(Radio Iowa) – Emergency officials are recommending that residents of the south-central Iowa town of Otley evacuate or shelter in place due to a smouldering fire at a co-op. The fire at the Two Rivers Cooperative fertilizer storage facility started early Monday afternoon and officials say it could smoulder for several days. The main concern is burning sulfur, which can cause respiratory issues. The facility had 265 tons of sulfur when the fire started, plus even larger amounts of other farm chemicals like potash and urea.

About 800 people live in Otley and emergency officials say people who live near the town should consider evacuating or remaining inside due to air quality concerns.
