Company spokesperson Olivia Koch told CNN the incident occurred in Gleannloch Farms, near Spring, Texas.
Officials evacuated residents from the area and set up a 500-foot perimeter around the scene, according to another post from the HCFMO.
In addition to those injured, at least one home was damaged in the fire, according to the Marshal’s office.
Electric service was also interrupted for about 800 customers in the area due to damage to some electrical equipment, Centerpoint’s Koch said.
Crews from CenterPoint Energy will begin repairs to restore service to both natural gas and electricity customers impacted by the incident once the scene is safe, she added.
