Update: Broken Furnace Pipe Caused Carbon Monoxide Leak, Poisoning 10

WOODBRIDGE, VA — Investigators have determined what caused a carbon monoxide leak at a Woodbridge home on Tuesday, the Prince William County Department of Fire and Rescue said.

10 people, five adults and five children, were hospitalized with carbon monoxide poisoning. Authorities did not provide any update on their condition.

Building officials said the carbon monoxide escaped from a broken furnace pipe in the basement.

"All homeowners are strongly encouraged to have their gas appliances regularly inspected by a trained professional," fire and rescue officials said in a news release.

Around 10 a.m. on Tuesday , first responders were called to the 2400 block Neabsco Creek Court for an inside gas leak.

"Crews arrived on the scene to find 10 individuals feeling various degrees of sickness. Based on the situation presented crews began to take air readings," fire and rescue officials said. "It was determined the air within the home contained high levels of carbon monoxide. All of the individuals were removed from the structure."

Responders from Washington Gas secured the building, according to authorities.

In a news release, authorities urged residents to take precautions to prevent carbon monoxide poisoning. All homes should be equipped with carbon monoxide detectors, according to the Prince William County Fire Marshal’s Office.

"All gas fired appliances and furnaces need regular inspection for proper operation. Fireplaces need to be inspected for proper operation and ventilation. Do not operate a generator inside your home or garage," fire and rescue officials said. ""Be familiar with all appliance operating instructions, as many appliances require varying degrees of ventilation to operate safely. Kerosene heaters often require outside ventilation."
