This proposed addendum subdivides examination rooms beyond the current division of emergency and non-emergency rooms and establishes air change rates commensurate with the risk within those specialized rooms. Administrative controls (such as assignment of patients to specialized rooms) are an important preventive strategy to supplement the benefit of environmental controls. As such these administrative controls would be applied to people presenting with undiagnosed gastrointestinal, respiratory, or skin infection symptoms, e. g. phone triage, prompt triage to an area away from others, and assignment to a Special Examination Room.
