At Fire Protection Online, we stock a wide range of firefighting equipment, including that which is used by the brigade. This is where our Fire Hose Nozzles take centre stage. We have a good range of hose types straight from our own brand, Vigil Products. This range includes Jet Spray, Lever-Operated, DO9 Long Pattern and the illustrious Selectable Fire Nozzles.
Nozzles and branchpipes are what give the fire brigade control over reach, flow, and area coverage. They are essential in creating a reliable system for directing the water supply. This is why it’s important to be aware of their uses, limitations, and the diversity of options available to you.
When are Fire Hose Nozzles Used?
Nozzles, for the most part, are the cornerstone of generalised firefighting. This means they are used for core tasks like structural interventions, exterior operations, hose reel adaptation and even washdown or dust suppression. Functionally, the nozzle makes aiming the flow of water much easier. Whether it’s a basic nozzle like the DO9 or one with selectable modes, their purpose is to direct the water where you need it to go.
Other uses of nozzles arise when we consider the different types available. We’ll go a bit more in depth on this soon, but it’s worth noting what certain specialist nozzles can do for a firefighting arsenal. A ‘hydroshield’ or waterwall is a specialised nozzle that creates a protective screen of water. This isn’t for extinguishing the fire directly, but rather for keeping aggressive flames at bay while firefighters approach the source.
It should go without saying that fire hose nozzles are used at just about every stage of the firefighting process. I even mentioned washdown, which is a post-fire procedure intended to decontaminate an area of carcinogenic material. There is other equipment involved in this process, but a reliable nozzle is essential, much like a garden hose being used to clear dirt from a drive or patio.
That leads neatly into another point. The same kind of hose nozzles that the fire brigade use are often used by other operatives. This includes recycling and waste centres, among a wide range of other industrial environments. In these contexts, they are still used for fire protection but play a role in general maintenance tasks as well.
What Kind of Fire Hose Nozzle do I Need?
This is more about the circumstances they are used in, than about which one you need to buy to cover everything. In that vein, however, a selectable nozzle (somewhere around the 475 litres per minute mark) gives the most coverage. They feature modes such as straight, jet, and narrow or wide fog. These functions can, of course, be found across other options; the selectable nozzle is a bit of a show-off.
As it happens, it is typical for hoses to feature at least two modes. The standard hoses, like the DO9, are a bit of an exception, as they only provide simple jet functionality. This is, however, the baseline. A focused, solid jet helps the water penetrate deep into fire zones and push through obstructions so it can hit the fuel source directly. You can get this functionality from standard or selectable nozzles, but there are options like a Jet Spray Hose Nozzle, which is quite a specific two-in-one.
A spray, or fog mode for the water is the second most common nozzle functionality next to the jet. A wide spray is useful for protecting the firefighters (like the waterwall), and provides better area coverage and cooling than a harsh jet. For an actual fog or mist, you’ll need something like a Diffuser Fire Nozzle, but a nozzle that can switch between a jet, cone, or curtain is easy to achieve through the selectable varieties mentioned earlier.
If you’re going to be switching modes frequently, then you want to make sure that pressure fluctuations are accounted for. The Vigil 400 Automatic Fire Nozzle hits this on the head, providing all the spray settings of a selectable, while automatically adjusting the flow rate to compensate for the pressure changes.
What’s the Difference Between Fire Hose Nozzles and Branchpipes?
Actually none! Or, at the very least, they pretty much always come together. The branchpipe is the whole thing, nozzle and all. It’s just a bit of industry and market shorthand that we call them just ‘nozzles’. The nozzle, in reality, is the component at the very end of the whole branchpipe, and nothing else. The nozzle is its own part, but is also synonymous with branchpipe, with both referring to the whole device that attaches to the end of a hose.
So, I hope that clears things up. I hope you also feel well-informed about the role of fire hose nozzles and the different types that are available. Obviously, there’s plenty more variety than what I’ve covered in this article, but I’ve gone over the most prominent types that we offer, as well as things on the more novel (but still eminently useful) side of things, like the waterwall.
