Question

Why do we cover a burning person in the blanket as a first aid

Answer 1

we cover a burning person in the blanket as a first aid because, as we know burning requires oxygen.so, when we cover the person with blanket, the oxygen supply is cut off leading to extinguish the fire and the person is saved.

Answer 2

In order for a fire to burn, all three elements of the fire triangle must be present: heat, fuel and oxygen. If any one is cut off the fire will be put out. As the fire blanket completely surrounds the person whose clothes caught fire, it seals the person’s body surface around the fire and cut’s off the oxygen supply to the fire, thereby putting it out. Hence fire blanket acts as a fire extinguisher and stops the fire from spreading.
