Question

You may have seen that when a person accidentally catches fire, people put a blanket around him. Identify the reason for this.

• A. The blanket is non-combustible.
• B. The blanket cuts off the supply of oxygen which in turn stops combustion.
• C. The material of the blanket stops fire.
• D. The blanket reduces burning.

Answer 1

The correct option is B

The blanket cuts off the supply of oxygen which in turn stops combustion.

The essential requirements for producing fire are fuel, air (to supply oxygen), and heat. Fire can be controlled by removing one or more of these requirements.

As oxygen gas is essential for combustion, we can stop the fire by cutting the supply of oxygen. This can be done by wrapping a blanket around the person. So, it stops the combustion and the person can be saved.
