Investigation Concludes: Propane Leak Cause of Fatal Home Explosion in Loudoun County

Investigators announced on Friday that they have completed their on-site investigation into the home explosion in Loudoun County, which claimed the life of one firefighter and injured many others. The Loudoun County Fire and Rescue’s Fire Marshal’s Office has determined that the explosion, which occurred last Friday at 347 Silver Ridge Dr. in Sterling, was caused by a leaking 500-gallon underground propane tank.

Officials stated that the propane leaked into and around the house, ultimately igniting and causing the explosion. However, investigators remain uncertain about the source of ignition. In total, 14 people were injured by the blast, tragically including Sterling Volunteer Firefighter Trevor Brown, who lost his life in the incident.

One firefighter remains hospitalized but is in stable condition at the Burn Center at MedStar Washington Hospital. The explosion caused damage to six residences, with three of them deemed unsafe for habitation, prompting residents to evacuate.
