PLUM, Pa. —
Family members of the six people killed in a house explosion nearly two years ago in Plum, Allegheny County, have filed lawsuits against multiple companies.
On Aug. 12, 2023, an explosion in the Rustic Ridge neighborhood claimed the lives of six people, including a child.
The victims:
The lawsuit alleges negligence and wrongful death against multiple companies. According to the plaintiffs, a pipeline leak caused one of the homes to be filled with flammable gas.
It alleges a failure to vent an over-pressurized gas line led to the disaster, destroying three homes in the neighborhood and damaging dozens more.
Attorney Ben Baer, who represents the children of Heather and Paul Oravitz, talked to Pittsburgh’s Action News 4 on Tuesday.
“These are people that have suffered an unimaginable tragedy. My clients are a young brother and sister in their early twenties that have lost their mother and father,” Baer said.
The lawsuit alleges an over-pressurized line of Penneco Oil Company had a leak of more than two and a half inches and was leaking 156 cubic feet of gas per hour before the explosion.
Penneco Oil Company chief operations officer Ben Wallace shared this statement: “We have not been served with a complaint nor have we reviewed it yet, however Penneco denies any responsibility for this unfortunate tragedy.”
“We know that the pressure on the line with the leak had continued to increase in the months and weeks and days leading up to the explosion. We know that gas was migrating from the leak and that the Oravitz home was full. The basement specifically was full of gas at the time of the explosion,” Baer said.
The basement is where the Oravitz family’s water heater, allegedly made by the defendant A.O. Smith Water Heaters, was stored.
The lawsuit claims a noise coming from the water heater the morning of Aug. 12 is why friends and neighbors Michael Thomas, Kevin Sebunia, and Casey and Keegan Clontz went to the Oravitz home.
Despite the gas being turned off, the lawsuit says the noises continued. It claims A.O. Smith Water Heaters informs customers that the noises indicate proper functioning and fails to warn them that the noises can be triggered by external fuel sources.
The lawsuits list several other defendants, including Peoples Gas, which it alleges failed to repair a failing regulator and take responsible actions to prevent the explosion.
“When this event occurred, Peoples immediately worked with the authorities to assist in the investigation to determine what happened. It is important to note that the Pennsylvania Public Utility Commission conducted an extensive investigation, and at the conclusion of the investigation found no evidence linking Peoples’ public utility infrastructure to the cause of the incident,” Peoples Gas said in a statement.
