Collective protection is an important aspect of fixed site defense.
Ideally, it provides a contaminate free environment for people, allowing relief from the continuous wearing of gas masks and other
MOPP equipment.
The basic concept applied for collective protection is
overpressure and filtration.
By filtering the incoming air to the shelter or protected space and maintaining higher internal air pressure than the external pressure, the contaminated external air is prevented from infiltrating the shelter or protected space and results in a toxic free area (TFA) for work and relief from wearing MOPP equipment.
The most critical component of any collective protection area is the air filtration system. The US
Army Corps of Engineers has published stringent standards for the construction and performance of this type of equipment.
