MANASSAS, Va. (WUSA9) -- Firefighters experienced a close call when crews rushed to an apartment building in Manassas on Monday at 10:57 p.m. At first, firefighters tried to douse the flames from inside the building in the 11200 block of Lady Jane Loop, but part of the third floor roof collapsed on their heads. They were wearing protective equipment, according to officials.
The firefighters sent a Mayday signal, but all managed to evacuate the building.
One resident was sent to the hospital, say fire officials. Two firefighters were taken to a hospital for observation and two others sustained minor injuries, according to officials.
Fire department officials say two apartments were affected by the fire. Twenty units were leased in the building, meaning approximately 60 residents have been displaced as a result of the fire, according to officials. Red Cross and Bozzuto Property Management helped people check in to hotels, according to a fire department spokesperson.
Two buildings were declared unsafe, with the preliminary damage estimate is $500,000, say fire officials.
An investigation into the cause of the fire is underway but at this point, investigators believe it started on the third floor and spread to the attic.
