Air quality alerts: Recommendations from the NWS

When an air quality alert is in effect, following the NWS guidance is pivotal. Here are some simple tips from the NWS for safeguarding your well-being:

Seek shelter indoors when possible:

Whenever possible, seek refuge indoors, especially if you grapple with respiratory concerns, health issues, or belong to the senior or child demographic

Curb outdoor exposure:

When venturing outside is unavoidable, restrict your time outdoors solely to essential activities. Reducing exposure is paramount.

Tackle pollution sources:

Be conscious of activities that contribute to pollution, such as driving cars, using gas-powered lawnmowers, or relying on motorized vehicles. Curtail their use during air quality alerts.

Banish open burning:

Avoid burning debris or any other materials during air quality alerts. This contributes to worsened air quality.

Stay informed:

Stay updated by tuning in to NOAA Weather Radio or your preferred weather news outlet. Staying informed helps you make wise choices regarding outdoor activities during air quality alerts.

Respiratory health matters:

If you grapple with respiratory issues or underlying health problems, exercise added caution. These conditions can render you more susceptible to the adverse effects of compromised air quality.

By adhering to the advice from the NWS, you can enhance your safety during air quality alerts while reducing your exposure to potentially harmful pollutants. Stay aware, stay protected, and make your health a top priority.
