Basement/Cellar Attack Line Size
In drawing up a training class outline, the question has come to me regarding size of attack line for residential basement/cellar fires. I've heard alot of the theories about this but am looking for some input relative to specifically residential situations. Would you be more inclined to identify a minimum flow requirment or do some of you subscribe more to the size of the line theory? Is 250 GPM on a deuce and a half a bit much for a residential fire situation? Would 180 on a 1 3/4" be acceptable? I expect alot of opinions to come of this, but please give me some good arguable and sound material to work with.
Thanks in advance
