Baltimore, MD – WJZ-13 – A Baltimore fire spokesman says it’s a blessing no one was killed when a Park Heights home exploded this morning.

Fire officials are investigating the cause of the explosion, which leveled a home in the 37-hundred block of Boarman Avenue.

Fire spokesman James Gardner says an active gas line was ruptured, but it’s not clear if that was the cause of the explosion or happened as a result.

BGE shut off the gas line this afternoon.

Neighbors say a resident and another man were working on a water heater when they began to smell gas.

They got outside before the house exploded, but each was injured.

Authorities say the injured men are 67 and 61 years old.

They suffered burns to their hands, arms and faces and were taken to the burn center at Johns Hopkins Bayview.

A woman who lives in the home was inside at the time of the explosion, but got out safely.

She says she climbed out her kitchen window.
