What is the air vacuum water?

Air pressure (APW) is a substance used for conventional fire extinguishers known as APW fire extinguishers. Most often you can see in residential halls and businesses where there are no computers or chemicals. Water at air pressure is nothing special; It is just water and pressure air combined to build a stronger stream of water, as well as high -performance sprayed weapons. While the APW fire extinguishers are common, they can only be used for class A fires A. When used on other fires, these fire extinguishers actually worsen fire. The water on the air pressure contained in them is nothing special in them and they are really just a little more than a large spray weapon. To form air water, the fire extinguisher is filled with two -thirds of water, while the air fills the second third. Water and air are normal; There are no special ingredients. The use of pressurized air ensures that water will flow if necessary for Firefighing.

There are four classes of fire: A, B, C and D. and includes common flammable material such wood and paper; B is for liquids like gasoline; C indicates electric fire; and D indicates chemical fire. Air pressure is only useful for class A fires, which are the most common fires in homes, businesses without chemicals and a large number of computers and residences. If the APW fire extinguisher is used on any of the other three classes, the fire can worsen the fire by spraying fire or liquid or by making an electricity into the fire extinguisher.

APW fire extinguishers are often used on or near electrical equipment when the computer ignites fire or material near computer combustion. These fire extinguishers can be used unless the class C fire extinguisher is available. Before using air pressure water, the device must be disconnected and the Befor must pass for several minutes. The power is completely exhausted. If the fire extinguisher is used before disconnectedI do electricity into the fire extinguisher, causing an explosion or causing injury to the operator.

In order to fight the fire, the fire extinguisher substance must be able to reduce one or more aspects of a fire triangle, a diagram that shows three aspects of fire. These aspects are air, heat and fuel. Water at air pressure kills fire by reducing the thermal aspect of fire and cooling until the fire is gone.
