First, fire fighting: fire fighting is the general term for preventing and fighting fires.
A. Conditions for fire extinguishing and combustion: control combustible materials, isolate combustion-supporting materials, eliminate fire sources, destroy combustion conditions, and finally achieve the purpose of fire prevention.
B. Fire extinguishing: According to different combustion conditions, different fire extinguishing methods (suffocation, cooling, isolation and suppression) are adopted. Sometimes several methods are even used to grasp the attack opportunity and assist in cooperation, so that the existing combustion conditions are destroyed and the fire is extinguished quickly and effectively.
C, pay attention to the smooth flow of fire exits.
Second, four basic fire extinguishing methods
1. Asphyxiation fire extinguishing method: Asphyxiation fire extinguishing method is to take appropriate measures to prevent the air from flowing into the combustion zone, or dilute the oxygen content in the air with noncombustible substances or inert gases according to the conditions that combustible materials need enough air (oxygen) for combustion, so that combustible materials can be extinguished in the absence of oxygen. This fire extinguishing method is suitable for fire extinguishing in closed rooms, production devices and equipment containers.
2. Cooling fire extinguishing method: The cooling fire extinguishing method is to spray water or fire extinguishing agent directly on the burning object according to the condition that the combustible material must reach a certain temperature when burning, so as to reduce the temperature of the burning object below the ignition point, thus terminating the combustion.
3. Isolation fire extinguishing method: The isolation fire extinguishing method is based on the condition that combustible materials must be available for combustion to stop burning, and the combustible materials are isolated near the combustible materials.
4. Suppression fire extinguishing method: Suppression fire extinguishing method is to spray fire extinguishing agent on the burning object and participate in the combustion reaction process, so that the free radicals generated in the combustion disappear and form stable molecules or low-activity free radicals, thus ending the combustion.
