2″ vs 2-1/2″ Hose/Nozzle Comparison - Brass Tacks & Hard Facts (Episode 12)

In this episode, Jeff Shupe compares in detail 2" versus 2-1/2" with a side-by-side comparison showing that while the 2" hose line has its applications, the 2-1/2" is still the "King of hose lines".

I've been "retired" from the fire service (volunteer) more than fifteen years now. I've never seen a demonstration of how a straight-tip nozzle could be utilized as an attack line. We were always--religiously-- taught to rely on nothing but a fog nozzle. But then I realized that this was what old "leatherlung" firemen used before MY time! Geeeez! Makes me wish I was twenty-five again back on Fremont Rural Fire Department (Nebraska) so I could practice this stuff. Old dogs, man. Old dogs...

Great Videos

[@kcender3771]

Nice video.

[@jean6061]

Interesting. I never knew why it took more than one firefighter to handle the hose. Thank you.

[@medic2807]

With the current materials that are encountered in the average residential fire, 2' should be an option for every fire.

Shupe was a great guy. I sure miss him.😂

Wouldn’t you run a risk of steam burn by bailing the gate down as you advance? I would think you should close it completely if it’s really hot. Seems like a 30 degree power cone to me. Not saying it’s wrong just asking because from what I read not from my experience. Not fires I have been in were not that hot.

[@pyroman6000]

You might increase steam production some, but if you look carefully, the droplets of water produced are much larger than a fog nozzle creates. So they won't flash to steam as rapidly- it'll be like you're bouncing the stream off the walls and ceiling. Or, to use the presenter's analogy, like a sprinkler head. This is just a quick, short duration tactic to help when you want to move in a bit to get a better shot at the fire. Done AFTER you've knocked down what you can from your present position.

[@jeffcrawford5222]

Closing it would cause the line to stiffen up keep the forward air pressure and soften the line so you can move. The only thing I see wrong is the nozzle man needs to move with both the right leg and left arm in the ground right arm hugging hose slightly pushing back on back up man the back up man makes the push when commanded from the low stance.

[@Striker51z]

Not really. Structural gear is going to have a moisture barrier in it to prevent this. If you're wearing you PPE right, it shouldn't really be an issue. Do note that if you do have any skin showing and blast a room with a wide fog pattern, you WILL be made aware of it.

[@Buttsizzle]

If it is that hot and you’re advancing without flowing, you should consider using the reach and penetration of your fire stream to cool the environment you’re in as well as in front of you, or flowing full bore as you make the push. Recent data from experimentation by the UL show that smooth bore streams more effectively penetrate the thermal layers and cool down the entire space from the top down without creating as much steam in the lower occupied spaces via penetration and water mapping. As @pyroman6000 said, with fog patterns, the already broken-up droplets are quickly converted to steam before even reaching the hottest top thermal layer and cause much more steam production closer to the floor.

255 gallons per minute?!!! Holy crap!!!

Try using high pressure hose reels on wider setting and pulse. It uses less water and is just as effective. Wider pattern on high pressure hosereels create larger surface area because of droplet size so the water is absorbed better and is more effective at reducing heat.. Spraying the whole room with it running down the walls just wastes the water.

[@lucasnadeau2376]

You like using a pressure washer to put out fires? Lol

[@andyoxleyonhistravels]

@@lucasnadeau2376 You obviously have no modern understanding of different methods then fella ?

[@lucasnadeau2376]

@@andyoxleyonhistravels a simple room and contents or a grass fire, yeah a UHP system will get the job done. But try fighting more than a single room fire with UHP. Won't work. I'm not a fan of all NFPA's but there's a reason they call for at least 300gpm between the first two attack lines pulled. I'll take my chances with an 1 1/2" hose any day before using a UHP attack.

[@andyoxleyonhistravels]

@@lucasnadeau2376 UHP is far quicker, uses less Water and lighter so you can move faster. Much better if you are looking for victims. Stop living in the past. We've been using high pressure hosereels for the last 25 years for pretty much 90% of all structure fires and they work extremely well. Uhp works very well on much more than a single room fire. The video evidence is on here to prove it. It's very simple really, uhp equals larger surface area which is absorbed better which reduces heat quicker which in turn knocks the fire back quicker and combined with the fact its lighter increases your speed of movement. Simple really.

[@andyoxleyonhistravels]

@@williamvanbrimmer3493 What's wrong about it then ?

[@smilernok]

how many men does it take to handle the hose for filling up an airbus 😃

[@whynotjustmyusername]

60 psi? In Germany we work with at least double the pressure.

[@coltjones6819]

Def7355608 on Smoothbore?

[@whynotjustmyusername]

Sorry, both of you, I didn't notice your replies. In Germany we do not use simple smoothbore nozzles at all (and have not for about a century). The classic standard nozzle is the Mehrzweckstrahlrohr (multi purpose nozzle), which can be switched between a straight stream and a spray. They have removable muzzle tips (without those, only straight stream is possible). (de.wikipedia.org/wiki/Mehrzweckstrahlrohr) However, since a few years they are no longer to be used in internal attacks. For those, we use fog nozzles only.

[@whynotjustmyusername]

You are right, I was only thinking of pump pressure, which in Germany is 10 bar (145 psi) (historically 8 bar (120 psi)). The rule of thumb pressure on an open nozzle is 6 bar (90 psi), which is still 1,5 times higher than the US standard, however, given the usual setup of an attack (pump-a few 2,5'' lines, distributor, a few 2'' lines) it can be higher than that. Usually the precise pressure is only of concern when using medium expansion foam nozzles. HOWEVER we use far smaller flowrates. The traditional attack consists of two CM (2'' coupling) nozzles without tip (12 mm) at 200 l/min (50 gpm) and one BM nozzle (3'') with tip (16mm) at 400 l/min (100 gpm). The entire attack uses less water than one nozzle shown above. I intentionally said traditional here, as mentioned earlier Mehrzweckstrahlrohre are falling out of use. Usual preset fog nozzle flowrates are 130 l/min (35 gpm), 235 l/min (60 gpm) or 400 l/min (100 gpm) at 6 bar.

[@cadenwebb7600]

This pressure is at the tip

[@whynotjustmyusername]

Yes and as nozzle pressure we use 6 bar instead of 4. Often times we'll go even slightly higher. Some departments routinely work with a nozzle pressure of 8 bar.
