Droves of Sonoma County residents wore white respirator masks over their faces last November as noxious smoke from the Camp fire 100 miles to the north cast a dark pall over the Bay Area, creating the foulest air ever recorded in the region. As a direct result of that pollution, California employers are now required to protect all workers — except for those in closed buildings with filtered air — from wildfire smoke whenever the air is officially deemed unhealthy to breathe.
