Most of a storage building near Gravois Mills was destroyed in a fire early Monday morning along with renters’ contents.

The Gravois Fire Protection District was dispatched for a fire at Storage Depot, 29322 Highway 5, just south of State Route P on the west side of the highway, at 3:24 a.m. April 2, 2018. Arriving on scene soon after, Gravois firefighters found one of two storage buildings, the one furthest back from the road, about 50 percent involved in fire, according to Chief Ed Hancock.

With mutual aid from Stover and Versailles Rural departments, the fire was marked under control around 7:30 a.m. though some fire continued as crews allowed the already destroyed portion to burn itself out.

According to Hancock, storage unit fires can take more time to control due to a typically heavy fuel potential from all of the items inside which can run the gamut in nature.

“They can be fairly dangerous because you don’t know what you’re dealing with,” he said.

Firefighters were able to limit damage to a total loss of 75 percent of the structure. The few remaining units had some smoke and water damage, but items could be recovered.

The fire is under investigation by the Missouri State Fire Marshal’s Office. An area of origin has been determined but not the cause, said Hancock.

While the grounds had electricity for lighting, individual units did not have electricity. Fires at storage units are not that unusual, according to Hancock, due to the wide variety of materials that people may put in them.
