Question

Fire can be controlled by removing which of the following factors?
A. Fuel
B. Air
C. Heat
D. All of the above

Answer 1

Hint: The method of reducing a fire's heat output, reducing the area over which the fire exists, or suppressing or extinguishing a fire by limiting it of fuel, oxygen, or heat is known as fire control. The prevention, detection, and extinguishment of flames, as well as secondary activities such as research into the origins of fire, public education about fire hazards, and the maintenance and enhancement of fire-fighting equipment, are all part of fire prevention and control.

Complete answer:
The fire extinguisher is a device that firefighters use to put out fires. According to the fire triangle, three things must be present at the same time in order for fire to be generated. Fuel (anything that can burn), a heat source (which can ignite the fuel), and air are the three (for a constant supply of oxygen). So, if we take away any of these resources, we can put out the fire.
The oxygen and heat from the air raise the temperature of the fuel over the ignition point.
Any one of these components can be removed to control fire.
Hence, the correct option is D. All of the above.

Additional Information:
Class A fire extinguishers are for fires involving wood, paper, and plastic; Class B fire extinguishers are for liquid fires involving oils, gasoline, kerosene, and paint; and Class C fire extinguishers are for electrical equipment. It is critical to understand how a fire extinguisher works and where to point it while using one.

Note:
When it comes to electrical fires and flames caused by flammable substances, To put out a fire, we usually use a soda-acid fire extinguisher or a $C{O_2}$ fire extinguisher that cuts off the oxygen supply. We cannot always use water fire extinguishers to extinguish the fire.
