Question

Which of the following should be done to control fire?


Increase the oxygen supply

Increase fuel supply

Reduce the heat supply

Reduce the nitrogen supply


​

Answer 1

Answer:

reduce the heat supply because when atmosphere become cool then fire can be controlled

Answer 2

Answer:

(C) Reduce the heat supply

Explanation:

The diagram given represents what is called the fire triangle which shows that oxygen, heat and fuel in the proper proportions are necessary to create a fire. Reducing or eliminating any or all of these properly can help in containing or stopping the fire.

So in order to stop a fire,

1. Heat should be reduced – this decreases the temperature of fuel below ignition temperature thus stopping the fire.

2. Oxygen should be cut off – lack of Oxygen will stop the combustion.

3. Fuel should be limited – Decreasing the quantity of fuel available for combustion can help contain it.
