What are the three essentials needed in order for a fire to start and grow

  1. Fuel, helium and heat

  2. Fuel, oxygen and nitrogen

  3. Oxygen, heat and carbon dioxide

  4. Oxygen, heat and fuel

The correct answer is: Oxygen, heat and fuel

A fire needs three essential components to start and grow: oxygen, heat, and fuel. This is often referred to as the fire triangle. Oxygen is needed for any kind of combustion process to take place. In the case of a fire, it allows the process of combustion to continue and the fire to sustain itself. Heat is the second necessary part, it raises the material to its ignition temperature. The last ingredient is fuel, which is any kind of combustible material that the fire can use as a source of energy. Therefore, the combination of oxygen, heat, and fuel is necessary for a fire to start and grow.
