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:

If it’s within your means, stay indoors, especially if you have respiratory issues, health concerns, or fall within the senior or child demographics.

Trim outdoor activities to essentials:

When you can’t avoid going outdoors, keep outdoor activities to the bare essentials. Reducing your time outdoors is the key.

Reduce pollution contributors:

Exercise prudence when it comes to activities that exacerbate pollution, such as driving cars, wielding gas-powered lawnmowers, or utilizing other motorized vehicles. Minimize their use during air quality alerts.

A ban on open burning:

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

Stay well-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 caution:

If you have respiratory problems or underlying health conditions, exercise extra caution. These conditions can increase your vulnerability to adverse effects from poor 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.
