As smoke from Oregon wildfires continues to blanket the Mt. Shasta area, the Siskiyou County’s Public Health Officer Dr. Stephen Perlman has offered strategies to reduce smoke exposure.

As of Wednesday morning, the Douglas Complex fires had grown to 25,396 acres and were five percent contained, according to Inciweb, the Forest Service’s online information website.

Smoke from the fires, which are burning near Glendale, north of Grants Pass, Oregon, have impacted air quality as far south as the San Francisco Bay Area, according to reports from NBC Bay Area Tuesday morning.

In Siskiyou County, air quality is fluctuating between normal, moderate and unhealthy levels of smoke due to shifting winds.

Perlman encouraged residents with lung or heart disease and the elderly to leave areas where levels of particulate matter are high. Prolonged or heavy exertion should be avoided outdoors when the air is poor.

Following are strategies Perlman offers to reduce smoke exposure:

• Stay indoors to keep indoor air as clean as possible. Keep windows and doors closed.

• Reduce physical activity

• Reduce other sources of air pollution such as spraying aerosol cans, vacuuming, frying foods, etc.

• Keep car windows closed while driving and run the air conditioner on the inside air setting.

• Consult your physician if you have any concerns about your health condition.
