Question

Which is the best fire extinguisher for fires involving electrical equipment and inflammable materials like petrol?

Answer 1

Answer: carbon dioxide

Answer 2

Carbon dioxide

Explanation:

For fires involving electrical equipment and inflammable materials like petrol, carbon dioxide (CO2) is the best extinguisher. CO2, being heavier than oxygen, covers the fire like a blanket. Since the contact between the fuel and oxygen is cut off, the fire is controlled. Water should not be used to control fires involving electrical equipments.  Water is a good conductor of electricity, so it may lead to electric shock.
