- Use common sense. If it looks smoky outside it’s probably not a good time to go for a run. And it’s probably not a good time for your children to play outdoors.
- If you have a heart or lung disease, if you are an older adult, or if you have children, talk with your doctor about whether, and when, you should leave the area.
- If you decide to remain:
- Consider staying indoors to avoid breathing the smoke particles.
- Run your air conditioner, if you have one.
- Keep the fresh air intake closed, and the filters clean, to prevent bringing additional smoke inside. Note: if you don’t have an air conditioner, staying inside with the windows closed may be dangerous in extremely hot weather. In these cases, seek alternative shelters.
- A swamp cooler will not provide this protection, and will pull in the smoky air from outside.
- “Masks” (especially surgical masks or wet bandanas) will not protect your lungs. If the smoke is that irritating to you, the best option is to remain indoors or temporarily re-locate.
