A barrier enclosure defines an aseptic chamber.

At least one containment barrier (14, 15, 16, 17) defines an isolation region (10).

The containment barrier of the containment zone is indicated with a black hatched line.

In high containment zones, the "clean" change area is located outside the containment barrier.

The containment barrier, which refers to the boundary between "clean" and "dirty" areas inside a containment zone, is sometimes distinct from the containment zone perimeter.

In addition, operators and owners shall ensure that no single failure of a containment barrier can lead to a major accident

The containment barrier is always encountered at or inside the containment zone perimeter.

Where MSIVs provide a containment barrier, they shall meet the containment requirements that apply to those conditions for which they are credited.
