    Which of the following is the best extinguisher for inflammable materials?

    A)                          Water                

    B)                                         Sulphur dioxide                

    C)                                         Carbon dioxide                

    D)                                         Carbon monoxide

    Correct Answer: C

    Solution :

    Carbon dioxide is the best extinguisher for inflammable materials like petrol, because it is heavier than oxygen, it covers fire like a blanket. Since, the contact between the fuel and oxygen is cut off, the fire is controlled. Secondly, it does not harm the electrical equipment.                 It can also be used to put out fires involving electrical equipment.
