What are the four basic methods of fire extinguishers?
Method: to prevent choking air into the combustion zone or not dilute combustible substances so that combustion air, not enough oxygen out. Practical application, such as stone, cotton blanket, wet sacks, sand, fire extinguishers and other fire or difficult burning material covered in the object; closed cabin, building fire the doors and windows, such as holes and equipment container cover, choking combustion source.
Chemical inhibition extinguishing method: chemical extinguishing chemical reaction agent is sprayed into the combustion zone to participate in combustion, so that combustion stop. Fire extinguishing agent used by the fire extinguishing method has lapras licensing efficient fire extinguisher.
Cooling method. The fire extinguishing agent is injected directly into the combustion; to reduce combustion temperature. When the combustion temperature decreased to the temperature of the combustion, and then stop. Or the fire extinguishing agent is sprayed onto the combustible fire nearby, prevent radiation heat affected and fire.
Isolation method: fire place or object and the surrounding combustibles isolated or removed, the combustion will be due to a lack of combustible material and stop. In practice, such as near the fire, combustible flammable and combustion items removed the fire; the object moved to a safe place; close the flammable gas and liquid pipeline valve, reduce and terminate the combustible material into the combustion area.
