Question

Water is the best extinguisher for fires involving electrical equipment. (True or False). Also write the false statements in their correct form.

• A. True
• B. False

Answer 1

The correct option is B False

Fire extinguisher:

• A fire extinguisher is used to control small fires.
• A fire extinguisher contains chemicals such as Sulfuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$ and Sodium bicarbonate $\left({\mathrm{NaHCO}}_3\right)$.

Working of Fire extinguisher:

• When the fire extinguisher is operated by pressing the knob, the sulphuric acid reacts with sodium bicarbonate solution leading to the production of carbon dioxide gas $\left({\mathrm{CO}}_2\right)$.
• The producing carbon dioxide is non-combustible. "As the contact between the fuel and oxygen is cut off, the fire is controlled".

“Water is the best extinguisher for fires involving electrical equipment.” This statement is false as water does not work as an extinguisher to control fires.

The correct statement is-"Carbon dioxide is the best extinguisher for fires involving electrical equipment."
