Thanks for all the input guys. It has been interesting so far. However I want to clear up some misconceptions.
First as for my instructors at FDIC this year of the 20+ only 4 were from FDNY the rest were from California, Massachusets, Ohio, Indiana, Texas, Florida and others. So it isn't just the FDNY show.
The tactics we trained in were for two man teams basicly. Most of the instructors depts had staffing on Trucks of 4 or less. (one in fact had a two man truck augmented by a 2 man ambulance)
Paul Thanks for bringing up the booster line issue. That is what my dept did take with them in years past, however as with many depts here in the states the Booster line is being left off of new trucks and is not allowed for fire attack. (seperate issue for seperate time)
As for experince and big cities are the only ones that should attempt this...I have to respectfully disagree. I am in a large suburb of a metropoltian city so my view point might be different from yours. But I have many friends in "big city" depts. Some run alot as suggested. Others run less than I do! If running frequent fires determines whether you are able to search without a line...then wouldn't that also preclude you from entering the burning structures to begin with because you don't see enoguh fire to be on the attack line. And one instructors Dept was comprised of 2 engines 1 ladder and 1 ambulance. That is it. Not very big to me.
As I said in my original post, as I see it small responses will affect the search decsion but from my point of view we are the fire department and we get paid to do certian things. Once the first line is in operation the next task that will save the most lives according to those that are in the know is to perform a rapid primary search without a line. If my family were stuck in a fire I think the benefit of going in without a line greatly outweights the risks. After all we are supposed to be the profesionals and no one else is going to do our job. We always train to keep up on our skills so we should know how to properly perform at the real deal.
Thanks for all the replies, keep them comming!
