If you have low tolerance for smoke, please take the following precautions to reduce your exposure.

  • Stay indoors as much as possible especially seniors and children.  Avoid physical exertion.
  • Close windows, doors, and outside vents when it is smoky.  Use a fan or air conditioner to re-circulate the air.  Ventilate your home and work place during periods when it is least smoky.
  • Drink lots of water, eat a balanced diet, and get adequate rest.  Good health strengthens your immune system.
  • Wearing paper masks will generally not protect your lungs from wildland fire smoke.
  • Be diligent about taking medicines prescribed by your doctor if you have pre-existing respiratory problems.
  • If, after following these guidelines, you still experience discomfort while breathing, consult your physician.
