The primary culprits for smoke in the United States on October 8, 2020 are the Red Salmon and August Fires that have been burning for weeks in Northern California, a few scattered fires in Oregon and Idaho, three fires in Colorado and Wyoming, one in northeast Utah, and the Cow Canyon Fire on the Arizona-New Mexico border.

Breathing smoke

Photographers at a wildland fire may be able to use and tolerate a mask that traps 95 percent of the 0.3 micron particulates in smoke, but the devices are not practical for firefighters. (see photo above)

In case you are wondering, masks and respirators are divided into rating classes: N is not oil resistant, R is oil resistant, and P is oil proof. The number, such as 95, refers to the percent of particles removed that are at least 0.3 microns in diameter.

Be careful out there.

It is interesting that the air quality maps (above) do not detect or predict a serious air quality issue in Colorado around the Mullen Fire.
