Emergency electrical service shall be provided for use in the event of failure of the normal electrical service.  This emergency service shall be made up as follows:

(1)           In any existing facility, the following must be provided:

(a)           type 1 or 2 emergency lights as required by the North Carolina State Building Code;

(b)           additional emergency lights for all nursing stations, drug preparation and storage areas, and for the telephone switchboard, if applicable;

(c)           one or more portable battery‑powered lamps at each nursing station; and

(d)           a suitable source of emergency power for life‑sustaining equipment to ensure continuous operation for a minimum of 72 hours.

(2)           Any addition to an existing facility shall meet the same requirements as new construction.

(3)           Any conversion of an existing building such as a hotel, motel, abandoned hospital or abandoned school, shall meet the same requirements for emergency electrical services as required for new construction.

(4)           Battery‑powered corridor lights shall not replace the requirements for the emergency circuit nor be construed to substitute for the generator set.  Sufficient fuel shall be stored for the operation of the emergency generator for a period not less than 72 hours, on a 24‑hour per day operational basis.  The system shall be test run for a period of not less than 15 minutes on a weekly schedule.  Records of running time shall be maintained and kept available for reference.

(5)           To ensure proper evaluation of design of emergency power systems, the owner or operator shall submit with final working drawings and specifications a letter describing the policy for admissions and discharges to be used when the facility begins operations.  If subsequent inspections for licensure indicate the admission policies have been changed, the facility will be required to take immediate steps to meet appropriate code requirements for continued licensure.

(6)           Lighting for emergency electrical services shall be provided in the following places:

(a)           exit ways and all necessary ways of approach exits, including exit signs and exit direction signs, exterior of exits exit doorways, stairways, and corridors;

(b)           dining and recreation rooms;

(c)           nursing station and medication preparation area;

(d)           generator set location, switch‑gear location, and boiler room, if applicable; and

(e)           elevator, if required for emergency.

(7)           The following emergency equipment which is essential to life, safety, and the protection of important equipment or vital materials shall be provided:

(a)           nurses' calling system;

(b)           alarm system including fire alarm actuated at manual stations, water flow alarm devices of sprinkler systems if electrically operated, fire detecting and smoke detecting systems, paging or speaker systems if intended for issuing instructions during emergency conditions, and alarms required for nonflammable medical gas systems, if installed;

(c)           fire pump, if installed;

(d)           sewerage or sump lift pump, if installed;

(e)           one elevator, where elevators are used for vertical transportation of patients;

(f)            equipment such as burners and pumps necessary for auxiliaries and controls, required for heating and sterilization, if installed; and

(g)           equipment necessary for maintaining telephone service.

(8)           Where electricity is the only source of power normally used for space heating, the emergency service shall be provided for heating of patient rooms.  Emergency heating of patient rooms will not be required in areas where the facility is supplied by at least two separate generating sources, or a network distribution system with the feeders so routed, connected, and protected that a fault any place between the generators and the facility will not likely cause an interruption.

(9)           The emergency electrical system shall be so controlled that after interruption of the normal electric power supply, the generator is brought to full voltage and frequency and connected within ten seconds through one or more primary automatic transfer switches to all emergency lighting, alarms, nurses' call, equipment necessary for maintaining telephone service, and receptacles in patient corridors.  All other lighting and equipment required to be connected to the emergency system shall either be connected through the ten second primary automatic transfer switching or shall be subsequently connected through other automatic or manual transfer switching.  Receptacles connected to the emergency system shall be distinctively marked for identification.
