Small Iowa city evacuated due to chemical fire

NORTHWOOD, Iowa (AP) — Authorities are evacuating residents of a small northern Iowa city where firefighters are battling a chemical fire.

The Worth County Sheriff's Office says an evacuation order is in place for Northwood due to a fire Thursday morning at a fertilizer plant at Northwood Municipal Airport. No one is reported injured.

A National Weather Service alert says the fire contains sulfuric acid.

The Mason City Globe Gazette reports several residents heard explosions when the fire broke out. Highway 105, a main artery in Northwood, was blocked off near the fire.

The Iowa State Patrol, Northwood police and the sheriff's department are assisting at the scene.

Iowa Department of Homeland Security and Emergency Management spokeswoman Lucinda Robertson says residents are being sent to nearby Kensett.

Northwood has about 2,000 residents.
