Have you had the opportunity to use a hand-held firefighting nozzle without back pressure? It’s true that the zero-back pressure technology for firefighting nozzles are in the present, and must stay in place to allow us to improve our firefighting capabilities and eliminate the limitations that conventional firefighting nozzles was facing since its beginning. One of the limitations is the manual handling of firefighters with larger diameters, which isn’t possible with conventional firefighting nozzles because due to the uncontrollable impact of back pressure has brought into. Firemen are generally restricted to using no more than 2.5 inches of diameter for the conventional firefighting nozzles because of security concerns and the inability to manage back pressure by hand. The typical time it takes four men to manage the back pressure of a 2.5 inch diameter at 250 psi traditional firefighting nozzle. With this latest technology at fingertips, the industry of firefighting can now reduce their need for manpower in half the amount they typically need. In addition, this can be advantageous for communities as well as volunteer fire departments and areas that have limited resources for firefighting.
The technology helps to eliminate firemen’s biggest worry of whipping nozzles and hoses motion that can be difficult to control and , most crucially, it can be deadly for anyone’s personal safety. With no back pressure technique, a fire hose could be dropped onto the floor at 250 PSI and will just sit there, without moving. It’s a moment of joy for the majority of the firefighters, who don’t need to expend so much effort in battling and gaining grip against the back pressure. Instead, they will be able to save energy by keeping their position and efficiency for a longer time when it comes to putting out fires. One of the disadvantages of traditional firefighting nozzles, the larger its diameter, the more back pressure will be, and it should be placed on a solid foundation or ground to help increase the pressure that it must manage. Thanks to the advancement in technologies, they have transformed the way we think about what a the firefighting nozzle is capable of doing beyond what was exclusively known in the conventional.
In terms of safety it has moved from being risky to a non-risky and firefighting-friendly device. It does not require to be fixed and mounted to a firetruck or foundation that is stationary to have a successful use. With the elimination of back pressure, it is now able to be used as a portable firefighting apparatus by anyone who is now be able to reach places that firetrucks can’t accomplish. Small fireboats utilized to stop ship fires are now able to suck water directly from the ocean and release a massive stream using high-pressure pumps, without having to be concerned about rocking the boat. There is a belief, however that the possibilities of this technology don’t end with fighting fires . Instead, its utility extends beyond what is not yet recognized by us in the present.
Herewith. Some amazing details about the benefits and features of this latest technology, to include:
A) This nozzle for fighting fires that has no back pressure was created to break up water into very small particles. It has a surface that is capable of absorbing 100 to a hundred times the heat of the standard stream of water to fight fires, thanks to instantaneous conversion into steam. this expanded surface is able to draw the heat away from the flame so quickly that fires can be put out quicker and with less water as compared to a conventional nozzle that have back pressure.
b) Since fires quickly put out by using less water, the damage caused by water, fire and smoke is drastically diminished. The speedy conversion to steam can reduce the smoke and draws it to the ceiling leaving the lower part accessible, which is an enormous help when it comes to rescue and retrieval.
C) The water stream that is released from the nozzle is “soft” that it will not tear or harm the way it was able to do with traditional nozzles.
d) The quantity of water needed in the process of putting out the fire has dramatically decreased and, in doing so can also help prevent any further damage caused by excessive water levels in the building.
e) The firefighting nozzle that is not subject to back pressure, as a product can be produced at a lower cost as compared to the conventional one, and does not have moving parts so there is minimal to no maintenance to be done.
f) In the firefighting nozzle with no backing pressure creates the most cooling effect that firefighters are able to work closer to the flames in a safe manner increasing the chances of rescuing victims of fire.
G) It can be combined with any kind of material to make foam. Through testing, the product has outperformed the amount and quality of the majority of foaming equipment available on the market in the present. The tests conducted by department of fire across the US using FXA foaming material did not show that they were successful in reigniting the flames after they were removed.
h) Finally, there are numerous benefits to be gained from this technology in terms of economic benefits but the safety benefits from this advancements outweigh the benefits to economics.
