20、2013 1(This foreword is not part of this standard. It is merely informative and does not contain requirements necessary for conformance to the standard. It has not been pro-cessed according to the ANSI requirements for a standard and may contain material that has not been subject to public review or

21、a consensus process. Unresolvedobjectors on informative material are offered the right to appeal at ASHRAE or ANSI.) FOREWORD The issue addressed here is to avoid placing a patient into a room that would cause a risk to staff or visitors due to undiagnosed infected individuals with gastrointestinal,

22、 respi-ratory, or skin pathogens. Since examination rooms are the first point of close physical contact with undiagnosed patients, these rooms have a higher risk than spaces that containpatients who have already been diagnosed. Addendum ad subdivides examination rooms beyond the current division of

23、emergency and nonemergency rooms and establishes air change rates commensurate with the riskwithin those specialized rooms. Administrative controls (such as assignment of patients to specialized rooms) are an important preventive strategy to supplement the benefit ofenvironmental controls. As such,

24、these administrative controlse.g., phone triage, prompt triage to an area away from others, and assignment to a special examination roomwould be applied to people presenting with undiagnosed gastrointestinal, respiratory, or skin infection symptoms. This room classification is one step in the contin

25、uum of protection from examination room to procedure room or operating room. Because the majority of examination roomswill not be required to protect staff and visitors from gastrointestinal, respiratory, or skin disease transmission, the air change rate requirements can be reduced in both total and

26、outdoor air volumes. This division of examination rooms is not applicable to emergency department examination rooms.Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and strikethrough (for deletions) unless the instructions specif-ically

27、 mention some other means of indicating the changes. AddendumadtoStandard170-2013Revised Table 7.1 as shown.

31、 IMPACT OF ITS ACTIVITIESASHRAE is concerned with the impact of its members activities on both the indoor and outdoor environment.ASHRAEs members will strive to minimize any possible deleterious effect on the indoor and outdoor environment ofthe systems and components in their responsibility while m

32、aximizing the beneficial effects these systems provide,consistent with accepted Standards and the practical state of the art.ASHRAEs short-range goal is to ensure that the systems and components within its scope do not impact theindoor and outdoor environment to a greater extent than specified by th

33、e Standards and Guidelines as established byitself and other responsible bodies.As an ongoing goal, ASHRAE will, through its Standards Committee and extensive Technical Committee structure,continue to generate up-to-date Standards and Guidelines where appropriate and adopt, recommend, and promotetho

34、se new and revised Standards developed by other responsible organizations.Through its Handbook, appropriate chapters will contain up-to-date Standards and design considerations as thematerial is systematically revised.ASHRAE will take the lead with respect to dissemination of environmental informati

35、on of its primary interest andwill seek out and disseminate information from other responsible organizations that is pertinent, as guides to updatingStandards and Guidelines.The effects of the design and selection of equipment and systems will be considered within the scope of thesystems intended us

36、e and expected misuse. The disposal of hazardous materials, if any, will also be considered.ASHRAEs primary concern for environmental impact will be at the site where equipment within ASHRAEs scopeoperates. However, energy source selection and the possible environmental impact due to the energy sour

37、ce andenergy transportation will be considered where possible. Recommendations concerning energy source selectionshould be made by its members. ASHRAE (www.ashrae.org). For personal use only.
