Cardiac arrest Respiratory arrest Burning Denervation Ulceration d. Magnitude of the current Duration of current flow Current path. Microshock Current passing through the body via direct electrical contact with the heart. Burning, denervation and possibly ventricular fibrillation may occur depending on the magnitude and path of the current. Cardiac standstill and massive burning may occur in high voltage shocks e.

The possibility of macroelectrocution is exacerbated with the application of medical electrical equipment when: May occur when an electrode wire, electrolyte-filled catheter or transducer is introduced into direct contact with ventricular heart muscle. Safe equipment design needed: Patient area must be wired as CPA. Safe equipment application needed: Flexible protective earthing conductors must be intact. Hospital must control leakage currents when assembling trolley- mounted medical electrical systems.

Electrical installation work must be carried out by licensed electrical workers. Electrical installation work includes: Installing fixed electrical equipment. We are consulting engineers — not lawyers. Legal questions may need to be discussed with a state electrical authority or a lawyer. Was not a legal requirement when first published in Became a requirement of hospital building contracts.

Became a requirement of medical and allied health professional bodies e. Became a legal requirement in Victoria in May be a duty of care under occupational health and safety legislation or common law. Broad acceptance of legal requirements is inhibited by: Excessive requirements aas the edition of the standard. Lack of action by state electrical authorities.


Fixed means secured, attached or connected by conduit, metal ss, duct, bolt, screw, clip, other fastening device or fixed wiring. Fixed means secured, attached or connected by conduit, metal pipe- work, duct, bolt, screw, clip, other fastening device or fixed wiring.

Wall-mounted X-ray viewing boxes. Still requires patient areas to be wired as: Wherever mains powered medical electrical equipment is used. Patient areas must still be wired as: Some high risk medical electrical equipment.

Socket-outlet colours unchanged except for some generator-backed circuits. Requirements for EP equipotential earth wiring in CPAs similar to edition — but with better drawings.

New definition of essential supply. Certain patient areas must only be BPAs. Certain patient areas must be CPAs. LPD protection and EP earthing of socket-outlets outside patient areas: Has been extended from 2 m to 5 m from each entry. Is now required with or without a door.

Final sub-circuits may only supply one 303 and its ensuite. Final sub-circuits may no longer supply socket-outlets for cleaning purposes and other socket-outlets. Socket-outlets requiring LPD protection clearly specified: RCDs must now be: Inaccessible socket-outlets must now have readily accessible isolating switches.

Socket-outlets for cleaning purposes aas only required near BPAs. EP terminals no longer required in CPAs. New requirements for special patient areas: Home installations for haemodialysis.

Home installations for other medical electrical equipment. Self harm areas e. New requirements for alterations, additions and repairs to electrical installations in patient areas: Maximum field strength specified for some not all patient areas intended for ECG monitoring and recording. Requirements apply prior to commencing work, and on completion of work. Requirements apply to new bzs areas and to alterations.

Full technical requirements for routine inspection and testing. Other aged care facilities. This does not include areas such as corridors and lifts where medical equipment is only used in an emergency or for transporting patients. The standards applies wherever mains powered medical electrical equipment is used. The standard only applies in areas intended for the regular use of medical electrical equipment.

Where a room is intended for medical electrical equipment that will be connected to a patient in another room, both rooms are patient areas For example: Cardiac cath lab recording room with physiological recorder. Sleep lab recording room. CT control room with injector control unit.

Socket-outlets outside CPAs used to nxs Capable of being reached quickly and without climbing over or removing obstructions, standing on a chair or using a ladder, and Not more than 2 m above the ground, floor or nza.

RCDs must a be readily accessible and not mounted under benches, in cupboards or cabinets, or behind heavy equipment. Socket-outlets require LPD protection if they are accessible — not just readily accessible — without a tool. Socket-outlets that are not readily accessible must have readily accessible isolating switches or a dedicated LPD.

Permanently wired appliances protected by LPDs that also protect socket-outlets or other appliances must have readily nas isolating switches. One or more socket-outlets contained within one surround. No longer a group: Where the walls of a BPA are incomplete e.

Parent international standard for MEE. Time line leading to the publication of Ed 3: Ed 1 of IEC published inclosely followed by Ed 1 of the parent standard. Ed 2 of IEC published in A substantive 2nd amendment to to the Ed 2 of IEC was published in Ed 3 of the parent nzz published sa December In this context, the following are not considered walls or boundaries: Many generator-backed outlets are no longer on essential supplies ESV has issued exemptions allowing additional red socket-outlets on circuits subject to load shedding under programmable load nzss.

Cardiac catheter laboratories and control rooms. ICU with regular thermodilution Swann-Ganz monitoring. Neo natal ICU Level 3. Operating theatres for cardiac and thoracic surgery. Other locations intended for regular or routine cardiac-type procedures. No mention of wards.

Accident and emergency wards. Chiropractic and physiotherapy rooms.

Recovery areas or wards associated with operating theatres and imaging rooms. Endoscopy theatres and procedure rooms. General medical and surgical wards. X-ray rooms Except cardiac cath labs!
