Have you seen 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 is here to help us to improve our firefighting capabilities as well as remove the limitations that conventional firefighting nozzles was facing since its first introduction. One of these limitations is the manual handling of firefighters on larger diameters, which isn’t possible with the conventional firefighting nozzle due to of the uncontrollable effects of back pressure has brought into. Firemen are typically restricted to using no more than 2.5 inches in diameter of the standard firefighting nozzles because of security concerns and the difficulties to control back pressure by hand. The typical time it takes four men to manage the pressure of a 2.5 inch diameter at 250 psi traditional firefighting nozzle. With this latest technology at disposal, the firefighting industry can now reduce their need for manpower to more than half what they usually need. In addition, this could also be beneficial for communities as well as volunteer fire departments and regions with limited firefighting resources.
The technology helps to eliminate firemen’s biggest worry of whipping nozzles and hoses motion that can be difficult to control and , most important, it could be fatal for anyone’s personal safety. With the no-back pressure system, the nozzle could be dropped onto the floor at a pressure of 250 psi and then it just lay there with no movement. It’s a moment of joy for the majority firefighters who don’t need to expend so much energy to counter and get control of back pressure. Instead, they will be able to save energy by keeping their position and efficiency for a longer time to put out fires. The disadvantages of the conventional firefighting nozzles is that the greater the diameter , the higher the back pressure, so it must be positioned on a sturdy foundation or ground to help increase the pressure that it must manage. With the advent of new technologies, they have transformed the idea of what a the firefighting nozzle is capable of doing beyond what was exclusively known in the conventional.
In terms of safety the latest technology has moved from being risky to a safe and firefighting-friendly device. It does not require to be anchored and mounted on a firetruck , or a foundation that is stationary to make a difference in its use. With the elimination of back pressure, it can be utilized as a firefighter’s equipment that can be carried by anyone who is now be able access areas that firetrucks are unable to accomplish. Small fireboats employed to put out fires from ships can now take waters directly from the sea and then shoot a huge stream of water using high pressure pumps without worrying of shaking the boat. However, it is believed that the possibilities of this technology do not end with fighting fires . Instead, its utility extends beyond the possibilities that are not being spotted by us at the moment.
Herewith. Some amazing details on the advantages 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 extremely fine particle, it also has a surface 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 from the flame so quickly that fires usually go out faster and using less water as opposed to conventional nozzles that have back pressure.
b) Since fires quickly put out and with less water, damage caused by water, fire and smoke is drastically diminished. The rapid conversion of steam can reduce the smoke and it sucks it to the ceiling leaving the bottom area visually unhindered, which is hugely beneficial in the rescue and retrieval process.
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 amount of water needed for the process of putting out the fire has been drastically reduced and as a result can also help prevent any further damage caused by excessive water levels in the building.
e) The nozzle for firefighting that does not have back pressure as a result can be produced at a lower cost as compared to the conventional one, and is not a moving part so there is minimal to no maintenance to be done.
f) In the firefighting nozzle with no the backpressure, it produces the most cooling effect that firefighters are able to work closer to the flames in a safe manner and increase the chance of rescuing victims of fire.
grams) It can be combined in conjunction with any material to create foam. Through testing, the product has outperformed the quantity and quality of the majority of foaming equipment available on the market in the present. The tests conducted by firefighters across the US using FXA foaming material however, they were not successful in reigniting the flames after they were taken out.
h) Finally, there are numerous benefits to be gained from this breakthrough technology economically but the safety benefits from this is greater than the economic advantages.
