House fire in Darnestown (Montgomery County Fire and Rescue)

Montgomery County Fire and Rescue officials said a house fire in Darnestown on Thursday nightmay have accidentally started after contractors working on a deck improperly discarded oily rags and paint brushes in a plastic bag.

The blaze, which started at 10:30 p.m. at the home in the 15100 block of Rollinmeade Drive, caused a family of six people — two adults and four children — to be displaced. There were no reported injuries.

The fire caused $1.5 million in damage, including $1 million to the structure of the house and $500,000 worth of damage to the contents of the home, according to fire officials.

The fire started in the shed and spread to the deck and house, fire officials said. The oily rags and paint brushes caused a “spontaneous combustion,” fire officials wrote in a tweet.

The incident follows a fatal fire that happened Thursday in Germantown. A Montgomery County detective rescued a woman from the house fire, but her husband died in the blaze. Officials said they believe that fire started on the second floor, but the cause remains under investigation.
