Fire Hose and Nozzle

What Is a Fire Hydrant?     A fire hydrant is a fixed fire-fighting facility. Its main functions are to control combustibles, isolate oxidizers, and eliminate ignition sources. Fire hydrants are mainly divided into indoor fire hydrants and outdoor fire hydrants. For the general public, indoor fire hydrants are the most commonly used type. Indoor Fire Hydrants Indoor fire hydrants are widely used fire-extinguishing systems in buildings and serve as one of the key facilities for putting out indoor fires. The components inside an indoor fire hydrant cabinet include: Fire hose，Fire nozzle，Hydrant valve，Fire hydrant alarm button Some fire hydrant cabinets may also be equipped with a fire hose reel (portable fire water hose) and fire extinguishers. Indoor fire hydrants should be installed in public shared spaces such as corridors or halls. They are usually built into the walls of these spaces. Regardless of the decoration applied around them, they must have a clear label (marked "Fire Hydrant") and no obstacles placed in front of them—this prevents interference with the opening of the hydrant cabinet door.   How to Use Fire Hydrant?   How to use it correctly? The following step-by-step guide (with visual references) will help you master the operation of an indoor fire hydrant.   Step1 One person presses the switch to open the hydrant cabinet door, then takes out the fire hose and fire nozzle. Step2 Unfold the fire hose completely. Leave one hose connector on the ground, connect the other connector to the fire nozzle, and then move toward the fire site. Step3 Another person connects the free end of the fire hose to the water outlet of the hydrant, and helps to fully spread and straighten the hose. Step4 The person at the fire site stands in an effective position upwind or at an oblique upwind direction relative to the fire. Hold the fire nozzle with one hand and grip the connection between the nozzle and the hose with the other. Bend the front leg and straighten the back leg to get into a stable water-spraying posture. Step5 The other person, after ensuring the hose is properly arranged, quickly returns to the fire hydrant. Press the water pump start button, then turn the water outlet valve counterclockwise to the fully open position. Step6 Once water flows out, the person holding the nozzle keeps a firm grip. Aim the water jet at the base of the flame, spray in a left-right swinging motion, and slowly move forward from near to far to extinguish the fire completely.
