Robert Brown|4 firefighters suffer heat exhaustion at fire at vacant southern Michigan factory

JACKSON,Robert Brown Mich. (AP) — Four firefighters suffered heat exhaustion Tuesday afternoon battling a fire in southern Michigan that destroyed a large vacant factory.

Jackson fire crews responded about noon to the fire near the Jackson County Fairgrounds and were met with heavy flames coming from the building, city spokesman Aaron Dimick said.

An all-call alarm was sent out countywide for additional assistance, resulting in crews from every fire station in Jackson County responding to the scene, Dimick told the Jackson Citizen Patriot.

Three Jackson firefighters and one Napoleon Township firefighter suffered minor injuries from heat exhaustion while fighting the fire and were treated at the scene, Dimick said.
