Starving: limiting fuel by removing potential fuel from the vicinity of the fire, removing the fire from the mass of combustible materials or by dividing the burning material into smaller fires that can be extinguished more easily.
What is fire starvation?
Starvation is the process of depriving the fire of fuel, i.e. combustible materials. … Smothering is the process of depriving the fire of the oxygen needed to sustain the combustion process.
What is starving in extinguishing of fire *?
Starvation is the process of depriving the fire of fuel, i.e. combustible materials. Cooling is depriving the fire of heat, e.g. by applying a substance such as water that will absorb heat from the fire and reduce the temperature below the critical level needed to sustain the fire.
What is cooling in fire fighting?
Cooling. The most commonly used fire fighting medium is water. Water, referring to the triangle of fire, cools the heat being produced in the fire to below ignition temperature.
What extinguishes a fire by smothering?
By excluding the oxygen in the surrounding atmosphere, the fire will be extinguished. Smothering can be achieved by using sand, blanketing, foam application or by the use of chemical extinguishers.
What are the 3 methods of extinguishing a fire?
All fires can be extinguished by cooling, smothering, starving or by interrupting the combustion process to extinguish the fire. One of the most common methods of extinguishing a fire is by cooling with water.

When a fire is extinguished by the removal of oxygen it is said to have been?
Extinction of the fire
To stop a fire, one of the three elements of the fire triangle must be removed. So, if a fire runs out of fuel, it will smoulder out; if you can cool a fire down it will lose heat and go out; and if the oxygen is removed it will suffocate.
How can you stop fire?
In the kitchen
- Cover the fire with a heavy metal lid and turn off the heat source.
- Baking soda or salt can handle a small fire. Do not use water to put out the fire.
- Keep a B-Class dry chemical fire extinguisher around in case the fire grows.
- Call 911 if you can’t extinguish the fire, and GET OUT.
What are the 4 elements of extinguishment?
Essentially all four elements must be present for fire to occur, fuel, heat, oxygen, and a chemical chain reaction. Removal of any one of these essential elements will result in the fire being extinguished.
