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.
As a firefighter, an individual has to be aware of all the equipment involved and their functions. This is what easily distinguishes them from regular onlookers on a scene.in the event of choosing a hose nozzle, it is imperative that you are capable of understanding its capabilities in conjunction with current system in place. This is performed through flow testing. Flow testing helps in determining penetration and reaction force which is appropriate for use.
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.
Supplies stores usually stock a variety of nozzles. A smooth bore nozzle is the first example. This type of nozzle has existed for long due to its share of merits. In this regard, many services in America embrace it. It is thus able to produce large amount s of water so that the blazing fire can be put off permanently.
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 other type is the broken or aspirated stream nozzle which provides great mobility at low pressures. They are normally larger than other types and work by aspirating the stream as it travels through the tip. This helps in the production of large water droplets which absorb the heat. In addition to that is suitable for foam application. The bad thing with them is that they are quite expensive and are heavier to carry around.
Regardless of the type, the hose should also be maintained effectively. This is done by ensuring that it is hung to dry. Failure to do this contributes to deterioration since the standing water will render it unreliable in the long run. Additionally, frequent check up by a specialist will save you the burden of arriving at a situation only to find out that the equipment is not functioning.
Even though a wide variety of nozzles exist in the market, the selection criteria depend on flow testing. Individuals should keep in mind that the goal is to deliver large amount of water for putting off the flames. The right equipment will render efficient services when in use.
