Extinguishing range of foam fire extinguisher: Suitable for fighting Class A fires, such as wood, cotton, hemp, paper and other fires, but also fighting general fires, such as petroleum products, oils and fats, but not fire fighting water-based flammable fires. , flammable liquid fires, such as alcohol, esters, ethers, ketones and other substances in the fire. 2. The function of dry powder fire extinguisher dry powder fire extinguisher is as follows: Firstly, it eliminates the active ions produced by the combustion and interrupts the chain reaction of combustion; Second, the dry powder absorbs a lot of heat when it is decomposed by high temperature, and releases steam and carbon dioxide to achieve cooling. And dilute the role of oxygen in the combustion zone air. Dry powder extinguisher fire extinguishing range: Suitable for fighting flammable liquids, gases, electrical fires, and fires that should not be used to fight water. AC dry powder fire extinguishers can prevent the fire of charged materials and fires of Class A, B, C and D materials. 3, carbon dioxide fire extinguisher CO2 fire extinguishing effect of the fire extinguisher: When the combustion zone carbon dioxide in the air content reaches 30% -50%, can make the extinguishment of combustion, mainly from the choking effect, while carbon dioxide in the jet fire extinguishing process absorbs certain heat energy, It also has a certain cooling effect. Carbon dioxide fire extinguishing range: Suitable for fighting fires of electrical equipment, precision instruments, books and archives below 600 volts, as well as fires of oils, gases, and materials that cannot be used to save water.
4,1211 fire extinguishers 1211 fire extinguishers fire extinguishing performance is: mainly to suppress the chain reaction of combustion, to stop the combustion. At the same time there are some cooling and suffocation.
Extinguishing range of fire extinguisher 1211: Suitable for fighting flammable, flammable liquids, gases and live equipment fire, but also for solid material surface fire (such as bamboo, paper, fabrics, etc.), especially for extinguishing precision instruments, computers, The fires of valuable cultural relics and valuable material warehouses can also put an end to the initial fire of aircrafts, automobiles, ships, hotels and other places. (II) How to use the fire extinguisher 1. Use of portable fire extinguisher (1) Mechanical foam, 1211, Carbon dioxide, Dry powder fire extinguisher These fire extinguishers are generally made by one person. When used, the fire extinguisher is quickly referred to the fire, and the fire extinguisher is put down at a distance of 5 meters from the fire point. Remove the safety seal first, remove the safety pin, and then grasp the handle with your right hand. Hold the nozzle on the front of the spray hose (without the spray hose, the left hand can hold the base ring of the fire extinguisher) at the front of the spray hose.
When the fire is extinguished, the nozzle should be directed at the root of the fire, fired from near to far, left and right, and quickly advanced until the flame is completely extinguished. When the foam extinguishes the oil fire, the foam should be sprayed on the wall of the large container so that the foam flows down the wall and covers the surface of the oil product in parallel, thereby avoiding the foam directly hitting the surface of the oil product and increasing the difficulty of extinguishing the fire. (2) The chemical foam fire extinguisher will lift the fire extinguisher upright and point it 10 meters away from the fire point. The user holds the ring with one hand, and the other hand grips the bottom ring of the barrel to turn the fire extinguisher upside down. The foam can be sprayed. During the foaming process, the fire extinguisher should always be upside down and vertical, not horizontal or upright. Otherwise, the spray will be interrupted. 2, the use of cart fire extinguisher
