Authorities said neighbors were the first to respond to the explosion after hearing a loud boom and seeing smoke emitting from the man's garage. They were able to provide "basic medical care until first responders arrived" on the scene.

Suffering from severe injuries, the man was taken to a Baltimore trauma center via a Maryland State Police helicopter. He remains in serious medical condition, according to the fire department.

No other injuries were reported at the home, although investigators did indicate the detached shed sustained significant structural damage.

The incident remains under investigation.
