid vigorous physical activity.
Run your air conditioner if you have one. Make sure it has a clean filter and that it is recirculating the indoor air to prevent bringing additional smoke inside.
Create a clean air space in your home by using a portable air cleaner instead of or in addition to your air conditioner. Do this in one or more rooms with the doors and windows closed.
Avoid using a whole-house fan or a swamp cooler with an outside air intake.
Avoid using indoor or outdoor wood-burning appliances, including fireplaces and candles.
Do not rely on dust masks for protection. Paper “dust masks†can block large particles such as sawdust, but do not protect your lungs from the small particles or gases in wildfire smoke. Disposable respirators such as N-95 or P-100 respirators can offer some protection if they are worn properly and have a tight fit.
Breathing in smoke can have immediate health effects:
