What is starvation method in fire fighting?

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 the fire triangle?
