During a hose and nozzle demonstration, you have one goal: find the right solution for your fire department. You can expect your sales rep to guide you through the selection process with expert insight and advice. Everyone will conduct their demonstration a little bit differently, but in general, they should all start with the nozzle. […]
“Is a water flow meter really necessary?” It’s a good question. If you’re wondering why you need a water flow meter, how you can use one, or how they can be a tool for you when training and testing equipment, this article is for you. Here are three reasons you need a flow meter at […]
What is an Automatic Nozzle? An automatic firefighting nozzle is a variable flow, constant pressure nozzle capable of building a set amount of pressure within its flow range. The nozzle does this with a spring-loaded baffle that automatically alters the opening size at the exit of the nozzle. This allows it to build the appropriate […]
Are you considering foam eductors but wondering how to choose the right size and type for your crew? Let Brian “Pods” Podsiadlik walk you through a few considerations before you decide. What Should You Consider when Choosing a Foam Eductor? When you select your eductor and starting using it, you should confirm four things: Your […]
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 […]
Firefighting foam plays a vital role in successful firefighting. Developed over a century ago to combat challenging oil fires resistant to water, this unique firefighting tool has evolved while retaining its core purpose.Today, it is still used to knock down and secure burning and unignited flammable liquids. Class A foams are also used on ordinary […]
As you switch over to SFFF formulations, you face a few different challenges. Have you explored them? One of the first major challenges you face is that SFFF chemical formulations can vary widely by manufacturer. Each manufacturer’s SFFF agent formulation may be significantly different from other producers, even proprietary. Think about that for a minute […]
Finished-foam quality — a measure of durability or usefulness of a foam blanket — is measured two ways; expansion ratio and 25% drain time. Finished-foam quality is a function of the volume of air drawn into the nozzle and the amount of mechanical agitation that occurs in the nozzle or nozzle-foam tube. Expansion ratio is […]
Do you even need a firefighting nozzle? Whether a rookie or a salty veteran of the fire service, it is safe to say 200 GPM is a heck of a flow rate that would put out a lot of fire if applied properly. This is no secret. If you dig into the majority of UL […]
Remembering all the variables that make up an efficient firefighting attack line can be difficult. In the fire service, you’re probably aware of and have learned about the foundation of Fire. The foundational principle of fire is commonly taught by using the Fire Tetrahedron. We’re going to go over the Fire Tetrahedron below. Then we […]
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? […]
It is often thought that the type of nozzle you use affects the reach of your water stream. This is not true. In this video, you will see that if the flow rate remains the same, the nozzle with the highest discharge pressure will reach the farthest. This is true across the different types of […]
