Preface:This is the fifth edition of CSA Z32,Electrical safety and essential electrical systems in health care facilities. It supersedes the previous editions, published in 2015, 2009, 2004, and 1999, and is harmonized with CSA C22.1,Canadian Electrical Code, Part I, and CSA C282,Emergency electrical power supply for buildings.This edition features several important revisions. Table 6 has been updated to be harmonized with CSA Z8000,Canadian health care facilities, and similar health care facility standards. An informative Annex has been added to suggest a sequence of testing when performing the tests within this Standard. The test methods in Clause 5 have been updated.CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of the governments of Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, Nunavut, Ontario, Prince Edward Island, Québec, Saskatchewan, and Yukon, as administered by the Canadian Agency for Drugs and Technologies in Health (CADTH).This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope:1.1 General1.1.1 ApplicationThis Standard deals with the following subjects:a) electrical safety associated with health care provision; andb) essential electrical systems for health care facilities.Note:See Clause 3 for the definition of "health care facility".1.1.2 Exclusions1.1.2.1 Veterinary facilitiesThis Standard is not intended to apply to veterinary facilities, although its electrical safety principles could prove useful in the design, construction, and operation of such facilities.1.1.2.2 Uninterruptible power systemsUninterruptible power systems (UPS), which may be used for specific critical applications, are not covered by this Standard.Note:If a UPS is used within a health care facility, refer to Annex K for more information.1.1.3 Relationship to theCanadian Electrical CodeProvisions of this Standard are supplementary to the installation requirements specified in Sections 24 and 52 of CSA C22.1,Canadian Electrical Code, Part I, and require compliance withCanadian Electrical Code, Part IIstandards.1.2 Electrical safety1.2.1 AreasThis Standard applies toa) patient care areas of Class A, Class B, and Class C health care facilities; andb) areas outside health care facilities that are intended for patient diagnosis, treatment, or care involving intentional electrical contact of any kind between patients and medical electrical equipment.1.2.2 Electrical equipmentThis Standard applies toa) medical electrical equipment;b) health-care-facility-owned non-medical electrical equipment;c) patient-owned electrical devices; andd) the use and management of the equipment and installations in patient care areas.The electrical equipment described in Items a) to c) can be portable or permanently connected.1.2.3 Aspects of electrical safetyThis Standard deals principally with safety from the hazards of electric shock (see Annex A). Other aspects of electrical safety, such as fires and interference with proper operation, are also addressed. Note:TheCanadian Electrical Code, Part I,specifies the minimum requirements for a safe building electrical installation for supplying utilization equipment in patient care areas, but does not specify requirements for the number, arrangement, and circuit loading of branch circuits and receptacles required for the procedures to be performed. Neither does it state requirements for the use and maintenance of such installations. This Standard builds on the requirements of theCanadian Electrical Code, Part I,and provides this additional information.1.2.4 Medical risks or benefitsThe medical purposes, risks, or benefits of procedures or equipment are the professional responsibility of health care practitioners and, therefore, are beyond the scope of this Standard, which provides general guidelines to ensure the safe use of electrically operated equipment.1.3 Building electrical installationsThis Standard applies to electrical installations in patient care areas of health care facilities.1.4 Essential electrical systemsClause 6 applies to the design, installation, operation, and maintenance of the normal and emergency supply required to provide electrical power to those portions of a health care facility's electrical system in which the interruption of the normal supply can jeopardize effective and safe patient care, the safety of health care facility staff, and public safety. Aspects of emergency electrical power supply systems not covered by Clause 6 are covered by CSA C282.UPS units are not considered an emergency supply source in accordance with Clause 6 of this Standard and in accordance with Rule 24-306 of theCanadian Electrical Code, Part I.Note:Some health care facilities have added, or are considering adding, UPS to essential electrical systems to provide improved supply continuity for specific areas or equipment. Annex K describes factors that should be considered by health care facility administration for use of UPS.1.5 TerminologyIn this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
