The space shown in Figure 2 extending laterally 1.5 m around all possible patient locations to height of 2.5 m in a cardiac-protected electrical area.
Where adjacent patient environments overlap, the combined area is deemed one patient environment. A patient environment may contain one or more patient locations.
The patient environment does not extend through walls.
NOTES:
1 The patient environment is intended to embrace all locations within a cardiac-protected electrical area in which intentional or unintentional electrical contact could occur between the patient and any other object, directly or via another person touching the patient and the object.
2 Every possible location of the patient should be considered when determining the extent of the patient location.
3 Figure 3 illustrates the relationship between patient area, patient environment and patient location.Each socket-outlet or each item of permanently wired electrical equipment. A multiple combination socket-outlet is regarded as the same number of points as the number of integral socket-outlets in the combination.
Prospective hazard current is current that would flow, in a transformer-isolated supply,between one of the active conductors and earth if the active conductor were solidly bonded to earth.
NOTE: Although prospective hazard current does not flow until a line-to-earth fault occurs, a line can be described as having a prospective hazard current of a particular value because the cumulative effect of the imperfections in the line isolation will cause current to flow as soon as a line-to-earth fault occurs.
The organization/entity responsible for the authorization of the design/redesign,installation/refurbishment, associated infrastructure, use and maintenance of the premises and/or those responsible for medical electrical equipment, a medical electrical system and medical electrical installation.
NOTES:
1 For example, the entity may be a hospital or an individual clinician. The owner, operator and responsible entity may be the same person.
2 For example, the entity may manage patient care in any facility including the home, the government as the owner of the facility, or a private operator of a facility which requires body-protected or cardiac-protected electrical areas.
3 Education and training facilities are to be considered.AS NZS 3003 pdf free download.
