Have you ever heard of a fire nozzle held up with no back? Well, zero back-pressure technology for firefighting nozzle that is here with us now, is to remain, so we have fire and constraints for free update our ability to rise to such conventional firefighting nozzle had its foundation here. One of these limitations, the handling of fire on large diameters is not possible for conventionalFire nozzle to the uncontrolled effects of pressure that brought the fire inside are generally limited only to use no more than 2.5 inch diameter conventional firefighting nozzle because of security concerns and the difficulty of containing the pressure manually. It took four men usually control the nozzle of a conventional 2.5-inch to 250 psi fire. With this new technology at hand, industry could reduce the fire brigade now in a positionthe strength of demand for labor by more than half of what would normally require. Not only that, this could also be beneficial, municipalities, volunteer fire department and the fire areas with limited resources.
The technology itself helps to eliminate firefighter to worry about a hose nozzle and whipped cream action, control is usually difficult to be anyone's personal safety and, especially, can be deadly. In the absence of pressure against the technology, a nozzlefell down to 250 psi and remained there without moving. It 's really a sigh of relief for most of the firefighter who is not so much energy in the fight against the pressure and get exercise, but may be able to recharge the batteries, maintaining their position and activity on a longer period of time in creating fire. The disadvantages of conventional firefighting nozzle, the larger the diameter the greater the pressureis, therefore, is on solid ground or foundation to use hard-pressure, must contain to be mounted. With the new technology is changing the perception of what the fire fighting nozzle can do what was just beyond the notes.
In the aspect of safety, the new technology in a fire hazard and risk free and emancipated, friendly fire-fighting equipment. Should not be set up and a fire truck or a foundation be established steadyeffective to use. You can now eliminate the pressure as a portable fire fighting equipment from someone who may now be able to areas where the fire service can not access hardly be maintained. Small boats used in starting the fire ship fire can now draw water from the sea and run a large current with high pressure pumps, without rocking the boat only for treatment. It is considered that the potential applications of this technology is not fighting the fire, but towards the endits usefulness goes beyond what previously has not seen yet.
With this. are some surprising data on the characteristics and advantages of this new technology, in particular:
a) The nozzle of the fire, with no back pressure is designed to spray water particles in a very refined, a surface that can absorb up to one hundred times more heat than the normal flow of water used to fight fires instantaneous steam conversion, thisextended surface can suck the warmth of a fire so fast that the fires are generally clear faster with less water than conventional nozzles with pressure.
b) There is to extinguish fires faster with less water, reduces damage from fire, water and smoke. The rapid transition to steam reduces smoke and suck visually opening up the top of the room, leaving the lower part, which may be a lift to the rescue and recoveryOperations.
c) The flow of the water jet emitted from a "soft" that do not break or damage he has done, and be done with conventional nozzles.
d) The amount of water for the implementation of the fire is dramatically reduced and they need to avoid even more damage by excess water in the building.
e) The nozzle of the fire, without pressure to return as a product is cheaper than conventional products, has no movingParties, then there is little to no maintenance.
f) The fire-fighting nozzle without back pressure, has a high cooling effect, the firefighters at work certainly closer to the fire, which increase the chances of rescue fire victims.
g) can be used with any type of material to produce foam. During the tests, the quantity and quality of most devices, the foam is available on the market today exceeded. Test carried out in the fire serviceUSA used foam FXA, failed to light the fire when they were introduced.
h) Finally, there are a lot of benefits that may result from this new technology commercially, but the turning point safety factor exceed the economic benefits.
