How to operate the water gun correctly?

GRS New DC-Spray Multipurpose Water Gun

With the emergence of pistol grip guns, the firefighters' skills in handling water guns have become worse and worse. When shooting with a water gun, everyone will be as cool as a cowboy or sharpshooter. I have seen every newcomer who has grown from a novice to an experienced one. They all use this type of gun handle gun. Water gun without gun handle

The same water stream as a water gun with a handle handle can be sprayed. The purpose of designing the gun handle type water gun is to facilitate the firefighters to operate the water gun, but the firefighters must not operate the water gun alone. Gun handle type water gun is a better kind of gun, it has many advantages. Due to the emergence of gun-type handle water guns, we have forgotten the basic points of correctly and effectively operating the water gun. If we insist on the training of the basic operational skills of firefighters, and in this case the proper use of water guns, firefighters will play the biggest role in fighting fires.

Manipulating a water strip requires at least two people. The reaction force caused by the flow of water in the hose makes it difficult for the person controlling the hose to control. This is why two people are required to complete the task of manipulating the hose. As shown in Figure 1 , the firefighters manipulated the water gun through the handle-handle. Look to see how close the nozzle of the water gun is to the firefighter's body. The firefighter could not move the water gun to a more effective shooting position. He had to move the entire body to move the water gun up and down. This was due to the fact that the firefighters behind him did not play their due role. He had to deal with the reaction force of the water gun and the movement of the water gun became more difficult. While the firefighter is bringing the water gun close to the body to respond to the gun's reaction, he must move the entire body to control the water gun.

Any gun that is being used has a counter force. The amount of reaction force depends on the flow of water in the hose. The greater the flow and water pressure, the greater the reaction force of water. Under the counteraction of the water gun, a firefighter cannot control the water gun for a long time unless fatigue is eliminated as quickly as possible. This is why there is also a need for the help of a firefighter behind him. An important task of the firefighter is to divert the reaction of the water from the firefighters who held the water guns in front of him. With the support of players behind them, firefighters with water guns in front can control the water gun flexibly and freely.

How can we achieve this ? We use the basic skill training to achieve the correct water gun operation. Regardless of whether you have a gun-type handle gun or a simple nozzle gun, basic skill training is useful at any time.

In Figure 2 , we can see the role of operational skills training. Pay attention to the distance between the nozzle of the water gun and the body of the firefighter. The nozzle of the water gun has one arm length to the firefighter's body. When the firefighter's arm is fully deployed, he can grab the nozzle in the closed state. By controlling the water gun in this position, the firefighters can move the water up and down and left and right without moving the body and shoot the water wherever he wants to. When the water gun opens, the firefighters can use the water behind the interface to enhance the control of the water flow.

Take a look at the hose in the hands of the first firefighter. The water zone is near his right jaw near the body, and his right hand grips the water to bring a fixed and physical distance. His right arm is placed on his right leg to reduce the weight of the hose, which maximizes the time it takes to control the hose. Firefighters can use this position to freely swing the hose, allowing the water gun to spray the water column in any direction, and to prepare for water spray in advance when needed. As shown in Figure 2 , the nozzle for the water gun is in front of the firefighter's body and the firefighters can hold the hose firmly while the hose is shaking. If a gun-type handle gun is used in the posture of the firefighter in FIG. 1 , once his companion relaxes the control of the hose, the nozzle of the water gun may fall out of his hand. If he holds the nozzle of the water gun like the firefighter in Figure 2 , even if his companion relaxes the control of the hose, he can still hold the nozzle of the water gun and will not let go, and it is safe to do so. Firefighters can use this position to predict the direction of the hose's shaking and to control the hose more effectively. This is another topic that needs to be discussed.

The rear firefighters in Figure 2 are also important. His job is to assist firefighters who hold water nozzles. When we train new recruits, we put one of our arms behind our backs and one foot behind the firefighter who holds the nozzle of the water gun, just as each International Fire Service Training Association (IFSTA) training outline requires. Does this have any effect ? This will make the picture look more beautiful, but almost nothing will affect it. Note the positional relationship between the front and rear firefighters in Figure 2 . The firefighter behind him used his entire body to stand against his companions and to hold the hose in both hands. With this posture, he can eliminate the reaction force from the front firefighter's grip on the water gun nozzle and at the same time assist the front firefighter in controlling the water gun. ( This position plays a crucial role in the movement of the hose when the hose advances. ) The rear firefighter must ensure that the hose is always in a straight line so that he can control the reaction force of the water gun and thus ensure the front Firefighters can control the water gun normally. Once the hose is not in line, the reaction force of the nozzle of the water gun will directly affect the front firefighters. This is crucial for the firefighters to wield the water column. Regardless of how firefighters holding water nozzles change direction and move nozzles, the firefighter behind them must keep pace with him to ensure that the hose is in a straight line. Notice how straight the water in Figure 3 is.

Until now, we see in the photo is 11/2-diameter hose, this caliber than water hose 21/2 aperture with easier to manipulate. Our results discussed above are equally applicable to the 21/2-diameter hose. In Figure 3 , the rear firefighters used a different action to assist the front firefighter in controlling the water gun. He is facing backwards, with the entire back against the firefighter in front of the water gun, in this position he can control the hose longer and keep monitoring the situation. Another control 21/2 diameter hose operation is maintained as before while the operation of the gun grip a knee against the water tape (pressure on the body weight). This posture allows a single firefighter to persist for longer waiting for peer support.

The training of basic operational skills of water guns makes firefighters more trained and they can play a greater role in fighting fires.
