MOUNT VERNON, Wash. (AP) — Skagit County in northwest Washington state says it has provided about 2,000 N95 masks to protect agricultural workers amid the widespread wildfires. Thick smoke has made the air quality unhealthy and prompted orders for people to stay home as much as possible. The Skagit Valley Herald reports that the smoke is expected to linger until at least Thursday. Farmers were already required to wear masks due to the coronavirus pandemic. But the Centers for Disease Control and Prevention says cloth masks do little to protect from wildfire pollutants. Masks like the N95 can protect against the harmful particles found in smoke.
