A 3-alarm fire that tore through storage units at 10 a.m. on Thursday, at Affordable Storage, 819 W. Kansas St. in McPherson destroyed the contents of 11 storage units and caused more than $100,000 in damage, T.J. Wyssmann, Deputy Fire Chief with the McPherson Fire Department, said. 

He said belongings in all of the units in the building are expected to have heavy smoke damage from the fire. Unlike a house, a storage unit's walls do not touch the roofline allowing fire and smoke to spread quickly throughout the structure, Wyssmann said.

About 15 firefighters on the scene had the blaze contained within 16 minutes of arrival. Additional emergency medical services were requested for rehabilitation efforts of personnel as multiple firefighters suffered heat exhaustion. One firefighter was transported to the hospital, but has since returned to duty.

Galva's Fire Department sent over crews to cover McPherson's response district while the city's firefighters worked to contain the blaze. 

McPherson's fire department and police department are investigating the cause of the fire with the aid of the Kansas State Fire Marshall Office. An Arson K-9 has been requested from the agency.
