Fire is regarded as the chemical reaction that utilizes fuel coupled with oxygen. When the two are available in abundance, it will continue burning.in order to control it, the appropriate amount of water should be delivered using a good fire hose nozzle. This equipment has been characterized as the most essential when it comes to flame control. They need to be well taken care of in the way a soldier takes good care of his or her gun.
The knowledge about firefighting equipment is what distinguishes fighters from civilians. When selecting a nozzle, it is imperative that an individual understands its capabilities with the current system. This is carried out through flow testing. This will determine whether the penetration and reaction force is suitable for use by the firefighter.
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.
There are various types of nozzles available in the market today. To begin with, there is the one with a smooth bore . This has been in existence for quite some time and is widely used by many stations in America. This is because it produces the greatest reach while utilizing the lowest engine pump pressures. By so doing, large amounts of water are deposited in a bid to put out the flames.
One of the good things with them is that its cost is quite pocket friendly. In this regard, many fire services are able to purchase them for use in their operations. Additionally, various sizes are in existence and are usually designed to ensure more gallons per minute flow. The other advantage is the fact that there is no moving parts, hence making it simpler to use. However, a particular shortcoming related to is the absence of foam production and poor hydraulic ventilation limits is usage in some circumstances.
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.
In as much as there are a number of nozzle types in the market, the bottom line when it comes to selection lies with flow testing. Remember the main goal is to deliver as much water as possible. By so doing, the individual will be able to select his or her suitable nozzle for use in firefighting scenes.
