Question

Which of the following should be done to control fire?

• A. Reduce the heat supply
• B. Increase fuel supply
• C. Increase the oxygen supply
• D. Reduce the nitrogen supply

Answer 1

The correct option is A

Reduce the heat supply

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.
