our model: nature
The atmosphere we breathe consists mainly of a mixture of nitrogen (78%) and oxygen (21%). Nitrogen is an inert gas. Oxygen is the natural substance aiding every combustion process, including human respiration. A fire will exist only if sufficient oxygen continuously reaches it to support the speed of the reaction.
When the amount of oxygen is not sufficient, a fire will suddenly be extinguished. The methodology N2 FireFighter® is based on that principle: to keep the atmosphere in the areas to be protected low in oxygen, less than normal ambient. This will automatically extinguish and inhibit combustion while remaining safe for humans.
The effect of this auto-extinguishing atmosphere on humans is the same as the air we find on the mountains at about 3.300 m elevation; the partial pressure of oxygen at that height is equal to the partial pressure of oxygen in the methodology of N2 FireFighter®.
