great explanation, got to have time on the nozzle to know what the pressure is. What is standard pressure and what happens in reduction and use the different nozzles. lots of reasons for kinks

A lot of FF are convinced with old suppositions. But the reach and penetration from a correctly trimmed straight stream from a fog nozzle has more of both, reach and penetration. Starting for pressures and velocity, 100 psi in fog nozzles against 50 or 80 psi in smoothbores at the same GPMs. But fog nozzles are more versatiles, you don´t need to close the water for changing tips, then looking for a place where store the tip, or looking for the tip for reinstalling because a lesser new flow. In selectable foggers you only rotate the ring, in auto nozzles with slide valve, the SAME on/off valve serves as GPM control.

I understand the notion that fog nozzles are more versatile, that is a very notable observation. But, in reality, a lot of what you just mentioned has been proven in numerous research studies to be misguided as "old supposition" itself. The reality is GPM is the single biggest determining factor when absorbing heat energy from a fire, and thus extinguishing it. Fog nozzles are available in lower pressures such as 50 and 75psi, however they are much heavier and when reduced to lower operating pressures a host of other issues occur such as nozzle whip. So, the vast majority of fog nozzles in operations are being operated at 100psi which causes a ton of issues. The selectable gallonage nozzle only works if the pump operator is communicated with to adjust the pressure feeding the nozzle. Same with the automatic. The bale itself will only "regulate" the amount of water given to it. The pump itself is what is delivering that flow to the nozzle. Without a substantial amount of communication these nozzles simply do not work as intended during real situations and real stress. This is most noted in the One Meridian Plaza fire which took the lives of three firefighters. A huge contributing factor of that fire was the use of automatic fog nozzles. Paul Grimwood of the London Fire Brigade discovered that the "average" firefighter can withstand and operate approximately 60 pounds of nozzle reaction... This is where things become significant. I personally conducted a nationally published research paper for the National Executive Fire Officer Program which showed that firefighters without very specific training lack the ability to "feel" their actual flow. In fact, over 50% of the test subjects did not detect a 25% reduction in flow from their nozzle when using the 100psi fog nozzle. This is because the higher pressure conceals issues that are difficult to detect. On the actual fireground we have seen demonstrated losses in pressure of around 10-15% as noted in Vestal and Bridge's research, "A Quantitative Approach to Selecting Nozzle Flow Rate and Stream - Part 1". This is a considerable drop in fireground flow that is typically completely ignored when "learning" about these topics in text books. Real world examples are abundant and have been demonstrated in numerous research projects. A lot of what you mentioned is accurate, however, a lot is also opinion and not backed with scientific research or data. We have an abundance of data which suggests the smoothbore is significantly better for interior structural fire attack. It is NOT better for the other varieties of fires, which you correctly mentioned the fog nozzle versatility. That being said, I appreciate the comment and discussion. Many of our firefighters need to understand these topics and very little information is shared in the text books regarding the significance of real world test results. Most of the classes taught, are taught in theory.

@@Boxalarmtraining Thanks for your response...I teach hands on using 1-1/2" 50-250 gpm Sho Flow flowmeters, I have two of that old spring loaded model. Both pitoted and give a very precise reading. The reaction force it´s very useful for "feeling" the actual discharged GPMs. When using smoothbore nozzles you have EXACTLY the very same problem about gpms as with traditional fog nozzles, being auto or manual, without comunication with the pump operator he hasn´t way for knowing how much or less pressure must pump, but with autos he/she only have to pump for a preselected pressure as 150 or 200 psi for a preconnect and the nozzle operator selects the flow he/she needs, all of this without the need of comunications...as you know, the first things to burn in a fire are the communications. Higher pressures conceal flow issues only in non automatic nozzles, a low flow opening selected, but with high pressure, if the FF didn´t see the selected gpm will fedback as it is flowing high GPMs, the same with smoothbores, but auto nozzles will have reaction force proportinal in straight line with the flow being discharged, in SBs or conventional (fixed/selectable GPM) fog nozzles, the reaction grows up EXPONENTIALLY with increase in pressure. Teaching the feeling of GPMs in auto nozzles itsn´t rocket science, it´s easy to learn and understand. Grimwood coming from UK fire service, considers 200 gpm a very high flow from a nozzle, but 250-300 gpm in straight stream can be controlled WITHOUT over exertion just seating over the hose, and higher flows, such as 400-500 gpm from 1-1/4" at 400 gpm at 80-90 psi, two FF seated behind the nozzle control it easily. For interior attack you didn´t need high flows, ususlly a 100 or less gpm will suffice. For exterior attack, you need stream capable of penetrating the flames, and still, after of travelling 20 or 40 ft, have enough "surviving" flow for absorbing the heath wich maintains the pyrolisis...not the flames heath.

Retired paramedic, volunteer FF here. I just came across this. Wondering what kind of wizardry this is? Or did the firefighters just use special fans to extract the flames? Still they’d have to get inside and kill the hot spots. Unless the city said, “fugit abuot it” 😂 I saw a fire break out once, near my office. It was an old factory where some junkies sometimes gather, so it naturally went up one day. There is a big heavy gate at the entrance of the yard with heavy steel bars and barbed wire. People from aroun the yard tried to open it before the firefighters came, so they had an easier job, but no one could open it, and there is a metalworking factory near it. Angle grinders, saws, nothing could cut it. The junkies used a small hole to get in. Haxomen: The firefighters came, took out some contraption and took the fire out through one of the windows of the factory. Using the Bernoulli principle. They never entered the yard. The fire raged 20 minutes and was done in 5 minutes after they came.

I (respectfully) COMPLETELY disagree with you on your training premise. I have worn MANY helmets in my life. Hockey, adventure, ballistic in military and police, hang gliders, motorcycles, USAF pilot training, etc… the fact that you train in a different helmet then the one you fight in is BS. Multiple evolutions? Yeah… they suck ass! I know. Trust me. But if you have to change the way you train vs. a real live event just to meet a mark set by the department then that says something about everything y’all are doing and someone is eventually going to get hurt. Train like you fight and you will fight like you have trained. There is simply no excuse otherwise. I was on the street as a patrol cop for almost 13 years in a major city. And I promise you that it was this mentality I credit as to why I and many others are still alive today. Train in one kit but expect to excel under pressure in a completely different kit???? Really???? You’re not a “professional athlete”. You aren’t playing a game. Real people expect you to save their real lives. This whole video just gives me the creeps

Good insight Matt. I do a lot of thinking on leadership. I think leadership, as a concept, is often done a disservice by not being given fertile soil in which to grow. Society has become fond of lamenting the death of effective leadership (we all do it) while seeming to only offer self-help-style leadership books and pseudo-empowering KZfaq videos and seminars as the solution. We are under the spell of these external "solutions" while, as you say, the answers are right there under our noses. I couldn't agree more. Good leadership comes from one thing: A good leadership culture. Without a culture that truly embraces (and expects) leadership from the very beginning of one's career, there will be no actual leadership--just a constant search, and a lot of badmouthing along the way. Anyway... Good video. Feel free to reach out if you ever want to chat.

Not quite. The 100-200 is just the GPM from whatever nozzle you are using. Once you know what your GPM is, you then use the corresponding muliplier and multiply by “12”. Hope that helps. That will give you the FL per 100’.
