Question

Why sand is used instead of water to put out electric fire?

• A. Water can cause explosion.
  
• B. Water does not have charge carriers.
• C. Sand has charge carriers.
• D. Sand does not have charge carriers.

Answer 1

The correct option is D Sand does not have charge carriers.

In case of an electric fire, water isn't the fire extinguisher. This is because water acts as an electrolyte and can prove to be the fuel for the fire. Thus, we need a substance that doesn't have ions or charge carriers. Sand is a substance that doesn't have charge carriers. Hence, sand is used in case of an electric fire.
