    p.310. How is the method of dispersing the flammable substance in extinguishing the fire by cooling?


    C.310. Dispersing the combustible material: By dispersing the burning material, the high heat that causes the fire is divided, the split heat decreases and the fire gradually goes out. In fuel oil fires, this type of extinguishing is not applied as it will cause the fire to spread.


    S.311. How is the strong blowing method used to extinguish the fire by cooling it?


    C.311. Strongly blown air on the burning material causes the flame to extinguish and the temperature of the burning material to decrease. With this type of (by cooling) extinguishing principle, success can be achieved in initial fires. In fires that have grown or have reached certain dimensions, strong blowing will cause the fire to grow as it will provide more oxygen to the fire. For this reason, such extinguishing is not used on large fires.


    p.312. In which fires is the strong blowing method not applied to extinguish the fire by cooling?


    C.312. such extinguishing is not used on large fires.


    P.313. In which fires is the method of dispersing the flammable substance not applied in extinguishing the fire by cooling?


    C.313. In fuel oil fires, this type of extinguishing is not applied as it will cause the fire to spread.


    P.314. How to extinguish the fire with the method of cutting the air?



    A-Covering: It is the extinguishing made by cutting the contact of the burning substance with oxygen by using solid materials (sand, soil, carpet, rug, etc.) and chemical compounds (foam, chlorine, nitrogen, etc.). Chemicals that cover fuel fires are used.

    B-Stroke: It is the process done to cut off or reduce the contact of fire with oxygen. It is especially applied to fires occurring in closed places.

    C- Elimination of combustible material: It is the extinguishing of the fire as a result of the disappearance of the flammable substance, which is one of the combustion conditions.


    Q.315. What are fire extinguishing agents?



    • A-Water
    • B-Sand
    • C- Carbon dioxide gas (CO2)
    • C- Dry chemical powder
    • D- Foam


    S.316. Tell us about water, which is one of the fire extinguishers?


    C.316. Water: It is the most important substance among fire extinguishing agents. Water is an excellent (solid) extinguisher, especially for type A fires.


    P.317. Tell us about sand, which is one of the fire extinguishing materials?


    C.317. It is used to extinguish flammable materials by cutting off their relationship with oxygen. It should be ensured that the sand completely covers the combustible material at the time of use.


    P.318. of fire extinguishing agents Explain Carbon Dioxide Gas (CO2)?


    C.318. The carbon dioxide gas, which covers the burning material, extinguishes the fire by leaving the combustible material without oxygen. Carbon dioxide gas is kept in a liquid state under pressure, usually in steel cylinders. With this gas, it is very difficult to extinguish the fire in open areas and places where there is air flow.


    P.319. of fire extinguishing agents Can you describe dry chemical powder?


    C.319. One of the active substances used in fire extinguishing is dry chemical powder. Class A, B and C fires can be effectively extinguished with the help of chemical powders. Fires caused by excessive heat in materials such as wood, fabric, car tires, fires caused by the ignition of gasoline and derivatives liquids, and air gas, natural gas, etc. Dry chemical powders are used to extinguish fires that occur as a result of flammable gases coming out from under pressure.


    P.320. of fire extinguishing agents Can you describe the foam?


    S.320. The foam completely covers the burning surface. As a result, it cuts off contact with air and is also used as a fire extinguisher due to its cooling feature.

    • F- Be very careful in welding and cutting processes.
    • G- Unqualified persons should not touch the electrical equipment.
    • H- Kitchens and bathrooms where LPG cylinders are located should be ventilated continuously.
    • I- Taking precautions against fire in your home and workplace is not as expensive as it is thought, on the contrary, it is cheap. Moreover, since fire protection devices and equipment are manufactured with high quality and robustness, they are long-lasting and can serve for years.


    Q.324. What actions should be taken when faced with fire?



    • A-Don't be alarmed.
    • B- If there is a fire alarm button in the place, it should be pressed.
    • C- The fire department should be informed by dialing 110 by telephone.
    • Ç-Fire address should be defined according to the shortest, most accurate and obvious places known to everyone.
