Officials said a struck gas line let gas move into the house before it exploded.
IMPERIAL, Mo. — A house on White Haven Court in Imperial exploded Tuesday afternoon after a gas leak was reported, destroying the home and damaging nearby houses, authorities said. Fire officials said the family inside got out before the blast and no injuries were reported.
The explosion set off an investigation by the Missouri State Fire Marshal’s office and renewed attention on the risk that comes when underground utility lines are hit during excavation work. Officials said the blast happened after a line was struck during work to bury fiber optic cable in the area, allowing gas to seep into the home.
Rock Community Fire Protection District firefighters were first called to the subdivision around noon on March 3 after a gas leak was reported outside the home, officials said. Firefighters evacuated a mother and four young children from the house, according to the fire district. Neighbors said the situation changed quickly. “I just heard a boom,” Tony Mercer, who lives a couple of houses away, said. “It like shook my house.”
Within minutes, neighbors saw smoke and debris where the house had stood. A neighbor who asked to be identified only by the last name Krones said the front of the home appeared to collapse into the driveway, where a vehicle was parked. Officials said the explosion destroyed the house and blew out windows in two nearby homes. A second house near the blast was damaged by fire, and crews worked through the afternoon to put out flames and deal with hot spots, the fire district said.
Spire, the regional natural gas utility, said it was notified that a third-party excavator working for another utility struck a gas line in the subdivision. In a written statement, the company said it took action with firefighters to evacuate nearby homes and stop the leak, but gas migrated into a home and the explosion occurred. The statement said the company was working with investigators to determine what happened and that its thoughts were with those affected.
Officials did not immediately release the names of the residents or say how long the family had lived in the home. Fire officials said the residents escaped in time, but the blast still brought losses. Fire service reporting based on local accounts said two family cats were believed to have died. Authorities did not give a damage estimate Tuesday, but photos and witness descriptions showed the home largely leveled and debris scattered across the street and yards.
The fire district said a crew burying fiber optic cable hit a gas line, but it was not clear which contractor struck it. Such investigations often look at where the line was located, how it was marked, the equipment used, and what steps were taken after the strike was discovered. The fire marshal’s office typically reviews scene evidence and works with local fire agencies and utilities, and it can bring in additional experts when needed.
The response in Imperial drew help from neighboring agencies. The Antonia Fire Protection District assisted Rock firefighters at the scene, and the Rock Township Ambulance District also responded, officials said. Neighbors gathered at the edge of the area as crews worked, some describing how the sound carried through the subdivision and left homes rattled.
Gas-related explosions tied to digging and line strikes have drawn scrutiny in Missouri in recent years, including incidents that prompted federal reviews of marking and emergency response practices. Investigators in those cases have examined how quickly residents were warned, what was evacuated, and how the flow of gas was stopped once a leak was reported. Officials in Jefferson County did not say Tuesday whether any federal agency would take part in this investigation.
By late Tuesday, firefighters said the immediate fire had been contained, and investigators were working to document the scene and gather information from utilities and witnesses. Officials said the investigation would continue Wednesday, March 4, as crews assessed damage to nearby homes and worked to determine the exact sequence of events leading to the blast.
