What is the Critical Zone for Surgical Gown?
The barrier requirements for the design and construction of surgical gowns, other protective apparel are based on the anticipated location and degree of liquid contact, given the expected conditions of use. The critical zones include those areas where direct contact with blood, body fluids, and other potentially infectious materials, although areas outside of the critical zones can inadvertently be sprayed or splashed as well.
Critical Protection Zones for Surgical Gowns
The entire front of the gown (areas A, B, and C), including the seam and other components, is required to have a barrier performance of at least level 1.
The critical zone compromises at least areas A and B.
The back of the surgical gown (area D) may be non-protective.
