According to the principle of material combustion and practical experience in combating fire, there are four basic methods for fire extinguishing: cooling, asphyxiation, isolation, and chemical suppression. The first three methods are fire extinguishing through physical processes, and the latter method is fire extinguishing through chemical processes. Store a variety of fixed fire-fighting equipment in the warehouse or use mobile fire extinguishing equipment for fire extinguishing, the fire extinguishing principle is the result of one or more of the above four kinds of fire extinguishing methods.
One (factor) method <br> <br> fuel combustion conditions (a) cooling the fire, under the action of heat and flames to reach ignition, pyrolysis, or steam distillation emitted combustible gases, combustion can be sustained. If the flammable solid is cooled below the auto-ignition point, the flame will be extinguished; the flammable liquid will be cooled below the flash point, and the heat source will be isolated from the outside, so that the gas that can sustain combustion cannot be volatilized and the fire will be extinguished.
The best fire extinguishing agent with the best cooling performance is water. The water has a large heat capacity and a high latent heat of vaporization, and the cooling performance is very good. In particular, the use of fog-like water flow fire extinguishes the effect more significantly.
Building water fire-fighting equipment is not only less investment, convenient operation, good fire-extinguishing effect, low management cost, but also good cooling performance. It is the main fire-fighting facility for fire extinguishing by cooling method.
(Ii) asphyxia asphyxia fire extinguishing method <br> <br> method, the combustion zone is to prevent the inflow of air, or air diluted with a non-combustible material, the combustion of oxygen and combustion material severed off.
When extinguishing a fire by means of asphyxiation in the fire place of a warehouse, asbestos quilts, soaked quilts, canvas, seagrass mats and other non-combustible or nonflammable materials can be used to cover the burning or closed holes; there are steam and inert gases (carbon dioxide). , nitrogen, etc.).
The high-magnification foam fills the combustion zone and uses the existing doors, windows, etc. on the building to close the combustion zone and prevent fresh air from flowing in to reduce the oxygen content of the combustion zone and achieve the purpose of suffocation and combustion. In addition, as a last resort and conditions permit, it can also use water flooding (filling) method to extinguish the fire.
When using the choking method to extinguish fires, the following issues must be noted:
1. The combustion site has a small space, it is easy to plug and seal, and this method can only be used if there is no oxidant in the combustion zone.
2. When using firefighting methods to fight fires, it must be taken into account that water does not produce adverse effects after it has acted on combustible substances.
3. After extinguishing the fire by means of suffocation, it is necessary to open the hole to check when it is confirmed that the fire has gone out and the temperature has dropped, and to prevent the premature opening of the closed space, so that fresh air flows into the burning zone, causing re-ignition or smoke flow. The deflagration of incomplete combustion products in the fire led to a fierce development of the fire.
4. Under conditional conditions, in order to prevent the rapid spread of the situation and fight for the preparation time for firefighting and fighting, temporary temporary choking measures can be taken to reduce the intensity of combustion, and then organize forces to extinguish the fire.
How to organize fire fighting in warehouses
First, the basic method of extinguishing <br> <br> known, three conditions required for combustion: fuel, a comburent and ignition sources. The three are indispensable. In the event of a fire, if certain measures are taken to destroy one of the conditions necessary to maintain the combustion, the combustion cannot continue and the fire will extinguish.
