Straghit Stream -v- Fog Nozzle

[RescuHoppy7]

Ok First of all I'm not trying to spark a great debate, I was just curious as to what everyone uses on their engines for the attack line, were trying to convince everyone to put the straghit stream nozzle on the attack lines...Stay Safe!

Okay this has been discussed, debated, and been a debacle here more times than I can count.

First of all some semantics. A straight stream can be made with a fog nozzle, a solid stream is made with a smoothbore nozzle.

My volly FD uses break apart nozzles with a 200 gpm at 75 psi combo tip with a 1 1/4" slug tip behind that.

All nozzles are putting out fire somewhere. While I prefer the smoothbore our set up is a compromise that I can live with. Our firefighters are trained to use the straight stream on the combo when doing interior fire attack.

First the hose size and intended use, then the nozzle and tip.

1inch..... Brush line. 1" breakaway W/combi tip

1.5 inch.... Fire Attack Line. 1.5 Breakaway w/combi tip.

2inch..... Backup Attack Line. 1.5 Breakaway W/Solidbore Tip (1.125")

3inch..... Holy Cow Line. 2.5 Quarter Turn Gate Valve W/ 2inch Solidbore Tip.

Works for us......

Our situation here is a bit different than most in that we are operating in an petrochemical facility. All fire fighters are taught to open up on full fog and adjust down to power cone or straight stream depending on approach. Straight stream to throw cooling water to adjacent vessels or lines, power cone or full fog to approach for vale isolation. All lines are 2 1/2" running at 14 bar ( about 200psi) with adjustable flow and pattern nozzles. All fire boxes also carry inline foam eductor with aspirating nozzle.

Fyreup....you can do the smae with one manufacturer's dual pressure nozzle... In the low pressure setting you can develope a SB stream...I have seen it and pitot'd it.

In answer to the question, we carry the Elkhart Chief (not my choice) on 1.75" lines and we also have a couple old akrons and tft's. On our 2.5" lines we carry on old fog with a playpipe (again....not my choice) and the other with a SB and Playpipe.

all 1 3/4 hose has combination nozzles
all 2 1/2 hose has smooth bore nozzles
again try SEARCH before posting

This topic should be coded the Lazarus thread"...it keeps coming back from the dead!

It won't matter what you use, what it flows or the hose size, fires always seem to go out.

[hwoods]

Would it be easier on everyone if we had one thread for discussing those things that just refuse to die?? We could call it the "What size hose and nozzle should I attach to the lightbar on my POV that I use to go to the station to get a Beer??" Thread. Stay Safe....

it's just one tool in the toolbox.

I found your post interesting. I used to work at a petrochemical facility. I have a few questions. I am interested in the differences in your operations and how I was taught to perform valve isolation, adjacent vessel cooling, etc.

Why use such big lines at such pressures? I have isolated many valves with 1 3/4 inch lines.

When using the big lines to cool adjacent vessels, lines, etc., a straight stream seems to waste a lot of potential cooling water because it slaps the tank and then splashes away. We were taught to open the stream up so that the water hit the target and flowed down across the surface in order use all available water, and to cool a larger area.

captstanm!...

You absolutely cannot make a solid stream with a fog nozzle irregardless of whose it is. The deflection of the stream around the stem makes it impossible for the stream to leave the nozzle as a solid stream. It may come back together and form a wonderful straight stream, that may or may not be accurately pitoted, but it will never be a solid stream.

And having seen that wonderful dual force nozzle gain 1 gpm when switched from regular to emergency low flow in a simulated standpipe set-up I whole heartedly agree they are worth every penny....NOT.

By the way, how long have you been selling TFT's?

Nah...it would have to DIE, first.

[hwoods]

Could it be that the young folks have never seen a Santa Rosa nozzle, or that Akron creation that had a 1 1/8 tip with a fog cone around it?? For those of you who weren't there, the period 1945 thru 1965 saw a lot of experiments and research in Nozzle design. Some are with us today, others fell flat, a few were spectacular failures, but at least, people were challenging the status quo in water application equipment and techniques. Many of our solid, dependable, tools of today came from that era. Stay Safe....

We've still got a couple of these around! Got a 2-1/2" fog nozzle TWIST-ON!!! Talk about a bugger to operate! It looks much better in a display cabinet than on a preconnect, thats fer sure!

[FyredUp]

hwoods...

I am aware of those nozzles, but I would hardly put those in the same class as a regular combination nozzle. There is quite a difference between a combo nozzle with a smoothbore integrated into it and a combo nozzle with a stem that the water has to flow around.

I still stand by my prior statement that no combination nozzle can make a solid stream.

Here we go again..........


DING DING!!


Round 1..............

[RescuHoppy7]

OK First things First I didn't mean to dig this thread up from the dead, From everyones tone it's sounds like I'm beating the dead horse but I'm only looking for opinions as to what works/what doesn't work for a Smoothbore 1 3/4 attack lines! If I wanted sarcasm I would have asked nicely for it! Not that we have that out of the way I was curious if anyone has a picture of a Hi-Pressure Nozzle it would help too!...Stay Safe

And that's why people were saying to use the "search" function of the forums. You will find multiple threads in this same topic and none of them are different.......... They all end up the same way. You have some people that swear by smooth bores and others who will only use combinations. Each nozzle may work better or worse depending on the situation. Just do us a favor and at least look through the other forums on this subject, because it looks like it's already starting to get ugly in here.......
