We were on scene ahead of our engines, and there was a victim trapped inside. With two water cans filled with FireIce, I started towards the building. My chief and another fireman had tried twice to get to the victim's bedroom, which was maybe 15 feet in to our left, but got pushed out both times. I was ordered to stay at the door and not to try again because it was too dangerous. So I sat there and did what I could. Remembering I had FireIce, I coated the bedroom door and also sent some down the hall trying to coat anything that I could so that I could make room. Surprisingly, I made it (through the hall) and was able to enter and start locating our occupant. With one can empty, I used the last one sparingly, covering what I could, searching a little, covering some more, and trying to cool down the ceiling as much as possible. I grabbed a member off the line, and we searched the room again. My partner found our occupant, and we removed her from the room, passing her to our brothers to get her out. After the many times using FireIce, and after what I saw when I went back in to look at where we were fighting, I am sure that the FireIce I was using bought me valuable time where water alone would not have. It still amazes me that even in a fire as hot as this one, you could make out exactly where I was hitting the walls and ceiling with the product, almost as if I went in with a marker and marked where my stream hit.
