Air Quality Advisory 10/11/17

AIR QUALITY HEALTH ADVISORY — SMOKE
Wednesday, October 11 through Friday, October 13, 2017
Plumas and Sierra Counties
Plumas County Public Health and the Northern Sierra Air Quality Management District are extending a joint air quality advisory to notify the public of intermittent poor air quality at least through Friday, October 13, caused by numerous fires in California. Smoke may settle in lower areas at night and drift across Plumas and Sierra County during the day, depending on wind direction and other factors.

For the next several days, Plumas County’s Air Quality will continue to vary as Fire Crews work to contain the numerous fires. It is important to remember that smoke can be damaging to your health. Exposure to elevated PM2.5 (fine particulate matter in smoke) concentrations can result in eye and throat irritation, headaches, nausea, shortness of breath, congestion, coughing, impaired lung function and chest pain, especially among sensitive individuals such as the elderly, children, people with asthma, people with heart or lung conditions, pregnant women and anyone who is exercising or working hard outdoors.
If you smell or see smoke around you, the following actions are recommended:
Minimize outdoor activities even if you are healthy;
Stay indoors with doors and windows closed as much as possible; run the air conditioner on the “recirculate” setting if that is an option;
People with asthma should follow their asthma management plan;
People with heart disease, respiratory or chronic health issues should stay indoors;
Contact your doctor if you have symptoms of cough, shortness of breath, chest pain, or severe fatigue.

Here is a simplified way to estimate air quality risk categories with a visibility assessment:

When using the visibility index to determine smoke concentrations, it is important to:
• Face away from the sun.
• Determine the limit of your visibility range by looking for targets at known distances (miles). The visible range is the point at which even high-contrast objects (e.g., a forested mountain viewed against the sky at noon) totally disappear.

Smoke conditions can change quickly and vary greatly due to terrain, wind direction and weather. Western parts of Plumas and Sierra Counties are likely to see the most smoke. It is important to monitor the smoke and make outdoor plans accordingly.
The use of filter masks is generally not recommended because the most effective masks can reduce air flow for people who are already having breathing difficulty.
