When evaluating nozzles for use with CAFS, there are four criteria that affect firefighter safety and firefighting efficiency. These are target delivery rate, finished foam quality, stream reach, and nozzle reaction force. Before we discuss each of these, let’s quickly discuss the use of Class A foam with a compressed air foam system. Class A […]
Most firefighters are familiar with nozzle aspirated foam systems (NAFS) and how they deliver foam to the fire. Another method of foam delivery is the compressed air foam system (CAFS). The following is a brief introduction to CAFS and how they work. Compressed Air Foam Systems (CAFS) With a CAFS apparatus, there is no need […]
Right tool, right job. Combination nozzles and fog patterns are not right for every situation. This story is an example of when it works. “What am I going to tell his mother?” Bill and Rhett Wallace responded to a mutual aid call for a neighboring department. On scene, the father and son found themselves on different […]
The MID-FORCE Nozzle is an automatic flow, dual pressure fire nozzle with a switch on the baffle that moves it from red mode to blue mode. In this video, Brian “Pods” Podsiadlik explains what this switch does, what red and blue means, and gives examples of when you might use each mode. What is the […]
Automatic nozzles are a relatively new technology to the firefighting scene, compared to traditional fixed flow or selectable nozzles. You’ve probably heard at least one of the following about automatic nozzles… “You can’t tell what you’re flowing, if you’re using an automatic nozzle.” “Automatic nozzles need calibrated and it’s a PITA to make sure they’re […]
It is no secret that you can encounter flow issues and increased reaction force when you shut down a line during gated wye operations. So, how can you limit flow issues with this setup? Working Fire Fixed Flow Nozzle with Pressure Relief The Working Fire nozzle is unique due to its pressure relief feature. This […]
The Working Fire 150@75 Fixed Flow nozzle with Pressure Relief is available with a color-coded bail handle & a color-coded straight stream indicator ring on the bumper of the nozzle, & features a wide open space on the top for laser engraving of your dept. logo. TFT was the first company to pioneer customized […]
Have you ever unintentionally moved your nozzle out of straight stream? The Working Fire nozzle helps you stay in straight stream and pack your gear away however you want. Standard Straight Stream Indicator Ring and Detent Every Working Fire nozzle is built standard with a straight stream indicator ring. This allows you to […]
https://vimeo.com/manage/videos/428540969 The Working Fire Fixed Flow nozzle with pressure relief is built standard with a 1-3/8” diameter stainless steel ball valve and a field-replaceable valve seat. These two elements bring quality and simplicity to the nozzle while it helps you manage nozzle reaction during moments of increased GPM. Stainless Steel Ball Valve The standard stainless […]
The Working Fire nozzle is an exclusive design that delivers optimal GPM with minimal reaction force. Fixed Flow with Pressure Relief The Working Fire Nozzle is a fixed flow firefighting nozzle with pressure relief. This takes fixed flow to a new level. The 150 at 75 nozzle delivers the flow you expect […]
In the fire service, it is often believed that a smoothbore has the highest impact force or that it is the hardest hitting nozzle. You may love a good smooth bore, but did you know that impact force doesn’t actually depend on the type of nozzle? Which Firefighting Nozzle Has the Highest Impact Force? […]
What is a Ball Valve? A ball valve is a valve that allows you to control the water through your firefighting nozzle. It is designed to be used fully open or fully closed, though some firefighters will gate the valve, or close it part way, to create turbulence and break their stream. What is a Slide […]
With hundreds of models of handheld fire hose nozzles from which to choose, the choice can be confusing and the decision making process often frustrating. Before investigating which nozzle may be an ideal choice for initial attack fire flow operations, one basic factor must be considered before all others: Determining the agency’s target fire flow will be critical to the overall […]
Sketched on a napkin in 1968, the automatic fire nozzle is the youngest nozzle type you’ll encounter in the fire service. So, how do they work and what makes them “automatic?” Let’s find out! What is an Automatic Firefighting Nozzle? An automatic nozzle is a variable flow, constant pressure firefighting nozzle. This means that […]
How Does a Selectable Firefighting Nozzle Work? A selectable nozzle allows you to change your flow rate on the fire ground without changing tips. In this video, you will learn more about how these nozzles work, how they relate to smooth bore tip sizes, and what happens if you change your GPM selection without communicating with […]
