What Are Fire Fighting Hoses & Nozzles?
Fire Fighting hoses and Nozzles refer to an extremely high-pressure hose coupled with a mechanism that produces and aims a stream of water, foam, powder or any other similar fire-extinguishing applicant. A fire hose can ideally be affixed to the traditional fire engines or even fire hydrants. The water pressure of the flow that these hoses sustain is between 800 and 2000 kPa. The most basic hose nozzle mechanism is a tube along with a terminal attachment that regulates the water flow. Firefighting hoses & nozzles can produce tapered or scattered water depending on the need of the moment; further, they also have the function to issue a halt on the water stream without having to close off the supply in actuality.
A fire hose cabinet consisting of fire fighting hoses & nozzles is almost constant in most industrial areas or even residential buildings to prevent a possible fire hazard as a safety precaution. Period cleaning and drying of the hire hose are essential for maintenance and to avoid damage due to accumulated moisture. It is cardinal to have a basic understanding of its constitution and function to ensure the protection of people and commodities inside your property.
Firefighting hoses & nozzles have been made using evolving designs over the years. Over time, these have been suitably improved to feature better material and technology to ensure top-notch safety of the people and efficient and swift fire dousing capacity. Most commonly, fire hoses are manufactured with the use of varied rubber varieties or woven nylon fabrics. These hoses are diversified based on their purpose, use, weight and length suitably. In contrast, the nozzles or fire hose connectors are composed of hardened aluminium or, more typically, brass. These are duly fastened to the hoses, which in turn are secured to a fire engine, hydrant or other similar applicants at the time of need.
Types Of Fire Fighting Hoses & Nozzles:
1. Delivery Hose: This variety of fire fighting hoses & nozzles are obtainable in varied design types such as percolating, unlined, or even canvas hoses that are generally made out of vegetable fibres. Hoses of the non-percolating are created out of plastic substances; inversely, a regulated percolated hose consists of a woven outer layer forged out of vegetable fibre, simply with a plastic or rubber lining. Delivery hoses are attached to a water pump's expulsion point and are typically susceptible to even more pressure than is standard of atmospheric pressure.
2. Suction Hose: These hoses are attached to a pump's suction end and are designed to suit either more or less than the atmospheric pressure. Typically, such hoses are a smooth bore, i.e. entirely embedded or only to a certain degree. Known to be close to ten feet long, they are the most solid of all the fire hoses. These are only partially flexible and are made out of rubber. One might find them at using draining water of water bodies like lakes, rivers or ponds that are not pressure strained.
3. Hose Reel Hose: This is a variety of fire fighting hose & nozzle types created out of reinforced rubber and further aligned with a pivoting joint bound.
4. Forestry Hose: Flexible, light-weight and layered with fabric, these are employed to contend with outdoor fires. Their insubstantial mass allows them to be operated with ease despite being close to a hundred feet in length.
5. Booster Hose: With certain overlapping qualities to a forestry fire hose, these are equally flexible in nature and hundred feet in length. Their point of differentiation is that these are aligned with thick rubber instead of fabric.
6. Supply and Relay Hose: These are the most common variety of hoses you'll see riding in fire engines and hydrants that you glance upon. Supply and relay hoses are made out of fabric and are bigger. These are employed to shoot water streams to douse fires.
7. Attack Hose: Though quite flexible, these are more compact and less lengthy than the other hose varieties mentioned here. Attack hoses are around fifty feet long and are capable of persevering against the increased amount of pressure.
The details mentioned above allude to creating a basic background knowledge about the purpose, operation, and types of fire fighting hoses & nozzles used most frequently by firefighters in your area.
