The study showed a significant risk to the school population during a weapons containment emergency. This will prevent the chemical toxins from entering the school through the cracks and other openings in the building.
Clean air is kept inside, toxic air is kept outside.
The air pressure is maintained by drawing the toxic chemical laden air from the exterior and forcing it through a sophisticated filtering system . Next, the purified and pressurized air then fills the school's protected haven where the children are. Finally, a surplus of purified and pressurized air is allowed to leak out of the building's cracks, eliminating the possible entry of contamination. In the event of an emergency, toxins will be removed from the air by the carbon adsorbers within this unit, thereby protecting the school children from danger. In the event of an emergency, the school's containment area will be pressurized by the air blower within this unit.
