UPDATE on Oct. 28, 2022: On the fifth day since the Wilbur-Ellis Fertilizer plant caught fire in Moses Lake, local authorities are extending a health advisory due to the smoldering fire and continuous smoke in the area.

According to the Grant County Sheriff’s Office, smoke and gases are still damaging air quality in the vicinity of the blaze. Although these particulates are still present, the Washington Department of Ecology and the U.S. Environmental Protection Agency are monitoring a decrease in their potency east of the fire.

However, because of the contents of the plant, Sulfur dioxide has been detected in the air. Grant County officials say that some people exposed to this colorless gas may experience “irritations to the eyes, nose, throat and airways. SO₂ symptoms may include nasal congestion, eye irritation, burning or tearing choking, cough, airway irritation such as wheezing, burning or shortness of breath.”

If you’re experiencing these symptoms, it’d be wise to contact a healthcare provider to discuss the next steps. Although it won’t stop with sulfur dioxide exposure, wearing an N95 mask while in afflicted areas will help prevent the inhalation of particulates.
