MCMINNVILLE, Ore. (AP) — A fire and related ammonia in the air at the Organic Valley Creamery in McMinnville Tuesday prompted an evacuation order for everyone within a half mile of the business.

McMinnville Police announced the evacuation at about 2:30 p.m. Tuesday because of ‘anhydrous ammonia’ being released as the fire burns, KATU-TV reported.

Anhydrous ammonia is a colorless gas with a pungent, suffocating odor, according to the Centers for Disease Control and Prevention.

Police said people under evacuation should go to West Wortman Park. No injuries had been reported.
