At least eight people were taken to a hospital after experiencing symptoms related to an unknown odor that was causing respiratory issues in Seattle, Washington.
Eight of them were taken to a hospital while the other two declined further medical care. One person, a 54-year-old woman, was transported to the hospital in serious condition. The three firefighters were all in stable condition and were taken to the hospital for further evaluation, fire officials said.
Firefighters ventilated the area to remove the substance. Hazmat crews confirmed the substance was an airborne respiratory irritant, but officials did not specifically say what it was.
