Getting Back to Basics: Nozzles & Hose Streams
I would like to start this off by looking at this picture and what I would like for everyone to do is tell me everything you see on what is being done wrong or right and what is missing and needs to be added. And as we go along we will get into Different types of nozzles some that are old and some that are new, and if anyone has some insight for the rookies in here please share. Remember Knowledge is power, and with that knowledge it keeps you and everyone else safe.

Something to add can anyone tell me the three elements essential to combustion or the beast we fight, and what I mean by the beast is fire???? What does it take to make fire???? And what happens when we use water to remove one of those elements?

Some may ask this is getting into fire behavior, but it is a critical part of useing the right tool for the right job. And what that means is useing the right nozzle for what you have at hand...Something to thank about...

#1 Back up man there isnt taking any wieght of the hose.
#2 Where are the scba's (I know that was already said thats why its #2)
#3 Why do you need to be that close? Judging by the smoke Its wood burning that was started by petroleum. So wouldnt you want to move around to the right past what looks like curbing.
I know im a newbie and I dont know much. But, I thought If I put my 2 cents in and im wrong I can learn from it.

Overlooking the obvious, it doesn't appear they have enough water flow either due to the nozzle gated down, an incorrect gpm setting, or a pressure issue from the pumper. This coupled with using a modified cone pattern means they are not getting penetration to break the chemical chain reaction.

Good job Loyd here is a picture to go along with that back-up man

Is it possible that this exercise is taking place in a flammable pool type scenario? There sweeping the fire away (dont know the accuall term) and that is the reason they have the nozzle so low and the back up man is so far away?

Lets note that both fireman are on the same side of the hose...Look at the back-up man with his body weight forced forward to help the strain on the nozzle man...In most cases you act as one...

fuel. . .heat. . . and Oxygen to get combustion. . . add chemical chain reaction to get fire

Here is a picture that some use this technique to teach and as you can see in a stationary position a backward facing back-up man is putting his whole back against the nozzle man with total support. And with this both directions are being watched including where the water is going and where the water is coming from and any and all conditions around them.
