The ITCS is a collective, unhardened CBRN protection system (NATO Stock No. 7690-17-113-1929) that can simply and quickly transform existing infrastructure (such as homes, schools, or military outposts, etc.) into a Toxic Free Area (TFA). The system protects against NBC threat and from toxic chemicals such as tear gas, smoke, and other forms of air pollution. The ITCS is also capable of being erected outside of a building or tent.
