This was a door in the simulator room, there was an electrical panel fire.  We went in in teams of 2, one person shut off the electricity then opened the door to the panel, and then the other person used a carbon dioxide extinguisher to knock down the fire.  The simulator was really neat, it was actually live fire, but there was a control room up at the top that could stop the fire in case something bad happened.  This was the third door, there was a trash fire and a flashover also.  On the trash and flashover fires, we got to use a hose to put it out, and on the electrical panel fire, we used a carbon dioxide extinguisher.
