The Fire Department has helped workers at One World Trade Center put out a small fire on the 89th Floor. Apparently some wooden decking caught fire.

WCBS 2 reports, "The Fire Department said it got the call for help at 7:15 a.m. Workers at the unfinished tower extinguished most of the burning wood themselves, but firefighters were still on the scene wetting down the area an hour later. The floor has been charred by the flames and smoke could be seen for miles, the FDNY said. Construction has been halted at the site until the FDNY figures out what caused the blaze."

On April 30, 1 World Trade Center officially became the tallest building in the city. It's unclear if it'll be the tallest in the country.

Update 4:42 p.m.: One firefighter was reportedly hurt while fighting the blaze, suffering minor injuries.
