PEOPLE WITH SMOKE-AFFECTED HEALTH CONDITIONS SHOULD CONSIDER GOING TO A SMOKE-FREE AREA WHEN SMOKE IS PRESENT

August 19, 2020 – The Mariposa County Public Health website reminds residents that you can check the current air quality in Mariposa County by visiting the airnow website and scroll to Mariposa on the map.

You can also see the low-tech sensor network of purple air sensors around the county at purpleair (website). These sensors are an indicator of air quality status, but they are not as accurate as the emergency response monitors we use during a local fire. In side-by-side comparisons with our high-tech monitors they read high, sometimes reporting conditions significantly higher than actual conditions.

The circles/triangles are monitoring sites. Their color is related to the AQI levels below.

    • 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 the best time for your children to play outside.

    • If you have heart or lung disease, are elderly, or have children, ask your doctor if and when you should leave the area.

    • If you decide to stay:
        • Consider staying indoors to avoid breathing smoke particles.

        • Run your air conditioner, if you have one.

        • Keep the fresh air intake closed and the filters clean to avoid bringing additional smoke inside. Note: If you don’t have an air conditioner, staying indoors with the windows closed can be dangerous in extremely hot weather. In these cases, look for alternative shelters.

        • A swamp cooler will not provide this protection and will draw in smoky air from outside.

        • “Masks” (especially surgical masks or wet bandanas) will not protect your lungs. If the smoke is so irritating to you, the best option is to stay indoors or move out temporarily.
