There were no injuries in a fire in a high-rise office building near Dulles Airport on Tuesday, which started in a first-floor “battery room,” according to the Fairfax County Fire & Rescue Department. A security guard in the 10-story building called 911 after hearing an explosion.
Arriving on the scene at about 7:45 p.m., firefighters and rescue personnel found an electrical transformer on fire outside the building, the fire department said.
The building at 13820 Sunrise Valley Drive is the headquarters of Time-Warner, according to media reports. It is just south of the interchange of Route 28 and the Dulles Toll Road near Herndon.
The firefighters also encountered heavy smoke coming from the lower level of the building, with flames coming from the battery room.
The incident commander sounded a second alarm, bringing more than 60 firefighters to the scene, the fire department said. There were about 50 employees in the building when the fire broke out, and the firefighters ensured all occupants got out.
The firefighters contained the blaze to the battery room and the transformer; it didn’t spread to other parts of the building, the fire department said. The building’s automatic fire alarm activated, as well as one sprinkler head, which helped contain the blaze.
The fire department estimated that damage to the building totals $2 million. According to fire investigators, the blaze was accidental. They traced the cause to an “electrical event” in the control module of the building’s power supply.
Lightning may have started a small fire Friday in a northwest suburban medical office building, where an internal sprinkler system doused the flames before firefighters arrived. Elgin firefighters were called just before 7 a.m. Friday to the medical building at 1015 Summit St. after an employee arriving for work called to report a fire alarm going off, according to a statement from the Elgin Fire Department.
Firefighters heard a strobe horn going off, and saw water flowing out from an exterior door, but saw no smoke or flames. When the door was forced open, firefighters found that a fire had started in the telecommunications equipment and activated the sprinkler above. Investigators determined the cause of the blaze was “either an electrical issue or a lightning strike,” which caused the telecommunications equipment to catch fire until it grew strong enough to set off the sprinkler.
The alarm signal directly into the fire department did not activate because it is the telecommunications equipment that activates it, according to the department, which recommended a wireless system be installed. Fire and smoke damage to the building and contents was minimal, but the “building was determined to be unsafe due to an inoperative alarm, inactive sprinkler system, and unknown electrical conditions’ and consequently red-tagged,” the department said. City Code Enforcement inspectors were notified. No injuries were reported.
