The gas pipe burst (it's between the exit & the window. The window is were our conference room is. We smelledsomething burning but ignored it. The fire alarm went off. We were trained to ignore it. Then someone from the floor above said that there was a real fire out. We we tried to exit the nearest one had huge flames. The firemen showed up in 5 mins. They kept hosing water fro 1hr. Then a lazy NW Natural gas person showed up (after an hr) and took him 15mins to shut off the mains. You can see fire blowing in one of these videos.
