Sandy Springs, GA- Building inspectors Tuesday were examining a Sandy Springs apartment building rocked by an explosion to determine whether any part of the building is inhabitable. A resident of the complex described the blast as like something out of a Hollywood movie.

The Monday afternoon explosion, which left one resident with burns on his face and neck, was believed to be caused by gas, Sandy Springs police said.

“The preliminary determination is natural gas,” police spokesman Lt. Steve Rose told the AJC.

Fire investigators continue to look into what specifically caused the explosion, however.

The explosion occurred about 12:30 p.m. in a first-floor unit at the Edgewater at Sandy Springs apartments, in the 7600 block of Roswell Road. According to police, “the front wall of the apartment was blown into the parking lot as a result of the blast.”

Sandy Springs Fire Marshal Jeff Scarbrough told the AJC it could take days, or even weeks, before authorities complete the investigation into the blast, which he said was “pretty forceful.”

The explosion blew debris about 200 feet and imbedded glass into a tree, Scarbrough said.

Resident Alberto Reyes said he was in bed, watching TV when “I heard and felt the building shake.

“It was scary,” Reyes told the AJC on Tuesday. “It’s something you don’t see in real life. It was like a movie, a Die Hard movie.”

Neighbors reported smelling gas before the explosion, Rose said.

The victim, who is in his 30s, was taken to Grady Memorial Hospital. His condition was not immediately available.

Neighbors told WSB-TV that the man had just moved into the complex.

No one else was hurt.

“Our inspectors are on-site,” Nancy Leathers, director of community development for Sandy Springs, told the AJC late Tuesday morning. “However, we may not be able to make a final determination on all of the building until it is examined by a structural engineer.”
