By your screen name I will post this with the assumption your are a Fire Fighter. I have been on many, many structure fires. Modular, Stick, Trailer ect. It would be a cold cold day before I had a live fire unit in a modular. If anything get's into the very small voids spaces that fuckers will run like crazy. It's very hard to stop.
To be fair, I am a bit paranoid. When I looked for a house one of my requirements were that it did not have an attached garage. When I build a garage, it will not be attached.
In bed, according to prophesy.
