2.1 GENERAL
All patient areas shall be body-protected electrical areas or cardiac-protected electrical areas.Body-protected electrical areas shall be in accordance with the requirements of this Section and Section 3. Cardiac-protected electrical areas shall be in accordance with the requirements of this Section and Section 4. See Clause 2.2.3 to determine where cardiac- protected electrical areas are required.All locations that form part of the facility and in which it is intended that low-voltage medical electrical equipment will be used on a patient and can be operated while connected to the electrical supply mains (except in emergencies) shall be signposted as body-protected or cardiac-protected electrical areas.
NOTE: Appendix A provides information in relation to planning of patient areas.In Australia, body-protected and cardiac-protected electrical areas shall not be provided in the same room.In New Zealand, notwithstanding the definitions in Clauses 1.5.4 and 1.5.5, body-protected and cardiac-protected electrical areas may be provided in the same room providing that—(a) the boundaries of the cardiac-protected electrical areas are clearly and permanently inlaid in the floor;(b) each socket-outlet in the cardiac-protected electrical area is separated by not less than 4000 mm from the nearest socket-outlet in the body-protected electrical area; and (c) the nominal patient location centres are separated by not less than 4000 mm.
2.2 CLASSIFICATION OF PATIENT AREAS
2.2.1 Documentation
Documentation outlining patient area locations and classifications shall be provided by the responsible organization/entity. The documentation shall—(a) identify the location of patient areas and whether they shall be classified as body-protected, or cardiac-protected areas; (b) identify the location of areas that are determined by the responsible organization/entity to not be classified as patient areas (where no medical electrical equipment is used on a patient), and shall provide justification thereof; (c) be readily available and retained at the premises; (d) be updated to record all alterations, repairs and changes of use in nominated patient areas, and any changes of use where non-patient areas become patient areas. NOTE: Where there is doubt about the intended use of a particular location, formal clarification should be sought from the responsible organization/entity, and the documentation updated accordingly.
2.2.2 Patient area boundaries
The boundary of the patient area extends to the walls and doors surrounding the patient locations. Where such walls are incomplete at the entry way(s) into a single clinical operational unit, those walls shall be extended to enclose the boundary as shown in Figure 4. Nursing stations, staff bases, beverage areas, etc. located within the patient area boundary are part of the protected electrical area.In New Zealand, the responsible organization/entity may determine that nursing stations, staff bases, beverage areas, etc. located within the patient area boundary may not be required to be wired as part of the protected electrical area. The following shall not be considered as boundaries: (a) Nib walls. NOTE: A nib wall is a short section of a wall that juts out from a building’s wall at the full height of the wall. (b) Partitions, dividers, screens, benches or moveable walls. (c) Curtains. NOTES: I Figure 3 illustrates the relationship between patient area, patient environment and patient location. 2 Clauses 2.4.3.2, 2.7.3, and 4.4.2.4 contain requirements for LPD protection and equipotential earthing of certain socket-outlets located outside patient areas. 3 See Clauses 2.4.3.2.2(b) and 4.4.2.4.1(a)(ii) for socket-outlets installed outside patient area.
2.2.3 Patient areas required to be wired as cardiac-protected electrical areas
A patient area shall only be wired as a cardiac-protected electrical area if cardiac-type procedures as determined by the responsible organization/entity are to be undertaken on a regular and routine basis. NOTES: I In emergency circumstances, local earthing protection will suffice if a cardiac-type procedure needs to be carried out in a body-protected electrical area. 2 Further advice on electrical safety precautions necessary during cardiac-type procedures is specified in AS/NZS 2500. The following areas shall be wired as cardiac-protected electrical areas if cardiac-type procedures are undertaken there: (a) Cardiac catheter laboratories. (b) Cardiac ICU. (c) ICU with regular thermodilution Swann-Ganz monitoring. (d) Neo natal ICU. (e) Operating theatres for cardiac surgery.
(f) CCU. Locations other than those listed above, in which cardiac-type procedures will be regularly performed, shall also he wired as cardiac-protected electrical areas. In such cases, the responsible organization shall provide documentation outlining the specific requirements.AS NZS 3003 pdf free download.
