Five firefighters were sent to the hospital after battling an overnight house fire in Montgomery County.
The fire happened on Leekes Lot Way in Gaithersburg around 1:30 a.m.
There was a partial collapse of the roof of the home.
That prompted a mayday call for the firefighters to evacuate.
Five of them went to the hospital as a precaution but were not burned and did not suffer life threatening injuries.
The person living in the home got out safely.
