Fire can be described as a chemical reaction which uses fuel together with oxygen. In the event that oxygen and fuel are in plenty, the reaction will proceed indefinitely. In order to control this effect, a good amount of water needs to be deposited by the use of an efficient fire hose nozzle. This equipment is a prerequisite for effective flame control. Firefighters therefore, have a need to take good care of them in the manner in which soldiers care for their weapons.

Firefighters are easily distinguished from normal civilians through the expertise in handling fire equipment. Before choosing a nozzle, it is important that the user is aware of whether its capabilities match that of the system in place. One way of doing this is to administer flow testing. It is only through flow testing that penetration together with force of reaction are determined.

When utilizing various nozzles, it is essential to keep in mind that the actual flow may be affected by a number of variables. These include increasing friction loss, different pump pressures, issues with water supply and so on. Many a times water may not make it to the tip since some of them perform better than the others. The best thing to do is to test it under ideal and poor conditions to see its functionality rate in such situations.

The current market presents a number of nozzle types. Smooth bore nozzles are the first example. This equipment has existed for quite a long period of time. It is mainly used by the American firefighting services. Perhaps is because of the fact that it utilizes a lower engine pump pressure. This helps a great deal in depositing large water amounts so as to deal with flames.

It also has got its share of advantages which makes it suitable for use. The cost of this equipment is the market is significantly lower and most departments can be able to afford. There are also multiple sizes that are designed for a good flow. The only drawback is that there is poor foam production and the hydraulic ventilation is also not that perfect.

The aspirated stream is another example available in the market. This normally ensures easier mobility and has a bigger structure. It operates by aspirating stream of water as it travels through the tip. In this case, huge droplets of water are gushed out hence assisting in absorption of excess heat. Additionally, foam application can also be made possible. However its expensiveness and size makes it daunting for most stations to put it to use.

It is important that the hose be handled and maintained properly. In most cases, professionals recommend that they need to be hung to dry. When this is not done, the accumulation of water will lead to its unreliability as it may start wearing out. Frequent checkup by a specialist will also save an individual the trouble of realizing that a hose is not functional when such cases arise.

The selection method solely depends on flow testing. The better the flow, the more efficient it can be. Remember, the motive is to deliver huge amounts of water. The choice of the right equipment will definitely make the work easier for the personnel.
