A short time later, the house exploded and burst into flames, with multiple mayday calls coming from the firefighters trapped inside. Crews rushed in to try to rescue them from the debris that covered them, but one firefighter was killed and nine others were injured, Loudoun County Fire and Rescue officials said in a news release. Authorities did not say if they believe the propane tank leak caused the explosion. After firefighters found the leak in the underground propane tank, they requested a hazardous materials response team and additional units and safety officers. “This is believed to be an isolated incident and there is no ongoing danger to the community,” Loudoun County Fire and Rescue said in a statement.
