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.
How do you put a fire out cooling starvation 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 method of extinguishing fire?
The basic methods for extinguishing a fire are to suffocate it by ensuring that it cannot have access to oxygen, to cool it with a liquid such as water which reduces the heat or finally to remove the fuel or oxygen source, effectively removing one of the three elements of fire.
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.
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.
What are the five main principles of fire?
Fire Extinguishment Principles
- Cooling of Flame.
- Reduction of Flame by cooling of the liquid; dilution of the liquid; or blanketing of the liquid.
- Reduction of oxygen.
- Interference with Combustion Reaction.
