Firefighters are battling a fire at a large building Monday in Montgomery County.

The fire was reported at 12:37 p.m. at 2119 Old Ox Road after reports of a fire explosion.

The Spring Fire Department is at the scene. Firefighters said four buildings apart of a compound are on fire. Officials said two of those buildings are residential and the other two appear to be commercial. Officials said people were inside the building but all escaped.

Officials said one person received non-life-threatening burns when a flash fire occurred in a building to a two-story home.

There are about 60-70 firefighters working the scene. The Woodlands Fire Department, Spring Fire Department, Porter Fire Department, East County Fire, and Montgomery County Fire Marshal’s Office are all assisting with the fire.

Officials said the area does not have a lot of water supply and six tankers had to be called out to help supply water to put out the fire.
