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.

Here are a few types of Chimney nozzles for everyone to look over and thank about...Thanks Chief Dino...

One thing to always remember when selecting a nozzle to either use or standardize thought your department not one single nozzle will perform well under all conditions and flow rate is a critical factor in fire control, but a higher flow rate will not always provide more effective and efficient performance. Food for thought brothers and sisters...

To put as much of the wet stuff on the red stuff as possible...does it in one hell of a hurry too....some actually can be set up and left if the hazard deems necessary.....BUT don't ever set it at 90 degrees.....we actually stake and chain ours down when we use it.....Paul

Good note Ted...For the ones who use these types of appliances staking one down is very important and a huge safety factor for your scene...Thank you Sir...

Staking or tieing off is very important...

We also call them stingers, used for defensive operations, surround and drown. Great for getting a lot of water quickly into a building, easily makes the second floor and roof of a SFD and for commercialstrip mall operations. The have removable tips to increase the gpm's, I believe ours have 200, 400, 600 and 800 gpm tips, with all removed it's pushing 1000gmp. The smaller the tip the further it will shoot but with less gpm's. Ours are fed by 3" supply line.

Good pictures Doug, Job well done brother...Multipurpose nozzle...

Here are a couple nozzles for everyone to look at, one in a little different design and another with a straight stream and wide fog all in one...

I've read where if the wall/curtain is directly placed on the exposure they work much better. The type my department has is adjustable for that purpose. However, we've never used them in my 11 years. Like you said, a firefighter with a handline works much better.

For the ones who have never been involved in a live burn, notice in this picture how the firefighters advance toward the gas with a wide fog pattern.
