    Question smooth bore vs combo nozzle studies

    I know this has been talk about to death, but im only interested in actual studies either done by fire departments or organation like colleges. My dept has grant money to buy new eqiupment to replace 30 yrs equipment and the chief would like information about the scientic aspects of both nozzles and thier effects on fire extingishment. Can anyone direct me to links either on here, on web, or publications that have infomation on actual studies. Thank for you help. and thank for not turning this into a repeat of personal opinions. If your own dept did a factual study please that information would be very helpful to.

    I'd be interested in seeing some studies as well. We're an all combo department, but I wouldn't mind seeing some more info.

    If you go to some of the nozzle manufacturers sites, you will see they have some studies published. Of course, magically, their brand will come out on top. But at least it's something to compare.

    The Rockland County, NY Fire Training Center is home to a-lot of the most recent studies. Started by the Late Andy Fredricks, Sq-18 FDNY and carried on by by the members of the Training Staff. They have done numerous articles for Fire Engineering and Firehouse Mags plus they have done the big Buff expos. I had all the info on a computer that crashed and burned.....sorry, but you can try to contact them directly.

    In either the Jan or Feb 2006 Fire Engineering Magizine had an article about a department in Florida that conducted their own study. After that study they decided to switch mostly back to smooth bores. You might want to look there. Sorry I can't be more specific.

    I'm a little concerned that your CHIEF needs information about the scientific aspects of both nozzles and their effects on fire extinguishment. IMHO, he should be throughly familiar with the advantages/disadvantages (including "scientific aspects") of both in order to hold that position.

    I also have found the late Andy Fredericks FDNY SQ-18 articles to be very informative. You can tell by reading them what passion he had for the job.

    Please don;t bash a chief that you don;t know. Our fire dept is in a very rural part of Akransas, we don;t have fomal training beyond the basics and often the chief is the person that shows up for most of the fires.

    I'm not bashing. At least he is asking for the information. Please don't take a principle of having the chief be the expert in the department as a personal attack on your chief.

    Hey Dave,

    I thought that you guys went to all break-apart nozzles. During a field test recently we were told that you guys had switched.

    We use Akron break aparts. Let's the nozzleman use what he wants.

    To a dept on Long Island, it doesnt matter smooth bore or fog. initial attack line (most times backup too) is a high pressure booster. They have done this for years, and swear by it. I'll pass on this one.

    So much of it just plain comes down to your department's attack style. If you're an aggressive department, you're gonna go for the versatility of the combo. If you're a less aggressive, more defensive department, the longer reach and harder hitting of a smoothbore will serve you well.

    That is completely untrue. I would venture to say that the FDNY is one of the most aggressive depts in the entire world. (If you want to debate that, fine, but Im not interested). The only fog nozzles we have are on our front bumper lines, for car fires, trash fires, etc. Everything else is smoothbore. I'm not sure where you got this information about aggressiveness, but it is simply not true.

    And being aggressive with a combo nozzle is just going to get you steam burned.
    I don't recall putting a definitive in that statement anywhere.

    If I'm going to be making an aggressive attack, I personally (along with many in my department) would much prefer the versatility of a combo nozzle. As to being aggressive with a combo nozzle and getting steam burns - sure, it can happen. But if I recall, combo nozzles aren't locked to fog. :-\

    Sounds pretty definitive to me.
