Fire fighting
The basic method of fire fighting
Suffocation fire extinguishing method.
The suffocation fire extinguishing method is to take appropriate measures to prevent the air from flowing into the combustion area according to the condition that sufficient air (oxygen) is required for the combustion of combustibles, or to use non-combustible materials and inert gases to dilute the oxygen content in the air, so that the combustion materials are extinguished due to the lack of oxygen to support combustion. This method of extinguishing fire is suitable for extinguishing fires in closed rooms and production plants and equipment containers.
Cooling fire extinguishing method.
The cooling fire extinguishing method is based on the condition that the combustion of combustibles must reach a certain temperature, and sprays water or fire extinguishing agent directly on the combustible materials to reduce the temperature of the combustible materials below the ignition point, thereby terminating the combustion. This method can also be used to cool objects that have not yet burned, such as building components, equipment, etc., to avoid them from burning or burning due to thermal radiation.
Isolation fire extinguishing method.
The Isolation Fire Extinguishing Method isolates combustibles adjacent to combustibles based on the condition that combustibles must be present for combustion to occur, and prevents further spread of combustion.
Inhibition of fire extinguishing methods.
The inhibition fire extinguishing method is to spray the fire extinguishing agent on the combustible, so that it can participate in the combustion reaction, so that the free radicals generated in the combustion disappear, and a stable molecule or low activity free radicals are formed, so that the combustion is terminated.
